Obviously needed is a comprehensive and rigorous revision that includes morphological as well as molecular and larval characters. As far as morphological characters are concerned, stress should be placed on biologically significant structures such as those directly involved in reproduction, as in the case of the external reproductive structures (see Reproductive structures and the taxonomy of the Goneplacidae, p. 755). There is, however, very limited information on the larval development of goneplacids, knowledge that has so far shed little light on the phylogenetic relationships of the taxa comprising the family (see Rice 1980: 337, 354; Wear &amp; Fielder 1985:62). The same can be said about the molecular characterizations of goneplacids.</p> <p>A comprehensive revision of the taxa included here as comprising the Goneplacidae (i.e. Goneplacinae [including Carcinoplacinae]) may ultimately show that some or all of these taxa are perhaps best treated as independent families under the superfamily Goneplacoidea, an arrangement already followed by d’Udekem d’Acoz (1999), and in part by Števčić (2005) and Karasawa &amp; Schweitzer (2006), who raised the Goneplacinae to family status (see Remarks for subfamily Goneplacinae below). The question of which taxa actually make up the Goneplacidae is unfortunately not as “simple” as indicated by Števčić (2005: 138). Not all taxa included in his conception of the family share, for instance, the interrupted sternal sutures 4/5 to 7/8 and the “long G2” as stated. The presence of additional, strong synapomorphies should clearly establish, or challenge, the monophyly of the family.</p> <p>The subfamily Euryplacinae is treated here as a family independent of the Goneplacidae, a status previously suggested by Guinot (1969b) and followed by Števčić (2005) and Karasawa &amp; Schweitzer (2006). Prominent among its diagnostic characters are the conspicuously narrow male abdomen, slender and long G1, and short G2 (see Ng &amp; Castro 2007). Table 2 summarizes the most important diagnostic characters of the Euryplacidae in comparison with those of the subfamilies of the Goneplacidae sensu stricto, including the Carcinoplacinae, which is treated here as part of the Goneplacinae.</p> </div>	https://treatment.plazi.org/id/102B87CBFF84256BFD61FBA6FDC0FE8E	Public Domain	No known copyright restrictions apply.

Dorsal surface smooth or marked with variously distinct regions. Single anterolateral tooth posterior to outer orbital angle, sometimes obsolete. Notch between frontal margin, inner edge of supraorbital border typically slight. Orbits moderately to conspicuously wide, fissure typically absent.

Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6 interrupted medially, 6/7, 7/8 interrupted medially or complete. Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Prolongation of male episternite 7 present; thoracic sternite 7 laterally covered with thoracic sternite 8; thoracic sternite 8 without supplementary plate, portions of varying size left visible or not by abdomen. Cheliped (P1) fingers varying from dark to light in colour; ambulatory legs (P2-P5) compressed. Male abdomen with 6 freely articulated somites plus telson; narrower than sternum, somite 3 being narrower than thoracic sternite 7; telson slightly longer than wide. Abdominal-locking mechanism with medium-size button on edge of thoracic sternite 5 pairing with shallow socket on underside (ventral surface) of abdominal somite 6. Male opening coxal, with soft, free penis arising directly from P5 coxa but protected by sternum for a short distance (coxosternal condition). G1 slender or stout, typically with truncated tip. G2 long, typically with long flagellum (short in a few species). Female abdomen with 6 freely articulated somites plus telson; locking mechanism with medium-size button on edge of thoracic sternite 5 in immature individuals; vulva of varying size on thoracic sternite 6, vulvar cover may be present.</p> <p>REMARKS</p> <p>As part of the Goneplacidae sensu Balss 1957, the subfamilies Goneplacinae and Carcinoplacinae were traditionally separated by the shape of their respective carapaces. The typical carcinoplacine carapace, represented by Carcinoplax, is subquadrate, with orbits that are not excessively elongated (or “normal”) so that the widest breath of the carapace is at the level of the anterolateral borders, a shape often referred to as “xanthoid”. In contrast, the typical goneplacine carapace, as in Goneplax, is transversely rectangular and has its widest breadth typically at the level of the outer orbital angles as a result of conspicuously elongated orbits to accommodate long eye peduncles. An almost identical goneplacine carapace also appears among some members of the Euryplacidae (such as Frevillea A. Milne-Edwards, 1880, and Trapezioplax Guinot, 1969), clearly not members of the Goneplacinae as evidenced by the morphology of their respective male abdomens, G1, and vulvae (see discussion of Psopheticoides Sakai, 1969, p. 620). As in other groups of brachyuran crabs, carapace shape is not always a reliable synapomorphy.</p> <p>Guinot (1971: 1081, footnote) precisely explained that the separation between Carcinoplacinae and Goneplacinae was more a matter of convenience and that the distinction between the two taxa “ne sera peut-être pas justifiée dans une classification peu découpée”. Although the morphometry of the carapace conveniently separates some genera, carapace shape and the relative length of the orbits are clearly intermediate between the two extremes in the case of Psopheticus Wood-Mason, 1892 and Exopheticus n. gen. The absence of a clear distinction among other characters, such as the morphology of the male abdomen and its relation to the thoracic sternum, and the morphology of the G1 and vulva, do not support the traditional dichotomy (see Table 2).</p> <p>The Carcinoplacinae was synonymized with Goneplacinae by Karasawa &amp; Kato (2003a, b) based on the cladistic analysis of characters among recent and fossil genera included or purportedly related to the Goneplacidae. Their hypothesis is supported by the original “ Goneplacidae carcinoplaciens-gonéplaciens (Carcinoplacinae + Goneplacinae)” line of Guinot (1969b) and more recently by Karasawa &amp; Schweitzer (2006). The present work also supports Karasawa &amp; Kato’s hypothesis, and the two subfamilies are thus treated as one. An alternate hypothesis is the creation of at least three subfamilies for the Carcinoplacinae (see Karasawa &amp; Kato 2003a, b); another is the elevation of the subfamilies of the Goneplacidae to full family status, as originally done by Ortmann (1894) and more recently by d’Udekem d’Acoz (1999) and Karasawa &amp; Schweitzer (2006) and in part by Števčić (2005). For Karasawa &amp; Schweitzer (2006) the Goneplacidae consists of only one subfamily so in essence the Goneplacinae was raised to family status.</p> <p>Five genera that have been placed at one time or another in the Carcinoplacinae or Goneplacidae are herein excluded from the Goneplacinae sensu stricto. The inclusion in the Goneplacidae of the first four genera listed below is questionable at best, but for the time being, these four genera are herein retained in the superfamily Goneplacoidea.</p> <p>Bathyplax A. Milne-Edwards, 1880, a monotypic Western Atlantic genus, has a carapace not unlike that of Carcinoplax. It has one anterolateral tooth and a conspicuous outer orbital tooth. The G1 is slender, the G2 about half the length of the G1. The vulva is round and large but not as large as in Carcinoplax, and partially covered by a vulvar cover in large females. The orbits and eyes are short. Although these characters may be found in some goneplacids, Bathyplax shows similarities to various other groups. Guinot (1969c, 1978), Manning &amp; Holthuis (1989), and Tavares (1996) have discussed its affinities to the families Geryonidae Colosi, 1923, and Xanthidae MacLeay, 1838, although they did not explicitly recommend its transfer to any of these two families.</p> <p>Conleyus Ng &amp; Ng, 2003, a monotypic Western Pacific genus, has a flattened, ridged, and bidentate carapace with superficial similarities to Intesius Guinot &amp; Richer de Forges, 1981, which together with Mathildella Guinot &amp; Richer de Forges, 1981, has been allied to the Goneplacidae. The male holotype (cl 12.2 mm, cw 16.4 mm; UF 2098) and male paratype (cl 7.1 mm, cw 9.4 mm; ZRC 2002.175) show the unusually reduced orbits, eye peduncles, and eyes (Ng &amp; Ng 2003: figs 2, 4A, B), which are not typical goneplacine characters and which were considered adaptations to its presence in rubble at moderate depths (30-67 m). The G1 of Conleyus (Ng &amp; Ng 2003: fig. 5D-F) has similarities to the stout G1 of Pycnoplax n. gen. and Thyraplax n. gen. but it is shorter, thinner, the tip is slightly flared, and the terminal spinules much smaller than in the two goneplacine genera. The G2 is long but it has a short flagellum and lacks the slightly-expanded tip with one or more spinules often seen in the G2 of goneplacines. The male abdomen is not typically triangular as in goneplacines, somites 5 and 6 being distinctively narrower than somite 4 (Ng &amp; Ng 2003: fig. 5D). The morphology of the vulva remains unknown since the species is known only from two males. The anterior portion of the thoracic sternum (Ng &amp; Ng 2003: fig. 5A) is narrower than in goneplacines and there is a complete and well developed 3/4 suture, a character absent in the Goneplacidae. Conleyus was included in the Carcinoplacinae by Ng &amp; Ng (2003) but removed from the Goneplacidae and placed, without explanation, in the superfamily Conleyodea [sic], family Conleyidae by Števčić (2005). Ng &amp; Manuel-Santos (2007) kept the genus in an independent family within the superfamily Goneplacoidea.</p> <p>Paragalene Kossmann, 1878, a monotypic genus from the Mediterranean Sea, has a carapace with a superficial resemblance to Carcinoplax. Somites 3 and 4 of the male abdomen are fused, however, and the long flagellum of the G2 is serrated (Guinot 1969c: fig. 103). Guinot (1969c: 696) tentatively included the genus in the family Geryonidae Colosi, 1923. Although Števčić (2005) kept Paragalene in Geryonidae, Karasawa &amp; Schweitzer (2006: 55) stated that the genus “might be assigned to the Mathildellidae ” but solely on account of its carapace.</p> <p>Progeryon Bouvier, 1922, with four Indo-West Pacific species, has a carapace similar to that of geryonids. Nevertheless, all somites of the male abdomen are mobile (somites 3-5 fused and immobile in Geryonidae) and the G1 and G2 are similar to those of some goneplacines (see Ng &amp; Guinot 1999). Sutures 4/5 to 6/7 are incomplete, thoracic sternite 8 is not visible ventrally, and the abdomen covers the space between the P5 coxae. The systematic position of Progeryon is a controversial one (see Karasawa &amp; Schweitzer 2006: 35, 55). More recently, it has been listed as incertae sedis in the family Goneplacidae by Karasawa &amp; Kato (2003a), in the tribe Progeryonini of the family Geryonidae Colosi, 1923, by Števčić (2005), and in the Progeryonidae Števčić, 2005, by Karasawa &amp; Schweitzer (2006). Ng &amp; Manuel-Santos (2007) kept the genus in its own family, the Progeryonidae, within the superfamily Goneplacoidea.</p> <p>Psopheticoides Sakai, 1969, a monotypic Western Pacific genus, is being referred to the Euryplacidae. The examination of numerous specimens of Psopheticoides sanguineus Sakai, 1969, from the Philippine Is and Tonga, all deposited at ZRC and MNHN, show a slender male abdomen, a deep steno-abdominal cavity, a slender G1 with pointed tip and armed with spinules, a short G2 that is much shorter than the G1, a relatively long penis that lies in a concave thoracic sternite 8 before joining the G1, a relatively narrow female abdomen where the distal border of the thoracic sternites are left uncovered, and a thoracic sternite 8 that is concealed from dorsal view. The examination of these specimens is part of an ongoing revision of the Euryplacidae and related genera.</p> </div>	https://treatment.plazi.org/id/102B87CBFF8B2569FF27FE7FFCAEF97B	Public Domain	No known copyright restrictions apply.

Notch between front, inner edge of supraorbital border distinct, very slight, or absent; orbits narrow, not expanded distally; supraorbital borders slightly sinuous; suborbital borders rounded, with short, blunt inner tooth not visible dorsally; anterolateral borders convex. Dorsal surface of carapace typically smooth (slight horizontal ridges in some species), moderately convex, without clear indication of regions. Outer orbital angle with tooth, elongated prominence, or unarmed; 2 (3 in rare cases when outer orbital tooth detached from outer orbital angle is included; one in C. ischurodous) anterolateral teeth on each side of carapace (no teeth in large specimens of few species). Basal antennal article short, slender, distalmost (third) article reaches front. Eye peduncles short, much shorter than front (0.2-0.3 front width); cornea spherical, only slightly expanded distally. No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 6/7, 7/8 interrupted medially (Fig. 1). Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers moderately slender or thick, shorter than propodus, darker in colour in most species; carpus with tooth on inner margin. Dorsal margins of meri, carpi, propodi of ambulatory legs (P2-P5) unarmed (except P2 merus of C. spinosissima); dactyli slender, smooth, setose. Male abdomen with 6 freely-movable somites plus telson, narrowly triangular, somites 4-6 gradually decreasing in width from somite 3 (widest somite). Telson about as long as wide. Somite 3 covers space between P5 coxae, somite 2 slightly narrower than or as narrow as somite 3 so that somites 1, 2 leave small, often triangular portion of thoracic sternite 8 visible (Guinot 1969b: fig. 61; 1989: fig. 2; Hsueh &amp; Huang 2002: figs 7B, 9C, 10B), or somite 2 much narrower than somite 3 leaving a larger portion of thoracic sternite 8 visible (C. monodi; see Guinot 1969b: fig. 65, as C. indica; Guinot 1989: fig. 3). G1 long, slender, thin, straight or slightly sinuous, only slightly broadened proximally; truncated or pointed, thin tip. G2 slender, slightly longer than or as long as G1, flagellum shorter than proximal part (peduncle), slightly-expanded tip with 1 or 2 (rarely 3) spinules. Penis arising from P5 coxa, moderate size; broad, soft proximal expansion. Female abdomen with 6 freelymovable somites, wide. Telson wider than long. Somite 3 covers space between P5 coxae, somite 2 narrower than somite 3 so that somites 1, 2 leave small, often triangular portion of thoracic sternite 8 visible, or somite 2 as wide as somite 3 so that thoracic sternite 8 not visible. Vulva of mature females (Fig. 1) greatly expanded, extending from suture 5/6 to suture 6/7, covered by soft membrane, vulvar cover absent.</p> <p>REMARKS</p> <p>The history of the genus Carcinoplax was summarized by Serène &amp; Lohavanijaya (1973: 62) and Guinot (1989: 267). The genus was described as Curtonotus by de Haan (1833) for Curtonotus longimanus and C. vestitus (= Entricoplax vestita n. comb.), both from Japan. Curtonotus was preoccupied and consequently replaced by Carcinoplax by H. Milne Edwards (1852: 164). Additional species were described, which were progressively listed by Tesch (1918) and Balss (1957). The status of some of the species remained questionable, mostly because of changes in the shape of the carapace and the size of the chelipeds (P1) with age. Barnard (1950: 287), for instance, doubted the validity of the seven species from the Philippine Is described by Rathbun (1914). Serène &amp; Lohavanijaya (1973: 63) commented on the status of some of the species and gave a key to 17 species, of which seven do not belong to Carcinoplax sensu stricto, one (C. verdensis Rathbun, 1914) proved to be a junior synonym of another (C. specularis Rathbun, 1914), and a ninth species (C. angusta Rathbun, 1914) actually belongs in another family.</p> <p>The heterogeneous nature of the genus was recognized by earlier workers. Sakai (1969: 269) recognized three groups among the 17 species he listed but solely based on the morphology of the orbits and the anterolateral teeth. This was a very artificial grouping since species with very different G1, G2, male abdomens, and vulvae were placed together in the same groups. Guinot (1969b: 524) similarly recognized three groups (plus the unique status of some species), which were different from those of Sakai (1969). Although far more significant characters such as the G1, male abdomens, and thoracic sternites were considered, it was concluded that it was premature to create sub-generic or other taxa (“catégories sousgénériques ou autres”) for the genus since several species had not been examined by her. Guinot (1989) made the only revision of the genus so far, listing a total of 28 species, seven of which were not examined.</p> <p>The status of several species described under Carcinoplax nevertheless remained problematic. Serène &amp; Vadon (1981: 127) listed two unidentified species that presumably were new. Their Carcinoplax sp. A appears to indeed belong in Carcinoplax based on their description of the G1. Carcinoplax sp. B, however, most probably belonged in Pycnoplax n. gen. because, as pointed out (Serène &amp; Vadon 1981: 127), the G1 was of the same type as that of C. bispinosa Rathbun, 1914 (= Pycnoplax bispinosa n. comb.) and C. surugensis Rathbun, 1932 (= P. surugensis n. comb.). No “ Carcinoplax sp. A and B” specimens could be found in the MNHN collections.</p> <p>Carcinoplax angusta Rathbun, 1914 does not belong to Carcinoplax sensu stricto. This species was described from specimens collected in the Philippine Is, a female holotype (23.8 × 27.6 mm, USNM 46166; see Guinot 1989: fig. 39, pl. 12, figs A-E) and a pre-adult male (10 × 10.8 mm, same catalogue number). Most of the unique characters that separate C. angusta from Carcinoplax sensu lato were nevertheless clearly outlined by Rathbun (1914: 142): narrow male abdomen; slightly bilobed front; oblique supraorbital borders; sub octagonal, convex carapace; inner margin of suborbital bor- der with a “very large and prominent” tooth; and two small anterolateral teeth (first being a “blunt tooth or large tubercle”). The G1 is slender and the distal portion provided with small spinules (Zarenkov 1972: fig. 6-4; Guinot 1989: fig. 39D; Chen 1998: fig. 6-7, as C. angustata [sic]) and the G2 is much shorter than the G1 (Chen 1998: fig. 6-8, as C. angustata [sic]). The sterno-abdominal cavity of males is conspicuously deep. The penis is relatively long, much longer than in Carcinoplax, and it lies in a concave thoracic sternite 8 before joining the G1. The thoracic sternite 8 is not visible from dorsal view. Females have a relatively narrow abdomen and the vulva is large and round (though not as large as in Carcinoplax) and surrounded by a thick lip. All of these characters clearly separate C. angusta from other species of Carcinoplax sensu stricto and from the other goneplacine genera being described as new. These characters support the inclusion of C. angusta in the family Euryplacidae (see Table 2).</p> <p>A species morphologically similar to C. angusta, C. microphthalmus Guinot &amp; Richer de Forges, 1981, was described from a very large male holotype (53.3 × 61.4 mm, MNHN-B 6832; Guinot &amp; Richer de Forges 1981a: pl. 6, figs 1, 1a) and eight male and one female paratypes, also of large size (33.1 × 37.0 mm to 53.2 × 61.8 mm, MNHN-B 6828-6831, 6833; Guinot &amp; Richer de Forges 1981a: pl. 6, figs 2, 3), all from New Caledonia.</p> <p>Carcinoplax microphthalmus differs from Carcinoplax sensu stricto and from other new goneplacine genera in having a narrow male abdomen (Guinot &amp; Richer de Forges 1981b: fig. 9C), very slender and long G1 with a pointed tip (Guinot &amp; Richer de Forges 1981b: fig. 10E-G), and a relatively narrow female abdomen, all suggesting affinities to the Euryplacidae. The G2, however, is as long as or slightly longer than the G1 (Guinot &amp; Richer de Forges 1981b: fig. 10H) as in Carcinoplax sensu stricto, although the flagellum is as long as the proximal part, not shorter as in Carcinoplax. Also unlike Carcinoplax is a small vulva that is partially covered by a thick vulvar cover, a structure that appears to be absent among euryplacids. Other differences from typical euryplacids are the absence of many small denticles on the G1 and a penis that is not long and protected by a concave thoracic sternite 8. The thoracic sternite is not visible dorsally as in euryplacids. The taxonomic position of C. microphthalmus thus remains uncertain in anticipation of a revision of the Euryplacidae and related genera still in progress.</p> </div>	https://treatment.plazi.org/id/102B87CBFF8F2572FF34FA42FCA8FD11	Public Domain	No known copyright restrictions apply.

Depth: 397- 984 m.</p> <p>REMARKS</p> <p>Guinot (1969b: 526, as Pilumnoplax abyssicola) commented on the position of C. abyssicola, suggesting its position in Carcinoplax sensu lato rather than in the original conception of the genus (“ Carcinoplax sensu stricto ”). The species was included in Carcinoplax in a later revision, however (Guinot 1989).</p> <p>Carcinoplax abyssicola is only known from its male holotype, a small specimen collected from Fiji (cl 8.2 mm, cw 10.0 mm; BMNH 84.31). It is close to small specimens of C. specularis Rathbun, 1914, which has also been collected in Fiji (see Remarks of C. specularis below). The main difference between the two species is their outer orbital angles, flat and inclined posteriorly in C. abyssicola (Miers 1886: pl. 19, fig. 2; Guinot 1989: fig. 38, pl. 9, figs A, B) but typically raised as a conspicuous process in C. specularis (Guinot 1989: figs 24, as C. polita, 25; pl. 8, figs A, B). Guinot (1989: 307) considered C. verdensis Rathbun, 1914, a synonym of C. specularis (see Remarks for C. specularis below), as the species closest to C. abyssicola. Carcinoplax specularis is a highly variable species, however, and its outer orbital angle (Guinot 1989: fig. 22, as C. verdensis) can sometimes be as flat as that of C. abyssicola. Carcinoplax abyssicola and C. verdensis were correctly differentiated by the presence of more slen- der cheliped (P1) propodi in C. abyssicola (Guinot 1989: pl. 9, fig. C) in contrast to the conspicuously inflated ones of C. verdensis (and thus of C. specularis) (Guinot 1989: pl. 9, fig. F). The examination of the holotype of C. abyssicola also showed that its anterolateral teeth and ambulatory legs (P2-P5) are more slender than in C. specularis.</p> <p>There are doubts that Tesch’s specimens from Indonesia (Tesch 1918) actually belong to C. abyssicola. The specimens were collected by the Siboga Expedition but could not be found at ZMA, where all other Siboga goneplacids are deposited.</p> </div>	https://treatment.plazi.org/id/102B87CBFF912577FD59FA03FDD0FCB4	Public Domain	No known copyright restrictions apply.

Also characteristic is the presence of thick granules on the dorsal surface of the chelipeds (P1) and carapace, particularly the anterior and anterolateral margins. The granules, however, become less noticeable with size although they remain visible along the anterior margin.</p> <p>The morphology of the G1 also departs slightly from the typical G1 of Carcinoplax, the tip being elongated and slender (see Guinot 1989: fig. 29).</p> <p>The Vietnam material identified as C. confragosa by Zarenkov (1972: 241, fig. 7-1) clearly does not belong to this species. As previously noted by Guinot (1989: 91), there are clear differences between the three acute anterolateral teeth, which are directed outwards in the Vietnam specimen (shorter, blunt tip, directed anteriorly in C. confragosa), the slen- der and acute teeth of the P1 (shorter, blunt in C. confragosa), the complete front (with a median notch in C. confragosa), and the broad tip of the G1 of Zarenkov’s specimen (pointed and slender in C. confragosa). All of these characters are diagnostic of C. indica Doflein, 1904.</p> <p>A female from the South China Sea identified by Serène &amp; Lohavanijaya (1973: 67, figs 174, 175, pl. 16, fig. A) as C. confragosa does not belong to this species. It is perhaps an unidentified xanthid (Guinot 1989: 291).</p> </div>	https://treatment.plazi.org/id/102B87CBFF972577FF18FC59FC63FAF8	Public Domain	No known copyright restrictions apply.

Carapace convex, with 2 conspicuous, raised horizontal regions extending to lateral borders, anterior one across gastric region, posterior one across cardiac region; 2 spherical, slightly raised regions in central gastric portion of wide groove formed between horizontal ridges. Dorsal surface of carapace granular along anterior (hepatic region) and posterolateral borders; granules conspicuous along posterolateral borders. Front lamellar, straight, margin slightly convex, not marked by median notch. Slight notch between front, inner edge of supraorbital border. Supraorbital borders sinuous, margins smooth. Suborbital borders with large granules, each border with blunt inner tooth not visible dorsally. Large blunt to slightly pointed tooth on outer orbital angle; 2 anterolateral teeth on each side of carapace, first blunt, second curved, acute-tipped. Posterolateral borders arched.</p> <p>Subhepatic, pterygostomial regions, pterygostomial crest, pterygostomial lobe, merus, ischium of third maxilliped endopod with short, conspicuous granules.</p> <p>Eye peduncles (Fig. 3) short (0.2 front width), distal margin slightly granular, cornea slightly expanded distally.</p> <p>Chelipeds (P1) nearly equal in males, females, slightly more slender in males; fingers slender, as long as propodus, with cutting edges and broadly</p> <p>Castro P.</p> <p>blunt teeth, more than half of distal portion of fingers dark brown. Broad, curved, acute- to obtuse-tipped tooth on inner (ventral), proximal margin of carpus; smaller, curved, acute-tipped tooth on outer (dorsal), distal margin. Ambulatory legs (P2-P5) conspicuously long, slender, smooth; many short simple setae along inner, outer margins of P5 propodus, dactylus, outer margin of P5 carpus; P5 dactylus long, slender, smooth; length of P5 merus 0.6 cl.</p> <p>Male abdomen narrowly triangular, with 6 freelymovable somites plus telson; telson slightly wider than long, somite 3 covers space between P5 coxae. Somites 1, 2 slightly narrower than somite 3, thoracic sternite 8 not visible. G1 (Fig. 2A) long, slender; straight, slightly pointed tip. G2 (Fig. 2B) slender, nearly equal or slightly longer than G1, slightly curved flagellum, tip with spinule at each side.</p> <p>Female abdomen wide. Telson slightly wider than long. Somites 1, 2 cover space between P5 coxae, thoracic sternite 8 not visible. Vulva of mature females greatly expanded, extending from edge of slightly deflected suture 5/6 to suture 6/7; membrane covers aperture leaving space open along pointed anterior margin.</p> <p>Colour</p> <p>Carapace and chelipeds of recently preserved specimens with thick orange-red bands on a white to light orange-red background; ambulatory legs banded orange-red (see Ho et al. 2004: fig. 6G, as Carcinoplax inaequalis).</p> <p>REMARKS</p> <p>The examination of part of the type material of C. inaequalis (Yokoya, 1933) (see Remarks of the species below) showed that the Taiwan material identified as belonging to C. inaequalis species by Ho et al. (2004) as well as additional material from the Philippine Is and New Caledonia actually belong to a previously undescribed species.</p> <p>The new species shares many characters with C. inaequalis and C. specularis Rathbun, 1914: similar G1 and G2; conspicuous, rounded outer orbital angle; and acute second anterolateral tooth. The walking legs are noticeably longer and more slender in C. cracens n. sp. (Fig. 3) than in both C. inaequalis and C. specularis. The distal end of the merus of the folded P5 extends well beyond the tip of the second anterolateral tooth, but they extend to just the tip of the tooth in the other two species. The second anterolateral tooth is blunt in C. cracens n. sp. but acute in C. inaequalis and C. specularis. Also characteristic of the new species are the two conspicuous, carina-like horizontal ridges that extend across the carapace along the hepatic and gastric regions. Although not that conspicuous, the ridges may also be observed in C. inaequalis and in large specimens of C. specularis. The low tubercles on the hepatic region of the carapace are larger and hence more conspicuous in C. cracens n. sp. than in the other two species.</p> <p>A small (cl 5.2 mm, cw 6.3 mm), incomplete specimen (P1 and P2-P4 on one side only) from the Kai Is, Indonesia (MNHN-B 30056) is questionably identified as belonging to the new species.</p></div> 	https://treatment.plazi.org/id/102B87CBFF97257AFC9DFA82FDD0FD12	Public Domain	No known copyright restrictions apply.

Depth: 35- 384 m.</p> <p>REMARKS</p> <p>The species was not mentioned by Guinot (1989) in her revision of Carcinoplax but was commented upon in an earlier publication (Guinot 1969b: 526). The taxonomy of the species was discussed by Ho et al. (2004: 660) but their Taiwan material did not belong to C. inaequalis but to a species being described as new, C. cracens n. sp. (see above).</p> <p>The validity of C. inaequalis and its inclusion in Carcinoplax has been confirmed by the examination of five of the 20 syntype specimens listed in its description (Yokoya 1933: 194). The only male among the specimens examined is designated herein as the lectotype (KMNH IvR 100,002), and the four females as paralectotypes (KMNH IvR 100,004, 100,006). All characters agree with the description including the “two well-marked transversal carinae; the anterior on the gastric and another on the cardiac region”, which unfortunately are not indicated in the drawing accompanying the description (Yokoya 1933: 195, fig. 63). The anterolateral teeth are slender, with an acute tip, a character not clearly shown in Yokoya’s drawing. The ambulatory legs (P2-P5) are relatively short and thick, another character that distinguished C. inaequalis from C. cracens n. sp. (see Remarks for C. cracens n. sp. above).</p> <p>Carcinoplax inaequalis was placed in synonymy with Carcinoplax surugensis Rathbun, 1932 by Takeda &amp; Miyake (1969a). The material examined by them belonged indeed to C. surugensis as evidenced by their illustrations (Takeda &amp; Miyake 1969a: fig. 2) of the characteristic G1, G2, and male abdomen of this species (see Remarks for P. surugensis n. comb. and its inclusion in Pycnoplax n. gen. below). This is very puzzling since the authors (Takeda &amp; Miyake 1969a: 459) state that they examined dried specimens identified by Yokoya as Pilumnoplax inaequalis, including “some syntypes ”. The syntype selected as the lectotype (see above) was actually examined by Takeda as confirmed by the label “ Carcinoplax surugensis Rathbun, 1932 (June 1969, M. Takeda det.)” that was found together with the specimen. It seems that Takeda did not examine the G1 and G2 of the lectotype since the abdomen of the dried specimen was tightly closed. To add to the confusion, Sakai (1976: 540) erroneously referred to the P. surugensis n. comb. record of Takeda &amp; Miyake (1969a) as C. inaequalis (as Homoioplax haswelli), obviously unaware of the sharp differences in their respective G1 and G2.</p> <p>The G1 of the lectotype of C. inaequalis is typical of Carcinoplax (i.e. long, slender, and thin, being dorso-ventrally flattened). It has a pointed tip. The G2 (with flagellum that is shorter than the proximal portion) and narrow male abdomen are also characteristic of Carcinoplax. In Pycnoplax n. gen. the G1 is stout, thick, proximally broad, the G2 has a flagellum that is as short (as in P. surugensis n. comb.) or slightly shorter than the proximal portion, and the male abdomen is wider than in Carcinoplax (see Remarks for Pycnoplax n. gen. below).</p> <p>The material from Taiwan identified as C. inaequalis by Ho et al. (2004: 660) is characterized by long and slender ambulatory legs (P2-P5) and is being described as a new species (C. cracens n. sp.). Other differences and similarities between C. inaequalis and C. cracens n. sp. are given in the Remarks section of C. cracens n. sp. (above).</p> </div>	https://treatment.plazi.org/id/102B87CBFF9A257BFF17FCFBFE2FFB16	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Depth: 464- 800 m.</p> <p>REMARKS</p> <p>Carcinoplax ischurodous is unique among the species of Carcinoplax sensu stricto in having only one anterolateral tooth on each side of the rounded carapace. The outer orbital angle, however, is in the form of an acute, anteriorly-oriented tooth. A round carapace with small or no anterolateral teeth at all is restricted to large specimens of C. indica, C. longimana, C. monodi, and C. purpurea. Nevertheless, a relatively narrow male abdomen, slender and thin G1, greatly expanded vulva, and absence of a vulvar cover clearly establish the inclusion of C. ischurodous in Carcinoplax (see Manning &amp; Holthuis 1988). Guinot (1989: 314) included the species (as C. eurysternum) in a list of eight “non-revised” species of Carcinoplax in which only C. ischurodous proved not to belong to other genera.</p> </div>	https://treatment.plazi.org/id/102B87CBFF982579FF27FB24FF19FDB0	Public Domain	No known copyright restrictions apply.

Depth: 205- 820 m.</p> <p>REMARKS</p> <p>Examination of two specimens from southern India originally at the Indian Museum (female, cl 11.9 mm, cw 15.1 mm, pre-adult male, cl 8.5 mm, cw 11.4 mm; USNM 46291) allowed Guinot (1989: 303, fig. 26, pl. 10, figs A-C) to redescribe the species, but the description was based only on the female specimen. The second specimen, a pre-adult male, however, showed the most important characters outlined by Guinot for the female. It differed from the female in having only a slightly raised margin between the orbital margin and the first anterolateral tooth instead of a well defined rectangular tooth. The anterolateral teeth were thinner and more spiniform than those of the female. The G1 is thin and slender, the G2 slightly longer than the G1 and with two triangular spinules at the tip. The vulva of the female specimen was greatly enlarged, covered by a soft membrane except along the anterior margin, and occupying the whole breadth of thoracic sternite 6, all of which are characters shared by the species of Carcinoplax sensu stricto. The ambulatory legs (P2-P5) were long and relatively slender in both specimens so that the distal end of the merus of the folded P5 reached the tip of the second anterolateral tooth. The ambulatory legs of the female illustrated by Alcock &amp; Anderson (1895: pl. 14, fig. 7), however, are not as long as in the Indian Ocean specimens examined here. A photograph of a male from the Zoological Survey of India indicated as a cotype (Serène &amp; Lohavanijaya 1973: pl. 14, fig. D), however, shows the long and slender ambulatory legs characteristic of the species.</p> <p>Guinot (1989: 305) described a specimen from the Philippine Is (male, cl 18.2 mm, cw 25.0 mm; MNHN-B 10377) that showed some differences from the Indian Ocean specimens of C. longipes. It was listed separately as Carcinoplax aff. longipes (Guinot 1989: 305, figs 27, 35, pl. 10, figs D-F). The carapace of the Philippine Is specimen was found to be, as correctly pointed out by Guinot (1989), slightly less inflated than the Indian Ocean material of C. longipes, having a smooth dorsal surface (short tomentum in C. longipes), smooth chelipeds (P1) (distinct granules on the dorsal surface of the propodus and dactylus in C. longipes), and a distinct hook-like shape of the first anterolateral teeth (shorter, straighter in C. longipes). Another difference is that the P1-P5 appeared longer and thicker in the Philippine Is specimen than in C. longipes. The differences, however, were not measurable: P5 merus length 0.7 cl and P5 merus width 0.2 cl in both populations. Two additional specimens from the Philippine Is (♂, cl 15.2 mm, cw 21.2 mm, MNHN-B 10140; ♀, cl 12.3 mm, cw 17.6 mm, MNHN-B 11578) were found by Guinot (1989) to be intermediate between the Indian specimens and Carcinoplax aff. longipes. They were referred to as “ Carcinoplax sp. (aff. longipes)” (Guinot 1989: 305, pl. 10, fig. G). The dorsal surface of the carapace of both specimens had a short tomentum as in C. longipes but the second anterolateral teeth were more incurved as in C. aff. longipes. The most significant difference between the specimens from the Philippine Is and the two from the Indian Ocean that were examined is that the outer orbital angle was in the form of a distinct triangular tooth in the Philippine Is specimens, higher and therefore more conspicuous than in the Indian Ocean specimens. The examination of additional material from the Philippine Is has shown that the specimens previously identified by Guinot (1989) as Carcinoplax aff. longipes and Carcinoplax sp. (aff. longipes) be- long to C. longipes based on a comparison with the available Indian material.</p> <p>The records of C. longipes from Japan by Sakai (1969, 1976) remain questionable since no illustrations were given and his specimens could not be examined, but the photograph of Ikeda (1998: 135, pl. 55) of Japanese material confirms it as C. specularis Rathbun, 1914. The illustration of C. longipes by Chen (1984: fig. 6) shows that her specimen from the East China Sea most probably belongs instead to C. specularis.</p> </div>	https://treatment.plazi.org/id/102B87CBFF99257EFF2EFD5BFC11FDF0	Public Domain	No known copyright restrictions apply.

Depth: 36- 562 m.</p> <p>REMARKS</p> <p>As in C. longimana and a few other Carcinoplax species, the carapace of C. monodi is globose and the anterolateral teeth disappear with increased carapace size. The first anterolateral tooth, however, is not well developed even in small individuals (Guinot 1989: fig. 9A-C). The carapace shape and the size and shape of the anterolateral teeth are similar to those of C. purpurea Rathbun, 1914, with which it has been confused in the past. Diagnostic of C. purpurea, however, is a purple-red band along the carapace from the front to the posterior border (see Hsueh &amp; Huang 2002: fig. 8C). Carcinoplax purpurea is found in the western Pacific Ocean, whereas C. monodi lacks the purple-red band and is so far known only from the Red Sea. Unusual for a species of Carcinoplax is the large area of thoracic sternite 8 that is left exposed by the male abdomen (see Guinot 1969b: fig. 65; 1989: fig. 3).</p> <p>A relatively small female variously identified as C. purpurea Rathbun, 1914 (Balss 1929: 24), Carcinoplax sp. 2 (Türkay 1986: 162), and Carcinoplax sp. (aff. monodi) (Guinot 1989: fig. 10, pl. 3, figs I-K) most probably belongs to C. monodi, an identification that should be verified when additional material becomes available.</p> </div>	https://treatment.plazi.org/id/102B87CBFF9E257FFD4DFD9AFE3BFBD5	Public Domain	No known copyright restrictions apply.

The carapace, chelipeds (P1), and ambulatory legs (P2-P5) of the smaller specimens (to about cl 20-23 mm) were covered with conspicuous setae in contrast to the larger individuals, which lacked most or all of the setae. Conspicuous setae is also characteristic of C. spinosissima Rathbun, 1914, but C. nana can be distinguished from the latter by the presence of conspicuous but low, blunt tubercles on the dorsal surface of the cheliped propodi (see Guinot 1989: pl. 6, fig. H) (acute tubercles in C. spinosissima, although they may be absent in large individuals; see Chen 1998: fig. 4-2; Hsueh &amp; Huang 2002: fig. 5E), the dark portion of the fingers covers about half the total length of the fingers (dark portion is about one quarter of fingers in C. spinosissima), and the smooth distal portion of the meri of the ambulatory legs (an acute tooth in C. spinosissima; see Chen 1998: fig. 4-2; Hsueh &amp; Huang 2002: fig. 5C).</p> <p>Material identified as C. nana by Ho et al.

It can also be confirmed that part of the MUSORSTOM 1 material originally identified as C. purpurea by Serène &amp; Vadon (1981) actually belonged to C. sinica as previously reported by Guinot (1989: 287).</p> </div>	https://treatment.plazi.org/id/102B87CBFF9D257DFF6CFE9FFC63FD12	Public Domain	No known copyright restrictions apply.

Depth: 174- 850 m. Specimens were also obtained from tangle nets of local fishermen in the Philippines that obtained material from at least 50 m. COLOUR</p> <p>A photograph of a freshly-collected female specimen from the Solomon Is (MNHN-B 29394) showed a red carapace and chelipeds and ambulatory legs banded with red. Photographs of freshly-collected material from the Philippine Is (PANGLAO 2005) showed carapaces coloured with various hues of red. A large female from the Philippine Is (cl 24.4 mm, cw 32.2 mm; ZRC 2006.0217), however, had irregular orange-red lines on the carapace and right cheliped. The specimen shown by Ikeda (1998: 135, pl. 55, as C. longipes) is similarly red. Hints of the red colour were observed in a few large preserved specimens.</p> <p>REMARKS</p> <p>Carcinoplax specularis was described, but not illustrated, from a large male (cl 16.7 mm, cw 23.0 mm, USNM 46164) by Rathbun (1914). The description is relatively short and ambiguous, and most of the discussion dealt with differences between C. specularis and C. longipes (Wood-Mason, 1891). Sakai (1969: fig. 15c) illustrated the holotype but his drawing is small and not very accurate. Guinot (1989: fig. 25, pl. 8, figs A-D), however, provided clear line drawings and photographs of the holotype. The dorsal margin of the right outer orbital angle of the holotype seems to have been detached after Guinot’s photograph was taken; the extreme right margin of the front is similarly detached but remains attached to the carapace.</p> <p>Carcinoplax verdensis Rathbun, 1914 was described at the same time as C. specularis from only a female (cl 10.5 mm, cw 13.0 mm, USNM 46167) much smaller than the holotype of C. specularis. Rathbun’s description does not include any illustrations and, as in the description of C. specularis, the short description consists of a comparison with C. longipes. It is surprising that Rathbun did not compare C. verdensis with C. specularis, even if both species were described using specimens collected by the Albatross from localities close to each other in the Philippine Is. Sakai (1969: fig. 15d) and Guinot (1989: fig. 22, pl. 9, figs D-F) illustrated the holotype of C. verdensis. As in the case of the holotype of C. specularis, Sakai’s line drawing is small and inaccurate. A third species, C. polita Guinot, 1989, was described from three small Philippine specimens previously identified as C. specularis by Serène &amp; Vadon (1981).</p> <p>Examination of the holotypes of C. specularis and C. verdensis shows some clear differences. These differences, as well as similarities in the general shape of the carapace, were outlined by Guinot (1989: 301) when the holotypes were compared by her. The outer orbital angle of the holotype of C. specularis is prominent, tooth-like (see Guinot 1989: fig. 25, pl. 8, figs A, B) in contrast to almost straight, lacking a tooth or a lobe, in the holotype of C. verdensis (see Guinot 1989: fig. 22, pl. 9, figs D, E). The anterolateral teeth of C. specularis are also prominent and anteriorly curved, whereas those of C. verdensis are shorter and not as prominent. The dorsal surface of the carapace, chelipeds (P1), and the ambulatory legs (P2-P5) of the holotype of C. verdensis have a short, barely discernible tomentum that is absent in the holotype of C. specularis. Both holotypes, however, have a short tomentum on the ventral surface of the carapace and abdomen. Other differences not pointed out by Guinot are the presence of a blunt tooth on the dorsal surface of the cheliped merus of the holotype of C. specularis that is barely discernible in the holotype of C. verdensis, and visibly thicker ambulatory legs in the holotype of C. specularis (P5 merus width to length ratio of 0.23) than in the holotype of C. verdensis (P5 merus width to length ratio of 0.19). Two other characters were also mentioned by Guinot, the extent of the dark coloration of the cheliped fingers and the texture of the cheliped merus (see below).</p> <p>Carcinoplax polita was described on account of several characters that were different from those of C. specularis (Guinot 1989: 300, figs 24, 37, pl. 8, figs E-H): outer orbital teeth more salient and anterolateral teeth more curved and pointed than in C. specularis, granules on the hepatic region that are more apparent in C. specularis, a small spine on the antero-external angle of the cheliped carpus that is absent in C. specularis, a rounded and glabrous portion on the distal portion of the cheliped carpus in contrast to a flatter and oval surface in C. specularis, dark fingers in contrast to colourless fingers in C. specularis, tip of G1 with a shorter and inflated tip in C. specularis, and distal part of G2 straight rather than curved as in C. specularis. Guinot (1989: 301) also contrasted C. polita with C. verdensis by referring to differences in the shape of the anterolateral teeth, the shiny portion on the cheliped diagnostic of C. polita, and the coloration of the cheliped fingers.</p> <p>Confusion between C. specularis and C. verdensis already existed before the examination of the respective holotypes by Guinot (1989). Serène &amp; Vadon (1981: 126) reported on the presence of both C. specularis and C. verdensis from the South China Sea, but their only specimen of C. verdensis, a male, was identified as such with “reservations”. The same specimens identified as C. specularis by Serène &amp; Vadon were the ones used by Guinot in her description of C. polita.</p> <p>Although there are differences between the holotypes, particularly those of C. specularis and C. verdensis, examination of a large number of specimens (more than 250) from the Maldive Is as well as from the western Pacific Ocean from Taiwan to Tonga showed that these and other potential species-specific differences (morphologies of the abdomen, G1, G2, and vulva) were not constant when applied to a large number of specimens. Specimens sampled ranged from small pre-adults to large adults (largest male cl 24.0 mm, cw 32.0 mm [ZRC 2001.0973], largest female cl 19.4 mm, cw 23.8 mm [MNHN- B 29380]). Many specimens, particularly those of a size intermediate between the large holotype of C. specularis (cl 16.7 mm, cw 23.0 mm) and the smaller holotype of C. verdensis (cl 10.5 mm, cw 13.0 mm) had outer orbital angles and anterolateral teeth with a variable morphology and intermediate width of the P5 meri. The short tomentum, which is present in the holotype of C. verdensis but absent in that of C. specularis, is clearly a variable character. Some specimens had a tomentum while others of the same sex and about the same size lacked it even if collected from the same station. The assumed differences between the three species are due to size and therefore are not species-specific. The three species, C. specularis, C. verdensis, and C. polita, are therefore considered herein as conspecific. Carcinoplax specularis Rathbun, 1914 has been chosen as the name of the species since it appears first in Rathbun (1914) and its male holotype best represents the characters of the species. Carcinoplax verdensis Rathbun, 1914, and C. polita Guinot, 1989, are therefore junior subjective synonyms of C. specularis.</p> <p>There are also close similarities between C. specularis and C. abyssicola (Miers, 1886), a species reliably known only from the holotype specimen from Fiji (see Remarks for C. abyssicola above), where C. specularis has been collected. The taxonomy of C. specularis may be further complicated if both are shown to be conspecific and C. specularis becomes a junior synonym of C. abyssicola.</p> <p>The G1 (see Guinot 1989: fig. 34A, G1 of holotype) is typical of that of other species of Carcinoplax, being long, slender, thin, and with a truncated, interiorly rounded, exteriorly pointed tip. The G2 (see Guinot 1989: fig. 34B, G2 of holotype) is slightly shorter than the G1. It has a slightly curved flagellum that ends in a slightly expanded tip with two terminal spinules. Somite 2 of the male abdomen is slightly narrower than somite 3, thoracic sternite 8 not visible. The vulva of the mature females is also typical of Carcinoplax, being greatly expanded, extending from suture 5/6 to suture 6/7, and covered by a soft membrane.</p> </div>	https://treatment.plazi.org/id/102B87CBFF9D2541FD60FCFBFC51FC15	Public Domain	No known copyright restrictions apply.

The ambulatory legs were orange with irregular white spots.</p> <p>REMARKS</p> <p>Diagnostic of C. spinosissima are the conspicuous setae on the carapace, chelipeds (P1), and ambulatory legs (P2-P5). Large specimens lack the setae and sometimes the characteristic acute tubercles on the dorsal surface of the cheliped meri (Guinot 1989: pl. 7, figs F, H). Also diagnostic is the presence of a tooth on the distal, dorsal margins of the ambulatory leg (P2-P5) meri, which Rathbun (1914) did not mention in her description of the species. Some specimens, however, may lack a tooth on one or more of the legs but the tooth is always present on the other member of the pair. The tooth is clearly shown by Hsueh &amp; Huang (2002: fig. 5C). Differences between C. spinosissima and C. nana, which also has conspicuous setae, are outlined in the Remarks section for the latter (see above).</p> </div>	https://treatment.plazi.org/id/102B87CBFFA12546FD6EFBE6FDBAF97B	Public Domain	No known copyright restrictions apply.

Depth: 135- 720 m.</p> <p>DESCRIPTION</p> <p>Carapace (Figs 4A; 5) quadrate, slightly wider than long (1.2 as wide as long in holotype), anterolateral borders arched, inflated, giving carapace globose appearance. Carapace convex, without clear indication of regions. Front lamellar, straight, not marked by median notch. Slight notch between front, inner edge of supraorbital border. Supraorbital borders sinuous, margins granular. Suborbital borders granular, each with short, blunt inner tooth not visible dorsally. No tooth on outer orbital angle other than the curved, granular border of the orbit; 2 slender, spinous, acute-tipped anterolateral teeth on each side of carapace. Posterolateral borders arched.</p> <p>Subhepatic, pterygostomial regions, pterygostomial crest, pterygostomial lobe, merus, ischium of third maxilliped endopod with short, conspicuous granules.</p> <p>Eye peduncles (Figs 4A; 5) short (0.2 front width), distal margin granular, cornea slightly expanded distally.</p> <p>Chelipeds (P1) (Fig. 5) nearly equal in males, females, slightly more slender in males; fingers</p> <p>Revision of Goneplacinae (Crustacea, Brachyura)</p> <p>slender, as long as propodus in males, much shorter in females, with blunt teeth, less than half of distal portion of fingers dark brown. Broad, curved, acute-tipped tooth on inner (ventral), proximal margin of carpus, smaller tooth on outer (dorsal), distal margin. Ambulatory legs (P2-P5) moderately long, slender, smooth; many long simple setae along inner, outer margins of P5 propodus, dactylus, outer margin of P5 carpus, shorter along P2-P4, some long simple setae along P2-P4 meri, carpi, propodi; P5 dactylus long, slender, smooth; length of P5 merus 0.5-0.6 cl.</p> <p>Male abdomen (Fig. 4B) narrowly triangular, with 6 freely-movable somites plus telson; telson slightly wider than long, somite 3 covers space between P5 coxae. Somites 1, 2 slightly narrower than somite 3, small portion of thoracic sternite 8 visible. G1 (Fig. 4C) long, slender, straight; pointed tip with scattered spinules. G2 (Fig. 4D) slender, nearly equal or slightly longer than G1, slightly curved flagellum, tip with 2 lateral spinules.</p> <p>Female abdomen wide. Telson slightly wider than long. Somites 1, 2 cover space between P5 coxae, thoracic sternite 8 not visible. Vulva of mature females greatly expanded, extending from edge of slightly deflected suture 5/6 to suture 6/7; membrane covers aperture leaving space open along anterior margin.</p> <p>Colour</p> <p>The holotype specimen (MNHN-B 29496) was photographed soon after collection. The carapace was orange and the ambulatory legs transparent and banded with orange.</p> <p>REMARKS</p> <p>The overall morphology of the new species is remarkably similar, almost identical, to that of Pycnoplax bispinosa (Rathbun, 1914) n. comb. Both species have two relatively short, slender, and acute anterolateral teeth (Figs 4A; 5 for C. tenuidentata n. sp.; Fig. 13B for P. bispinosa n. comb.). The teeth are seemingly dorsal, just at the border of a conspicuously inflated section of the carapace. The legs are slightly longer and more slender (distal end of the merus of the folded P5 reaches the proximal portion of the second anterolateral teeth in both species but not in the largest specimens of P. bispinosa n. comb.). There are also short setae on the ventral surface of the carapace, third maxilliped, abdomen, and ambulatory legs (P2-P5).</p> <p>The most obvious difference between the new species and P. bispinosa n. comb. is in the pterygostomial region on the ventral surface of the carapace. In C. tenuidentata n. sp. the pterygostomial and subhepatic regions are about the same relative height. In contrast, in P. bispinosa n. comb. the pterygostomial region is much higher than the subhepatic region and the two regions are separated from each other by a conspicuous pterygostomial ridge. Other differences are listed in the Remarks section for P. bispinosa n. comb. (see below).</p> <p>Unusual for a species of Carcinoplax is that the orbital border does not continue into a lobe or tooth. It ends as a rounded and granular border well above the first anterolateral tooth (Fig. 4A).</p> </div>	https://treatment.plazi.org/id/102B87CBFFA62545FCBCFF3EFDE5FC93	Public Domain	No known copyright restrictions apply.

The G2 of specimens examined during this study was actually slightly longer than the G1, raising the possibility that the specimens referred to by Serène &amp; Lohavanijaya (1973) belonged to another, yet unidentified, species. The Philippine material identified by Serène &amp; Vadon (1981) as C. aff. tomentosa also appears to be lost.</p> </div>	https://treatment.plazi.org/id/102B87CBFFA52545FF02FC79FBA9FAD8	Public Domain	No known copyright restrictions apply.

Carapace slightly convex, slightly granular along anterior, lateral borders (conspicuously granular in ovigerous female paratype), with short setae, without clear indication of regions. Front lamellar, straight, not marked by median notch. Notch between front, inner edge of supraorbital border. Supraorbital borders sinuous, margins granular in holotype and most other specimens. Suborbital borders granular, each with short, blunt inner tooth not visible dorsally. Outer orbital angle with flat, granular, short tooth; 2 dorso-ventrally flat, triangular, granular, blunttipped anterolateral teeth on each side of carapace, margin between anterolateral teeth nearly straight. Posterolateral borders slightly arched.</p> <p>Subhepatic, pterygostomial regions, merus, ischium of third maxilliped endopod with low, conspicuous granules. Margins of thoracic sternum with short setae.</p> <p>Eye peduncles (Figs 6A; 7) short (0.2 front width), distal margin granular, cornea short, not expanded distally.</p> <p>Chelipeds (P1) (Figs 7; 8) nearly equal in males, females, slightly more slender in females; fingers short, thick, about a third as long as propodus in both sexes, with blunt teeth, all or nearly all distal portion of fingers dark brown. Propodus, carpus, merus fringed with sparse, long setae (few in holotype); propodus short, thick; conspicuous, blunt or slightly acute tubercles on outer (dorsal) surface of propodus (may be only on proximal region in one of two propodi), outer (dorsal) anterior border of carpus; shorter, less conspicuous granules on inner (ventral) surface of merus, inner margin granular. Ambulatory legs (P2-P5) relatively short (distal end of merus of the folded P5 only reaches tip of second anterolateral tooth), relatively stout articles, smooth, many short and long simple setae along inner, outer margins of articles; P5 dactylus long, slender, setose; length of P5 merus 0.7 cl.</p> <p>Male abdomen (Fig. 6B) narrowly triangular, with 6 freely-movable somites plus telson; telson wider than long. Somite 3 covers space between P5 coxae. Somites 1, 2 slightly narrower than somite 3, thoracic sternite 8 not visible. G1 (Fig. 6C) long, slender, straight; rounded tip with slightly pointed inner margin. G2 (Fig. 6D) slender, slightly longer than G1, slightly curved flagellum, tip with 2 terminal spinules.</p> <p>Female abdomen narrow, fringed with many long setae. Telson slightly wider than long. Somites 1, 2 cover space between P5 coxae, thoracic sternite 8 not visible. Vulva of mature females greatly expanded, extending from edge of slightly deflected suture 5/6 to suture 6/7; membrane covers aperture leaving space open along anterior margin.</p> <p>REMARKS</p> <p>Carcinoplax tuberosa n. sp. is close to C. velutina n. sp. (see description below). Both species share a short tomentum on the carapace, a more conspicuous tomentum on the ambulatory legs (P2-P5), granular ventral surface of the carapace, short and thick fingers, short eye peduncles, and cornea relatively short and not expanded distally. Carcinoplax tuberosa n. sp. is being described as a separate species on account of several differences. The G1 has a broadly rounded tip (Fig. 6C) whereas it is pointed in C. velutina n. sp. (Fig. 9C). The ambulatory legs of C. tuberosa n. sp. are shorter and slightly narrower than in C. velutina n. sp. (Fig. 10). In C. tuberosa n. sp. the distal end of the merus in the folded P5 reaches the tip of the second anterolateral tooth, whereas in C. velutina n. sp. they extend well over the tooth (almost reaching the tip of the first anterolateral tooth in the holotype). The setae on the ambulatory legs of C. tuberosa n. sp. are also conspicuously longer and more numerous than in C. velutina n. sp. An exception is a pre-adult male from the Philippine Is (ZRC 2006.0172), where the setae are short. The propodi and carpi of the chelipeds (P1) have conspicuous tubercles in C. tuberosa n. sp. (Fig. 8), which are absent in C. velutina n. sp. of about the same size.</p> <p>Carcinoplax tuberosa n. sp. appears to be a smallsize species, the largest male being cl 7.0 mm, cw 9.0 mm (MNHN-B 29829) and the largest female, which was ovigerous, cl 6.9 mm, cw 8.8 mm (MNHN-B 29833). A small female (cl 5.8 mm, cw 6.8 mm; MNHN-B 29830) had an enlarged vulva, evidence that it was mature. The damaged specimen of a pre-adult male from the Philippine Is (cl 2.5 mm, cw 2.9 mm; ZRC 2006.0172) shares all of the diagnostic characters of the type material except the long setae of its ambulatory legs. The new species thus appears not to be pre-adult specimens of C. velutina n. sp. Carcinoplax velutina n. sp., however, is known mostly from relatively large specimens (smallest: female, cl 9.7 mm, cw 12.5 mm; MNHN-B 29828).</p> </div>	https://treatment.plazi.org/id/102B87CBFFA52549FCA4FAA5FE50FE8E	Public Domain	No known copyright restrictions apply.

Depth: 300- 680 m.</p> <p>DESCRIPTION</p> <p>Carapace (Figs 9A; 10; Poupin 1996b: pl. 16, fig. d, as Carcinoplax aff. verdensis) quadrate, slightly wider than long (1.3 as wide as long in holotype). Carapace slightly convex, granular along anterior, lateral borders, with short setae on posterior half, without clear indication of regions.Front lamellar, margin granular, straight, not marked by median notch. Notch between front, inner edge of supraorbital border. Supraorbital borders sinuous, margins granular, slight prominence before outer orbital angle.Suborbital borders granular, each with short, blunt inner tooth not visible dorsally. Outer orbital angle with flat, granular, blunt tooth; 2 dorso-ventrally flat, triangular, granular, blunttipped anterolateral teeth on each side of carapace, margin between anterolateral teeth nearly straight. Posterolateral borders arched.</p> <p>Subhepatic, pterygostomial regions, pterygostomial lobe, merus, ischium of third maxilliped endopod with short, conspicuous granules. Margins of thoracic sternum with short setae.</p> <p>Eye peduncles (Figs 9A; 10) short (0.2 front width), distal margin granular, cornea short, not expanded distally.</p> <p>Chelipeds (P1) (Fig. 10; Poupin 1996b: pl. 16, fig. d, as Carcinoplax aff. verdensis) nearly equal in males, females, slightly more slender in females; fingers slender, as long as propodus in males, slightly longer than propodus in females, with blunt teeth, 3/4 or nearly all distal portion of fingers dark brown. Broad tooth on inner (ventral), proximal margin of carpus, acute-tipped in some specimens, inner margin granular in holotype. Ambulatory legs (P2- P5) long (distal end of the merus of the folded P5 reaches well beyond tip of second anterolateral tooth, in holotype almost reaching tip of first anterolateral tooth), relatively stout articles, granular, many short and long simple setae along inner, outer margins of articles; P5 dactylus long, slender, setose; length of P5 merus 0.7-0.8 cl.</p> <p>Male abdomen (Fig. 9B) broadly triangular, fringed by short setae, with 6 freely-movable somites plus telson; telson slightly wider than long. Somite 3 covers space between P5 coxae; somites 1, 2 only slightly narrower than somite 3, thoracic sternite 8 not visible. G1 (Fig. 9C) long, slender, straight; pointed tip. G2 (Fig. 9D) slender, slightly longer than G1, slightly curved flagellum, tip with 2 terminal spinules.</p> <p>Female abdomen narrow, fringed with many long setae. Telson wider than long. Somites 1, 2 cover space between P5 coxae, thoracic sternite 8 not visible. Vulva of mature females greatly expanded, extending from edge of slightly deflected suture 5/6 to suture 6/7; membrane covers aperture leaving space open along anterior margin.</p> <p>COLOUR</p> <p>Carapace light orange; chelipeds (P1) mostly light orange, tips of fingers dark brown (Poupin 1996b: pl. 16, fig. d, as Carcinoplax aff. verdensis).</p> <p>REMARKS</p> <p>Carcinoplax velutina n. sp. is easily separated from other species of Carcinoplax by its long ambulatory legs (P2-P5), the distal end of the merus of the P5 reaching the second anterolateral tooth; the short tomentum on the legs and on the margins of the abdomen (longer setae on the female abdomen) and thoracic sternum; the short setae on the posterior half of the carapace; and the nearly flat outer orbital teeth.</p> <p>It is particularly close to C. tuberosa n. sp. Similarities and differences between the two species are discussed in the description of the latter (see above). There are also some similarities with C. abyssicola, described from Fiji, and C. specularis, with a wider geographical distribution but also known from Fiji, which have a short tomentum on the carapace and</p> <p>Castro P.</p> <p>ambulatory legs and the legs have relatively stout articles. In C. abyssicola, however, the outer orbital tooth is greatly reduced so that the carapace margin beyond the orbit is typically slanted, not straight, and the anterolateral teeth are curved and more salient than in C. velutina n. sp. (see Guinot 1989: fig. 38, pl. 9, figs A, B) and the eyes are clearly larger than in C. velutina n. sp., where the cornea is not much enlarged distally.</p> <p>Carcinoplax velutina n. sp. somewhat resembles C. longipes from the Indian Ocean and the Philippine Is in the shape of the outer orbital tooth and in the long ambulatory legs. C. longipes, however, has a curved first anterolateral tooth (Guinot 1989: fig. 26, pl. 10, figs A, B; fig. 27, pl. 10, figs D, E, as Carcinoplax aff. longipes; pl. 10, fig. G, as Carcinoplax sp.) and a much sparse tomentum on the carapace and ambulatory legs.</p> <p>A small male from Fiji (cl 8.0 mm, cw 10.1 mm; MNHN-B 29834) had the same carapace shape and anterolateral teeth and the same relative length of the ambulatory legs as in C. velutina n. sp. but the setae of the ambulatory legs (P2-P5) were longer and more conspicuous than in C. tuberosa n. sp.</p></div> 	https://treatment.plazi.org/id/102B87CBFFA9254FFF56FE7CFB4DFBB6	Public Domain	No known copyright restrictions apply.

Notch between front, inner edge of supraorbital border slight; orbits long, wide, expanded distally; supraorbital borders bilobed, with conspicuous tubercle-like process; suborbital borders long, rounded, without inner tooth; anterolateral borders convex. Dorsal surface of carapace covered by abundant setae, moderately convex, without clear indication of regions. Outer orbital angle with short prominence; 2 short anterolateral teeth on each side of carapace. Basal antennal article short, subquadrate, distalmost (third) article reaches front. Eye peduncles (Shen 1932: fig. 64, as C. vestita) relatively long (0.5 front width), dorsal surface with conspicuous setae; cornea reniform, dorso-ventrally flattened, much expanded distally, nearly divided into anterior, posterior portions. Anterior border of endostome well demarcated from buccal cavern, ridges clearly defined. Third maxillipeds completely close the buccal cavern. No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Sulcus on thoracic sternite 4 conspicuous but interrupted medially (Fig. 11); sutures 4/5, 5/6, 6/7, 7/8 interrupted medially. Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers (Shen 1932: fig. 65a; Sakai 1976: pl. 190, fig. 3, as C. vestita) slender, nearly triangular, shorter than propodus, tips light in colour; large, blunt teeth. Carpus with tooth on inner margin. Dorsal margins of meri, carpi, propodi of ambulatory legs (P2-P5) unarmed, covered with setae; dactyli slender, smooth, numerous thick setae. Male abdomen (Shen 1932: fig. 65b, as C. vestita) with 6 freely-movable somites plus telson, narrowly triangular; somite 1 long (longest somite), wide; somites 4-6 gradually decreasing in width from somite 3 (widest somite). Telson wider than long. Somite 3 covers space between P5 coxae, somite 2 narrower than somite 3 so that somite 2 leaves relatively large portion of thoracic sternite 8 visible. G1 (Takeda &amp; Miyake 1968: fig. 5f; Dai &amp; Yang 1991: fig. 192-2, as C. vestita) long, slender, thin, straight, only slightly broadened proximally; pointed, thin tip. G2 (Takeda &amp; Miyake 1968: fig. 5g, as C. vestita) slender, slightly longer than G1, flagellum slightly shorter than proximal part (peduncle), slightly-expanded tip with lateral spinule. Penis arising from P5 coxa, moderate size; slightly-expanded, soft proximal expansion. Female abdomen (Shen 1932: fig. 65c, as C. vestita) with 6 freely-movable somites, wide.Telson wider than long. Somite 1 long, wide; somite 2 covers space between P5 coxae, thoracic sternite 8 not visible. Vulva of mature females (Fig. 11; Doi &amp; Watanabe 2006: fig. 1) greatly expanded, extending from suture 5/6 to suture 6/7, covered by soft membrane, thickened inner margins but vulvar cover absent.</p> <p>REMARKS</p> <p>The new genus is being described for Carcinoplax vestita, which was described as Cancer (Curtonotus) vestitus de Haan, 1833. Guinot (1989: 314) listed the species among eight non-revised species of Carcinoplax that eventually proved to belong in other genera.</p> <p>Diagnostic of Entricoplax n. gen. is a supraorbital border that is long and bilobed, with orbits expanded to accommodate the reniform eyes (in contrast to Carcinoplax, where the supraorbital bor- der is curved or sinuous, with orbit not expanded and distal portion of the cornea is rounded), a concave, conspicuously deflexed front (straight in Carcinoplax), suborbital border long and without an inner tooth (shorter and with a short inner tooth in Carcinoplax), somite 1 of male and female abdomens conspicuously long, much longer than somite 2 in both sexes and longer than somite 3 in the male abdomen (short in Carcinoplax), and large area of thoracic sternite 8 of males is left uncovered (usually completely or partially covered by somite 2 in Carcinoplax), basal antennal article short and subquadrate (slender and longer in Carcinoplax), and short anterolateral teeth (longer and more conspicuous in most species of Carcinoplax). Also characteristic of E. vestita n. comb., the only species included in the new genus, is the relatively long and dense setae that cover the carapace and pereopods.</p> <p>The G1, G2, and vulva of Entricoplax n. gen. are nevertheless similar to those of Carcinoplax. The G1 is slender, straight, and thin, being close to that of C. longimana, the type species of the genus (see Takeda &amp; Miyake 1968: fig. 5; Dai &amp; Yang 1991: fig. 192-2, as C. vestita; Kim 1973: fig. 162B, as C. vestitus). The G2 is slightly longer than the G1, shorter than the proximal part (peduncle), and has a slightly-expanded tip with one lateral spinule, similar to the G2 of some species of Carcinoplax. The vulva (Fig. 11) is expanded and lacks a vulvar cover as in Carcinoplax.</p> <p>Entricoplax vestita (de Haan, 1833) n. comb.

(see above). Entricoplax vestita n. comb. appears to be restricted to the Yellow and East China seas and the Pacific Ocean coast of Japan. A record from South Africa is the result of a misidentification (see Barnard 1950: 288, as C. vestita). It has also been listed, almost certainly as an error or oversight, as occurring in Australia (Balss 1922: 136; Barnard 1950: 288; Sakai 1976: 525; Davie 2002: 194, as C. vestita).</p> <p>Two small pre-adult females (cl 6.3 mm, cw 8.9 mm, cl 8.7 mm, cw 12.2 mm, BMNH) from Japan identified as Pilumnoplax vestita var. sexdentata by Miers (1886: 229) clearly belong to E. vestita n. comb., the only difference being that their anterolateral teeth are more pronounced than those of adult individuals.</p> </div>	https://treatment.plazi.org/id/102B87CBFFAF2552FC9BFB47FC99FA98	Public Domain	No known copyright restrictions apply.

G2 (Chen 1984: figs 7-7 to 7-9, as C. longispinosa; Guinot 1989: fig. 32B, as C. longispinosa) slender, much shorter than G1, flagellum much shorter than basal part, with basal denticles, tip pointed. Penis arising from P5 coxa, large; broad, soft proximal expansion.Female abdomen with 6 freely-movable somites, relatively narrow. Telson broadly triangular, wider than long. Somite 3 covers space between P5 coxae, somite 2 as wide as somite 3, thoracic sternite 8 not visible. Vulva of mature females (Fig. 12) oblique, crescent shaped, extending from suture 5/6 to suture 6/7, vulvar cover in the form of swollen section of thoracic sternite 6 covering outer margin.</p> <p>REMARKS</p> <p>Menoplax n. gen. is being described as a monotypic genus for Carcinoplax longispinosa Chen, 1984. In contrast to Carcinoplax, the new genus is characterized by a stout, truncated G1 with an acuminate tip (slender, thin, with a typically rounded tip in Carcinoplax), a G2 that is much shorter than the G1 (typically as long as the G1, never much shorter as in Carcinoplax), the presence of a crescent shaped vulva provided with a vulvar cover (Fig. 12) (vulva greatly enlarged and without a vulvar cover in Carcinoplax), a female abdomen narrower than that of Carcinoplax, a complete 6/7 suture (incomplete in Carcinoplax), conspicuously slender and long fingers, carinated dactyli of ambulatory legs (smooth in Carcinoplax), slender basal antennal article that is longer than that in Carcinoplax, and a strongly convex carapace armed with long second anterolateral teeth unlike any species of Carcinoplax.

The first anterolateral tooth is reduced in females (see Guinot 1989: pl. 13, figs D, E, as Carcinoplax longispinosa), while the conspicuous, acute second tooth tends to be slightly shorter than that in males (see Guinot 1989: fig. 40, pl. 13, figs A, B, as C. longispinosa). The length and orientation of the second, horn-like tooth, however, varies among individuals of both sexes, even between the right and left teeth in some specimens.</p> <p>The morphology of two small females (MNHN- B 10207, 10208) from Madagascar, also examined by Guinot (1989: 312), does not depart from other specimens collected elsewhere in the Indo-West Pacific region. The species has not yet been recorded from elsewhere in the Indian Ocean but it is most probably found in deep water across the ocean.</p> <p>There is a superficial resemblance between the carapaces of M. longispinosa n. comb. and C. ischurodous (Stebbing, 1923). Carcinoplax ischurodous has a long anterolateral tooth somewhat similar to the second anterolateral tooth of M. longispinosa n. comb. There is only one anterolateral tooth in C. ischurodous, however, and its G1, G2, and vulva are characteristic of Carcinoplax: slender G1, G2 with long flagellum (see Guinot &amp; Richer de Forges 1981b: fig. 10A-D), and an enlarged, oval vulva covered by a soft membrane.</p> </div>	https://treatment.plazi.org/id/102B87CBFFB22556FC92FA65FEA8FE30	Public Domain	No known copyright restrictions apply.

G, as Carcinoplax meridionalis, and pl. 12, fig. F, as C. victoriensis) transversely quadrate, slightly wider than long, widest at junction of anterolateral, posterolateral borders; front lamellar, straight, not marked by median notch or projection. Notch between front, inner edge of supraorbital border (absent or barely discernible in P. bispinosa n. comb.); orbits narrow, not expanded distally; supraorbital borders slightly sinuous; suborbital borders rounded, with short, blunt inner tooth not visible dorsally; anterolateral borders convex; posterolateral borders long, arched. Dorsal surface of carapace smooth (2 slight horizontal ridges across carapace in P.victoriensis n. comb.; Guinot 1989: pl. 12, fig. F, as Carcinoplax victoriensis) strongly convex, without clear indication of regions. Outer orbital angle with short, triangular tooth (absent in P. bispinosa n. comb., see Fig. 13B); 2 anterolateral teeth on each side of carapace. Basal antennal article short, thick, distalmost (third) article reaches front. Eye peduncles (Figs 13A, B; 16A; 17) short, much shorter than front (0.2 front width); cornea spherical, only slightly expanded distally. Anterior border of endostome well demarcated from buccal cavern, ridges faint but clearly defined. Third maxillipeds completely close the buccal cavern. No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete (Figs 14; 15; 18). Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers moderately slender, shorter than propodus (longer in P. latifolia n. sp.), tips darker in colour (except P. victoriensis n. comb.; Poore 2004: pl. 24, fig. b). Carpus with tooth on inner margin. Dorsal margins of meri, carpi, propodi of ambulatory legs (P2-P5) unarmed; dactyli slender, smooth, setose. Male abdomen with 6 freely-movable somites plus telson, relatively wide, somites 4-6 gradually decreasing in length from somite 3 (widest somite). Telson wider than long. Somite 3 covers space between P5 coxae, somite 2 slightly narrower than or as wide as somite 3 so that thoracic sternite 8 not visible or only leaving small portion visible (in P. bispinosa n. comb. and P. meridionalis n. comb.). G1 (Fig. 16C; Zarenkov 1972: fig. 6-2; Serène &amp; Lohavanijaya 1973: figs 158-162; Chen 1984: figs 4-5, 4-6; Guinot 1989: fig. 30A, as Carcinoplax bispinosa; Guinot 1969b: fig. 73; 1989: fig.31A; Chen 1984: figs 3-5, 3-6; Dai &amp; Yang 1991: fig. 192-1, as C. surugensis) stout, thick, proximally broad, diagonally oriented or straight with bent distal portion, with small spinules, pointed tip. G2 slender, slightly longer or noticeably longer than G1, typically dark brown, flagellum shorter or almost as long as proximal part (peduncle); tip pointed (P. surugensis n. comb.), pointed with several spinules (P. meridionalis n. comb.), slightly-expanded with 2 terminal spinules (P. bispinosa n. comb., P. latifolia n. sp., P. victoriensis n. comb.). Penis arising from P5 coxa, moderate size; broad, soft proximal expansion. Female abdomen with 6 freely-movable somites, wide. Telson wider than long. Somite 3 covers space between P5 coxae, somite 2 narrower than somite 3 so that it leaves small portion of thoracic sternite 8 visible, or somite 2 as wide as somite 3 so that thoracic sternite 8 not visible. Vulva of full-grown, mature females (Figs 15; 18) relatively small, not greatly enlarged, extending from suture 5/6 to suture 6/7, oblong or triangular vulvar cover (no evidence of a vulvar cover in small P. surugensis n. comb.; Fig. 14).</p> <p>REMARKS</p> <p>Serène &amp; Vadon (1981: 127) suggested the inclusion of Carcinoplax bispinosa and C. surugensis in a separate genus based on their characteristic G1. Guinot (1969b: 526) commented on the differences between C. surugensis and other Carcinoplax species: wide sternum and abdomen, stout G1, and a G2 with a flagellum that is almost as long as the proximal part (peduncle) and ending in a pointed tip. It was nevertheless kept in Carcinoplax in her subsequent revision of the genus (Guinot 1989). Carcinoplax surugensis was considered closer to C. meridionalis based on the shape of the carapace (Guinot 1989: 303), even if the G1 of the latter, which proved to be similar, was not commented upon.Two species herein included in the new genus (C. meridionalis and C. victoriensis) were included by Guinot (1989: 314) in a list of eight “non-revised” species of Carcinoplax that are now, with only one exception, placed in other genera.</p> <p>Pycnoplax n. gen. is similar in the general shape of its carapace to Carcinoplax. A case in point is the remarkable similarity between the carapaces of P. bispinosa n. comb. and C. tenuidentata n. sp. (see Remarks for P. bispinosa n. comb. below). The morphology of the G1 of Pycnoplax n. gen. (thick and stout, in contrast to slender and dorso-ventrally thin in Carcinoplax), male abdomen (wider than in Carcinoplax), and vulva (smaller and typically having a vulvar cover in Pycnoplax n. gen. in contrast to the greatly expanded vulva lacking a vulvar cover in Carcinoplax), and a complete 6/7 thoracic suture (incomplete in Carcinoplax), however, clearly separates the two genera. There are also slight differences in the basal antennal article (wider in Pycnoplax n. gen. than in Carcinoplax) and the G2 (distal part relatively longer than proximal portion in Pycnoplax n. gen., much shorter in Carcinoplax, and the presence of proximal denticles on the distal part in Pycnoplax n. gen., absent in most species of Carcinoplax).</p> </div>	https://treatment.plazi.org/id/102B87CBFFB62557FF46FDDDFCD5FB56	Public Domain	No known copyright restrictions apply.

Front lamellar, straight, not marked by median notch, bordered by tomentum. Slight notch between front, inner edge of supraorbital border.Supraorbital borders sinuous, margins granular.Suborbital borders granular, each with short, blunt inner tooth not visible dorsally. Outer orbital angle with blunt, granular tooth; 2 granular anterolateral teeth on each side of carapace; first triangular, dorso-ventrally flat, second acute, oriented dorsally; margin between anterolateral teeth nearly straight. Posterolateral borders arched.</p> <p>Subhepatic, pterygostomial regions, pterygostomial crest, merus of third maxilliped endopod with short, conspicuous granules.</p> <p>Eye peduncles (Figs 16A; 17) short (0.2 front width), dorsal surface granular, cornea slightly expanded distally.</p> <p>Chelipeds (P1) (Fig. 17) nearly equal in males, females; fingers slender, longer than propodus, with blunt teeth, fingers dark brown in males except short proximal portion of dactylus, about two-thirds dark brown in females.Dactylus, propodus, carpus, merus with short granules in small specimens (granules only on merus of holotype, largest specimens); dactylus, propodus, merus with some setae in small specimens; broad, curved, acute-tipped tooth on inner (ventral), proximal margin of carpus.

The G1 and G2 were fully developed and the P1 smooth and seemingly fully developed in the largest males, precluding the possibility that only pre-adult specimens were available. None of the two females examined was ovigerous but one (cl 4.1 mm, cw 5.0 mm) had fully developed pleopods and a vulvar cover, suggesting that it was a mature individual. The small number of specimens collected, all from one locality, does not exclude the possibility, however, that the species attains a larger size.</p> <p>It differs from its congeners by the relative size of the anterolateral teeth, particularly the second one, which is smaller and less salient than in any of the species of Pycnoplax n. gen. The overall body size of the know specimens is also much smaller than in the other species.</p> <p>The specimens were first identified as a possible new species of Carcinoplax by T. Komai (CBM), who generously allowed me to describe them as part of this work.</p> </div>	https://treatment.plazi.org/id/102B87CBFFB8255EFF49FBC6FC86FA98	Public Domain	No known copyright restrictions apply.

The carapace of specimens from New Zealand has been described as “pale vermillion, darker anteriorly” (McLay 1988: 258, as C. victoriensis).</p> <p>REMARKS</p> <p>Guinot (1969b: 524) placed Carcinoplax meridionalis by itself in one of three groups of Carcinoplax species because of a sternum that was narrower, particularly between the P1 (“plastron sternal moins élargi, notamment entre les p1”). Serène &amp; Lohavanijaya (1973: 67) considered the species as “close” to Carcinoplax angusta (Rathbun, 1914), actually not belonging in Carcinoplax but a euryplacid (see Remarks for Carcinoplax), on account of the “stout and smooth” P1 and the narrow male abdomen and G1. The similarities in these last two characters are erroneous since both the male abdomen and the G1 are much narrower in than in P. meridionalis n. comb.</p> <p>Diagnostic of the species is a second anterolateral tooth that is acute and has a curved tip (see Rathbun 1923: pl. 18, fig. 1; Guinot 1989: pl. 12, fig. G; Poore 2004: fig. 140c, as C. meridionalis). The inner suborbital tooth is conspicuous and visible dorsally as in P. victoriensis n. comb. The G1 is proximally thick and spinous but the distal part is narrow (Serène &amp; Lohavanijaya 1973: figs 168- 170, as C. meridionalis). The G2 is longer than the G1, its distal part almost as long as the proximal part (peduncle), the tip is not expanded and it has several minute spinules (Serène &amp; Lohavanijaya 1973: figs 171-173, as C. meridionalis). The vulva has a thick, oblong vulvar cover on its outer margin. Differences with P. victoriensis n. comb., with which it is apparently sympatric, are given in the Remarks section of P. victoriensis n. comb. (see below).</p> <p>The East China Sea specimens identified as C. meridionalis by Chen (1984: 194, 197) do not belong to the species, which is known only from temperate</p> <p>Revision of Goneplacinae (Crustacea, Brachyura)</p> <p>Australia and New Zealand.

Both species appear to be sympatric to southeastern Australia. They can be easily distinguished because the second anterolateral tooth is short and triangular in P. victoriensis n. comb. but curved and conspicuously acute in P. meridionalis n. comb. (see Rathbun 1923: pl. 18, fig. 1, pl. 19, fig. 1; Guinot 1989: pl. 12, figs F, G; Poore 2004: fig. 140c, d, as C. victoriensis and C. meridionalis). The carapace has two slight horizontal ridges across (see Rathbun 1923: pl. 19, fig. 1; Guinot 1989: pl. 12, fig. F, as C. victoriensis), which are absent in P. meridionalis n. comb. The telson of the male abdomen has a rounded margin whereas it is more pointed in P. meridionalis n. comb. The G1 is stout, spinous, and narrower distally, although not as narrow as in P. meridionalis n. comb. (see Serène &amp; Lohavanijaya 1973: figs 168-170, as C. meridionalis); the G2 is longer than the G1, its flagellum shorter than the proximal part (peduncle), and the tip with two terminal spinules. The vulva of adult females has a conspicuous triangular vulvar cover (Fig. 18), whereas it is oblong in P. meridionalis n. comb. The carapace of live P. victoriensis n. comb. has large pink blotches, dark-red bands on the ambulatory leg meri, and white fingers that can be dark brown at the tips, whereas in P. meridionalis n. comb. the carapace is similarly pink without the red bands on the ambulatory legs and dark brown fingers (see Poore 2004: pl. 24, figs a, b, as C. meridionalis).</p> </div>	https://treatment.plazi.org/id/102B87CBFFBE255DFC8EFA62FEC2F97B	Public Domain	No known copyright restrictions apply.

Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers moderately slender or thick, shorter than propodus, darker in colour; carpus with tooth on inner margin. Dorsal margins of meri, carpi, propodi of ambulatory legs (P2-P5) unarmed; dactyli slender, carinated (smooth in T. cooki n. comb., T. digitodentata n. sp.), setose. Male abdomen with 6 freely-movable somites plus telson, narrowly triangular, somites 4-6 gradually decreasing in length from somite 3 (widest somite). Telson approximately as long as wide. Somite 3 covers space between P5 coxae, somite 2 slightly narrower than or as short as somite 3 so that somites 1, 2 leave small, often triangular portion of thoracic sternite 8 visible, or no portion is visible (Guinot &amp; Richer de Forges 1981b: fig. 9A). G1 (Figs 20C; 23D; 25C) sinuous or curved, slightly broadened proximally, stout; truncated or pointed tip. G2 (Figs 20D; 23E; 25D) slender, slightly or moderately longer than G1, flagellum shorter than proximal part (peduncle), tip pointed or with 2 spinules. Penis arising from P5 coxa, moderate size; broad, soft proximal expansion. Female abdomen (female of T. digitodentata n. sp. unknown) with 6 freelymovable somites, wide. Telson triangular. Somite 3 covers space between P5 coxae, somite 2 only slightly narrower than somite 3, thoracic sternite 8 not visible or only small portion visible (Guinot 1969b: fig. 60, as Carcinoplax cooki). Vulva of mature females (Figs 19; 22) small, extending from suture 5/6 to suture 6/7, vulvar cover present.</p> <p>REMARKS</p> <p>Thyraplax crosnieri n. comb. and T. cooki n. comb. were originally included in the genus Carcinoplax. The distinct morphology of these species in relation to other Carcinoplax species was noted by other authors. Rathbun (1906: 835) remarked that the nature of the anterolateral teeth and the convexity of the carapace of T. cooki n. comb. (as Pilumnoplax cooki) distinguished the species “from all others”. Guinot (1989: 314) included this two species in a list of eight “non-revised” species of Carcinoplax that proved, with only one exception, to belong to other genera. In describing Carcinoplax crosnieri, Guinot &amp; Richer de Forges (1981b: 252) “provisionally” included the species in Carcinoplax awaiting revision of the genus since it did not resemble any known species in the genus (“dans l’attente de sa révision, ne nous paraît ressembler à aucune autre espèce connue de ce genre”). Serène &amp; Vadon (1981: 126) placed T. cooki n. comb. (as C. cooki) as “probably” in a group of species of Carcinoplax sensu lato where the outer orbital teeth appear as an extension of the orbit itself. Indeed, the shape of the carapace, with rounded and short anterolateral margins, a single anterolateral tooth, and long posterolateral borders that are markedly arched so that the widest portion of the carapace is actually below the anterolateral teeth are in sharp contrast to the carapace of Carcinoplax, with two teeth (one in C. ischurodous) on each of the slightly longer anterolateral borders and posterolateral borders that decrease in width behind the last anterolateral teeth. There is also a slight carina or prominence along the anterolateral borders of the carapace, which is absent in Carcinoplax.</p> <p>Some characters more significant than the general shape of the carapace provide evidence to support a separation of these two species, plus three new ones, from Carcinoplax sensu lato. The G1 varies in shape but it is never as slender and thin as in Carcinoplax; the G2 is slightly but clearly longer than the G1, a rare occurrence in Carcinoplax; the vulva is reduced in size and has a vulvar cover (absent in Carcinoplax); and the 7/8 thoracic suture is clearly complete (Figs 19; 22) in contrast to Carcinoplax, although it is shown as incomplete by Guinot &amp; Richer de Forges (1981b: fig. 9A, as Carcinoplax crosnieri). The P2-P5 dactyli of some of the species is carinated but they have smooth surfaces in Carcinoplax.</p> <p>Four of the five species of Thyraplax n. gen. have been found only on the eastern and southern limits of the Indo-West Pacific region, areas where species of Carcinoplax are absent or are fewer in number than in the western Pacific Ocean.</p> </div>	https://treatment.plazi.org/id/102B87CBFFBD2522FC92FF31FBF1F97C	Public Domain	No known copyright restrictions apply.

The specimen from Japan shown by Ikeda (1998), however, is mostly orange.</p> <p>REMARKS</p> <p>The large size of the male holotype (cl 31.8 mm, cw 38.1 mm, MNHN-B 6834), which was collected from traps, exhibits some important differences from the rest of the material available for examination, which was dredged. The additional material includes eight much smaller males varying from cl 13.9 mm, cw 18.1 mm (New Caledonia, MNHN-B 29399) to cl 21.4 mm, cw 27.0 mm (Philippine Is, ZRC 2004.0720). The tooth-like tubercles at the base of the telson of the holotype (Guinot &amp; Richer de Forges 1981b: 252) are obsolete or much smaller and obtuse in smaller males. More significant are differences in the G1 and G2. The distal portion of the G1 of the holotype (Guinot &amp; Richer de Forges 1981b: fig. 10I-K) is thicker, straighter, and provided with more denticles and the basal portion slightly wider than in the smaller males, where the distal third is bent outwardly. A short row of plumose setae was found on the outer margin of the base of the distal portion in a small male (cl 16.5 mm, cw 21.5 mm, ZRC 2004.0720). The G1 is nearly straight, however, in a medium size individual (cl 12.5 mm, cw 15.7 mm; ZRC 2006.0199).The G2 of the holotype is similarly straighter than in the smaller males.These differences appear to be due to size rather than species-specific. The examination of the G1 and G2 of specimens that are intermediate in size between the males examined here and the holotype should confirm or reject this assumption.</p> <p>The vulva of small females is oval, extending from suture 5/6 to suture 6/7, and partially covered with a triangular vulvar cover on the postero-lateral margin. In larger females (Fig. 19) the vulva is crescent-shaped and the vulvar cover is thicker and larger than in small females. The vulvar cover overhangs the vulva to almost reach the inner margin, thus creating two apertures, an anterior and a posterior one.</p> <p>Thyraplax crosnieri n. comb. is close to T. cooki (Rathbun, 1906) n. comb. Differences between the two species are outlined in the Remarks section for the latter (see below); differences between all five species of Thyraplax n. gen. are summarized in Table 3.</p> </div>	https://treatment.plazi.org/id/102B87CBFFC32521FEABFCD8FF03FDB1	Public Domain	No known copyright restrictions apply.

Depth: 430-1000 m. Also dredged from a station recorded at 500-1200 m.</p> <p>REMARKS</p> <p>Guinot (1969b: 524) placed T. cooki n. comb. by itself in one of three groups of Carcinoplax sensu lato. Several characters were given for this classification: G1 “analogous” to those of C. longimana (de Haan, 1833), relatively narrow sternum (particularly near the chelipeds and on the posterior portion), and narrow male abdomen.</p> <p>Thyraplax cooki n. comb. is close to T. crosnieri n. comb. in the shape of the carapace, the size of the chelipeds (P1), and in the relative length of the ambulatory legs (P2-P5). The anterolateral margin of T. cooki n. comb. has a slight tooth-like eminence (see Guinot 1989: fig. 42, pl. 11, fig. G), which was described as a “blunt obtuse-angled tooth” in the original description (Rathbun 1906: 835). In contrast, the margin of T. crosnieri n. comb. has a slight carina that is sometimes marked by a median notch (Fig. 13C). The anterolateral teeth are dorsally oriented (although more conspicuously so in T. cooki n. comb.) and obtuse in both species, but were nevertheless found to be acute in some specimens of T. cooki n. comb. The main differences that separate the two species are in the morphologies of their G1, G2, and vulvae respectively. The G1 of T. cooki n. comb. is slender, straight, and its distal portions provided with small teeth (Guinot 1969b: fig. 77a, b) whereas that of T. crosnieri n. comb. is stouter and the distal third portion bent outwardly (Guinot &amp; Richer de Forges 1981b: fig. 10I). The G2 of T. cooki n. comb. is straight, with two equal apical spinules (Guinot 1969b: fig. 78) whereas that of T. crosnieri n. comb. is slightly bent distally and the tip has two unequal spinules (Guinot &amp; Richer de Forges 1981b: fig. 10L). The vulva of T. cooki n. comb. is large, round, and it extends from su- ture 5/6 to suture 6/7 of thoracic sternite 6. Each vulva has a small, spherical, low vulvar cover on its postero-external margin that does not reach the anterior margin of the vulva. The vulva of T. crosnieri n. comb. (Fig. 19) is in the same position but the opening is oval, smaller than in T. cooki n. comb., and the vulvar cover is large and triangular.</p> <p>Somite 6 of the abdomen of the male holotype (USNM 29364) and of a second male from the type locality (MNHN-B 10557) showed a slight triangular eminence on the outer margin of each distal end, a character not observed among the males from French Polynesia and New Caledonia that were examined. Otherwise, all other characters of the two Hawaiian specimens agreed with those from southern localities.</p></div> 	https://treatment.plazi.org/id/102B87CBFFC12526FF2CFD5BFE9FF97C	Public Domain	No known copyright restrictions apply.

G2 (Capart 1951: figs 4, 5, 12; Guinot 1969b: fig. 72; 1989: fig. 46B, as Carcinoplax barnardi; Guinot &amp; Castro 2007: fig. 3D) slender, slightly longer or slightly shorter than G1, flagellum shorter than proximal part (peduncle), curved; slightly-expanded tip with 1 or 2 spinules. Penis arising from P5 coxa, moderate size; broad, soft proximal expansion. Female abdomen with 6 freely-movable somites, wide.Telson much wider than long. Somite 3 covers space between P5 coxae, somite 2 slightly narrower than somite 3 but somites 1, 2 leave relatively large portion of thoracic sternite 8 visible. Vulva of mature females round, extending from oblique 5/6 suture to 6/7 suture or to median portion of thoracic sternite 6, covered by soft membrane, vulvar cover absent.</p> <p>REMARKS</p> <p>Examination of numerous specimens of the type species of Goneplax, G. rhomboides (Linnaeus, 1758), plus three other species sharing several important characters with the type species, clearly shows that Goneplax should be restricted to these four species. All four species are found in the Atlantic Ocean although one species (G. rhomboides) is also found in the Mediterranean Sea, while another (G. clevai Guinot &amp; Castro, 2007), spans the Atlantic and Indian Ocean coasts of Africa and hence is found in both the Eastern Atlantic and Indo-West Pacific regions.</p> <p>The implication that Goneplax should be restricted to species found outside the Indo-West Pacific region was first expressed by Guinot (1969b: 520). Serène &amp; Vadon (1981: 126) suggested the creation of “one or two new genera” for two Indo-West Pacific species, Goneplax renoculis Rathbun, 1914, and G. sinuatifrons Miers, 1886. Serène &amp; Soh (1976) had previously erected the genus Singhaplax for two Indo-West Pacific species previously attributed to Goneplax: G. nipponensis Yokoya, 1933, and G. ockelmanni Serène, 1971 (see Remarks for Singhaplax below). More recently, Števčić (2005) included two of the Indo-West Pacific species of Goneplax sensu lato (G. maldivensis Rathbun, 1902, actually a euryplacid, and G. sinuatifrons) in two new genera. The taxa were listed without giving descriptions or definitions to differentiate them from other genera, therefore they must be considered nomina nuda (ICZN 1999: Article 13a).</p> <p>The six Indo-West Pacific species of Goneplax sensu stricto remaining after the description of Singhaplax Serène &amp; Soh, 1976, are herein placed in five separate genera, Goneplacoides n. gen., Hadroplax n. gen., Microgoneplax n. gen., Neogoneplax n. gen., and Paragoneplax n. gen. A seventh species, G. maldivensis, is being placed in the family Euryplacidae.</p> <p>The five new genera, as well as Ommatocarcinus White, 1852, and Neommatocarcinus Takeda &amp; Miyake, 1969, share with Goneplax sensu stricto and Singhaplax elongated orbits and eye peduncles and wide, transversely rectangular and relatively short carapaces with conspicuous, often acute outer orbital teeth. Also included in this group is Frevillea A. Milne-Edwards, 1880, and G. maldivensis, both euryplacids. The use of carapace shape to separate between Goneplax sensu stricto and Carcinoplax sensu stricto is only a matter of convenience (see Remarks for subfamily Goneplacinae above). The evolution of elongated eye peduncles among brachyuran crabs was suggested by Barnes (1968) as an adaptation to a burrowing mode of life and the avoidance of predators while feeding on the surface of the sediment. Other characters that separate Goneplax sensu stricto from the six Indo-West Pacific genera containing species that were formerly included in Goneplax sensu lato are summarized in Table 4.</p> <p>Rathbun (1897: 167) clarified the validity of the original name Goneplax over Goneplat or Gonoplax, which are considered typographical errors (also see Melville &amp; Smith 1987: 99).</p> </div>	https://treatment.plazi.org/id/102B87CBFFCE252CFF10FB47FC3CFC35	Public Domain	No known copyright restrictions apply.

Depth: 200- 586 m.</p> <p>REMARKS</p> <p>Capart (1951: 172) described Goneplax barnardi n. comb. under Carcinoplax on account of the shape of the carapace, the relatively short eye peduncles, and “the other characteristics of the genus”. He agreed that Carcinoplax was nevertheless close to Goneplax and that the male first pleopods of his new species were difficult to be used as a diagnostic character. In contrast to Carcinoplax, G. barnardi n. comb. has longer eye peduncles, the dorsal margins of the ambulatory leg (P2-P5) meri are armed with an acute distal tooth (although present in C. spinosissima Rathbun, 1914), and the dactyli are slender and have a carina on each side. Sakai (1976: 531, as Carcinoplax barnardi) mentioned that the species “seems to belong to Psopheticus, near P. insignis ” but without giving any explanations.</p> <p>Goneplax barnardi n. comb. may be distinguished from G. rhomboides and G. clevai, which are also found along the West African coast, by the rounded anterolateral borders of its carapace and the presence of conspicuous tubercles on the subhepatic region (Fig. 27B). The borders are straight or nearly straight and the subhepatic region lacks large tubercles in G. rhomboides (Fig. 27A) and G. clevai (see Guinot 1989: fig. 45, as [Carcinoplax] barnardi; Guinot &amp; Castro 2007: figs 1-3). Also diagnostic is the length of its eye peduncles. They are much shorter in G. barnardi n. comb. (0.4 front width; Fig. 27B) than in G. rhomboides, where it is as long as or slightly longer than the front width (Fig. 27A), or in G. clevai, where they are slightly shorter than the front width (0.8 front width). There are also probable differences in colour. Goneplax barnardi n. comb. was described as “rose bistre” (dark-brown pink) (Capart 1951: 172), while G. rhomboides is known to have a “yellow to pale red, sometimes fringed with violet” carapace and “yellow to orange” chelipeds and ambulatory legs (Ingle 1980: 109). Goneplax clevai was described by Barnard (1950: 285, as G. angulata) as “pale pink, or salmon, or pinky-cream, carapace and chelipeds more or less vermiculate or mottled”. A freshly preserved specimen had irregular, purple-pink reticulations on the anterior portion of the carapace; the dorsal surfaces of the chelipeds and eye peduncles were light purplepink (see Guinot &amp; Castro 2007: fig. 2B).</p> </div>	https://treatment.plazi.org/id/102B87CBFFD22533FD00FAA5FBB8FD72	Public Domain	No known copyright restrictions apply.

The two species are sympatric along the coast of West Africa but the extent of their overlap remains unknown because many African records of G. rhomboides in the literature are most probably from misidentified specimens.</p> <p>Goneplax clevai is best distinguished from G. rhomboides and G. barnardi n. comb. by the length of its eye peduncles, which is somewhat intermediate between its two congeners: 0.8 of the front width (see Guinot 1989: fig 45, as [Carcinoplax] barnardi; Guinot &amp; Castro 2007: fig. 4A), not as long as in G. rhomboides (where it is as long or slightly longer than the front width; see Fig. 27A; Guinot &amp; Castro: fig. 4B) but much longer than that of G. barnardi n. comb. (0.4 of the length of the front; see Fig. 27B). There is some variation in the shape of the anterolateral borders and the outer orbital and anterolateral teeth among specimens of G. rhomboides so that these characters are not always reliable for differentiating between the two species (see Guinot &amp; Castro 2007). The anterolateral borders of G. clevai are straight but rounded in G. barnardi n. comb. There are also differences in the morphologies of the front, chelipeds, overall shape of the carapace, and colour between the three species (see Guinot &amp; Castro 2007).</p> </div>	https://treatment.plazi.org/id/102B87CBFFD32531FD69FD1BFE15FBD5	Public Domain	No known copyright restrictions apply.

Depth: 156- 400 m. Also dredged from a station recorded at 372- 660 m.</p> <p>COLOUR</p> <p>A photograph of a freshly collected female specimen from New Caledonia (MNHN-B 29262) showed a mottled light red carapace, chelipeds, and ambulatory legs. Two dark red spots showed on each cheliped, one on the dactylus and one on the distal end of the outer margin of the propodus.</p> <p>REMARKS</p> <p>Most of the unique characters of Goneplacoides marivenae n. comb. are discussed in the Description and Remarks for Goneplacoides n. gen. (see above).</p> <p>Komatsu &amp; Takeda (2003) described Goneplax marivenae from the Philippine Is and G. megalops from Japan (type locality: Kerama Is, Ryukyu Is). Goneplax megalops was described as “most similar” to Goneplax marivenae except that: 1) the outer orbital teeth projected beyond the anterolateral teeth in G. megalops (Komatsu &amp; Takeda 2003: figs 4a, 7B) but not in Goneplax marivenae, where both teeth have about the same length (Komatsu &amp; Takeda 2003: figs 4a, 7A); 2) the mesial margins of the G1 of G. megalops were fringed with short simple setae in contrast with the plumose setae that were found along the entire border of the G1 of Goneplax marivenae; 3) the tip of the G1 of G. megalops was narrower in G. megalops than in Goneplax marivenae; and 4) Goneplax marivenae was “about twice as large as G. megalops ” (Komatsu &amp; Takeda 2003: 1249). All of these differences are explained by the relative size of the specimens used in the two descriptions. Goneplax megalops was described from nine small specimens (cl 3.4 mm, cw 4.6 mm to cl 7.4 mm, cw 11.2 mm; male holotype, cl 6.0 mm, cw 9.1 mm, CBM-ZC 7031) whereas Goneplax marivenae was described from four larger specimens (cl 10.2 mm, cw 15.7 mm to cl 12.3 mm, cw 19.1 mm). Among the specimens from one station in the Kai Is, Indonesia (MNHN-B 29217), the five smaller individuals (four males and one female, cl 4.5 mm, cw 6.5 mm to cl 5.0 mm, cw 7.4 mm) had outer orbital teeth that projected beyond the anterolateral teeth as in G. megalops, while in the largest one (female, cl 6.8 mm, cw 10.1 mm) the outer orbital teeth did not as in Goneplax marivenae. All of the remaining 53 specimens examined (including the holotype of G. megalops) during this study, which varied from a pre-adult female (cl 3.4 mm, cw 4.2 mm, MNHN- B 29346) to a female (cl 8.7 mm, cw 13.6 mm, MNHN-B 29223) confirmed that in the smaller individuals (cl shorter than 6.5 mm) the outer orbital teeth always projected beyond the anterolateral teeth but not in the larger individuals. The differences between the G1 of both species are also a function of relative size, the number and type of setae and the relative width of the tip vary according to size. Goneplax megalops, is therefore a synonym of Goneplax marivenae. Both descriptions appear in the same publication but the name Goneplax marivenae is selected as it appears first in the publication, and to prevent confusion since the epithet megalops has already been used in another species.</p> <p>An incomplete male specimen from Taiwan (NTOU) appears to be identical to G. marivenae. The specimen is supposedly the same identified as a female of Singhaplax nipponensis (Yokoya, 1933) (but Goneplax nipponensis in Fig. 6) by Ho et al. (2004: 659). The figure, however, shows a slen- der P5 dactylus instead of the broad dactylus of G. marivenae.</p> <p>Two pre-adult males from Indonesia identified as Goneplax maldivensis, by Tesch (1918: 183, pl. 9, fig. 1) do not belong to this species (actually in Euryplacidae), an observation previously made by Guinot (1969b: 518). The specimens could belong to G. marivenae instead. The rounded outer orbital angle as depicted by Tesch is not characteristic of G. marivenae but the broad P5 dactylus, the general shape of the carapace, eye peduncles, and abdomen are indeed diagnostic of the species. The specimen (ZMA De 241733) was unfortunately damaged beyond recognition.</p> <p>A photograph of a specimen with a completely red carapace had strong resemblance to G. marivenae n. comb. The specimen, collected from the Gemini seamounts east of New Caledonia, was unfortunately lost. It may represent a yet undescribed species of Goneplacoides n. gen.</p></div> 	https://treatment.plazi.org/id/102B87CBFFD62535FC99FB04FC60FCD2	Public Domain	No known copyright restrictions apply.

Notch between front, inner edge of supraorbital border absent. Orbits wide, greatly expanded distally; supraorbital borders conspicuously sinuous; suborbital borders sinuous, with short, wide inner tooth not visible dorsally. Dorsal surface of carapace smooth, moderately convex, without clear indication of regions. Outer orbital angle with conspicuous, anteriorly directed, acute tooth. Nearly straight lateral borders without anterolateral teeth. Basal antennular articles large so they cannot be folded into enlarged fossae (Serène &amp; Umali 1972: fig. 73). Basal antennal article short, distalmost (third) article nearly reaches front. Eye peduncles (Miers 1886: pl. 20, fig. 2b, as G. sinuatifrons) relatively long, only slightly shorter than front (0.8 front width); cornea reniform, dorso-ventrally flattened, nearly divided into anterior, posterior portions. Anterior border of endostome well demarcated from buccal cavern, ridges faint but clearly defined. Third maxillipeds nearly completely close the buccal cavern. No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; suture 2/3 fused but visible in some specimens, sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete. Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers long, slender, shovel-like, curved, shorter than elongated propodus; carpus with conspicuous, acute tooth on inner margin; merus with conspicuous tooth on inner (ventral) margin. Dorsal margins of ambulatory leg (P2-P4) meri with acute distal tooth, P5 unarmed; dactyli of P2-P4 slender, with carina on each side. Male abdomen (Tesch 1918: pl. 9, fig. 2 a; Serène &amp; Umali 1972: fig. 77, as G. sinuatifrons) with 6 freely-movable somites plus telson, wide, somites 4-6 gradually decreasing in width from somite 3 (widest somite). Telson wide, wider than long. Somite 3 covers space between P5 coxae, somite 2 narrower than somite 3; somites 1, 2 leave large portion of thoracic sternite 8 visible. G1 (Serène &amp; Umali 1972: figs 78, 79, as G. sinuatifrons) long, slender, slightly broadened proximally, bent outwardly at distal end. G2 (Serène &amp; Umali 1972: figs 80, 81, as G. sinuatifrons) slender, slightly longer than G1, flagellum slightly longer than proximal part (peduncle), expanded. Penis arising from P5 coxa, moderate size, soft proximal expansion. Female abdomen with 6 freely-movable somites, wide. Telson much wider than long. Somite 3 covers space between P5 coxae, somite 2 slightly narrower than somite 3; somites 1, 2 leave small portion of thoracic sternite 8 visible. Vulva of mature females small, ovoid, extending from 5/6 suture to median portion of thoracic sternite 6, vulvar cover absent, covered by soft membrane.</p> <p>REMARKS</p> <p>Teschia Števčić, 2005, created for Goneplax sinuatifrons Miers, 1886, was included in a list of “new genera incertae sedis ” (Števčić 2005: 134) without any indications as to their inclusion in any particular supra-generic taxa. The generic name is unavailable since it was not accompanied by a description or definition to differentiate it from other genera (ICZN 1999: Article 13.1).</p> <p>Guinot (1969b: 522) questioned the inclusion of G. sinuatifrons in Goneplax sensu lato, and Serène &amp; Vadon (1981: 126) suggested its elevation as a new genus. Serène &amp; Umali (1972: 82) similarly explained that their new species, Singhaplax ockelmanni (Serène, 1971), was not congeneric with G. sinuatifrons on account of the structure of their respective antennules and G1. Apparently unique among the Goneplacidae sensu stricto is the presence of basal antennular articles that are so long that they do not fit into the fossae, even if the fossae are enlarged (see Serène &amp; Umali 1972: fig. 73). Also unique is the shape of the G2, with an enlarged tip (see Serène &amp; Umali 1972: figs 80, 81) and an unusually large portion of thoracic sternite 8 left visible by the male abdomen. The nearly square appearance of the carapace, without anterolateral teeth, is similar to that of Paragoneplax serenei (Zarenkov, 1972) n. comb., but in the lat- ter the G2 is much shorter than in H. sinuatifrons n. comb. and the G1 is uniquely twisted. The 2/3 thoracic suture was fused but still visible in all eight specimens (including five pre-adults) collected in Indonesia by the Siboga Expedition (largest female, cl 6.1 mm, cw 9.2 mm; ZMA De 241737) but not fused in a small female (cl 4.3 mm, cw 6.4 mm; MNHN-B 10306). The suture was not fused in the female holotype (cl 6.3 mm, cw 9.7 mm; BMNH 18.84.31) and in a large male (cl 7.5 mm, cw 11.2 mm; MNHN-B 10322). Other characters that separate Hadroplax n. gen. from Goneplax sensu stricto and the five Indo-West Pacific genera containing species formerly included in Goneplax sensu lato are summarized in Table 4.</p> <p>Goneplax nipponensis Yokoya, 1933 could also represent a second species of Hadroplax n. gen. (see Remarks for Singhaplax styrax n. sp. below).</p> </div>	https://treatment.plazi.org/id/102B87CBFFD5253BFC96FCBBFB9AFCD2	Public Domain	No known copyright restrictions apply.

Slight notch between front, inner edge of supraorbital border; orbits wide, greatly expanded distally; supraorbital borders conspicuously convex; suborbital borders convex, with 1 or 2 slight, obtuse inner teeth not visible dorsally; anterolateral borders short, straight. Dorsal surface of carapace smooth or with slight horizontal ridges, moderately convex, without clear indication of regions. Outer orbital angle with conspicuous, acute tooth; acute anterolateral tooth on each side of carapace (much reduced in N. costata n. sp.). Basal antennal article short, distalmost (third) article nearly reaches front. Eye peduncles (Figs 28B; 30A; 31; 33A; 34) long, shorter than or longer than front (0.8-1.1 front width); cornea strongly reniform, dorso-ventrally flattened, nearly divided into anterior and posterior portions. Anterior border of endostome well demarcated from buccal cavern, ridges faint but clearly defined. Third maxillipeds nearly completely close the buccal cavern. No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete (Fig. 32). Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers (Figs 28B; 31; 34) long, slender, shovel-like, curved, pollex higher than dactylus in large individuals, shorter than elongated propodus; dactylus light in colour, without dark portion; carpus with conspicuous tooth on inner margin. Dorsal margins of ambulatory leg (P2-P5) meri unarmed (N. costata n. sp.; Fig. 31), with acute distal tooth (N. renoculis n. comb.; Fig. 28B), or several teeth (N. serratipes n. sp.; Figs 33B, 34); dactyli slender, with carina on each side, non-setose. Male abdomen (Figs 30B; 33C; Chen 1998: fig. 11-3, as G. renoculis) with 6 freely-movable somites plus telson, wide, somites 4-6 gradually decreasing in width from somite 3 (widest somite).Telson wide, clearly longer than wide. Somite 3 covers space between P5 coxae, somite 2 narrower than somite 3; somites 1, 2 leave small to large portion of thoracic sternite 8 visible. G1 varies from long, slender, slightly sinuous, slightly broadened proximally (Fig. 30C) to stout, short, with obtuse tip (Fig. 33D; Chen 1998: fig. 11-4, as G. renoculis). G2 (Figs 30D; 33E) slender, slightly shorter to slightly longer than G1, flagellum slightly longer than proximal part (peduncle), tip curved or straight, pointed. Penis arising from P5 coxa, moderate size; broad, soft proximal expansion. Female abdomen (Dai &amp; Yang 1991: fig. 198-2, as G. renoculis) with 6 freely-movable somites, wide. Telson much wider than long. Somite 3 covers space between P5 coxae, somite 2 slightly narrower than somite 3; somites 1, 2 leave small portion of thoracic sternite 8 visible. Vulva of mature females (Fig. 32) small, oval, extending from 5/6 suture to median portion of thoracic sternite 6, vulvar cover present.</p> <p>REMARKS</p> <p>The new genus is described for Goneplax renoculis Rathbun, 1914, which is different from the four mostly Atlantic species of Goneplax sensu stricto. The polyphyletic nature of Goneplax sensu lato and the questions surrounding the position of the Indo-West Pacific species of the genus are discussed in the Remarks section for Goneplax (see above).</p> <p>Characters that separate Neogoneplax n. gen. from Goneplax sensu stricto and the five Indo-West Pacific genera that were formerly included in Goneplax sensu lato are summarized in Table 4.</p> </div>	https://treatment.plazi.org/id/102B87CBFFD82539FF53FCDBFBD7FD91	Public Domain	No known copyright restrictions apply.

Depth: 80- 512 m. Specimens were also obtained from tangle nets of local fishermen in the Philippines that obtained material estimated to be at least 50 m.</p> <p>COLOUR</p> <p>A photograph of freshly collected female specimen from the Solomon Is (MNHN-B 29204) showed red orange to red reticulations and dots on the carapace and red dots on the chelipeds, similar to those illustrated by Sakai (1976: pl. 188, fig. 1) and Miyake (1991: pl. 50, fig. 3) from Japan, and Ho et al. (2004: fig. 6D) from Taiwan. Colour photographs of freshly collected specimens from the Philippine Is (PANGLAO 2005) confirm this colour pattern.</p> <p>REMARKS</p> <p>The abundant material from Taiwan to New Caledonia that was examined agrees well with the female holotype of Goneplax renoculis. Diagnostic characters of the species is an acute, anteriorly curved, anterolateral tooth that is in a straight line below the base of the similarly acute and anteriorly curved but longer outer orbital tooth (Fig. 28B). The anterolateral tooth emerges after a short, straight portion of the anterolateral border of the carapace. Also diagnostic is a small tooth on the dorsal, distal end of the merus of each ambulatory leg (P2-P5) (Fig. 28B). The propodi of the P5 may have some sparse setae but are not fringed by them.The carapace front is deflexed, and the eye peduncle is 1.2-1.3 of the front width. The eyes are strongly reniform. Large males have two slightly raised horizontal ridges across the width of the carapace.</p> <p>The G1 is stout, short, and with a truncate tip (Chen 1998: fig. 11-4, as Goneplax renoculis). The G2 is slightly shorter than the G1, with the flagellum shorter than the basal part, and a pointed tip. The vulva of mature females extends from the margin of suture 5/6 to the margin of suture 6/7. It is covered by a large, salient, globular vulvar cover that leaves a large, semi-circular anterolateral opening. Suture 6/7 ends at the vulva, leaving a large, flat area between suture 5/6 and complete suture 6/7 that connects directly with the anterior portion of the thoracic sternum.</p> <p>No specimens from Japan could be examined during this study. The anterolateral teeth of Japanese specimens illustrated by Sakai (1935: pl. 54, fig. 4; 1939: pl. 67, fig. 4; 1965: pl. 84, fig. 2; 1976: pl. 188, fig. 1, as G. renoculis) are close to each other very much as in Goneplacoides marivenae n. comb. (Fig. 28A), which is found in Japan, instead of being separated by a straight margin as in N. renoculis n. comb. (Fig. 28B). The meri of the ambulatory legs (P2-P5) of Sakai’s specimens, however, were each armed with a distal tooth unlike the smooth meri of G. marivenae n. comb. (Fig. 28A). The colour of Sakai’s illustration (Sakai 1976: pl. 188, fig. 1, as Goneplax renoculis) does</p> <p>A C D</p> <p>agree with the photograph of a freshly collected specimen from the Solomon Is (see below). The G1 of a small specimen (cl 5.2 mm, cw 7.3 mm; maximum size of males: cl 11.3 mm, cw 17.2 mm; maximum size of females: cl 10.1 mm, cw 16.0 mm) illustrated by Takeda &amp; Miyake (1968: fig. 8c, d, as G. renoculis) had a spade-like tip different from almost all specimens examined during this study and that illustrated by Chen (1998). The only exception was the G1 of a pre-adult male from the Kai Is, Indonesia (cl 4.0 mm, cw 5.0 mm, MNHN-B 29213), which was similar to that illustrated by Takeda &amp; Miyake (1968).</p> <p>An incomplete specimen from the Austral Is, French Polynesia (male, cl 9.8, cw 16.7 mm; MNHN-B 29780), the only one from French Polynesia examined, had a carapace, eye peduncles, and P2-P4 (P5 missing) similar to those of N. renoculis n. comb. The only cheliped remaining, however, had an unusually high pollex, and the G1 had a conspicuously pointed tip. It may represent a new species.</p> </div>	https://treatment.plazi.org/id/102B87CBFFD9253CFEBBFC0EFCDCFA79	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Depth: 225 m and from estimated depths of 50-500 m from tangle nets of local fishermen.</p> <p>DESCRIPTON</p> <p>Carapace (Figs 30A; 31) transversely rectangular,wider than long, anterolateral borders oblique from outer orbital tooth to posterior border. Carapace slightly convex, without clear indication of regions; ridge across anterior third portion; second, less conspicuous ridge on posterior third portion. Front sinuous, slightly deflected ventrally, marked by 2 slight emarginations, small median projection between emarginations. Notch between front, inner edge of supraorbital border absent. Supraorbital borders conspicuously bilobed; bordered by raised, finely granular edge, wider, sinuous along front; reduced, obtuse inner tooth. Suborbital borders granular, each with short, blunt inner tooth not visible dorsally. Long, slender, acute-tipped tooth on outer orbital angle; reduced anterolateral teeth appearing as slight prominence (obsolete in holotype) below outer orbital angle corresponding with outer margin of anterior ridge of carapace. Posterolateral borders oblique, nearly straight.</p> <p>Revision of Goneplacinae (Crustacea, Brachyura)</p> <p>Eye peduncles (Figs 30A; 31) long (1.1 front width), cornea reniform.</p> <p>Chelipeds (P1) (Fig. 31) slightly unequal in males, nearly equal in female paratype; fingers shovel-like, curved, slightly shorter than propodus, much shorter in heavier P1 of males, with blunt teeth, heavier P1 of males with fewer teeth on dactylus, large cutting edge on fixed finger; no dark colour on fingers. Broad, acute-tipped tooth on inner (ventral), proximal margin of carpus; row of conspicuous, simple setae along inner (ventral) margin of dactylus, propodus, merus; outer margin of merus with 12-24 small, triangular teeth in small male (reduced to large, blunt tubercles in larger holotype and paratypes). Ambulatory legs (P2-P5) (Fig. 31) stout, without teeth; varying number of setae on dorsal margins of carpus, propodi (P5 of female paratype with row of dense setae on dorsal margin of propodus, distal margin of carpus; proximal, ventral margin of dactylus); dactyli long, slender, each with carina along each side; length of P5 merus 0.7 cl.</p> <p>Male abdomen (Fig. 30B) wide, short, triangular; telson much wider than long. Somite 3 covers space between P5 coxae, carinated; somite 2 narrower than somite 3, leaving large portion of thoracic sternite 8 visible. G1 (Fig. 30C) slender, sinuous, distal part curved, inwardly oriented; obtuse tip. G2 (Fig. 30D) slender, slightly longer than G1, curved flagellum longer than proximal part (peduncle), pointed tip.</p> <p>Female abdomen wide, outer margin of thoracic sternites not visible.Telson much wider than long. Somite 3 covers space between P5 coxae, somites 1, 2 narrower than somite 3, leaving small portion of thoracic sternite 8 visible. Vulva (Fig. 32) of mature paratype narrow, elongated, extending along edge of suture 5/6 to median portion of thoracic sternite 6; median, triangular vulvar cover.</p> <p>COLOUR</p> <p>Photographs of freshly preserved material from the Philippine Is showed small red spots on the carapace and legs.</p> <p>REMARKS</p> <p>The new species is closest to N. serratipes n. sp. (see below). Both species can be easily differentiated by the absence or reduction of the anterolateral tooth in N. costata n. sp. (Figs 30A; 31) while there is a conspicuous, acute tooth in N. serratipes n. sp. (Figs 33A; 34); smooth meri of ambulatory legs (Fig. 31) in contrast to many teeth in N. serratipes n. sp. (Figs 33B; 34); the presence of a small, acute tooth on the outer (dorsal), distal margin of each of the chelipeds (Fig. 31) in contrast to a larger, blunt tooth in N. serratipes n. sp. (Fig. 34); the telson of the male abdomen is much shorter in N. serratipes n. sp. (Fig. 33C) than in N. costata n. sp. (Fig. 30B), smooth G1 (Fig. 30C) in contrast to a stout G1 with a bilobed tip with distinct denticles and setae in N. serratipes n. sp. (Fig. 33D).</p> <p>A damaged, incomplete specimen from New Caledonia (♂, cw 14.8 mm; MNHN-B 29777) also appears to belong to the new species. It was the only specimen from outside the Philippine Is examined.</p> </div>	https://treatment.plazi.org/id/102B87CBFFDC2503FC9DFA03FF05FBF6	Public Domain	No known copyright restrictions apply.

Carapace slightly convex, without clear indication of regions. Front sinuous, marked by 2 slight median emarginations, small median projection between emarginations. Notch between front, inner edge of supraorbital border absent. Supraorbital borders conspicuously bilobed; bordered by raised, finely granular edge, wider, sinuous along front, long setae along expanded distal portion. Suborbital borders granular, each with short, obtuse inner tooth not visible dorsally. Slender, acute tooth on outer orbital angle; smaller, short, narrowly triangular, acute-tipped anterolateral tooth on each side of carapace; carapace border between outer orbital, anterolateral teeth conspicuously tuberculated. Posterolateral borders oblique, nearly straight.</p> <p>Subhepatic, pterygostomial regions, pterygostomial crest, merus, ischium of third maxilliped endopod with short granules.</p> <p>Eye peduncles (Figs 33A; 34) long (1.1 front width), cornea reniform.</p> <p>Chelipeds (P1) (Fig. 34) slightly unequal in males, females; fingers slender, shovel-like, curved, particularly in heavier cheliped of males, slightly shorter than propodus, much shorter in heavier cheliped of males, with blunt teeth, heavier cheliped of males with fewer teeth on dactylus, large cutting edge on fixed finger; no dark colour on fingers.Broad, curved, acute-tipped tooth, row of slender teeth (progressively larger distally) on inner (ventral), proximal margin of carpus, smaller tooth on outer (dorsal), distal margin. Ambulatory legs (P2-P5) (Fig. 34) moderately long, slender; varying number of slender teeth (holotype: 1 on right P2, blunt tooth on left P2, 9 on right P3, 8 on left P3, 14 on right P4, 13 on left P4, 11 on right P5, 14 on left P5), varying number of low tubercles on dorsal margin of meri; varying number of short, slender teeth on dorsal margin of carpi; few long, simple setae along inner, outer margins of meri, carpi, propodi; dactyli long, slender, each with 2 carinae along each side; length of P5 merus 0.9 cl.</p> <p>Male abdomen (Fig. 33C) wide, short, triangular, with 6 freely-movable somites plus telson; telson much wider than long.Somite 3 covers space between P5 coxae, carinated, somite 1 not visible; somite 2 narrower than somite 3, leaving large portion of thoracic sternite 8 visible. G1 (Fig. 33D) short, stout, wide basal part, straight distal part; truncated tip with 2 large, broadly pointed teeth with acute spinules on surfaces.

The many teeth along the dorsal margins of the meri and carpi of the ambulatory legs of the new species and the short, triangular anterolateral teeth (Figs 33B; 34) are in sharp contrast with the single, distal tooth on each of the meri of the ambulatory legs and the well developed, acute anterolateral teeth of N. renoculis n. comb.

Notch between front, inner edge of supraorbital border absent; orbits wide, greatly expanded distally; supraorbital borders conspicuously sinuous; suborbital borders sinuous, without inner tooth; nearly straight lateral borders. Dorsal surface of carapace with slight horizontal ridge, moderately convex, without clear indication of regions. Outer orbital angle with conspicuous, acute, tooth; no anterolateral teeth. Basal antennal article short, distalmost (third) article nearly reaches front. Eye peduncles (Fig. 28C) long, slightly shorter than front (0.8-0.9 front width); cornea strongly reniform, dorso-ventrally flattened, nearly divided into anterior and posterior portions. Anterior border of endostome well demarcated from buccal cavern, ridges faint but clearly defined. Third maxillipeds nearly completely close the buccal cavern. No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete. Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers (Fig. 28C) long, slender, shovel-like, curved, pollex higher than dactylus in large individuals, shorter than elongated propodus; dactylus light in colour, without dark portion; carpus with conspicuous tooth on inner margin. Dorsal margins of ambulatory leg (P2-P5) meri (Fig. 28C) with acute distal tooth; dactyli slender, with carina on each side, non-setose. Male abdomen (Zarenkov 1972, fig. 7-2, as Geneplax [sic] serenei; Chen 1998: fig. 12-5, as Goneplax serenei) with 6 freely-movable somites plus telson, wide, somites 4-6 gradually decreasing in width from somite 3 (widest somite).Telson wide, clearly wider than long. Somite 3 covers space between P5 coxae, somite 2 narrower than somite 3; somites 1, 2 leave large portion of thoracic sternite 8 visible. G1 distally bent in fully grown males but straight in pre-adults (Zarenkov 1972: fig. 7-2, as Geneplax [sic] serenei; Chen 1998: fig. 12-6, 12-7, as G. serenei). G2 (Chen 1998: fig. 12-8, 12-9, as G. serenei) slender, much shorter than G1, flagellum slightly curved, shorter than proximal part (peduncle), pointed tip. Penis arising from P5 coxa, long, soft; broad, soft proximal expansion. Female abdomen with 6 freely-movable somites, wide.Telson much wider than long. Somite 3 covers space between P5 coxae, somite 2 slightly narrower than somite 3; somites 1, 2 leave relatively large portion of thoracic sternite 8 visible. Vulva of mature females not greatly expanded, small, round, extending from 5/6 suture to median portion of thoracic sternite 6, vulvar cover absent, covered by soft membrane leaving anterior margin free.</p> <p>REMARKS</p> <p>Characteristic of Paragoneplax n. gen. is a G2 that is short, much shorter than the G1, in sharp contrast to the G2 of typical goneplacids, where the G2 is about the same length (or slightly longer or slightly shorter in some species) as the G1. The short size of the G2 is very puzzling. A short G2, considered the most derived character (Guinot 1979: 243), is also present in Microgoneplax n. gen. (see description of the new genus below), as well as among most members of the families Euryplacidae Stimpson, 1871, and Pseudoziidae Alcock, 1898, taxa which were once included in the Goneplacidae sensu Balss 1957. The hypothesis that both Paragoneplax n. gen. and Microgoneplax n. gen. should be grouped as a separate subfamily within the Goneplacidae sensu stricto is rejected as the species grouped in these two genera differ in some important characters such as the shape of the G1 (distally bent in Paragoneplax n. gen. but slender and straight in Microgoneplax n. gen.), shape of the male abdomen (unusually broad in Paragoneplax n. gen., more slender in Microgoneplax n. gen.), and the absence of a vulvar cover in Paragoneplax n. gen. (absent in Microgoneplax n. gen.). An alternate hypothesis is to consider both taxa as independent subfamilies, an arrangement that is rejected at this time. In any case, it seems prudent to speculate that a shorter G1 evolved independently among goneplacids.</p> <p>Some additional characters of the new monotypic genus are discussed in the Remarks section for P. serenei n. comb. (see below). Other characters that separate Paragoneplax n. gen. from Goneplax sensu stricto and the five Indo-West Pacific genera that include species that were formerly included in Goneplax sensu lato are summarized in Table 4.</p> </div>	https://treatment.plazi.org/id/102B87CBFFE62507FF57FA85FB7EFB17	Public Domain	No known copyright restrictions apply.

Depth: 53- 280 m.</p> <p>COLOUR</p> <p>A photograph of a freshly collected male from Vanuatu (Santo 2006 expedition; ZRC) shows a light-orange carapace, slightly lighter on the posterior half. The anterior and anterolateral margins of the carapace, as well as a thin, curved band on the cardiac region of the carapace, are dark orange. The chelipeds are light orange with dark orange margins.</p> <p>REMARKS</p> <p>The abundant material from the Philippine Is to Fiji that was examined agrees with the description. Zarenkov’s illustration of the distal part of the G1 (Zarenkov 1972: fig. 7-2, as Goneplax serenei), however, departs from that of the material examined. The tip is shown as broad (almost leaf-like) and bordered by small spines on one side and by short setae on the other. The morphology of the G1 of the specimens examined varies according to size. It is slender in pre-adults (Chen 1998: fig. 12-7, as G. serenei) but uniquely bent distally (Chen 1998: fig. 12-6, as G. serenei). The tip, although often slightly expanded distally has never shown a broad, leaf-like expansion bordered by setae and small spines as that illustrated by Zarenkov 1972. The type material (presumably at ZMMU) could not be examined so this particular character could not be verified. It is possible that Zarenkov’s figure was mislabelled as in some of the other figures in his paper (see Castro 2000: 523, 551).</p> <p>Also characteristic of P. serenei n. comb. are the flattened, shovel-like chelipeds (P1), the absence of anterolateral teeth, and the presence of a distal tooth on the ambulatory leg (P2-P5) meri (Fig. 28C). Also characteristic is an iridescent region at the distal end of the peduncles. It remains visible in specimens that have been preserved for almost thirty years. Other diagnostic characters of the species are given in the description of Paragoneplax n. gen. (see above).</p> </div>	https://treatment.plazi.org/id/102B87CBFFE72504FC80FAE5FC94FA97	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Carapace (Figs 35A; 37; 38A; 39A; Tesch 1918: pl. 10, fig. 2, as Ommatocarcinus orientalis; Takeda &amp; Miyake 1968: fig. 7a, as Goneplax nipponensis; Serène &amp; Umali 1972: fig. 82, as G. ockelmanni) transversely rectangular, much wider than long, relatively wider in larger individuals; widest at conspicuous outer orbital teeth; front slightly deflected ventrally, straight to slightly convex, not marked by median emargination. Notch between front, inner edge of supraorbital border; orbits wide, greatly expanded distally; supraorbital borders conspicuously sinuous, smooth; suborbital borders sinuous, inner tooth short or absent (Tesch 1918: pl. 10, fig. 2a, as O. orientalis); lateral borders sinuous, no anterolateral angle or tooth. Dorsal surface of carapace smooth, moderately convex, without clear indication of regions. Outer orbital angle with conspicuous, outwardly oriented, acute tooth; tooth placed medially or anteriorly on carapace. Basal antennal article short, distalmost (third) article does not reach front. Eye peduncles (Figs 35A; 37; 38A; 39A; Tesch 1918: pl. 10, fig. 2, as O. orientalis; Takeda &amp; Miyake 1968: fig. 7a, as G. nipponensis; Serène &amp; Umali 1972: fig. 82, as G. ockelmanni) long, shorter or longer than front (0.8-1.2 front width); cornea elongated, spherical distal margin, not reniform (not conspicuously dorso-ventrally flattened, not clearly divided into anterior, posterior portions). No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete. Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers (Fig. 37; Tesch 1918: pl. 10, fig. 2 d, as O. orientalis) long, slender, shovel-like, slightly curved (strongly curved in large males), shorter than elongated propodus; dactylus without dark portion; inner (ventral) margin of propodus smooth or with low tubercles in large males; carpus without defined tooth on inner margin; merus with conspicuous tubercles on outer (dorsal) margin, long simple setae. Dorsal margins of ambulatory leg (P2-P5) meri (Fig. 37) unarmed; dactyli of ambulatory legs slender, with carina on each side, setose (P5 propodus, dactylus of S. platypoda n. sp. broad, flat; Fig. 37). Male abdomen (Fig. 36A; Tesch 1918: pl. 10, fig. 2e, as O. orientalis; Serène &amp; Umali 1972: fig. 85, as G. ockelmanni; Serène &amp; Soh 1976: fig. 15A) with 6 freely-movable somites plus telson, wide (more slender in S. styrax n. sp.), somites 4-6 gradually decreasing in width from somite 3 (widest somite). Telson wide, slightly wider than long (slightly longer than wide in S. dichotoma n. sp., S. platypoda n. sp., and S. stryrax). Somite 3 covers space between P5 coxae, somite 2 narrower than somite 3; somites 1, 2 leave small portion of thoracic sternite 8 visible. G1 (Figs 35B; 36B; 38B; 39B; 40A; Takeda &amp; Miyake 1968: fig. 7d-f, as G. nipponensis; Serène &amp; Umali 1972: figs 86, 87, as G. ockelmanni; Serène &amp; Soh 1976: fig. 15B, B’) long, slender, or stout; slightly sinuous, slightly broadened proximally. G2 (Figs 35C; 36C; 38C; 39C; 40B; Tesch 1918: pl. 10, fig. 2 e, as O. orientalis; Serène &amp; Umali 1972: figs 88, 89, as G. ockelmanni; Serène &amp; Soh 1976: fig. 15C) slender, slightly longer than or as long as G1, flagellum longer than proximal part (peduncle); tip curved, pointed, or slightly enlarged with terminal spinule. Penis arising from P5 coxa, moderate size; broad, soft proximal expansion. Female abdomen with 6 freely-movable somites, wide.Telson much wider than long. Somite 3 covers space between P5 coxae, somite 2 slightly narrower than somite 3; somites 1, 2 leave small portion of thoracic sternite 8 visible. Vulva of two mature females reliably identified as belonging to genus (S. styrax n. sp. and S. wolffi) relatively large, extending from edge of suture 5/6 (displaced, arched to make contact with suture 4/ 5 in S. styrax n. sp.; slightly arched in small S. wolffi female) to median portion of thoracic sternite 6, vulvar cover absent.</p> <p>REMARKS</p> <p>Serène &amp; Soh (1976: 17) described their new genus Singhaplax to include two Indo-West Pacific species that did not conform to the description of Goneplax sensu lato: G. nipponesis Yokoya, 1933, and G. ockelmanni Serène, 1971. Guinot (1969b: 522) had previously questioned the inclusion of G. nipponensis (= Singhaplax styrax n. sp.) in the genus Goneplax since its description did not give enough information on the ventral surface. Serène (1971: 915) and Serène &amp; Umali (1972: 82) also commented that S. ockelmanni (as Goneplax ockelmanni) was not congeneric with another species of Goneplax sensu lato (G. sinuatifrons Miers, 1886 = Hadroplax sinuatifrons n. comb.) on account of the structure of their antennules and G1.</p> <p>The discovery of additional species of Singhaplax has provided the opportunity to further characterize the genus. It is nearly identical to Microgoneplax n. gen. in terms of the shape of the carapace but it differs from the latter by the presence of a long G2 that is as long as or slightly longer than the G 1 in contrast to Microgoneplax n. gen., where the G2 is much shorter than the G1 (see description of Microgoneplax n. gen. below). A long G2 was the key character used by Serène &amp; Umali (1972) to define Singhaplax. Other characters that separate Singhaplax from Goneplax sensu stricto and the five Indo-West Pacific genera that include species that were formerly included in Goneplax sensu lato are summarized in Table 4.</p> <p>There are seven described species of Singhaplax, including four being described herein. Two yet undescribed species have been recently discovered in the Philippine Is and will be described jointly with T. Naruse.</p> </div>	https://treatment.plazi.org/id/102B87CBFFE4250AFD61FA65FCABFE0F	Public Domain	No known copyright restrictions apply. See Agosti, D., Egloff, W., 2009.

Carapace convex, without clear indication of regions. Front straight to slightly sinuous. Slight notch between front, inner edge of supraorbital border. Supraorbital borders broad, conspicuously sinuous, smooth, with long simple setae. Suborbital borders conspicuously sinuous, with short, acute granules; short, wide inner tooth not visible dorsally. Long, slender, acute tooth on outer orbital angle; tooth medially placed on carapace. Lateral borders beyond outer orbital teeth slightly curved, no anterolateral teeth.</p> <p>Subhepatic, pterygostomial regions, with low, round tubercles.</p> <p>Eye peduncles (Fig. 35A) long (equal to front width), cornea elongated, spherical distal margin.</p> <p>Chelipeds (P1) unequal (female unknown); fingers slender, dactylus curved, slightly shorter than propodus, with blunt teeth; no dark colour on fingers; inner (ventral) margin of propodus smooth. Broad tooth on inner (ventral), proximal margin of carpus; outer (dorsal) margin of merus with low tubercles, long simple setae. Ambulatory legs (P2-P5) long, slender, unarmed, varying number of long, plumose setae; dactyli long, slender, each with 2 carinae along each side; length of P5 merus 0.8 cl.</p> <p>Male abdomen wide (see abdomen of S. platypoda n. sp., Fig. 36A), with 6 freely-movable somites plus telson; telson slightly longer than wide. Somite 3 covers most of space between P5 coxae; somite 2 only slightly narrower than somite 3, leaving small portion of thoracic sternite 8 visible. G1 (Fig. 35B) long, relatively stout, slightly wider basal part, straight distal part with large denticles; wide, truncated tip with 2 divergent, nearly triangular processes. G2 (Fig. 35C) slender, long, nearly equal or slightly longer than G1, curved flagellum slightly shorter than proximal part (peduncle), tip with terminal spinule.</p> <p>Female unknown.</p> <p>REMARKS</p> <p>The new species is closest to Singhaplax ockelmanni (Serène, 1971). The G1 is bilobed in both species but the apical processes are different. They are large and beak-like in S. ockelmanni (Serène &amp; Umali 1972: figs 86, 87; Serène &amp; Soh 1976: fig. 15B, B’) but they are much smaller in the new species (Fig. 35B). Specimens from the Philippine Is and Indonesia identified here as S. ockelmanni are of the same size range of the type material of S. dichotoma n. sp., which precludes the possibility that the new species represents the pre-adult of S. ockelmanni. Another difference is the G2, with a pointed tip in S. ockelmanni (Serène &amp; Umali 1972: fig. 88; Serène &amp; Soh 1976: fig. 15C) but with a conspicuous terminal spinule in the new species (Fig. 35C). The male telson is different from that of other species of Singhaplax, except S. platypoda n. sp. and S. styrax n. sp., by being slightly longer than wide.</p> </div>	https://treatment.plazi.org/id/102B87CBFFEB2508FF5CFB44FB84FA1A	Public Domain	No known copyright restrictions apply.

Depth: 90 m.</p> <p>REMARKS</p> <p>Ommatocarcinus orientalis Tesch, 1918 is known from only one specimen, the male holotype. It was collected by the Siboga Expedition from the Kai Is, Indonesia (Tesch 1918: 186). The long G2 clearly shown in Tesch’s illustration (Tesch 1918: pl. 10, fig. 2 e, as Ommatocarcinus orientalis), the length of the eye peduncles (much shorter than Ommatocarcinus), the general morphology of the carapace and pereopods, and the small overall size clearly show that Tesch’s species does not belong to Ommatocarcinus but to Singhaplax.</p> <p>Tesch unfortunately did not include the G1 (nor the G2, even if it was illustrated) in the extensive description of his new species. The holotype (ZMA De 103.007) still has the intact G1 even if the abdomen was detached. The G1 is slender and nearly straight, with a scarcely wider proximal part (peduncle). The tip is pointed and acute, and there is a row of small, obtuse denticles along the inner margin of the distal part. The G2, as shown by Tesch (1918: 186, pl. 10, fig. 2e, as O. orientalis), is long and slender and has one terminal spinule.</p> <p>The morphologies of the G1 and G2 plus other characters (narrow male abdomen, absence of a tooth on the median portion of the cheliped meri) demonstrate that S. orientalis, even if known from only one specimen, is distinct from the other four species of Singhaplax (S. dichotoma n. sp., S. platypoda n. sp., S. rhamphe n. sp., and S. styrax n. sp.) plus a similar small-size species (Microgoneplax pelecis n. sp.) that are being described from apparently similar habitats in the Kai Is. These six species of Singhaplax and Microgoneplax n. gen. appear to be sympatric, although it is possible that there are dif- ferences in their particular microhabitats (sediment size, relative position in the sediment) or behaviours (feeding habits, activity patterns, association with other species).</p> <p>Barnard (1950: 286) commented that the small holotype of S. orientalis “appears to be a juvenile”, but his assumption was most probably wrong. The G1 and G2 of the holotype are clearly fully formed.</p> </div>	https://treatment.plazi.org/id/102B87CBFFE82509FD04F9E3FD1CFE30	Public Domain	No known copyright restrictions apply.

They did not examine any material of this species and based their conclusion on observations by Takeda &amp; Miyake (1968). Although the carapace of the specimen illustrated by Takeda &amp; Miyake (1968: fig. 7a) does agree with the characteristic morphology of the carapace and eye peduncles of Singhaplax, the illustration shown in the description of G. nipponensis (Yokoya 1933: fig. 64) does not. The outer orbital teeth in Yokoya’s illustration are much smaller and shorter than in Singhaplax, and the orbits and supraorbital borders are straight instead of the conspicuously sinuous borders of Singhaplax. The type material of Yokoya’s species appears to be lost. His species clearly belongs to a different genus, possibly Hadroplax n. gen. from the general shape of the carapace. Yokoya (1933: 198) actually placed his new species as “near” Goneplax sinuatifrons Miers, 1886 (= Hadroplax sinuatifrons n. comb.).</p> <p>The Japanese material examined and illustrated by Takeda &amp; Miyake (1968), on which Serène &amp; Soh (1976) based their conclusion, belongs instead to S. styrax n. sp. The material examined by Takeda &amp; Miyake, a male and a female, was unfortunately not available for examination but the characteristic G1 of their material (Takeda &amp; Miyake 1968: fig. 7d, e) is identical to that of S. styrax n. sp. (Fig. 39B) with the single exception that the apex is slightly more pointed in the Japanese material than in S. styrax n. sp. The G2 of the male, which was not illustrated by Takeda &amp; Miyake, was described as being longer than the G1 as in S. styrax n. sp. All other characters described by Takeda &amp; Miyake agree with those of the new species.</p> <p>The Taiwan material identified as Goneplax nipponensis by Ho et al. (2004: 659, fig. 6E) appears to be referable to Goneplacoides marivenae (Komatsu &amp; Takeda, 2003) n. comb. (see Remarks for the latter species).</p> <p>Singhaplax styrax n. sp. departs from its other congeners by having a male abdomen that is narrower than in any of the species of Singhaplax where the shape of the abdomen is known, a characteristic of Microgoneplax n. gen. (see below). Another difference is that the supraorbital margins (Fig. 39A) are not as sinuous as in the remaining known species of Singhaplax. The G2 of the new species is nevertheless long in sharp contrast to the short G2 of Microgoneplax n. gen. and the supraorbital margins are smooth in contrast to the granular margins of Microgoneplax n. gen. The outer orbital teeth are more slender than those of its congeners. The teeth are placed slightly more anteriorly on the carapace than in most congeners, where they are more medi- ally placed on the carapace. Also characteristic of the new species are the long plumose setae along the outer (dorsal) margin of the cheliped meri and on the pterygostomial region.</p> <p>The vulva of the only mature female in the material examined (cw 5.6 mm; MNHN-B 30073), and the only mature female reliably identified as belonging to Singhaplax, was round and relatively large. It extended from the edge of suture 5/6, which was uniquely displaced and arched to make contact with suture 4/5, thus appearing as if the anterior edge of the vulva extended from suture 4/5. There was no vulvar cover but the outer posterior margin was slightly thicker than the rest of the margin. The vulva of the second female examined, a pre-adult (cl 3.0 mm, cw 4.6 mm; MNHN-B 30073), was barely visible and suture 5/6 was not displaced or arched.</p> <p>Singhaplax wolffi (Serène, 1964) n. comb.

Depth: 165- 360 m.</p> <p>REMARKS</p> <p>Serène (1964) described Goneplax wolffi from only one specimen, a small incomplete female collected off New Caledonia and illustrated only by a poor photograph (Serène 1964: pl. 16, fig. C). Most of the description consisted of a comparison with Goneplax sinuatifrons (= Hadroplax sinuatifrons Miers, 1886), to which Serène believed it resembled. The description, however, gives two diagnostic characters unique for Singhaplax that were also present in several more recently collected specimens from New Caledonia: a recurved tooth (“une forte épine aigue [sic], longe et courbe”) on the median portion of the inner margin of the cheliped merus, and two small tubercles (“2 très petits tubercules”) at a prominence found at the anterolateral border of the carapace of the holotype (Serène 1964: 192).</p> <p>The examination of the holotype (cl 2.4 mm, cw 4.2 mm; ZMUC 8627) confirmed Serène’s description. The holotype and the additional material from New Caledonia, which includes three males, have permitted a more complete characterization.</p> <p>The G1 (Fig. 40A) has a slender distal part, a pointed tip, and a wide, nearly triangular basal part, with small denticles along the outer border. The G2 (Fig. 40B) is as long as the G1, slender, with a straight flagellum that is about as long as the proximal part (peduncle), and an expanded tip with a terminal spinule. The male abdomen is wide as in the other species of Singhaplax with the exception of S. styrax n. sp. The vulva of the only mature but small female (cw 4.3 mm; MNHN-B 29432) extended from the edge of a slightly arched suture 5/6 to median portion of thoracic sternite 6. There was no evidence of a vulvar cover.</p> <p>Each of the anterolateral borders of the carapace of the largest male (cl 2.6 mm, cw 5.2 mm; MNHN-B 29251) had four small tubercles on a short prominence just posterior to the outer orbital teeth, while there were two in a slightly more pronounced prominence in the small female holotype as indicated by Serène. Two small tubercles were present in a small female (cw 4.3 mm; MNHN-B29432) but the prominence of the holotype was absent. A varying number of tubercles and a prominence on each side of the carapace were found in two small males (cl 2.4 mm, cw 5.0 mm, MNHN-B 29338; cl 2.1 mm, cw 3.5 mm, MNHN-B 29351). There was a small triangular inner tooth on each suborbital border of the holotype as well as in the rest of the specimens that were examined.</p> <p>The cheliped (P1) propodus was short in the holotype and in the small specimens that were examined. It was elongated, however, in the smallest cheliped of the largest male; its largest cheliped was thick and relatively smooth. There were conspicuous tubercles along the inner border of the propodus in the small cheliped of this male. There was a curved tooth on the median portion of the inner margin of the cheliped merus, a character previously indicated for the holotype (Serène 1964: 192). The holotype and the small specimens examined had a small, acute tooth on the inner, distal angle of the carpus. It was missing in the largest male.</p> <p>A relatively large yet sexually immature female from New Caledonia (cl 5.5 mm, cw 9.0 mm; MNHN-B 29366) had two acute teeth on the distal half of the inner margin of the cheliped merus, an acute and conspicuous tooth on the inner margin of the cheliped carpus, and a small tooth only on the posterior angle of the carpus of the left cheliped. The fingers were long and shovel-like, and the dactylus and propodus had long setae on the outer margins. The dorsal surface of the carapace had two shallow ridges and two slight prominences just posterior of each of the outer orbital teeth. The outer orbital tooth was similar to those of Singhaplax but not as prominent. These characters depart so much from those in the holotype and five other specimens of S. wolffi that were examined that it seems certain that they are not conspecific, perhaps not even congeneric.</p> </div>	https://treatment.plazi.org/id/102B87CBFFED2511FF43FCB8FDCEFC54	Public Domain	No known copyright restrictions apply.

Carapace (Figs 41A; 42; 43A; 44A; 45A; 46; Chen 1998: fig. 14-1, as Ommatocarcinus elegans) transversely rectangular, wider than long, relatively wider in larger individuals; widest at conspicuous outer orbital teeth; front slightly deflected ventrally, straight to slightly convex, not marked by median emargination (emargination described in M. elegans n. comb. [Chen 1998: fig. 14-2]). Notch between front, inner edge of supraorbital border. Orbits wide, greatly expanded distally; supraorbital borders conspicuously sinuous, with tubercles; suborbital borders sinuous, with wide inner tooth not visible dorsally. Dorsal surface of carapace smooth, moderately convex, without clear indication of regions. Outer orbital angle with conspicuous, outwardly oriented, acute tooth; tooth medially placed on carapace. Slightly convex lateral borders without anterolateral teeth. Basal antennal article short, distalmost (third) article nearly reaches front. Eye peduncles long (Figs 41A; 42; 43A; 44A; 45A; 46; Chen 1998: fig. 14-1, as Ommatocarcinus elegans), slightly shorter or as long as front (0.7-1.0 front width); cornea elongated, spherical distal margin, not reniform (not conspicuously dorso-ventrally flattened, not clearly divided into anterior, posterior portions). Subhepatic, pterygostomial regions, with low, round tubercles. Anterior border of endostome well demarcated from buccal cavern, ridges faint but clearly defined. Third maxillipeds nearly completely close the buccal cavern. No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against tubercles of pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete. Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers (Figs 42; 46; Chen 1998: figs 14-3, 14-4, as O. elegans) long, slender, shovel-like, curved (conspicuously curved in large males), shorter than elongated propodus; inner (ventral) margin of propodus with large, round tubercles particularly in large males; carpus with blunt tooth on inner margin; merus typically with conspicuous tubercles on outer (dorsal) margin, long simple setae. Dorsal margins of ambulatory leg (P2-P5) meri (Figs 42; 46) unarmed, dactyli slender, with carina on each side. Male abdomen (Fig. 41B) with 6 freely-movable somites plus telson, narrowly triangular (relatively wide in M. elegans n. comb.; see Chen 1998: fig. 14-6, as O. elegans), somites 4-6 gradually decreasing in width from somite 3 (widest somite). Telson longer than wide. Somite 3 covers most space between P5 coxae, somite 2 slightly narrower than somite 3; somites 1, 2 leave large portion of thoracic sternite 8 visible. G1 (Figs 41C; 43B; 44B; 45B; Chen 1998: fig. 14-7, as O. elegans) long, slender, slightly broadened proximally, distal end varies among species. G2 (Figs 41D; 43C; 44C; 45C; Chen 1998: fig. 14-8, as O. elegans) short, less than half G1 length; slightly curved, thick flagellum about same length of proximal part (peduncle), much expanded tip. Penis arising from P5 coxa, moderate size, soft proximal expansion. Female abdomen with 6 freely-movable somites, wide. Telson much wider than long. Somite 3 covers space between P5 coxae, somite 2 slightly narrower than somite 3; somites 1, 2 leave small portion of thoracic sternite 8 visible. Vulva of mature females not expanded, ovoid, extending from 5/6 suture to median portion of thoracic sternite 6, vulvar cover present.</p> <p>REMARKS</p> <p>Microgoneplax n. gen. is being described as a new genus to accommodate the small-size species of Goneplax sensu lato where the G2 is much shorter than the G1, in contrast to Singhaplax where the G2 is longer or as long as the G1. Both genera share the basic morphology of the carapace and pereopods (see Remarks for Singhaplax above). There are, however, some additional differences. The male abdomen is wide (narrow in Singhaplax, except in one species), the front is straight (slightly convex in Singhaplax), the suborbital tooth is conspicuous (short or obsolete in Singhaplax), and the inner (ventral) margin of the P1 merus has conspicuous tubercles (smooth or with short granules in Singhaplax). The outer orbital teeth are always medially placed on the carapace, whereas in some species of Singhaplax they are more anteriorly placed.</p> <p>A short G2, the most derived character (Guinot 1979: 243), is also present in Paragoneplax n. gen., but absent in the remaining members of the Goneplacidae sensu lato. The significance of this character in the suprageneric classification of the Goneplacidae is discussed in the description of Paragoneplax n. gen. (see above).</p> <p>Members of the species of Microgoneplax n. gen. are also characterized by their small size. Males of different species can be distinguished because of their characteristic G1 but females are difficult to identify, particularly if they are pre-adults, do not have a characteristic vulva, or lack both chelipeds (P1). Females have been collected together with males of two different species, so co-occurrence of males and females is not always a reliable way to identify females.</p> <p>Other characters that separate Microgoneplax n. gen. from Goneplax sensu stricto and the five Indo-West Pacific genera that include species that were formerly included in Goneplax sensu lato are summarized in Table 4.</p> </div>	https://treatment.plazi.org/id/102B87CBFFF12516FF5EFC39FC46FBB6	Public Domain	No known copyright restrictions apply.

Depth: 138- 278 m.</p> <p>REMARKS</p> <p>Microgoneplax elegans n. comb. was described from two males collected in the South China Sea and placed in Ommatocarcinus White, 1852. It clearly does not belong to Ommatocarcinus, which is characterized by a G2 that is slender and slightly shorter or longer than the G1, by greatly elongated eye peduncles that may extend well beyond the outer orbital angles, and by much larger adults (see Remarks for Ommatocarcinus below). It belongs instead in Microgoneplax n. gen. on account of a G2 that is much shorter than the G1, eye peduncles that are long but slightly shorter or as long as front and not extending beyond the outer orbital angles, and a small carapace size (cl 4.0-4.3 mm). Characteristic of the species and not found among congeners, however, is a relatively wide male abdomen and a front with a small, pointed prominence (Chen 1998: figs 14-2, 14-6).</p> <p>A male specimen from the Chesterfield Is (cl 5.1 mm, MNHN-B 29316) was tentatively identified as belonging to this species. It shares the wide abdomen and the general morphology of the G1 and G2 with M. elegans n. comb. The ventral view of the G1 is nearly identical to that shown in Chen (1998: fig. 14- 7) except that the setae along the median portion are longer in the Chesterfield Is specimen than the setae shown in the figure.Dorsally, however, the G1 shows a carina-like, crested thickening along its median portion that is not shown in the figure, which unfortunately only shows the ventral surface. Another difference is the front, shown by Chen (1998: fig. 14-2) to have a small median prominence that was not found in the Chesterfield Is specimen. The type material (at IOAS) was not available for examination.</p> </div>	https://treatment.plazi.org/id/102B87CBFFFA251BFF3DFB67FDF9FD51	Public Domain	No known copyright restrictions apply.

Males of species of these two genera can be differentiated because of their G1 and G2. The identification of females, on the other hand, is a difficult task. The vulvae of the four mature females of station DW 29 were all round, without a vulvar cover, and without the displaced suture 5/6 that has been identified in one mature female collected together with the males of S. styrax n. sp. (see above). The inner suborbital tooth was conspicuous (but blunt, not rectangular), which suggests their possible but highly questionable identification as M. pelecis n. sp.</p></div> 	https://treatment.plazi.org/id/102B87CBFFFB2518FF59FD3BFE25FA58	Public Domain	No known copyright restrictions apply.

Somite 3 covers most space between P5 coxae; somite 2 only slightly narrower than somite 3, leaving large portion of thoracic sternite 8 visible. G1 (Fig. 45B) long, slender, thin, slightly wider basal part, sinuous distal part with denticles along inner margin; slender, pointed tip with 2 minute processes.

Vulva of mature females relatively large, oblong, extending from edge of suture 5/6 to median portion of thoracic sternite 6, covered by small, rounded vulvar cover on inner margin plus a small projection on pos- terior margin; thin vulvar cover on enlarged vulva of large females.</p> <p>COLOUR</p> <p>The holotype, which was photographed soon after collection (Fig. 46), was transparent, with a few irregular orange-yellow marking on the carapace and chelipeds.</p> <p>REMARKS</p> <p>The G1 of the new species is similar to that of Microgoneplax elegans n. comb. (see Chen 1998: fig. 14-7, as Ommatocarcinus elegans). In both species the G1 is slender along the entire length without a broad median portion. It is nevertheless straighter and has larger denticles in the new species. A more diagnostic difference between the two species is the much wider male abdomen of M. elegans n. comb. (Chen 1998: fig. 14-6). The outer orbital tooth of M. prion n. sp. is relatively short and nearly triangular (Figs 45A; 46), not as slender as in M. elegans n. comb. and its congeners.</p> <p>An unusually large female (cl 6.4 mm, cw 11.7 mm; MNHN-B 29315) agreed with all of the characters of the species except the vulva. It was large, reminiscent of that of Carcinoplax in its relative size. The vulva was oblong, with square anterior margins, slightly pointed posterior margins, and extending from 5/6 suture to 6/7 suture. Both sutures were slightly displaced, curving around the margins of the vulva. The vulva was covered by a thin, sclerified vulvar cover.</p> </div>	https://treatment.plazi.org/id/102B87CBFFF8251FFF54FA23FECFFDD0	Public Domain	No known copyright restrictions apply.

Wide notch between front, inner edge of supraorbital border; orbits wide, greatly expanded distally; supraorbital borders sinuous, concave; suborbital borders slightly sinuous, with wide, obtuse inner tooth not visible dorsally; anterolateral borders convex. Dorsal surface of carapace smooth or conspicuously granular, with slight horizontal ridges, moderately convex, without clear indication of regions. Outer orbital angle with conspicuous, acute tooth; anterolateral tooth absent (obtuse prominence in O. fibriophthalmus Yokoya, 1933). Basal antennal article short, distalmost (third) article reaches front. Eye peduncles long, much longer than front (at least 3 times front width); cornea elongated, not reniform (not conspicuously dorso-ventrally flattened, not clearly divided into anterior and posterior portions). Stridulating mechanism of rubbing proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete. Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers long, slender, slightly curved, shorter than elongated propodus; varying portion of fingers may be darker in colour, tip light; carpus with broad tooth on inner margin (merus with median tooth in O. macgillivrayi).

Depth: subtidal to 100 m (Poore 2004).</p> <p>REMARKS</p> <p>Ommatocarcinus macgillivrayi has often been confused with O. pulcher Barnard, 1950 (see Remarks for this species below), and many if not all records of O. macgillivrayi from Japan appear to be referable to O. pulcher. Illustrations and photographs given by Sakai (1935: fig. 96; 1939: pl. 102, fig. 5; 1976: pl. 188, fig. 5), Kamita (1963: fig. 4), Miyake (1991: pl. 50, fig. 5), and Ikeda &amp; Takeda (2006: fig. 2G) show that the eye peduncle extends slightly beyond the outer orbital teeth (or should extend, in illustrations and photographs where the peduncles are extended anteriorly), a characteristic of O. pulcher. In contrast, only the distal margin of the eye itself slightly extends beyond the outer orbital teeth in O. macgillivrayi. The eye-peduncle length in relation to frontal length, however, is similar in both species, varying between 3.3 and 3.4 front width. A more reliable character is the acute tooth present on the distal portion of the meri of the ambulatory legs (P2- P5) that is diagnostic for O. macgillivrayi. It is absent in all of the Japanese specimens shown in the literature. The tooth is small, however, and it may not show in photographs. In some specimens it may be missing in some (but not in all) of the legs. Nevertheless, a Japanese specimen previously identified as O. macgillivrayi by T. Sakai (BMNH 1961.6.5.85) belongs indeed to O. pulcher. Other Japanese specimens, however, must be properly identified to settle the question.</p> <p>The presence of O. macgillivrayi in New Zealand is also questionable. Neommatocarcinus huttoni (Fig. 51), which is known only from New Zealand, has been confused with O. macgillivrayi so that the New Zealand records of this species where the specimens in question have not been examined are assumed to belong to N. huttoni. Differences between these two species are discussed in the Remarks section of N. huttoni (see below) and by Takeda &amp; Miyake (1969b: 179).</p> </div>	https://treatment.plazi.org/id/102B87CBFFFC251DFF33FC3AFBE2FDD0	Public Domain	No known copyright restrictions apply.

Depth: 107 m.</p> <p>REMARKS</p> <p>Male specimens and additional material of O. granulatus, which is known only from the female holotype from the South China Sea, should be examined and compared to the other known species of Ommatocarcinus. The illustration and English description by Chen (1998: 312, fig. 13), however, show clear differences from O. fibriophthalmus: absence of anterolateral teeth or prominences, a wider carapace, and the presence of a small distal tooth on the meri of each of the ambulatory legs (P2-P5). These characters, however, are also present in O. macgillivrayi, and Chen (1998: 313) contrasts her new species with O. pulcher Barnard, 1950 but not with O. macgillivrayi. Ommatocarcinus granulatus can be differentiated from O. macgillivrayi by the relative length of their eye peduncles. The peduncles extend a considerable distance, about a third of its total length, beyond the outer orbital teeth in O. granulatus (Chen 1998: fig. 13-1) but only the distal margin of the eye itself extends beyond the outer orbital teeth in O. macgillivrayi. The cheliped (P1) merus has small teeth along the dorsal border and another small tooth on the distal border of the cheliped in O. granulatus (Chen 1998: fig. 13-4), in contrast to a large obtuse tooth on the median portion of the outer (dorsal) margin of the merus in O. macgillivrayi. The carapace is noticeably narrower in O. granulatus: “1.82-1.86 times as broad as long” (Chen 1998: 313) but wider, carapace width 2.3 times carapace length, in O. macgillivrayi.</p> </div>	https://treatment.plazi.org/id/102B87CBFF0225E2FF22FDDDFB82FE4E	Public Domain	No known copyright restrictions apply.

Depth: shallow subtidal to at least 100 m.</p> <p>REMARKS</p> <p>Ommatocarcinus pulcher was described from one large (cl 15 mm, cw 37 mm) male specimen collected from a fish stomach in South Africa (Barnard 1950: 286, fig. 53 b-f). The holotype could not be examined during this study but the description and detailed illustrations (including the G1) in Barnard’s description are clear and reasonably complete. The species is close to O. macgillivrayi, in terms of the shape of the carapace (anterolateral teeth are absent) and a similar G1. Takeda &amp; Miyake (1969b: 174) had suggested that it was a synonym of White’s species. One difference, however, is that the eye peduncles extend slightly beyond the outer orbital teeth in O. pulcher (Dai &amp; Yang 1991: pl. 55, fig. 3), whereas in O. macgillivrayi only the distal margins of the eyes, not the eye peduncles, extend beyond the teeth (Dai &amp; Yang 1991: pl. 55, fig. 2, as O. macgillivaryi [sic]). Other differences are the absence of the small distal tooth on the merus of each of the ambulatory legs (P2-P5) and of the median tooth on the cheliped merus that are characteristic of O. macgillivrayi. The G1 of O. pulcher is slightly less pointed than that of O. macgillivrayi (see Dai &amp; Yang 1991: figs 199-1, 199-2; Hsueh &amp; Huang 2002: figs 3F, G). The stridulating ridge on the proximal edge of the outer (dorsal) margin of the cheliped merus (Barnard 1950: fig. 53 e; Dai &amp; Yang 1991: fig. 199-3) is less pronounced in O. pulcher than in O. macgillivrayi although the difference may be due to size since only large specimens of the latter were examined.</p> <p>The Japanese records of O. macgillivrayi appear to be referable to O. pulcher (see Remarks for O. macgillivrayi above). Ommatocarcinus sp. (Yokoya 1933), known from three Japanese specimens that could not be examined, also appears to represent O. pulcher since the meri of the ambulatory legs are similarly unarmed (Yokoya 1933: 198, fig. 65). Material from Vietnam identified by Zarenkov (1972: 234, fig. 1-2) as “ Ommatocarcinus sp. Yokoya?” could not be examined or identified by the information provided.</p> </div>	https://treatment.plazi.org/id/102B87CBFF0225E3FD6AFE3CFE4BF97C	Public Domain	No known copyright restrictions apply.

Slight notch between front, inner edge of supraorbital border; orbits wide distally to accommodate reniform eyes, supraorbital borders conspicuously sinuous; suborbital borders rounded, with conspicuous, blunt inner tooth not visible dorsally; anterolateral borders straight or nearly straight so that fronto-orbital border as wide as or slightly narrower than maximum width of carapace at junction of anterolateral, posterolateral borders. Dorsal surface of carapace smooth, slightly convex, without clear indication of regions. Outer orbital teeth strongly projecting outwardly, flattened, triangular or leaf-like; typically acute anterolateral tooth on each side of carapace. Basal antennal article short, slender, distalmost (third) article reaches front. Eye peduncles relatively short, much shorter than front (0.3-0.4 front width); eyes reniform, dorso-ventrally flattened, cornea greatly expanded distally, nearly divided into anterior, posterior portions. Stridulating mechanism of subocular, sinuous pterygostomial crest plus tooth on outer (dorsal) margin of cheliped (P1) merus. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6 interrupted medially, 6/7 almost complete, 7/8 complete (Fig. 47; Guinot &amp; Richer de Forges 1981b: fig. 12D; 1990: fig. 24). Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers (Guinot 1990: figs 1-3, 19-23, 29-33, 35-38, 40) slender, shorter than propodus, not dark in colour; carpus with tooth on inner margin. Dorsal margin of merus of P2 (Guinot 1990: figs 4-9, 41-43) with 1 subdistal tooth; dorsal margins of meri of P3-P5 (Guinot 1990: figs 26-28, 34, 39) with several conspicuous, acuminate teeth; dorsal margins of carpi, propodi serrulated, with conspicuous teeth, or smooth; dactyli slender, carinated, setae absent. Male abdomen (Guinot 1990: fig. 24; Hsueh &amp; Huang 2002: fig. 12C) with 6 freely-movable somites plus telson, triangular, relatively wide, somites 4-6 gradually decreasing in width from somite 3 (widest somite). Telson wider than long. Somite 3 covers space between P5 coxae, somite 2 longer than somite 3 so that somites 1, 2 leave small, often triangular portion of thoracic sternite 8 visible (Guinot &amp; Richer de Forges 1981b: fig. 12D; Guinot 1990: fig. 24; Hsueh &amp; Huang 2002: fig. 12G). G1 (Zarenkov 1972: fig. 6-5; Guinot &amp; Richer de Forges 1981b: fig. F; Guinot 1990: figs 44, 45, 47, 48, 50, 52, 53; Hsueh &amp; Huang 2002: fig. 12D, H) long, stout, sinuous, proximally broadened, nearly triangular in overall shape, truncated tip.

G; Guinot 1990: figs 46, 49, 51, 54) slender, slightly longer than G1, flagellum slightly shorter than basal part, with basal spinules, slightly-expanded tip. Penis arising from P5 coxa, long, soft; narrow, soft proximal expansion. Female abdomen (Hsueh &amp; Huang 2002: fig. 12E) with 6 freely-movable somites, wide. Telson subovate. Somite 3 covers space between P5 coxae, somite 2 narrower than somite 3 so that somites 1, 2 leave small, often triangular portion of thoracic sternite 8 visible. Vulva of mature females (Fig. 47) on margin of suture 5/6 posterior to large, oval depression on thoracic sternite 5; small, hook-like vulvar cover on posterior margin of vulva.</p> <p>REMARKS</p> <p>Alcock (1899: 73) commented on the close similarities between Psopheticus and Carcinoplax H. Milne Edwards, 1852, adding that the genus should “perhaps ought rather to be regarded as a subgenus of Carcinoplax ”. Serène (1968: 90) included Psopheticus in a list of genera questionably included in the subfamily Carcinoplacinae. Guinot (1990) revised Psopheticus and recognized seven species, including four new ones. Števčić (2005) placed Psopheticus sensu lato in the tribe Psopheticini independent from the tribe Carcinoplacini of the subfamily Carcinoplacinae. Psopheticus sensu lato actually consists of two groups of different species as far as the reproductive structures are concerned. A new genus, Exopheticus n. gen., is erected herein to include one of the two groups.</p> <p>Species of Psopheticus possess a conspicuous soundmaking, or stridulating, mechanism that consists of a pterygostomial crest on inflated subocular and subhepatic regions that rubs against a large tooth on the distal margin of the P1 merus (see Alcock 1900: 309; Guinot 1990: 364, figs 55-57; Guinot- Dumortier &amp; Dumortier 1960). The mechanism is found in both sexes and its function remains unknown.</p> <p>Psopheticus megalops Takeda, 1989, which was described from Japan, clearly does not belong in Psopheticus or in Exopheticus n. gen. Its inclusion in Psopheticus by Takeda (1989: 174) was based on “rather arbitary [sic] and tentative” reasons, mostly on the quadrate shape of its carapace. The morphology of its pointed G1 and G2 (Takeda 1989: fig. 17C-F) suggests its exclusion from the Goneplacidae sensu stricto.</p> <p>KEY TO SPECIES OF PSOPHETICUS WOOD- MASON, 1892</p> <p>1.

Depth: 284- 785 m. Also collected from a station at a depth of 720-900 m (Tesch 1918: 161).</p> <p>REMARKS</p> <p>The relatively large number of specimens of P. stridulans examined has permitted the study of individual variation. Guinot (1990) used the presence of a single dorsal, subdistal tooth in each P2 merus as a diagnostic character of the species. Nevertheless, one of the three topotype specimens, a female, was shown to actually have two teeth, the second being small and almost median (Guinot 1990: fig. 4). There is a great deal of variation in the ornamentation of the ambulatory legs (P2-P5). Most specimens had one dorsal, subdistal tooth on each P2 meri but there were some exceptions. A pre-adult female from Indonesia (cl 8.1 mm, cw 10.2 mm, MNHN-B 29173) had three teeth on the right leg and two (plus a short one) on the left leg. The carpus of the right P5 showed one tooth while that of the left P5 had one tooth and five short ones, which may categorize it as “spinulose,” another diagnostic character of the species. Another exception was a large male also from Indonesia (cl 24.8 mm, cw 31.7 mm, MNHN-B 29175) with three teeth on each P2 merus. One small male from the same station (cl 11.8 mm, cw 15.0 mm, MNHN-B 29175) had two teeth on each P2 merus while a small female (cl 10.9 mm, cw 14.5 mm, MNHN-B 29175) had one tooth on the right merus but two on the left one. Two females (cl 23.8 mm, cw 29.2 mm, cl 23.8 mm, cw 29.8 mm; MNHN-B 29168) had three dorsal teeth on each P2 merus.</p> <p>Revision of Goneplacinae (Crustacea, Brachyura)</p> <p>The P3-P5 carpi typically showed two teeth. In several small specimens (male, cl 16.1 mm, cw 19.9 mm, MNHN-B 29170), however, the P4 carpi showed one large tooth and several smaller ones. Two females (cl 23.8 mm, cw 29.2 mm, cl 23.8 mm, cw 29.8 mm; MNHN-B 29168) showed the same ambulatory leg ornamentation, three dorsal teeth on P2, as P. insolitus Guinot, 1990, from Indonesia, which was described from only one female specimen from Indonesia.</p> <p>All of the specimens with exceptions described above showed the acute, slender anterolateral teeth and the broad, triangular outer orbital teeth that characterize the species. Psopheticus insolitus was described as a separate species because of its unusual ambulatory leg ornamentation, a situation that has also been found in specimens of P. stridulans. The anterolateral teeth of the holotype of P. insolitus, however, are unusually blunt (Guinot 1990: fig. 40) in contrast to the acuminate ones of P. stridulans. Since the shapes of the outer orbital and anterolateral teeth are seemingly more stable characters than the ornamentation of the ambulatory legs, the morphology of the single specimen of P. insolitus is still puzzling. It is felt, however, that there are no clear, valid reasons to consider it a member of a separate species.</p> <p>As pointed out by Guinot (1990: 337), specimens from Japan (Sakai 1955: 108, fig. 2; 1976: 530, pl. 193, fig. 3) and the South China Sea (Zarenkov 1972: 231, figs 2, 6-5) identified as P. stridulans do not belong to this species but to P. musicus Guinot, 1990, on account of the smooth, unarmed carpi and propodi of the ambulatory legs. A figure given by Sakai (1955: fig. 2), however, does show teeth on the right P3-P4 and the left P3 but none are shown in another specimen (Sakai 1976: pl. 193, fig. 3). No teeth are shown in illustrations of other specimens from Japan (Ikeda 1998: 138, pl. 58) and Taiwan (Hsueh &amp; Huang 2002: figs 8E, 12). The presence of P. musicus in Japan and Taiwan has now been confirmed (see below) but not that of P. stridulans.</p> <p>The vulva of mature females (Fig. 47) has a small, hook-like vulvar cover on its posterior margin.</p></div> 	https://treatment.plazi.org/id/102B87CBFF0325E7FD61FF31FD80FE10	Public Domain	No known copyright restrictions apply.

Depth: 300- 510 m.</p> <p>REMARKS</p> <p>Psopheticus crosnieri is closest to P. musicus. The outer orbital teeth of P. crosnieri are oriented outwardly and are typically much more slender and spiniform, and the anterolateral teeth similarly more slender (Guinot 1990: figs 29, 31, 33) than in P. musicus (Guinot 1990: figs 35, 37, 38). These characters, however, may vary among some specimens (see below). Another difference is that the P3-P5 carpi are feebly serrulated (but not to the naked eye) in P. crosnieri but smooth in P. musicus. Differences in the shape of the third maxilliped merus mentioned by Guinot in her key (Guinot 1990: 334) were found to be unsubstantiated.</p> <p>Six specimens from la Réunion, southwestern Indian Ocean, identified as Psopheticus aff. stridulans by Guinot (1990) should be placed under P. crosnieri on account of their slender outer orbital and anterolateral teeth (Guinot 1990: fig. 2), even if the P3-P5 carpi may be armed with one or two teeth (none or one in P3, one or two in each P4 and P5; Guinot 1990: figs 7-9) but unarmed in P. crosnieri. The shape of the teeth on the carapace of Psopheticus is a much more stable character (even though not absolute, see Remarks for P. musicus below) than the ornamentation of the ambulatory legs, which may vary widely (see Remarks for P. stridulans above).</p> </div>	https://treatment.plazi.org/id/102B87CBFF0725E7FF00FDFDFB49FC14	Public Domain	No known copyright restrictions apply.

Depth: 190- 521 m. Sakai (1976) reports it (as P. stridulans), from depths of 75-150 m and Zarenkov (1972: 231) lists it (as P. stridulans) at a questionable depth of 925 m. Specimens were also obtained from tangle nets of local fishermen in the Philippines that obtained material from at least an estimated depth of 50 m.</p> <p>REMARKS</p> <p>Diagnostic of P.musicus are smooth, unarmed P3-P5 carpi and propodi as observed with the naked eye. In most specimens the outer orbital teeth are triangular, foliaceous, and straight, and the anterolateral teeth are relatively short and triangular, not conspicuously slender (Guinot 1990: figs 35, 37, 38). The shape and relative size of the outer orbital and anterolateral teeth, however, may vary as in other species of Psopheticus. Two of the characters used by Guinot (1990) to separate P. musicus from P.crosnieri, which is known only from Madagascar and la Réunion (outer orbital tooth that is oriented outwardly, anterolateral tooth that is slender, or spiniform, in P. crosnieri) were observed in a few of the specimens collected in Bohol, Philippine Is.</p> </div>	https://treatment.plazi.org/id/102B87CBFF0725E4FD49FBE6FBE0FB37	Public Domain	No known copyright restrictions apply.

Depth: 300- 700 m.</p> <p>COLOUR</p> <p>Photographs of a freshly collected male specimen from New Caledonia (MNHN-B 29322) and a female from Fiji (MNHN-B 29202) showed a light orange anterior half of the carapace divided from the white posterior half by two thin bands, one dark orange and the second white. The ambulatory legs were pinkish white. This colour pattern is similar to that given by Ikeda (1998: 138, pl. 58, as P. stridulans) for P. musicus.</p> <p>REMARKS</p> <p>Diagnostic to the species is the presence of small teeth along the P3-P5 carpi and propodi (Guinot 1990: figs 26-28), in contrast to a close species, P. stridulans, where the teeth are absent in the propodi, at least to the naked eye (Guinot 1990: figs 4-6). Other than the ornamentation of the ambulatory legs, the characters given by Guinot (1990: 348) to separate both species are not always consistent. The triangular outer orbital teeth and the relatively short and triangular anterolateral teeth of P. vocans are also characteristic of P. musicus. In contrast to P. musicus, however, the P3-P5 carpi and propodi of P. vocans are always dentate, at least one member of a particular pair of legs.</p> <p>As in other species of Psopheticus, there is much variation in the ornamentation and on the development of teeth on the ambulatory legs. Some of the observed variation was between the right and left members of the same pair of ambulatory legs. A male (cl 22.6 mm, cw 28.4 mm, MNHN-B 29179) had a smooth P2 right merus (the characteristic dorsal, subdistal tooth on the left P2) and a relatively smooth (almost microscopic teeth) P3 right propodus, but there were well developed teeth on the left P3.</p> <p>Three of nine specimens from Fiji (female, cl 20.6 mm, cw 27.6 mm, MNHN-B 29202; male, cw 25.3 mm, MNHN-B 29199; ovig. female, cl 20.3 mm, cw 25.0 mm, MNHN-B 29177) had two dorsal teeth on the P2 merus instead of one. Each of the P2 carpi of these specimens had a tooth that was smaller than in the typical specimens. The ornamentation of P3-P 5 in these three specimens was similar to the remaining specimens except that the teeth on the propodi were smaller. The P3-P5 carpi of the three males from Tonga (cl 17.9 mm, cw 23.5 mm, cl 12.7 mm, cw 17.2 mm, cl 12.4 mm, cw 16.8 mm; MNHN-B 29256), however, had one well developed tooth and many small teeth. There were no important differences in the shape and ornamentation of P1 and P2, carapace, G1, G2, and the relative length of the ambulatory legs (P2-P5) between the Fiji and Tonga specimens on one hand and those of P. vocans from New Caledonia, including the holotype (MNHN-B 6805) and paratype (MNHN-B 10531). The P3-P5 meri of the Tonga specimens are similar to those of P. insolitus Guinot, 1990 (= P. stridulans Wood-Mason, 1892), which was described from one specimen from Makassar Strait, Indonesia, and of a small female from New Caledonia (cl 10.4 mm, cw 14.2 mm; MNHN-B 29281) in having one well developed tooth and many small ones. The P2 merus, however, had three teeth in P. insolitus instead of the single tooth in P. vocans and the Tonga and New Caledonia specimens. It thus seems that the observed variations in the Fiji and Tonga specimens are part of the normal morphological variation of P. vocans. These specimens are treated here as members of populations of what appears to be the extreme eastern limit of the distribution of P. vocans rather than as a different species.</p> </div>	https://treatment.plazi.org/id/102B87CBFF0425EAFD42FAC5FDD7FB57	Public Domain	No known copyright restrictions apply.

Eye peduncles (Fig. 48A; Guinot 1990: figs 10-12, as P. insignis; fig. 17, as P. hughi; Chen 1998: fig. 7-1, as P. insignis) relatively short to moderately long (0.2-0.5 front width; Fig. 48A; Guinot 1990: figs 10-12, as P. insignis; fig. 17, as P. hughi; Chen 1998: fig. 7-1, as P. insignis), shorter than front; eyes reniform, dorso-ventrally flattened, cornea greatly expanded distally. Anterior border of endostome well demarcated from buccal cavern, ridges faint but clearly defined. Third maxillipeds completely close the buccal cavern. Stridulating mechanism of subocular, elliptical pterygostomial crest rubbing against proximal portion of cheliped (P1) merus. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete (Figs 49; 50; Guinot 1990: fig. 16, as P. insignis). Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers (Guinot 1990: figs 10-12, as P. insignis, figs 17, 18, as P. hughi; Chen 1998: fig. 7- 2, as P. insignis) slender, shorter than propodus, dark in colour (light colour in E. hughi n. comb.); carpus with tooth on inner margin; merus becomes greatly elongated with size (Guinot 1990: figs 11, 12) in E. insignis n. comb. Dorsal margin of merus of P2 (Guinot 1990: fig. 17, as P. hughi) with subdistal tooth (may be obsolete in E. insignis n. comb.); dorsal margins of meri of P3-P5 (Guinot 1990: figs 10-12, as P. insignis, fig. 17, as P. hughi) with subdistal tooth (may be obsolete in large specimens); dorsal margins of carpi, propodi of ambulatory legs (P2-P5) smooth; dactyli slender, smooth (carinated in small specimens), setose. Male abdomen (Fig. 48B; Chen 1998: fig. 7-5, as P. insignis; Hsueh &amp; Huang 2002: fig. 13H, as P. hughi, fig. 14E, as P. insignis) with 6 freely-movable somites plus telson, relatively wide, somites 4-6 gradually decreasing in length from somite 3 (widest somite). Telson wider than long. Somite 3 covers space between P5 coxae; somite 2 much longer than somite 3 so that somites 1, 2 leave large, subquadrate to rectangular portion of thoracic sternite 8 visible in E. insignis n. comb. (Hsueh &amp; Huang 2002: fig. 14C, as P. insignis; small triangular portion in E. hughi n. comb.); somite 1 mostly covered by carapace. G1 (Fig. 48C; Guinot 1990: figs 13, 14; Chen 1998: fig. 7-6, as P. insignis; Hsueh &amp; Huang 2002: fig.13D, as P. hughi, fig. 14F, as P. insignis) long, slender, sinuous, only slightly broadened proximally, truncated tip. G2 (Fig. 48D; Guinot 1990: fig. 15; Chen 1998: fig. 7-7, as P. insignis) slender, nearly equal or slightly longer than G1, flagellum slightly shorter than basal part, with basal spinules, slightly-expanded tip. Penis arising from P5 coxa, long, soft; wide, soft proximal expansion. Female abdomen with 6 freely-movable somites, wide. Telson subovate (Hsueh &amp; Huang 2002: fig. 13I, as P. insignis). Somite 3 covers space between P5 coxae, somites 1, 2 slightly narrower than or as wide as somite 3, only small portion or no portion at all of thoracic sternite 8 visible. Vulva of mature females (Figs 49; 50) round, extending to sutures 5/6 and 6/7 of thoracic sternite 6, covered by soft membrane; vulvar cover absent.</p> <p>REMARKS</p> <p>Exopheticus n. gen. includes two species previously included in Psopheticus, as P. hughi Rathbun, 1914, and P. insignis Alcock, 1900. According to Alcock (1900: 311) Psopheticus insignis “closely connects” Psopheticus and Carcinoplax H. Milne Edwards, 1852. Serène &amp; Vadon (1981: 127) had also commented on the sharp differences (“totalement différent”) between the G1 of E. insignis n. comb. (as Psopheticus insignis Alcock, 1900), similar to that of Carcinoplax, and the G1 of its congener, P. stridulans. They also commented on the similarities between the carapace and chelipeds (P1) of E. insignis n. comb. and those of some species of Carcinoplax, particularly C. longimana (de Haan, 1833). Guinot (1969b: 528) remarked on the need of establishing a diagnosis for Psopheticus in order to determine if P. insignis and P. hughi belonged to the same genus as P. stridulans. Unfortunately, her revision of Psopheticus (Guinot 1990) did not include a diagnosis. Such a diagnosis would have undoubtedly demonstrated the peculiarities of P. insignis and P. hughi on one hand and P. stridulans (and three other species of Psopheticus sensu lato) on the other, with their subsequent separation as different genera.</p> <p>Exopheticus n. gen. is characterized by a slender G1 (Fig. 48C; Guinot 1990: fig. 13; Chen 1998: fig. 7-6, as P. insignis) in contrast to a stout G1 with a broad, nearly triangular proximal part in Psopheticus (Zarenkov 1972: fig. 6-5; Guinot &amp; Richer de Forges 1981b: fig. F; Guinot 1990: figs 44, 47, 50, 52). The vulva (Figs 49; 50) is large, extending between sutures 5/6 and 6/7 of thoracic sternite 6, with smooth margins lacking a vulvar cover, and covered by a soft membrane. This condition is in contrast to Psopheticus, where the vulva is much smaller, extending only along the margin of suture 5/6, in a large depression on thoracic sternite 5, and bordered on the posterior edge by a hook-like vulvar cover (barely visible in Fig. 47). The carapace is subcircular in Exopheticus n. gen. (subquadrate in Psopheticus), the dorsal margins of P3-P5 have only one distal tooth (Chen 1998: fig. 7-4, as P. insignis) but several teeth in Psopheticus, the first and second somites of the male abdomen leave a large subquadrate portion of thoracic sternite 8 visible (only a small triangular portion remains visible in Psopheticus and in E. hughi n. comb.; Guinot &amp; Richer de Forges 1981b: fig. 12D; Guinot 1990: fig. 24, as P. insignis), and the inner margin of the suborbital border is only marked by a short tooth not visible dorsally in larger individuals (conspicuous tooth in Psopheticus). The stridulating mechanism of Exopheticus n. gen. appears to involve only the rubbing of the cheliped merus against the subhepatic surface of the carapace (Guinot 1990: figs 58-60, as P. insignis and P. hughi) whereas teeth in the merus appear to be involved in Psopheticus (Guinot 1990: figs 55-57).</p> <p>In comparing her new species, P. hughi, with P. stridulans and P. insignis (= E. insignis n. comb.), Rathbun (1914: 145) mentioned that in the latter two species the first and second somites of the male abdomen do not cover the thoracic sternites as in the holotype of P. hughi (USNM 46180), the only specimen she apparently examined. Practically all the male specimens of E. hughi n. comb. that were examined during this study, however, showed that the first and second somites leave a small triangular area of the thoracic sternite 8 exposed as in the species of Psopheticus and unlike E. insignis n. comb., where a much larger, square to rectangular portion is left exposed. In some small specimens of E. hughi n. comb., however, an even smaller portion of the sternum is left exposed. The drawing of the posterior portion of the abdomen of E. hughi n. comb. in Hsueh &amp; Huang (2002: fig. 13C, as Psopheticus hughi) is unfortunately not clear as to which portions of the thoracic sternum are left exposed.</p> <p>In contrast to Psopheticus, Exopheticus n. gen. shares with Carcinoplax the structure of its G1, G2, and vulva. Exopheticus n. gen. is nevertheless distinguished from Carcinoplax in that its thoracic suture 6/7 is complete (interrupted medially in Carcinoplax), the first and second somites of the male abdomen leave a large subquadrate portion of thoracic sternite 8 visible (only a small portion of the thoracic sternite is visible in Carcinoplax), the orbits are wide distally to accommodate the reniform eyes (orbits not expanded and the cornea of the eyes are rounded in Carcinoplax), the supraorbital borders are sinuous (only slightly curved in Carcinoplax), there is an obvious, specialized stridulating mechanism (absent in Carcinoplax), and the dorsal margin of the carpi and propodi of the P3-P5 have a subdistal tooth (absent in Carcinoplax, except C. spinosissima Rathbun, 1914).</p> </div>	https://treatment.plazi.org/id/102B87CBFF0A25E8FF4EFB27FCBDFC74	Public Domain	No known copyright restrictions apply.

A; McLay 1988: fig. 58a) transversely rectangular, much wider than long, widest at conspicuous outer orbital teeth; front narrow, deflected ventrally, slight median projection (Takeda &amp; Miyake 1969b: fig. 5a). Dorsal surface of carapace granular, convex, without clear indication of regions. Anterolateral teeth absent. Wide notch between frontal margin, inner edge of supraorbital border. Orbits wide, greatly expanded distally, fissure absent. Eye peduncle (Fig. 51; Takeda &amp; Miyake 1969b: pl. 2, fig. A; McLay 1988: fig. 58) long, much longer than front (1.4-1.6 front width), eyes beyond outer orbital tooth; cornea elongated, spherical distal margin, not reniform. Supraorbital borders convex, slight subproximal lobe; suborbital borders sinuous, with large, keel-like inner tooth; lateral borders convex; anterolateral tooth absent. Basal antennal article short, subcylindrical, distalmost (third) article reaches front, lying freely in orbital hiatus, not reaching front. Antennules not separated by septum. Buccal cavern narrow anteriorly, strongly crested. No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete. Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Prolongation of male episternite 7 present; thoracic sternite 7 laterally covered with thoracic sternite 8; thoracic sternite 8 without supplementary plate. Chelipeds (Fig. 51; Takeda &amp; Miyake 1969b: fig. 5b; McLay 1988: fig. 58) larger in males; fingers long, slender, slightly curved, light in colour, shorter than elongated propodus; carpus with broad tooth on inner (ventral) margin, acute tooth on outer (dorsal) margin; merus with 3 or 4 long, acute teeth on distal, outer (dorsal) margin (short, obtuse in large specimens); short, acute tooth on each median portion of inner (ventral), outer (dorsal) margins. Ambulatory legs (P2-P5) (Fig. 51) compressed, dorsal margins of meri with acute distal tooth (obsolete in large individuals), row of tubercles increasing in size distally, sometimes acute; dactyli slender, dorso-ventrally flattened, with slight carina on each side, setose. Male abdomen (Takeda &amp; Miyake 1969b: fig. 6a) narrowly triangular, narrower than sternum, somites 3-5 being narrower than thoracic sternite 7; with 4 freely-movable somites (somites 3-5 fused) plus telson, shallow carina along widest, proximal portion of fused somites 3-5. Telson slightly wider than long, rounded anterior margin. Posterior border of somites 3-5 (carinated portion) covers space between P5 coxae, somite 2 much narrower than somites 3-5 so that somites 1, 2 leave large portion of thoracic sternite 8 visible (Takeda &amp; Miyake 1969b: fig. 6a). Locking mechanism with medium-size vulvar cover on edge of thoracic sternite 5, shallow socket on underside (ventral surface) of abdominal somite 6. Male opening coxal. Penis arising from P5 coxa, sclerified portion between thoracic somites 7, 8 before soft portion (Takeda &amp; Miyake 1969b: fig. 6b). G1 (Takeda &amp; Miyake 1969b: fig. 5d) long, slender, thin, nearly straight, only slightly broadened proximally; pointed, thin tip. G2 slender, longer than G1, flagellum shorter than proximal part (peduncle); curved, pointed tip. Female abdomen with 6 freely-movable somites, wide.Telson much wider than long. Somite 2 covers most space between P5 coxae, somite 2 narrower than somite 3 but somites 1, 2 leave relatively large portion of thoracic sternite 8 visible. Vulva of mature females ovoid, on large, sclerified prominence extending from deflected 5/6 suture to close to 6/7 suture, covered by soft membrane, vulvar cover absent.</p> <p>REMARKS</p> <p>Takeda &amp; Miyake (1969b) separated Ommatocarcinus huttoni (Filhol, 1885) from the other known species of Ommatocarcinus by creating a new genus, Neommatocarcinus, on account of several unique characters. The male abdomen has only four somites plus telson, somites 3-5 being fused. This is unique among members of the family Goneplacidae, although somites 3-5 are distinct but immovable in the family Mathildellidae of the superfamily Goneplacoidea. Another unique character for a goneplacid is the absence of the antennular septum. The vulva is also distinct, being surrounded by a sclerified, elevated prominence, a structure that has never been described in other goneplacids. In contrast to other goneplacines, the penis has a sclerified proximal portion that is externally visible (see Takeda &amp; Miyake 1969b: fig. 6 a, b). Although the male genital opening of the Euryplacidae has been described as sternal (Davie 2002), it is coxo-sternal, with the penis located in a groove or “canal” formed by the concave thoracic sternite 8. The flagellum of the G2 is long and with a distinctively curved, nearly coiled, tip, a character that is also observed in a goneplacine, Goneplacoides marivenae (Komatsu &amp; Takeda 2003: fig. 3e, as Goneplax marivenae, fig. 6e, as Goneplax megalops).</p> <p>All other morphological characters studied (thoracic sternum, female abdomen, relationship between abdomen and sternum in both sexes, and G1) are suggestive of strong goneplacine affinities. Neommatocarcinus is thus kept in the subfamily Goneplacinae rather than placing it in a new subfamily.</p> <p>Neommatocarcinus huttoni (Filhol, 1885) (Fig. 51)</p> <p>Ommatocarcinus huttoni Filhol, 1885a: 13, 50 [in list]; 1885b: 384, pl. 43, figs 1, 2, 5 [New Zealand]. — Dell 1951: 25 [in list] [New Zealand]. — Probert &amp; Batham 1979: 381, 387 [in list] [New Zealand]. — Wear &amp; Fielder 1985: 10 [in list], 62, 79 [in list], 84 [in key], figs 165-168 [larvae] [New Zealand]. — Guinot 1979: 219.</p> <p>Ommatocarcinus macgillivrayi – Miers 1886: xxiii, xxxvii, xlviii, 247 [New Zealand]. — Chilton 1911: 287 [in list], 292 [New Zealand]. — Thompson 1912: 237 [in list] [New Zealand]. — Thompson &amp; Anderton 1921: 99, unnumb. figs [larvae] [New Zealand]. — Chilton &amp; Bennett 1929: 757 [New Zealand]. — Richardson 1949: 36 [in key], fig. 21 [New Zealand]. — Dell 1960: 5; 1963a: 48, unnumb. fig.; 1968a: 26 [in list]; 1968b: 232, 233, 238 [New Zealand]. — Bennett 1964: 74, 88, figs 79-83 [New Zealand].</p> <p>Neommatocarcinus huttoni – Takeda &amp; Miyake 1969b: 174, 175, figs 5, 6, pl. 2, fig.

Chilton (1911: 292) considered them to be conspecific, and confusion persisted among most carcinologists until Takeda &amp; Miyake (1969b) pointed out the fusion of somites 3-5 in the male abdomen and other unique characters of O. huttoni and placed in a new genus, Neommatocaricinus.</p> <p>In addition to the male abdomen, N. huttoni can be distinguished from O. macgillivrayi by the absence of an antennular septum, the presence of 3 or 4 acute teeth (which become obtuse in large individuals; see Takeda &amp; Miyake 1969b: pl. 2, fig. A) on the proximal margin of the cheliped merus (one median, obtuse tooth in O. macgillivrayi), the absence of an obvious stridulating mechanism, a G1 with a slender tip (broader and dorso-ventrally flattened in O. macgillivrayi), a G2 with a curved flagellum (straight in O. macgillivrayi), and the absence of a ridge across the width of the carapace (Fig. 51) (present in O. macgillivrayi). In contrast to O. macgillivrayi, which was described by Takeda &amp; Miyake (1969b: 178) as “uniformly pinkish with darker spots”, the colour pattern of N. huttoni is rather striking (see Colour above).</p> <p>Neommatocarcinus huttoni, which is known by the common name of “policeman crab”, lives in sandy bottoms in temperate waters in New Zealand. It makes temporary furrows in the sand, leaving the long eye peduncles protruding from the sediment (McLay 1988: 264).</p> </div>	https://treatment.plazi.org/id/102B87CBFF0C25F2FC99FE7FFC67F97B	Public Domain	No known copyright restrictions apply.

Notch between front, inner edge of supraorbital border absent; orbits wide, deep, expanded distally (Clark &amp; Ng 2006: figs 2C, 4C, 5B); supraorbital borders with slightly raised median portion, smooth; suborbital borders with slightly raised median portion, inner tooth absent; lateral borders rounded, without tooth. Dorsal surface of carapace smooth, moderately convex, without clear indication of regions. Outer orbital angle without tooth. Basal antennal article short, distalmost (third) article does not reach front. Eye peduncles (Clark &amp; Ng 2006: figs 2A, C, 3A, 4A, C, 5A, B, 7) long, much shorter than front (0.3-0.4 front width); cornea small, spherical distal margin, not reniform (not conspicuously dorso-ventrally flattened, not clearly divided into anterior, posterior portions). No obvious stridulating mechanism other than possible rubbing of proximal portion of cheliped (P1) merus against pterygostomial ridge. Thoracic sternum wide. Median sulcus on thoracic sternite 4 absent; sutures 4/5, 5/6, 7/8 interrupted medially, 6/7 complete. Anterior end of sterno-abdominal cavity anterior to thoracic sternite 4. Cheliped fingers (Clark &amp; Ng 2006: fig. 6) short to relatively slender, slightly curved, shorter than propodus; dactylus without dark portion; inner (ventral) margin of propodus smooth; carpus with or without defined tooth on inner margin; merus short. Dorsal margins of ambulatory leg (P2-P5) meri (Clark &amp; Ng 2006: figs 2, 3E, 4, 5G, 7) unarmed; dactyli of ambulatory legs moderately slender, with carina on each side, with scattered setae. Male abdomen (Clark &amp; Ng 2006: figs 3F, 5H) with 6 freely-movable somites plus telson, relatively slender, somites 4-6 gradually decreasing in width from somite 3 (widest somite). Telson long, longer than wide. Somite 2 narrower than somite 3; somites 2, 3 leave large portion of thoracic sternite 8 visible. G1 (Serène &amp; Umali 1972: figs 92, 93; Serène &amp; Soh 1976: figs B, B’; Clark &amp; Ng 2006: figs 3H, I, 5J, K) relatively stout; elongated, bifurcated, or hooked tip; spinules on tip. G2 (Serène &amp; Umali 1972: figs 94, 95; Serène &amp; Soh 1976: figs C, C’; Clark &amp; Ng 2006: figs 3G, 5I) slender, longer than G1, flagellum longer than proximal part (peduncle); tip variously hooked, slightly enlarged tip without terminal spinule. Penis arising from P5 coxa, moderate size; broad, soft proximal expansion. Female abdomen with 6 freely-movable somites, relatively narrow, with relatively large distal portions of all thoracic sternites visible. Telson wider than long. Somite 2 slightly narrower than somite 3; somites 1, 2 leave large portion of thoracic sternite 8 visible. Vulva relatively large, round, extending from edge of suture 5/6 (displaced, slightly arched) to median portion of thoracic sternite 6, vulvar cover absent.</p> <p>REMARKS</p> <p>Notonyx has often, but not always, been included in the Goneplacidae (see review by Clark &amp; Ng 2006). Its carapace is uncharacteristically quadrate and lacks anterolateral teeth, hence its inclusion by Serène (1964) in the Chasmocarcinae Serène, 1964, as a subfamily of the Goneplacidae but now considered an independent family (see Table 1). In contrast to goneplacines, chasmocarcines have abdominal somites 3-5 fused in the male. The genus was nevertheless included in the family Notonycidae of the superfamily Notonycoidea by Števčić (2005). Clark &amp; Ng (2006) placed it in the Goneplacinae.</p> <p>The cornea of the eyes of Notonyx is much smaller than in goneplacines but the orbits are large (and unusually deep) and the eye peduncles long as in many goneplacines. There are similarities between the general structure of the G1 of Notonyx and those of goneplacines as well. The long G2, longer than the G1, is uncharacteristically curved at the tip, a character it nevertheless shares in part with Goneplacoides marivenae (Komatsu &amp;Takeda, 2003) (see Komatsu &amp; Takeda 2003: fig. 3e, as Goneplax marivenae, fig. 6e, as G. megalops). The slender male abdomen is similar to that of most geneplacines. Unlike goneplacines, however, somites 2 and 3 of both the male and female abdomens leave a large portion of thoracic sternite 8 visible. Notonyx appears to be a somewhat aberrant goneplacine, perhaps the result of morphological adaptations (most apparent in the shape of the carapace, the absence of anterolateral teeth, and the reduced corneas) to live in coarse sediments. At least N. gigacarcinicus Clark &amp; Ng, 2006 was collected from intertidal coral rubble.</p> <p>The genus needs to be revised, a task not undertaken during this investigation. The characters used by Clark &amp; Ng (2006) to differentiate the three known species are not clearly defined and it is clear that there are more species than those listed by them. It is possible therefore that a meticulous revision of the species may prove that Notonyx does not belong to the Goneplacinae but to an independent subfamily within the Goneplacidae.</p> </div>	https://treatment.plazi.org/id/102B87CBFF1325F0FF1EFF31FDFAFE6F	Public Domain	No known copyright restrictions apply.

Although the morphology of the brachyuran male gonopods, particularly the G1, and the male abdomen have been widely used by taxonomists for some time, practically no attention has been placed on the morphology of the female vulva as a taxonomic character. It is surprising, for instance, that few carcinologists have ever remarked on the conspicuously enlarged vulva of some goneplacids, particularly in Carcinoplax. An exception is Barnard (1950: 287), who included “Genital openings in adult ♀ very large” as one of the characters listed in his diagnosis of Carcinoplax.</p> <p>The morphology of the vulva and vagina among several groups of brachyurans was studied by Hartnoll (1968), who described two general arrangements (see also Guinot 1979): those having a vagina consisting of a simple tube with flexible walls and those with a vagina that is concave in cross section and localized muscles in the wall. A sclerified vulvar cover, mobile or immobile and referred to as an operculum, was found present among species belonging to the two groups. The vagina of Goneplax rhomboides, the only goneplacid studied by Hartnoll (1968: 296), was found to be intermediate between the two major groups, concave in outline but with flexible walls without localized muscles. The vulvar cover was absent.</p> <p>The morphology of the external reproductive structures goes beyond being another morphological character of practical use to taxonomists. There seems to be a correlation between the general morphology of the vulva and that of the G1 among goneplacines.</p> <p>It is speculated that this apparent correlation may be an adaptation to facilitate copulation (see discussion for other groups of brachyurans by Guinot 1979: 248). A large, greatly expanded vulva only protected by a soft membrane appears to be linked to a slender and thin (distinctly dorsoventrally compressed) G1. This is the case of eight goneplacine genera: Carcinoplax (see Fig. 1 for the vulva; Figs 2A; 4C; 6C; 9C for the G1), Entricoplax n. gen. (Fig. 11 for the vulva; Takeda &amp; Miyake 1968: fig. 5f, as Carcinoplax vestita, for the G1), Exopheticus n. gen. (Figs 49; 50 for the vulva; Fig. 48C for the G1), Goneplacoides n. gen. (Fig. 29 for the vulva; Komatsu &amp; Takeda 2003: fig. 3c, d, as Goneplax marivenae, for the G1), Goneplax sensu stricto (Capart 1951: figs 10-12, and Guinot 1969b: fig. 71a, b; 1989: fig. 46A, as Carcinoplax barnardi, for the G1), Hadroplax n. gen. (Serène &amp; Umali 1972: figs 78, 79, as Goneplax sinuatifrons, for the G1), Ommatocarcinus (Barnard 1950: fig. 53 f, and Dai &amp; Yang 1991: figs 199-1, 199-2, for the G1), and Paragoneplax n. gen. (G1 slender but bent in larger males, Chen 1998: fig. 12-6, as Goneplax serenei). The large size of the vulva in these genera, however, remains unexplained.</p> <p>In contrast, a small, not expanded vulva typically covered in part by a vulvar cover and linked with a stout, thick, sometimes bent, often spinous G1, is characteristic of six genera: Menoplax n. gen. (Fig. 12 for the vulva; Chen 1984: fig. 7-4 to 7-6 and Guinot 1989: fig. 32A, as Carcinoplax longispinosa, for the G1), Neogoneplax n. gen. (Fig. 32 for the vulva; Fig. 33 D and Chen 1998: fig. 11-4, as Goneplax renoculis, for the G1), Notonyx (Clark &amp; Ng 2006: figs 3H, I, 5J, K for the G1), Psopheticus (Fig. 47 for the vulva; Zarenkov 1972: fig. 6-5, Guinot &amp; Richer de Forges 1981b: fig. F, Guinot 1990: figs 44, 47, 50, 52, and Hsueh &amp; Huang 2002: figs 12D, H, for the G1), Pycnoplax n. gen. (Figs 14; 15; 18 for the vulva; Fig. 16C and Zarenkov 1972: fig. 6-2, Serène &amp; Lohavanijaya 1973: figs 158-162, Chen 1984: figs 4-5, 4-6, Guinot 1989: fig. 30A, as C. bispinosa; Guinot 1969b: fig. 73; 1989: fig. 31 A, Chen 1984: figs 3-5, 3-6, Dai &amp; Yang 1991: fig. 192-1, as C. surugensis, for the G1), and Thyraplax n. gen. (Figs 19, 22 for the vulva; Figs 20C; 23D; 25C for the G1).</p> <p>Some of the species of Microgoneplax n. gen. and Singhaplax present conditions that deviate from those described above. In Microgoneplax n. gen. the vulva is small, the vulvar cover is present, the G1 is thick as in the genera listed above (Figs 41C; 43B; 44B), but it is nevertheless thin and slender in one species, M. prion n. sp. (Fig. 45B). In Singhaplax the vulva is large, the vulvar cover is absent, but the G1 may be regarded as stout and thick in two of the species (Figs 35B; 38B; Serène &amp; Umali 1972: figs 86, 87, as Goneplax ockelmanni Serène &amp; Soh 1976: figs 15B, B’). In these two genera, however, females are known in only some of the species and the relative thickness of the G1 is difficult to ascertain due to the small size of the individuals. There are two other notable exceptions among the remaining goneplacine genera. In Neogoneplax costata n. sp. the vulva is small and provided with a vulvar cover (Fig. 32) but the G1 is clearly slender (Fig. 30C), in contrast to the other two species of Neogoneplax n. gen., where the G1 is predictably stout. In Neommatocarcinus huttoni, the G1 is slender (Takeda &amp; Miyake 1969b: fig. 5d) but the vulva, although covered by a soft membrane and lacking a vulvar cover, is bordered by a sclerified prominence.</p> <p>An alternative hypothesis is that the optimal size of the vulva is influenced more by its function as the opening through which eggs are released rather than as the location where the male pleopods deposit the sperm. Egg size, although not quantified among the goneplacines that were studied, does not seem to be noticeably or particularly larger in species with large vulvae than in those with small vulvae.</p> <p>The morphology of the vulvar cover varies widely among carcinoplacines and several patterns may be observed. However, it is never as complex as the hinged operculum of some brachyurans (see Thompson &amp; McLay 2005). The role and significance of the vulvar cover in the reproductive behavior of carcinoplacines remain unknown.</p> <p>The G2 is similar among practically all goneplacines, being slender and about the same size as the G1, which was considered a more primitive character by Guinot (1979: 243). Such a long G2 is known to be involved in the insemination of the vulva in some brachyurans (see Brandis et al. 1999; Guinot &amp; Quenette 2005). The notable exception, a G2 that is much shorter than the G1, is found in Menoplax n. gen. (Guinot 1989: fig. 32A, B, as C. longispinosa), Microgoneplax n. gen. (Figs 41C, D; 43B, C; 44B, C; 45B, C), and Paragoneplax n. gen. (Chen 1998: figs 12-6 to 12-9, as Goneplax serenei). There is no apparent correlation between the length of the G2 and the thickness, ornamentation, or general shape of the G1. In Carcinoplax (Figs 2A, B; 4C, D; 6C, D; 9C, D), Entricoplax n. gen. (Takeda &amp; Miyake 1968: fig. 5f, g, as Carcinoplax vestita), Exopheticus n. gen. (Fig.48C, D), Goneplacoides n. gen. (Komatsu &amp; Takeda 2003: fig. 3c, d, e, as Goneplax marivenae, fig. 6c-e, as G. megalops), Goneplax sensu stricto (Guinot 1969b: figs 71a, b, 72; 1989: fig. 46A, B, as Carcinoplax barnardi), Hadroplax n. gen. (Serène &amp; Umali 1972: figs 78-81, as Goneplax sinuatifrons), and Ommatocarcinus a long G2 is found together with a G1 that is thin, straight, and lacking conspicuous spines or teeth, a condition pointed out for Carcinoplax and several non-goneplacid genera by Guinot (1979: 241). The same basic type of long G2, however, is found in genera with thick, conspicuously spinous G1 as in Notonyx (Clark &amp; Ng 2006: figs 3G, 5I), Psopheticus (Guinot 1990: figs 44-54), Pycnoplax n. gen. (Fig. 16C, D), and Thyraplax n. gen. (Figs 20C, D; 23D, E; 25C, D). A long G2 is found together with a relatively slender G 1 in Neogoneplax serratipes n. sp. (Fig. 33D, E) and four species of Singhaplax (Figs 36B, C; 39B, C; 40A, B), but with a thick and spinous G 1 in N. costata n. sp. (Fig. 30C, D) and three species of Singhaplax (Figs 35B, C; 38B, C; Serène &amp; Umali 1972: figs 86-88).</p> <p>The goneplacine penis always arises directly from the male opening, which is found in the P5 coxa.It is uniformly soft but the proximal portion is sclerified in Neommatocarcinus. It was described as proximally sclerified in Ommatocarcinus by Guinot (1979: 219, fig. 54H) but this could not be verified.</p> <p>Sperm plugs were present on the vulvae of specimens of Pycnoplax bispinosa n. comb. (Fig. 15), P. victoriensis n. comb. (Fig. 18), and Psopheticus stridulans (Fig. 47). They have also been reported in Entricoplax vestita n. comb. (Doi &amp; Watanabe 2006). The role of sperm plugs in reproductive behaviour and sperm competition among goneplacines is unknown. Although sperm plugs are supposedly placed in the vagina by the first male to mate with soft-shelled females to prevent subsequent access to the spermatheca, in some species the plugs do not necessarily occlude the vulva nor prevent subsequent copulations (see Jensen et al. 1996).</p> <p>The morphology of the external reproductive structures of both sexes is unfortunately rarely available for study by paleontologists. The morphologies of these structures are not studied and are therefore missing from the descriptions and, most significantly, the suggested phylogenetic relationships that have been given by paleontologists. The importance of these structures for neontologists working with at least members of the family Goneplacidae is evidenced by the impossibility of reliably distinguishing between Microgoneplax n. gen. and Singhaplax, between Neommatocarcinus and Ommatocarcinus, and between Carcinoplax tenuidentata n. sp. and Pycnoplax bispinosa n. comb. without examining the external reproductive structures. The likely role of the structure of copulatory organs as an isolating mechanism among the sympatric species of Microgoneplax n. gen. and Singhaplax provides evidence of the obvious biological significance of these structures.</p> </div>	https://treatment.plazi.org/id/102B87CBFF1025F6FCB0FE3FFBBEF97B	Public Domain	No known copyright restrictions apply.
