In this family of hermaphrodites, the appendix masculina is presumably fused to the median portion of the Plp2 endopod which is densely setose or spinose mesially. The distal portion of the Plp2 endopod is large, and similar to that of the exopod, in Calocaris macandreae (Fig. 7D); it is less defined in Calastacus laevis (Fig. 5I).</p> <p>This work does not give as much importance as did Sakai &amp; de Saint Laurent (1989) to the thoracic sternite of P4 since its morphology does not vary much in the species studied, except for the presence of a spine on the lateral border (Fig.1I), and in its size. These are indicated in the diagnosis.</p> <p>A species probably not belonging to the European fauna but often mentioned in the past, Coralaxius nodulosus (Meinert, 1877) (better known as Axius nodulosus Meinert, 1877), is briefly treated.</p> </div>	https://treatment.plazi.org/id/03FF2C63FF98FF9A2ED97D92FCDE77DB	Public Domain	No known copyright restrictions apply.

Largest size reported: tl. 72 mm (Selbie 1914; Moyse &amp; Smaldon 1990).</p> <p>ECOLOGY AND BIOLOGY</p> <p>This species is known as difficult of capture as it retreats to its burrows when disturbed (d’Udekem d’Acoz 1995). It occurs intertidally from Fucus serratus zone to about 34 m depth where it burrows in coarse muddy sand with the entrance often hidden under a large rock (d’Udekem d’Acoz 1995, 1999). It is rare in the Atlantic, uncommon in the British Isles (Moyse &amp; Smaldon 1990), very rare in the Mediterranean. It is found in Plymouth under stone in mud where its larvae occur in the plankton in summer and early autumn (Gordon 1957). The species spawns at Roscoff, France, in July and August (Schlegel 1912). Larvae are rare in the plankton of Roscoff but are more frequent in Banyuls, France, in summer (Thiriot 1976), and common in July-September, off the French coasts of the English Channel (Martin 2001).</p> <p>The branchial morphology, gill area and gill ultrastructure were dealt with by Astall et al. (1997b); the diet by Pinn et al. (1998b); the gut morphology and gut microflora by Pinn et al. (1999a); mouth part setal fringes by Pinn et al. (1999b).</p> <p>REMARKS</p> <p>An amendation to stirhynchus of the original incorrect spelling stirynchus was proposed to the ICZN by Holthuis (1962) and validated under the plenary powers (ICZN 1964).</p> <p>The species has been quoted by several authors as having no suture on the uropod exopod. A suture actually exists, as revealed by Bouvier (1940) and Sakai &amp; de Saint Laurent (1989) but is often inconspicuous and placed near the posterior bor- der of the exopod.</p> <p>An illustration of this species from Nice in Risso’s manuscript notes, under the name Callianassa bisulcata, was discussed by Monod (1931) and Holthuis (1977). Both contended that Risso’s figure (fig. f) could hardly represent any other species in the area than Axius stirhynchus. The telson, correctly depicted with a convex posterior border and a pair of dorsal spines, confirms this view.</p> </div>	https://treatment.plazi.org/id/03FF2C63FF97FF912EDB7A97FF6675DB	Public Domain	No known copyright restrictions apply.

Specimens from the Mediterranean are smaller: cl. 5 mm and 7 mm, tl. 14.5 and 18.5 mm.</p> <p>ECOLOGY AND BIOLOGY</p> <p>The species lives in soft muddy bottom and deep waters, 162-578 m (present material), 440- 460 m in Denmark (Poulsen 1941) or 400- 424 m in Norway (Wollebaek 1909a).</p> <p>An extensive study in Norvegian waters by Brattegard (1966) reveals that this species is a mud eater, living in a depth range of 225- 670 m. It is found together with Calocaris macandreae; the latter dominates in shallow waters while C. coronatus does at depths of 500 m and below. C. coronatus has been collected in sediments of Md &lt;7.6 µm, at temperatures of about 6-7.5°C and salinity of 35‰. Ovigerous females are record- ed from March to November, all from depths exceeding 340 m. Egg-laying occurs during February-March; the eggs are carried for about 10 months and hatch in November-December.</p> <p>The larvae attributed to Calocarides coronatus and described by Elofsson (1959) were obtained from the Korstfjord (western Norway) over a muddy bottom, at 600 m depth. The development presumably includes at least three larval stages.</p> <p>REMARKS</p> <p>This deep water species is likely to be distributed from the north of Europe to the Mediterranean although it has not been reported from the British Isles or the European Atlantic coast so far. The specimens studied by Cartes et al. (1994) and García Raso (1996), though smaller, agree well with those from the north. Cartes (pers. comm.) also stated that C. coronatus was regularly found in Mediterranean waters, always at bathyal depths.</p> <p>In most of the material examined, Plp1 are absent in males as always previously reported. One exception nevertheless exists and small Plp1 are present in one specimen figured here (Fig. 3A).</p> <p>There is uncertainty about the synonymy of Axius (Neaxius) laevis Bouvier, 1915 with Calocarides coronatus as proposed by Sakai &amp; de Saint Laurent (1989: 82). The holotype and only known specimen of the former species is a young female in poor condition, of 20 mm in total length, with a broken rostrum and collected off the Moroccan coast (25°29’N, 18°18’W). It was partly figured (Sakai &amp; de Saint Laurent 1989: fig. 21) but unfortunately is now missing in the MNHN collection. Sakai &amp; de Saint Laurent (1989) stated that “Bouvier’s species laevis is to be included in coronatus because the dorsal region of the carapace and the abdomen are identical with those of coronatus ”. Yet the original description (Bouvier 1915: 182, 183) and Sakai &amp; de Saint Laurent’s figure (1989: fig. 21A-D) show several differences: 1) in A2 peduncle of Axius laevis, the upper distal spine of the second article reaches the middle of the antennal acicle (in C. coronatus, the same upper distal spine reaches one-third of the antennal acicle); 2) in A. laevis, the A2 acicle is two-thirds as long as the fourth article, the latter terminating approximately at the level of the A1 peduncle (Sakai &amp; de Saint Laurent 1989: fig. 21B) (in C. coronatus, the A2 acicle is about as long or slightly longer than the fourth article, the latter far overreaching the A1 peduncle, Figs 2S; 3C); 3) in the original description or figure by Sakai &amp; de Saint Laurent, there is no mention of submedian carinae and spines (these are present in C. coronatus, Fig. 3C); and 4) the telson is over 1.5 times as long as wide, with four or five spinules on the lateral border, the subdistal one largest in A. laevis (telson 1.3 times as long as wide in C. coronatus, with no spinule on the lateral border, Fig. 3B).</p> <p>Also doubtful is the assignement to Calocarides coronatus (“by geographical reason”, Sakai &amp; de Saint Laurent 1989: 79) of materials previously identified as Calocarides longispinis (McArdle, 1901) by Stebbing (1910: 367), Barnard (1950: 503, fig. 93d-f), Kensley (1981: 30), and two males in the MNHN collection. The three former materials were from South Africa while the MNHN specimens (MNHN Th 1044 and 1045) were collected off Namibia (26°26’S, 14°25’E and 20°1’S, 11°38’E respectively). The latter are very similar to specimens of C. coronatus but differ in: 1) their larger size, tl. 72.5 mm and 73 mm; 2) both P1 are laterally compressed, with upper and lower longitudinal rows of spines and spinules on merus, numerous tubercles on lateral surface; 3) larger P1 with fingers over two-thirds as long as the palm, dactylus nearly straight; and 4) large acute spines along the carinae of the telson and uropodal endopod.</p> </div>	https://treatment.plazi.org/id/03FF2C63FF93FF922EC57DE7FC4375FB	Public Domain	No known copyright restrictions apply.

Stephensen (1910: figs 1-4) depicted both P1, left P2, P4 of the type as well as the telson and uropods. Poulsen (1941: 209, fig. 2) reviewed and figured it in detail. Poulsen (1941: 213) believed that the specimen was a postlarva or a grown-up thalassinidean, but differed in one or more characters from all known postlarvae and young thalassinideans in the area. Likewise, no similarities are found between this specimen and the larvae referred to Calocarides coronatus (second stage, tl. 10 mm including rostrum), studied later by Elofsson (1959).</p> <p>Sakai &amp; de Saint Laurent (1989) assigned the species to the genus Coralaxius Kensley &amp; Gore, 1982. Meinert’s specimen resembles the type species of Coralaxius, C. abelei Kensley &amp; Gore, 1982 (from Florida and the Caribbean) in: 1) the short rostrum; 2) the morphology of both major and minor P1; 3) the morphology of P2; 4) the biunguiculate P4; and 5) the telson and uropods (see Stephensen 1910: figs 1-5 and Poulsen 1941: fig. 2 as compared with Kensley &amp; Gore 1982: figs 1-6 and Kensley 1994: figs 5, 6).</p> <p>Kensley (1994: 814), describing more materials of Coralaxius, considered further that Meinert’s specimen was “unquestionably a mature male of Coralaxius abelei ” (the species name nodulosus has therefore priority over abelei), that it “came from the Caribbean and the collection data became confused at some point”. Kensley’s argument seems convincing, and as C. nodulosus has not been collected again in the North Sea or European waters for over a century, it is likely to be an alien to the European fauna.</p> <p>Genus Levantocaris Galil &amp; Clark, 1993 TYPE SPECIES. — Levantocaris hornungae Galil &amp; Clark, 1993, by monotypy.</p> <p>DIAGNOSIS. — Rostral triangular, margin with denticles, short median carina present, lateral carina unarmed.

A colour- ed lithography is presented in Bouvier (1917: pl. 11, figs 5, 6).</p> <p>Size</p> <p>Specimens are larger in northern areas than in the south: the types from Loch Fyne, Scotland, are of about 2 inches (50 mm) (Bell 1846); ovigerous specimens from Norway of cl. 12.5- 15 mm, tl. 38.5-41.5 mm (SMF 28970).</p> <p>In Banyuls, France, largest specimens have cl. 10.5- 12 mm, tl. 31.5- 33 mm.</p> <p>ECOLOGY AND BIOLOGY</p> <p>The species is the most common thalassinidean in Norwegian waters, living in soft bottoms, between 15-580 m, and is most abundant below 50-100 m (Christiansen 2000). It occurs in soft bottoms, between 13-88 m, and is also collected at 310 m in Danish waters (Poulsen 1941). In muddy parts of the Clyde Sea area, it can be found everywhere and occasionally in stomach contents of cod, at 35-190 m (Allen 1967). It is a characteristic species of deep muddy bottoms in Marseille area (Pérès &amp; Picard 1964; Picard 1965).</p> <p>Aspects of biology studied</p> <p>General biology (Buchanan 1963); hermaphroditism (Wollebaek 1909b); burrow and burrowing behaviour (Nash et al. 1984); physiological ecology of burrowing (Atkinson &amp; Taylor 1988); anaerobic metabolism during anoxia (Anderson et al. 1994); branchial morphology, gill area and gill ultrastructure (Astall et al. 1997b); sulphide metabolism (Johns et al. 1997); particle size selectivity and resource partitioning (Pinn et al. 1998b); diet (Pinn et al. 1998a); gut morphology and gut microflora (Pinn et al. 1999a); mouth part setal fringes (Pinn et al. 1999b); effects of sulphide and thiosulphide on the respiratory properties of the haemocyanin (Taylor et al. 1999); oxygen transporting properties of the haemocyanin (Taylor et al. 2000); bioturbation (Widdicombe et al. 2000).</p> <p>REMARKS</p> <p>The genus Calocaris and the species Calocaris macandreae were first published in Bell’s book A History of the British Stalked-Eyed Crustacea (1844- 1853: 231-235). These pages were included in Part V of the book according to Gordon (1959) who also pointed out, on the authority of Dr H. O. Bull, that although “parts IV, V, VI were dated 1 st January (of 1846, 1847, 1848 respectively), they did in fact appear in the market by Christmas, 7 to 10 days earlier”.</p> <p>The genus Calocaris with the type species Calocaris macandreae were proposed to be placed on the Official list (Holthuis 1962) and validated under the ICZN plenary powers in 1964 (ICZN 1964).</p> <p>Calocaris macandreae has been reported from the Arabian Sea and the Bay of Bengal, off Sri Lanka (Alcock 1901), and also from the Gulf of St Lawrence, Canada (Whiteaves 1901).</p> <p>Comparison of Alcock’s description with the present material of Calocaris macandreae confirms Selbie’s view (1914) that the Indian specimens belong to a closely related but separate species. The same must be said of those reported by Alcock &amp; Anderson (1894: 163) from the Indian fauna. The specimen taken by Whiteaves was assigned to a new species, Calocaris templemani Squires, 1965 reported from Hermitage Bay, Newfoundland (Squires 1965) and probably also those from the Atlantic Canada, described by Rathbun (1929: 25, fig. 33).</p> <p>Male and female gonopores appear together on young adults of Calocaris macandreae confirming Buchanan (1963) view that the species is not a protandric hermaphrodite.</p> </div>	https://treatment.plazi.org/id/03FF2C63FF8BFF872D657872FE0E727B	Public Domain	No known copyright restrictions apply.

(2000), the latter with a cladistic analysis. Various classification systems have been proposed sometimes with large differences. Reexamination of materials has been necessary and choices have been made concerning the taxonomy of European Callianassidae and Ctenochelidae.</p> <p>This work uses the familial and subfamilial divisions proposed by Tudge et al. (2000) and adopts the alternative suggested by these authors which is to provisionally leave the genus Callianassa as a polyphyletic group. The diagnosis of Callianassa s.l. is given below.</p> <p>The species Callianassa acanthura Caroli, 1946, Callianassa truncata Giard &amp; Bonnier, 1890 and Necallianassa berylae Heard &amp; Manning, 1998 were placed by Heard &amp; Manning (1998) in the new genus Necallianassa on the ground of lateral spines on the telson and the uropodal endopod. These spines are however much smaller in C. truncata (Fig. 11D) than in the other two species (Fig. 8G). Furthermore, Necallianassa berylae has a large rostral spine which is absent in the other two species, and in both C. truncata (Fig. 11I) and N. berylae, female Plp2 bears a distal appendix interna on the endopod and lacks it in C. acanthura (Fig. 8O). The latter character is regarded as of generic importance.</p> <p>In summary, Necallianassa berylae, the type species, possesses a large rostral spine, large acute lateral spines on the telson and uropods and an appendix interna on female Plp2.</p> <p>C. acanthura differs by having no rostral spine, no appendix interna on female Plp2.</p> <p>C. truncata differs by having no rostral spine, no large acute spines on the telson and uropods.</p> <p>Although Sakai (1999a: 128) synonymised Necallianassa with Callianassa, this genus can be diagnosed using the characters mentioned above for the type species. But the inclusion of C. acanthura and C. truncata does not seem justified. Both species are reassigned to the genus Callianassa s.l.</p> <p>The species Callianassa candida (Olivi, 1792), C. tyrrhena (Petagna, 1792) and C. whitei Sakai, 1999 and two others from the eastern Atlantic are separated into a new genus, Pestarella n. gen.</p></div> 	https://treatment.plazi.org/id/03FF2C63FF85FF872EED7A92FB6275BA	Public Domain	No known copyright restrictions apply.

Eyestalk short, flattened dorsoventrally; cornea subdistal, dorsal or dorsolateral. Mxp1 with anteriorly truncate epipod, endopod minute. Mxp2 with small epipod. Mxp3 lacking exopod, subpediform or operculiform; propodus not expanded ventrally, less than three times as wide as dactylus, latter digitiform, at least twice as long as wide.</p> <p>P1 unequal, usually with meral hook, P2 chelate, P3 and P4 simple, P5 subchelate.

Plp3-5 with stubby, projecting appendix interna. Uropodal exopod with dorsal plate.</p> <p>REMARKS</p> <p>The genus Callianassa is provisionally considered a polyphyletic group, with the species included as listed in Tudge et al. (2000). Sakai (1999a) proposed a much broader concept of the genus as he synonymised several genera erected by Manning &amp; Felder (1991) with Callianassa. Although his action is not considered fully justified, the genera established by Manning &amp; Felder (1991), focusing on American callianassids, probably need to be reconsidered, especially in view of their global use. Examination of the abundant, highly diverse material from the Indo-Pacific, together with a detailed phylogenetic analysis is desirable to show the true relationships between species and provide a solid base for their grouping. This however is beyond the scope of this work.</p> <p>Nevertheless a number of additional characters, besides those given by Tudge et al. (2000), are suggested to be useful in the taxonomic study of this genus. Taking the three European Callianassa species as an example, it can be noted that, though they all fit the diagnosis of the genus as given above, C. subterranea has a slender minor P1 (Fig. 9C) not compressed laterally, with the carpus four or five times as long as wide; the P3 (Fig. 9J) propodus not ovate, with the lower border dentate; the third segment of Md palp (Fig. 9M) of same width throughout and the basal endite of Mx1 (Fig. 10A) approximately rounded distally.</p> <p>By contrast, C. acanthura and C. truncata have the minor P1 (Fig. 8D) slightly compressed laterally, with the carpus less than twice as long as wide; the P3 propodus ovate (Fig. 8F) with the lower border regularly curved; the third segment of Md palp (Fig. 8K) narrowing distally and the basal endite of Mx1 (Fig. 8E) of inverted-triangle shape with an expanded distal border bearing spiniform setae.</p> <p>These characters were not considered by Tudge et al. (2000) in their analysis but are probably of phylogenetic significance; those of C. acanthura and C. truncata are presumably apomorphic.</p> <p>Callianassa acanthura Caroli, 1946 (Fig. 8)</p> <p>Callianassa acanthura Caroli, 1946: 66, figs 1a, 2. — Holthuis 1953: 94, fig. 5. — Monchartmont 1979: 71. — de Saint Laurent &amp; Božić 1976: 21, figs 3, 11, 19, 25, 30. — Türkay 1982: 225; ° 2001: 289. — ° Türkay et al. 1987: 92. — ° Koukouras et al. 1992: 223. — Noël 1992: 81. — ° Froglia 1995: 7. — Falciai &amp; Minervini 1996: 147, 3 figs. — d’Udekem d’Acoz 1996: 54, 56. — Abed-Navandi &amp; Dworschak 1998: 605, figs 1-8. — Sakai 1999a: 14, 128 (addendum). — ° Türkay 2001: 289.</p> <p>Callianassa (Trypaea) acanthura – Zariquiey Alvarez 1968: 229.</p> <p>Necallianassa acanthura – Heard &amp; Manning 1998: 883. — d’Udekem d’Acoz 1999: 155.</p> <p>TYPE MATERIAL. — Lectotype:, Naples, Italy, E.

It is abundant on sublittoral sandy bottoms of the Kornati Archipelago and near Rovinj, in fine or medium sand, at 3-6 m depth, associated with the fish Trachinus sp. and Bothus sp. (Abed-Navandi &amp; Dworschak 1998).</p> <p>REMARKS</p> <p>This species, together with Necallianassa berylae Heard &amp; Manning, 1998, can be distinguished from all other callianassids by the presence of large acute spines on the lateroposterior border of the telson and uropodal endopod, as well as proximally on the uropodal exopod. Spines are present on the lateroposterior border of the telson in a few other species, e.g., C. truncata or C. intermedia de Man, 1905 (see Sakai 1999a: 128) but in none of these are they so large (about onefifth length of telson and uropodal endopod in C. acanthura) and acute.</p> <p>Among its European and Mediterranean congeners, C. acanthura is close to C. truncata but differs essentially in: 1) the large acute spines on the telson and uropods, as mentioned above; and 2) the absence of an appendix interna on female Plp2.</p> <p>Callianassa subterranea (Montagu, 1808) (Figs 9; 10)</p> <p>Cancer Astacus subterraneus Montagu, 1808: 89, pl. 3</p> <p>figs 1, 2.

According to de Saint Laurent &amp; Božić (1976), the species is common in the northern part of its distribution range (Great Britain, Denmark, Norway), scarce along the atlantic coast of France and in the Mediterranean with smaller specimens living in deeper waters (35-500 m).</p> <p>DIAGNOSIS</p> <p>Carapace (Fig. 9A) with dorsal oval; rostrum approximately triangular with blunt tip, rostral spine absent. Telson (Fig. 9F) about as long as proximal width, narrowing distally, lateral border convex proximally, posterior border with median spinule. Eyestalk (Fig. 9A) short, cornea dorsal, indistinct. A1 peduncle shorter than that of A2. Md (Fig. 9M) with three-segmented palp, last segment of same width throughout. Mx1 and Mx2 (Fig. 10A, B) as figured. Mxp1 (Fig. 10C) with small rounded endopod, epipod without anterior lobe. Mxp2 (Fig. 10D) with short exopod. Mxp3 (Fig. 9D, E) subpediform; row of 13-15 spines on mesial surface of ischium, smaller proximally; propodus about 1.5 as long as wide; dactylus 2.5- 3 times as long as wide.</p> <p>Major P1 (Fig. 9B) stouter in male than in female, strong meral hook, curved anteriorly, smooth or with denticles on proximal border; carpus about as long as distal width, propodus slightly longer, cutting edge of fixed finger and dactylus unarmed or with small round teeth. Minor P1 (Fig. 9C) slender with carpus approximately four times as long as distal width. P2 (Fig. 9I) as figured. P3 (Fig. 9J) propodus with lower border dentate bearing separated tufts of setae, no proximal heel. P4 (Fig. 9K) propodus slender, nearly three times as long as wide. P5 (Fig. 9L) subchelate.</p> <p>Male Plp1 (Fig. 9G) uniramous, male Plp2 (Fig. 9H) small, sometimes absent. Female Plp1 (Fig. 9O) uniramous, female Plp2 (Fig. 9P) biramous, exopod overreaching endopod.</p> <p>Plp3-5 (Fig. 9N) biramous, foliaceous, appendix interna approximately cylindrical, partly embedd- ed, distal half projecting from inner border of endopod. Uropodal endopod (Fig. 9F) about as long as telson; exopod longer, setal row of dorsal plate at short distance from posterior border.</p> <p>Colour</p> <p>Colour during life more or less orange, sometimes yellow on the sides and on the tail, the arms usually pink (White 1857); dorsal abdomen pale pink (Dworschak pers. comm.); white to light pink or light blue (Campbell &amp; Nicholls 1986).</p> <p>Size lectotype of cl. 13 mm, tl. 52 mm; paralectotype of cl. 12 mm, tl. 47.5 mm.</p> <p>In the present material examined, specimens are larger in northern Atlantic, of cl. 10-13 mm, tl. 42-52 mm, smaller in southern Atlantic (e.g., France, Spain) and in the Mediterranean, of cl. 4-8 mm, ovigerous of cl. 4.5-5.5 mm.</p> <p>ECOLOGY AND BIOLOGY</p> <p>This species shows all the characteristics of a deposit feeder, according to Stamhuis et al. (1997). It is common in subtidal (10-80 m) muddy fine sands and muds (Adema et al. 1982; Dworschak 1992; Moyse &amp; Smaldon 1990). In Plymouth, UK, larvae are very common in the plankton in summer and early autumn (Gordon 1957).</p> <p>Its ecology and general biology including burrow structure in the North Sea were dealt with by Witbaard &amp; Duinevelt (1989), Atkinson &amp; Nash (1990), Rowden &amp; Jones (1994, 1995).</p> <p>Other aspects of biology studied</p> <p>Burrow morphology and feeding behaviour (Nickell &amp; Atkinson 1995); burrows and bioturbation (Rowden &amp; Jones 1997); burrow architecture and burrow ventilation (Stamhuis et al. 1997; Stamhuis &amp; Videler 1998); branchial morphology, gill area and gill ultrastructure (Astall et al. 1997b); sulphide metabolism (Johns et al. 1997); morphology of mouthparts and pereopods in relation to feeding, ecology and grooming (Nickell et al. 1998); morphology, motion and function of appendages (Stamhuis et al. 1998a); size selectivity and resource partitioning (Pinn et al. 1998b); optimal foraging and grain size selection (Stamhuis et al. 1998b); role in sediment turnover resuspension (Rowden et al. 1998); gut morphology and gut microflora (Pinn et al. 1999a); effects of burrows on sedimentswater solute fluxes (Hughes et al. 2000); oxygen transporting properties of haemocyanin (Taylor et al. 2000).</p> <p>REMARKS</p> <p>As reported by de Saint Laurent &amp; Božić (1976), the specimen from Helgoland assigned by Lutze (1938) to Callianassa pestae (p. 167, figs 10-21) as well as his new species Callianassa helgolandica (p. 174, figs 52-61) actually belong to C. subterranea. This is confirmed by the figures of their Mxp3, both subpediform (fig. 11, also part of fig. 26a, b for C. pestae and fig. 53 for C. helgolandica). On the other hand, Dworschak (1992: 205) contends that the specimen collected by the “Pola Expedition” (NHMW 6613) and mention- ed by Adensamer (1898: 620) is in fact a juvenile of the present species, not of Gourretia denticulata (Lutze 1937).</p> <p>There is variation in the length of major P1 carpus and propodus, also in the length and shape of the dactylus and fixed finger. This appears to be not linked with sex (Nickell et al. 1998).</p> <p>Callianassa truncata Giard &amp; Bonnier, 1890 (Fig. 11)</p> <p>Callianassa truncata Giard &amp; Bonnier, 1890: 362, figs 2, 4. — Caroli 1940: 73; 1946: 66, figs 1b, 3. — Holthuis 1953: 91, fig. 4. — * Bourdillon-Casanova 1960: 108. — Picard 1965: 38. — Lagardère 1966: 195, pls 2-5; 1973: 84. — ° Faure 1970: 773. — de Saint Laurent &amp; Božić 1976: 19, figs 2, 10, 18, 29. — Beaubrun 1979: 84, figs 56, 57, 62-64. — Monchartmont 1979: 72. — ° Kocataș 1981: 162. — Mikashavidze 1981: 1417. — Thessalou-Legaki &amp; Zenetos 1985: 309. — Thessalou-Legaki 1986: 183. — ° Koukouras et al. 1992: 223. — Noël 1992: 81. — ° Froglia 1995: 7. — Falciai &amp; Minervini 1996: 147, 4 figs. — d’Udekem d’Acoz 1996: 54. — Ziebis et al. 1996: 619, fig. 1. — Abed-Navandi &amp; Dworschak 1997: 565, figs 1-8. — Sakai 1999a: 20. — *González-Gordillo et al. 2001: 279. — Markham 2001: 197. — ° Türkay 2001: 289.</p> <p>Callianassa italica Parisi, 1915: 64, figs 1, 2.</p> <p>Callianassa (Trypaea) italica – de Man 1928a: 11, figs 5- 5h; 1928b: 27, 101.</p> <p>Callianassa (Trypaea) truncata – Borradaile 1903: 546. — de Man 1928 b: 28, 101. — Bouvier 1940: 102, fig. 68. — Gurney 1944: 82, figs 1E, 3, 4. — Zariquiey Alvarez 1950: 81, fig. 1, pl. 6 figs 1-6, pl. 7 fig. 2; 1968: 229. — *Dolgopolskaia 1954: 186, figs 5-9; *1969: 316, pls 35-38.</p> <p>Callianassa (Trypaeta) truncata. —* Băcescu 1967: 229, fig. 104.</p> <p>Necallianassa truncata – Heard &amp; Manning 1998: 883. — d’Udekem d’Acoz 1999: 156. — Dworschak et al. 2000: 302. — * Lindley et al. 2001: 46. — Markham 2001: tabls 1, 2.</p> <p>Pestaina truncata – Öksnebjerg 2000: 78 nomen nudum.</p> <p>TYPE MATERIAL. — Whereabouts unknown.</p> <p>MATERIAL EXAMINED. — France.

Telson (Fig. 11D) about as long as proximal width, a little narrower distally; lateral borders weakly convex, lateroposterior corner with two transparent minute spines, posterior border with median spinule.</p> <p>Eyestalk short (Fig. 11A), cornea dorsal, subterminal, disk-shaped. A1 peduncle approximately as long as that of A2. Md (Fig. 11F) with three-segmented palp, last segment tapering distally. Mx1 (Fig. 11G) with basal endite of inverted triangle, distal border widened bearing spiniform setae. Mxp3 (Fig. 11J, K) operculiform, length about 1.6-1.7 times merus width, ischium with row of 15-16 spinules on mesial surface; propodus about 1.6-1.7 times as long as wide; dactylus 1.8-2 times as long as wide.</p> <p>P1 unequal in adult male and female, subequal in certain small specimens. Major P1 of male (Fig. 11C) with lower border of merus convex on distal half bearing small rounded teeth; meral hook pointed distally, denticulate on both proximal and distal border; carpus unarmed; propodus dentate on lower border; dactylus with curved tip and dense setae on proximal two-thirds and near base of fixed finger. Major P1 of smaller male and of female similar to that of male but more slen- der, with fewer or very few setae (in female) on dactylus. Minor P1 (Fig. 11B) slightly compressed laterally, merus with median spine on lower border, carpus about 1.4-1.5 times as long as wide and 1.5 as long as propodus, lower border regularly curved. P3 (Fig. 11E) propodus approximately oval, with lower border rounded, no proximal heel. P4 propodus slender, over three times as long as wide.</p> <p>Male Plp1 (Fig. 11L) small, male Plp2 absent. Female Plp1 (Fig. 11H) uniramous, female Plp2 (Fig. 11I) biramous, exopod about as long or slightly longer than endopod, latter with distal appendix interna. Pleopods 3-5 (Fig. 11M) foliaceous, appendix interna approximately cylindrical, slightly narrowing distally, partly embedded, partly projecting from inner border of endopod.</p> <p>Uropod (Fig. 11D) as long as telson; exopod with distal setal row of dorsal plate at short distance from posterior border; endopod with small lateral distal spine.</p> <p>Colour</p> <p>Body yellowish, abdomen dull yellow, pereopods whitish (d’Udekem d’Acoz 1996).</p> <p>Creamy to yellowish on dorsal abdomen, chelipeds white, sometimes yellow, hepatopancreas orange-brown, ripe ovaries bright orange-red (Dworschak pers. comm.).

It seems to prefer fine sand and can be locally abundant (d’Udekem d’Acoz 1996). According to Picard (1965), C. truncata is characteristic of muddy bottoms along the coast of France. In the Bay of Biscay and nearby areas, specimens were captured in the littoral and at 44-57 m depth (Lagardère 1965).</p> <p>REMARKS</p> <p>De Saint Laurent &amp; Božić (1976) cited a pair of fine spinules on each lateroposterior angle of the telson and a small laterodistal spine on the uropodal endopod as diagnostic characters for this species. It must be noted, however, that the spinules on the lateroposterior angle of the telson (figured in this work) are transparent and indistinct in most specimens. By contrast, the laterodistal spinule on the uropodal endopod is obvious. It makes a good distinguishing feature for the species in Europe, together with the lower meral spinule on the minor P1.</p> <p>In certain populations of small size, e.g., MNHN Th 1415 from Pogonia, Greece, all females (eight specimens with seven ovigerous, cl. 4-5.5 mm) have their P1 subequal and similar to the minor P1 of males. This does not occur in larger specimens, e.g., those of cl. 8-9 mm.</p></div> 	https://treatment.plazi.org/id/03FF2C63FF85FFB92D0B7C72FB97725A	Public Domain	No known copyright restrictions apply.

The present generic name fulfills that intention. The genus nevertheless has not hitherto been erected and the names Pestaina truncata and Pestaina candida used by Öksnebjerg (2000: 78) are nomina nuda.</p> <p>In the subfamily Callianassinae of the Callianassidae, the new taxon is related to Callianassa. It differs by the telson rounded in posterior half, the operculiform Mxp3, and the absence of Plp1 and Plp 2 in males.</p> <p>Apart from Pestarella whitei n. comb., the four other species of this genus were placed in a small group within Callianassa by de Saint Laurent &amp; Le Loeuff (1979: 96). They inhabit eastern Atlantic: three European species, P. convexa n. comb. from Senegal and P. rotundicaudata n. comb. from South Africa.</p> <p>Pestarella candida (Olivi, 1792) n. comb.

It is also common in coarse sand or mud in the intertidal and shallow subtidal, at 7-9 m depth (García Raso 1983; Thessalou-Legaki &amp; Zenetos 1985). Its burrow and functional morphology are reported in Dworschak (2002).</p> <p>REMARKS</p> <p>This species has been known in the past under Callianassa pontica or Callianassa pestae (pestai) and the priority of these names was discussed by Holthuis (1953) and de Saint Laurent &amp; Božić (1976). In 1986, Lewinsohn &amp; Holthuis pointed out the priority of the name candida. Although both Dworschak (1992) and d’Udekem d’Acoz (1999) found Lewinsohn and Holthuis’ arguments (based on the white chelipeds of the species) not quite convincing, especially given the rudimentary work by Olivi (1792), the name candida was used by both, and also in this work, for the sake of nomenclature stability. Sakai (1999a) selected a neotype (SMF 23572) for the species.</p> <p>As reported by de Saint Laurent &amp; Božić (1979: 26), a part of the material assigned by Lutze (1938) to Callianassa algerica and now deposited in MNHN (MNHN Th 96-98), belongs to the present species. The identity of the two forms is confirmed.</p> <p>Variations occur in: 1) the eyestalk distal tip is blunt or mesiodistally produced; 2) the lower border of P1 merus is straight or convex; 3) the length ratios of carpus/propodus/fingers vary in both P1; and 4) the meral hook of the major cheliped is often relatively large with the lower bor- der straight and a distinct pointed distal tip (Fig. 12B) or smaller with the lower border convex and the distal tip more discrete (Fig. 12D).</p> <p>Besides characters given in the key, additional details differentiating P. candida n. comb. and its two congeners are presented under these latter species.</p> <p>Pestarella tyrrhena (Petagna, 1792) n. comb.

Picard &amp; Pérès (1964) and Picard (1965) considered this species as characteristic of a relatively undisturbed muddy subtrate.</p> <p>Aspects of biology studied</p> <p>Feeding behaviour (Dworschak 1987a); cadmium, mercury bioaccumulation and their effects (Thaker &amp; Haritos 1989a, b); reproductive output (percentage of mother weight devoted to egg production) (Thessalou-Legaki &amp; Kiortsis 1997); physiological aspects in relation to pollution (Thessalou-Legaki et al. 1997); biometric analysis (Dworschak 1998a); abundance of population in Corsica (de Vaugelas 1991); relation between burrow architecture, feeding mode and structure of the sediments (de Vaugelas 1998); burrow and burrow construction with role of tegumental glands (Dworschak 1998 b, 2000).</p> <p>REMARKS AND VARIATIONS</p> <p>This is the most common callianassid species along the French Atlantic coast and the European coast of the Mediterranean, with much confusion in nomenclature.</p> <p>It was described by Otto (1821, 1828) under the name Callianassa laticauda but was often confused with C. subterranea (Montagu, 1808). In 1893, Stebbing reported some Callianassa material from Jersey which he considered distinct from subterranea and which was named later Callianassa Stebbingi by Borradaile (1903). De Man (1928a) showed its identity with C. laticauda.</p> <p>Giordani Soika (1943) stated that Cancer candidus Olivi, 1792 was identical with Callianassa laticauda Otto, 1821, and that Olivi’s name, being the older of the two, should be employed. On the other hand, Holthuis (1947) considered that the three names Astacus tyrrhenus Petagna, 1792, Cancer candidus and Callianassa laticauda actually referred to the same species. He (Holthuis 1953) definitely settled the question and presented the main reason why Petagna’s name should be preferred over Olivi’s (Petagna’s figure is far superior). The species name tyrrhena (Petagna, 1792) has been used therafter.</p> <p>Variations occur in: 1) the lower border of major P1 merus which is straight or slightly convex; 2) the length ratio of carpus/propodus/fingers in major P1, with fingers often shorter in male than in female; and 3) the Mxp3 ischium (Fig. 13G) is often, not always, narrower proximally than distally and narrower than the merus. The colour pattern is also variable: whilst most specimens are more or less tinged with pink, specimens with completely white pereopods are occasionally found (d’Udekem d’Acoz pers. comm.).</p> <p>Characters given for this species in the key are reliable but its European congeners can also be differentiated by the dorsal plate of the uropodal exopod: its setal distal row is at short distance and indistinct from the posterior border in P. tyrrhena n. comb. and well apart from the posterior border in P. candida n. comb. and P. whitei n. comb.</p> <p>Pestarella whitei (Sakai, 1999) n. comb.

Telson (Fig. 15D) with proximal width about 1.5 times median length.</p> <p>Eyestalk short, distal tip blunt or slightly pointed mesially; cornea disk-shaped, dorso-lateral or dorsal. Peduncle of A1 longer and stouter than that of A2. Mxp3 (Fig. 13F) operculiform, ischium-merus length about 1.5-1.6 times merus width, propodus slender, about twice as long as wide, lower border nearly straight, dactylus digitiform, 2.5-3 times as long as wide.</p> <p>Major P1 (Fig. 15B) merus with lower border straight or slightly convex, lower border of meral hook denticulated, pointed distally.

(Dworschak pers. comm.).</p> <p>Size</p> <p>Holotype: cl. 11-12 mm, tl. 49 mm.</p> <p>ECOLOGY</p> <p>Living in mud, under stones or in seagrass meadows, 0-4 m (Sakai 1999a; Dworschak 2002).</p> <p>REMARKS</p> <p>The chelipeds of the holotype (Sakai 1999a: fig. 4c, d) were probably figured in situ and certain features are inaccurate, e.g., the shape of the major P1 meral hook, or the length ratio of the carpus and propodus. The figures are also presented as mirror images, as if the major cheliped was on the left and the minor cheliped was on the right while it is actually the opposite. The two appendages are here detached from the body and laid flat for drawing (Fig. 15B, C). Their morphology is very similar to that of P. candida n. comb.</p> <p>In his work on the fauna of the Adriatic, Pesta (1918: fig. 63, 63a, 63b) reported some material he assigned to Callianassa stebbingi (= P. tyrrhena n. comb.). Later, de Man (1928a: 34) and de Saint Laurent &amp; Božić (1976: 24) placed it in C. pestae or C. pontica (= P. candida n. comb.), while Sakai (1999a: 23) considered it to belong to P. whitei n. comb.</p> <p>The material examined by Pesta was probably a mixture of P. candida n. comb. and P. tyrrhena n. comb. (and also P. whitei n. comb.). Figure 63 of Pesta (1918) is likely to represent a specimen of the former species (meral hook of major P1 with pointed distal tip, uropodal exopod with setal row of dorsal plate well apart from posterior bor- der). Figure 63a (an operculiform Mxp3) could be of either species, while figure 63b is clearly of P. tyrrhena n. comb. (telson about as long as wide, uropodal exopod with setal row of dorsal plate near posterior border). This material (or part of it) is still extant and housed at the Natur- historisches Museum Vienna. It includes specimens of P. candida n. comb. (Dworschak pers. comm. and sketch) with an exception (NHMW 319) that could be a variation of P. whitei n. comb. (peduncle of A1 slightly longer than that of A 2 in one side, about as long in the other; Mxp3 propodus slender).</p> <p>Pestarella whitei n. comb. is similar to P. candida n. comb. in: 1) the eyestalk is short with the distal tip blunt or slightly pointed mesially; 2) the morphology of both P1; 3) the telson is wider than long; and 4) the uropodal exopod and endopod greatly exceed the telson. Distinguishing features are listed in the key and this species can be differentiated from its European congeners especially by the shape of its Mxp3 propodus (Fig. 15E, F). The latter is slender, approximately twice as long as wide, with the lower border nearly straight, while it is 1.5 times as long as wide, with the lower border convex in P. candida n. comb. and P. tyrrhena n. comb.</p> <p>Pestarella whitei n. comb. is also similar to a non- European congener, but with a close distribution range, which is P. convexa n. comb. from Senegal (de Saint Laurent &amp; Le Loeuff 1979: 73, fig. 10). It differs in: 1) the telson is about 1.5 times as wide as long in P. whitei n. comb. (1.3-1.4 times in P convexa n. comb.); 2) uropods are more elongated, endopods nearly twice as long as telson in P. whitei n. comb. (uropodal endopod about 1.5 times as long as telson in P. convexa n. comb.); and 3) the uropodal exopod with the setal row of dorsal plate well apart from posterior border in P. whitei n. comb. (setal row of dorsal plate near posterior border in P. convexa n. comb.).</p> </div>	https://treatment.plazi.org/id/03FF2C63FFBBFFB22D727A67FBCB745B	Public Domain	No known copyright restrictions apply.

The holotype and only known specimen was a damaged specimen, with the abdomen and pereopods 4 and 5 missing. The species was redescribed and partly figured by Sakai (1999a: 8, fig. 1) who erected a new subfamily, Calliapaguropinae, for it. Recently, a new species, Calliapagurops foresti Ngoc-Ho, 2002, was described from the Philippines. The type material includes four specimens, three of them complete and in good condition. Their examination complements the diagnosis of the genus as given above. It also reveals that Calliapagurops is better placed in the subfamily Callichirinae sensu Tudge et al. (2000). The latter, which was synonymised with the Callianassinae by Sakai (1999a), is regarded as a valid subfamily (Ngoc-Ho 2002).</p> <p>Calliapagurops charcoti de Saint Laurent, 1973 (Fig. 16)</p> <p>Calliapagurops charcoti de Saint Laurent, 1973: 515. — Manning &amp; Felder 1991: 771. — Sakai 1999a: 8, fig. 1. — Tudge et al. 2000: 141. —?* Lindley et al. 2001: 46. — ° Türkay 2001: 289. — Ngoc-Ho 2002: 540.</p> <p>TYPE MATERIAL. — Holotype: from Azores, Jean Charcot, BIAÇORES, stn 109, 39°33’N, 31°17’W, 190-230 m, in shelly sand, 20.X.1971, cl. 9.5 mm without abdomen and P4, P5 (figured, MNHN <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=-31.283333&amp;materialsCitation.latitude=39.55" title="Search Plazi for locations around (long -31.283333/lat 39.55)">Th</a> 345).</p> <p>DISTRIBUTION. — Only known from the type locality, at 190- 230 m.</p> <p>DIAGNOSIS</p> <p>As for the genus, with details added: eyestalk reaching base of last article of A1 and not narrowing distally (Fig. 16A).

A number of Calliax and Eucalliax species have been described recently. Their examination confirms the validity of the latter genus and permits the former to be better defined.</p> <p>Both Calliax and Eucalliax comprise species of Eucalliacinae having no exopod on the Mxp3. It is proposed that two of these are assigned to Calliax: Calliax lobata (de Gaillande &amp; Lagardère, 1966) (type species) and Calliax doerjesti Sakai, 1999.</p> <p>A short diagnosis for the American species of Eucalliax was given by Manning &amp; Felder (1991: 781). It is here amended after examination of new materials.</p> <p>Rostrum triangular, rostral spine small or absent; cornea flatttened, almost terminal. A1 peduncle shorter than that of A2. Mxp3 without exopod, operculiform. Chelipeds equal and similar, major without meral hook. Male and female Plp1 slender and uniramous, lacking appendix interna; male and female Plp2 slender and biramous, male Plp2 with appendix interna and appendix masculina, female Plp2 often with appendix interna (absent in E. quadracuta). Plp3- 5 foliaceous and biramous in both sexes, with finger-like appendix interna. Telson over 1.5 times as wide as long, posterior border straight or slightly concave, often with dorsal transverse carina (absent in E. bulimba). Uropods longer than telson, endopod overreaching telson by at least half its length.</p> <p>It can be noted that the Mxp3 figured by Manning &amp; Felder (1991: fig. 3) and labeled as Eucalliax actually belongs to Calliax lobata as indicated in the legend.</p> <p>The following species are placed in Eucalliax: Eucalliax quadracuta (Biffar, 1970) (type species), Eucalliax aequimana (Baker, 1907) n. comb., Eucalliax bulimba (Poore &amp; Griffin, 1979) n. comb., Eucalliax cearaensis Rodriguez &amp; Manning, 1992, Eucalliax jonesi (Heard, 1989), Eucalliax mcilhennyi Felder &amp; Manning, 1994.</p> <p>Differences between Calliax and Eucalliax (figures from Felder &amp; Manning 1994 for Eucalliax mcilhennyi) species are: 1) A1 peduncle is distinctly shorter than that of A2, not overreaching the proximal border of the last article in Calliax (reaching mid-length of last article in Eucalliax); 2) Mxp3 is subpediform in Calliax (Fig. 17K, L) (operculiform in Eucalliax [Fig. 18P]); 3) P1 is unequal; the minor with the fixed finger shorter than and separated from the dactylus by a wide gap, bearing a large triangular proximal tooth in Calliax (Fig. 17D, E) (P1 is subequal and similar in Eucalliax, Fig. 18M, N); 4) male Plp2 has an appendix masculina (Fig. 18D), female Plp2 lacking an appendix interna in Calliax (Fig. 18B) (male Plp2 has both appendix interna and appendix masculina [Fig. 18L] female Plp2 often with appendix interna in Eucalliax, Fig. 18J); 5) the telson is less than 1.5 times as wide as long with the posterior border straight or slightly convex and no dorsal transverse carina in Calliax (Fig. 17J) (the telson is over 1.5 times as wide as long with the posterior border straight or slightly concave with the dorsal transverse carina often present in Eucalliax [Fig. 18O]); and 6) the uropods are about as long or slightly longer than the telson in Calliax (Fig. 17J) (uropods are long- er with the endopod overreaching the telson by at least half of its length in Eucalliax [Fig. 18O]).</p> <p>Calliax lobata (de Gaillande &amp; Lagardère, 1966) (Figs 17; 18)</p> <p>Callianassa (Callichirus) lobata de Gaillande &amp;</p> <p>Lagardère, 1966: 259, pls 1-4.</p> <p>Calliax lobata – de Saint Laurent 1973: 514. — de</p> <p>Saint Laurent &amp; Božić 1976: 28, figs 7, 15, 23, 27,</p> <p>34. — Thessalou-Legaki &amp; Zenetos 1985: 311. —</p> <p>°Thessalou-Legaki 1986: 183. — Manning 1987:</p> <p>397. — Števčić 1985: 313; 1990: 218. — Manning &amp;</p> <p>Felder 1991: 783, figs 15f-j. — ° Froglia 1995: 7. —</p> <p>Falciai &amp; Minervini 1996: 145, 4 figs. — Sakai 1999a:</p> <p>110, fig. 27a-c. — d’Udekem d’Acoz 1999: 155. —</p> <p>Tudge et al. 2000: 145, figs 3, 4 (cladogram). —</p> <p>° Türkay 2001: 289.</p> <p>TYPE MATERIAL. — Holotype: #, Port-Miou, near</p> <p>Toulon, France, de Gaillande coll., X.1964 (MNHN</p> <p>Th 1296); paratypes: # 1 (MNHN Th 1298), 1,</p> <p>1 (MNHN Th 84), 1, 1 (RMNH D 23011) (# previously deposited in the Station marine d’Endoume, France).</p> <p>MATERIAL EXAMINED. — France.

The gender is feminine.</p> <p>DIAGNOSIS. — Carapace lacking dorsal oval, with transverse suture posterior to cervical groove. Rostrum broadly triangular with pointed tip or small rostral spine, pointed lateral projection on either side. Second abdominal segment largest, slightly larger than sixth, lateral tufts of setae present on segments 3-5. Telson approximately 1.2-1.6 times as wide as long, lateroposterior angles rounded, posterior border straight or slightly concave in median part.</p> <p>Eyestalk weakly flattened dorsoventrally; cornea diskshaped. A1 peduncle shorter than that of A2. Mxp1 endopod elongate, epipod large, tapering distally. Mxp2 with bilobed epipod and single arthrobranch. Mxp3 operculiform, propodus with lower border strongly expanded proximally, dactylus rounded, exopod present.</p> <p>P1 equal and similar; P3 with heel on proximal lower border. P4 propodus linear.

Male Plp2 biramous with appendix interna and appendix masculina. Female Plp1 uniramous, female Plp2 biramous with finger-like appendix interna. Plp3-5 biramous, foliaceous, appendix interna finger-like, sitting side by side with mesial border of endopod. Uropodal endopod overreaching telson by about half its length; dorsal plate on exopod with distal setal row well apart from rounded posterior border.</p> <p>REMARKS</p> <p>Differences between the genera Calliax, Calliaxina n. gen. and Paraglypturus, based on their type species Calliax lobata, Calliaxina punica n. comb. and Paraglypturus calderus Türkay &amp; Sakai, 1995 are presented in Table 1.</p> <p>De Saint Laurent &amp; Manning (1982) stated that Calliax lobata and Calliaxina punica n. comb., both from the Mediterranean, were significantly different. They actually differ, as listed above, by many characters, the most important of which concern the morphology of the Mxp3, the P1, and also the male and female Plp1, Plp2.</p> <p>Calliaxina n. gen. and Paraglypturus (Fig. 20 K- O) (see also Türkay &amp; Sakai 1995: figs 2-6) are similar in having an exopod on the Mxp3 but the ischium-merus shape differs (operculiform in Calliaxina n. gen., Fig. 19K, subpediform in Paraglypturus, Fig. 20K). Other discrepancies are: 1) the pointed rostrum and anterolateral projections are present in Calliaxina n. gen. (Fig. 19A, E) (absent in Paraglypturus); 2) Mxp2 is with arthrobranch in Calliaxina n. gen. (without in Paraglypturus); 3) P1 are subequal, similar, laterally compressed in Calliaxina n. gen. (Fig. 19C) (unequal, dissimilar, not compressed in Paraglypturus); 4) male Plp1 bears an appendix interna in Calliaxina n. gen. (Fig. 20C) (not in Paraglypturus, Fig. 20M); 5) the appendix interna on Plp3-5 is digitiform in Calliaxina n. gen. (Fig. 20G) (stubby in Paraglypturus, Fig. 20Q); and 6) the uropodal endopod overreaches the telson for at most half of its length in Calliaxina n. gen. (Fig. 19D) (it is much longer in Paraglypturus).</p> <p>Paraglypturus calderus material was taken from hydrothermally influenced sediments of the Mariana Arc. This is an environment of hot water (porewater temperature of over 50°C) and shallow depth (64-114 m) (Türkay &amp; Sakai 1995). Besides characters shown above in comparison with Calliaxina n. gen., this species displays a few others of unknown significance (Türkay &amp; Sakai 1995: figs 3, 6): 1) eyestalks are weakly flattened dorsoventrally with prominent, globulous, subterminal, well pigmented corneas; 2) the uropodal endopod in large males and females bears a yellow transparent circular structure on lower plate; and 3) eggs are small (0.2 mm in diameter) and attached to the Plp1 only in most females (seven/ eight females), larger (0.5 mm in diameter) and attached to Plp 1- 5 in one female (Türkay &amp; Sakai 1995: 29). Eggs are also few (less than 10 per female in sample SMF 22949 including three females).</p> <p>Considering the morphological dissimilarities alone, differentiation between Calliaxina n. gen. and Paraglypturus seems justified. Paraglypturus calderus, nevertheless, shares with members of Callianassidae, and the Eucalliacinae in particular, many characteristics: 1) absence of a dorsal oval on the carapace; shape of eyestalks; 2) A1 peduncle shorter than that of A2; 3) Mxp3 propodus and dactylus ovate; 4) appendix masculina present on male Plp2; and 5) a dorsal plate present on the uropodal exopod. Its remote position in Tudge et al. ’s (2000) cladogram as the sister taxon of all other callianassids is enigmatic.</p> <p>Callianassa tooradin Poore &amp; Griffin, 1979 was placed in Paraglypturus by Sakai (1999a). It shares similarities (see Poore &amp; Griffin 1979: fig. 36) with Paraglypturus calderus in: 1) absence of a pointed rostrum and anterolateral projections on the carapace; 2) subpediform Mxp3 with exopod; 3) P1 unequal; 4) appendix interna absent from male Plp1; and 5) uropods much longer than the telson. There are differences: 1) small eye corneas instead of large, globulous; 2) minute Mxp1 endopod instead of elongate; 3) arthrobranch present on Mxp2; and 4) appendix masculina absent from male Plp2. Nevertheless, the similarities listed above, the morphology of Mxp3 especially, link the two species. It is proposed here that Paraglypturus tooradin (Poore &amp; Griffin, 1979) provisionally remains in that genus as suggested by Sakai pending additional material for study in future.</p> </div>	https://treatment.plazi.org/id/03FF2C63FFA9FFAA2F3D7DD2FC5D77DB	Public Domain	No known copyright restrictions apply.

Telson about as long as proximal width; lateral borders parallel in proximal third, converging distally to straight or convex posterior border. A1 peduncle not overreaching that of A2. Mxp1 endopod elongate, epipod large, truncate anteriorly. Mxp2 with small epipod. Mxp3 pediform, with exopod; ischium with prominent toothed crest on mesial surface; lower distal margin of merus unarmed or with spines. Both major and minor P1 with proximal lower spine on merus; minor P1 with palm tapering distally. P2 fixed finger and dactylus with cutting edge unarmed or bearing teeth.

Female Plp1 uniramous, female Plp2 biramous, foliaceous with finger-like appendix interna. Plp3-5 biramous, foliaceous, with finger-like appendix interna sitting side by side with mesial border of endopod. Uropods about as long as telson; exopod without dorsal plate, posterior bor- der with or without notch.</p> <p>REMARKS</p> <p>Gourretia currently includes eight species, as list- ed in Tudge et al. (2000):</p> <p>– G. barracuda Le Loeuff &amp; Intès, 1974;</p> <p>– G. biffari Blanco Rambla &amp; Linero Arana, 1994;</p> <p>– G. coolibah Poore &amp; Griffin, 1979;</p> <p>– G. crosnieri Ngoc-Ho, 1991;</p> <p>– G. denticulata (Lutze, 1937), type species;</p> <p>– G. lahouensis Le Loeuff &amp; Intès, 1974;</p> <p>– G. laresi Blanco Rambla &amp; Linero Arana, 1994; – G. manihinae Sakai, 1984.</p> <p>Manning &amp; Felder (1991) as well as Tudge et al. (2000) mentioned three differentiating characters for the above species: 1) rostrum straight or (slightly) upturned; 2) lower distal margin of Mxp3 merus unarmed or with spine; and 3) posterior border of uropodal exopod with or without notch. Two others can be added: 4) and 5) minor P1 and P2 with or without teeth on cutting edge of fixed finger and dactylus. None of them however permits a clear species grouping. Considering two examples, on basis of characters 1-3 only, for simplification, it can be noted that: 1) both G. biffari and G. laresi have an upturned rostral spine and a distal spine on the Mxp3 merus, but a notch on the uropodal exopod is present in the former, absent in the latter; and 2) like G. laresi, three other species, G. barracuda, G. denticulata and G. manihinae, bear a distal spine on the Mxp3 merus and no notch on the uropodal exopod, but they differ from G. laresi by having a straight rostral spine. These differences are regard- ed here as specific variations.</p> <p>By contrast, the diagnostic characters cited above link members of the genus. The following are most significant: 1) Mxp1 bears an elongate endopod and a large epipod truncate anteriorly; 2) Mxp3 is pediform, with exopod and a prominent toothed crest on mesial surface of ischium; 3) both major and minor P1 have a lower proximal meral spine; 4) minor P1 with the palm tapering distally; 5) the morphology of male and female Plp1, Plp2; 6) the shape of telson with lateral borders parallel proximally and converging distally to the posterior border; and 7) uropods are about as long as the telson, the exopod without a dorsal plate. These clearly define the genus.</p> <p>Several similarities exist between members of Gourretia and Dawsonius latispina (Dawson, 1967), type species of the genus Dawsonius Manning &amp; Felder, 1991. The grouping of the genera Gourretia and Dawsonius in a subfamily Gourretinae, as proposed by Sakai (1999b), seems justified.</p> <p>Gourretia denticulata (Lutze, 1937) (Fig. 21)</p> <p>Callianassa subterranea var. minor Gourret, 1887: 1034; 1888: 96, pl. 8, figs 1-15.</p> <p>Callianassa denticulata Lutze, 1937: 6, figs 1-7; 1938: 170.</p> <p>Gourretia serrata de Saint Laurent, 1979: 79. — Thessalou-Legaki &amp; Zenetos 1985: 311. — °Thessalou- Legaki 1986: 184. — °Pancucci-Papadopoulou et al. 1999: 393.</p> <p>Callianassa (Cheramus) subterranea var. minor – Pesta 1918: 205 (part).</p> <p>Callianassa (Cheramus) minor – de Man 1928 b: 26, 100.

It was first described by Gourret (1887) as Callianassa subterranea var. minor, and was later placed by de Saint Laurent (1973: 514) in a separate genus, Gourretia, for which it was made type species. In 1979, de Saint Laurent (1979: 79) reported that the name Callianassa subterranea minor Gourret, 1887 was a junior primary homonym of Callianassa minor Fischer, 1866, a fossil species from the Miocene of southern France. At the same time, a replacement name, Gourretia serrata nom. nov. was proposed for the species. De Saint Laurent overlooked however another available name that was Callianassa denticulata Lutze, 1937 which species de Saint Laurent &amp; Božić (1976: 27) had previously synonymised with Callianassa minor.</p> <p>This taxonomic question was settled by Lewinsohn &amp; Holthuis (1986: 24) and the name Gourretia denticulata (Lutze, 1937) has been used thereafter.</p> </div>	https://treatment.plazi.org/id/03FF2C63FFA4FFA32EE17BF2FEB077DB	Public Domain	No known copyright restrictions apply.

Md (Fig. 24E) without mesio-anterior tooth.</p> <p>P1 slender in young male and female, with small fixed finger (Fig. 25 A-C), stouter and with much shortened fixed finger in large male (Fig. 24F, G). Ischium with spine on lower border. Merus with upper subdistal spine, eight to 10 spines and three to five spinules on lower border. Carpus with several spinules on upper border; three large upper mesial distal spines and lower distal spine. Propodus with three or four longitudinal rows of spines on mesial surface; large lower spine posterior to fixed finger followed by smaller one; fixed finger short or very short, unarmed. Dactylus with tubercles on upper border and a few others on mesial surface.</p> <p>P2 (Fig. 25D) merus with upper subdistal spine, two to four lower spinules; carpus with four or five upper spines and lower subdistal spine, propodus with upper proximal spine.

Largest specimens in material examined: cl. 18- 21 mm, tl. 54-59 mm. Largest size reported: tl. up to 80 mm or exceptionally 150 mm (Moyse &amp; Smaldon 1990).</p> <p>ECOLOGY AND BIOLOGY</p> <p>The population ecology of the species in western Sweden was studied by Tunberg (1986). In western Norway, it occurs in shell and mineral sand with some mud, at 3 m depth (Samuelsen 1974), in shallow water in southern part of the boreal region (Christiansen 2000). It was found in muddy-gravel association off Plymouth, English Channel (Holme 1966), and was occasionally dredged from mud or muddy sand (Gordon 1957). It is common in Brittany, France, in coarse or muddy sand, with or without seagrass (d’Udekem d’Acoz 1989). Specimens were collected from shore, in Ireland (Selbie 1914), near the water edge on the beach (Southern 1915), between 20-40 m, in Portugal (Neves 1990), and were present in a variety of substrates from sand with high percentage of pebbles to muddy sand, in Patras Gulf, Greece, at 5-15 m depth (Thessalou-Legaki &amp; Zenetos 1985).</p> <p>Reproduction occurs in February-April in Roscoff, France (Bourdon 1965) in spring and summer in Plymouth, UK (Gordon 1957). Larvae are present in Roscoff during February- November, abundant in July-August, mainly near the bottom (i.e. at 15 m depth in a bottom of 20 m) during day time, in surface waters at night (Thiriot 1976), common in the Kilkieran Bay plankton, Ireland in April-October, plentiful in August (O’Céidigh 1962).</p> <p>Aspects of biology studied</p> <p>Functional anatomy of foregut (Ngoc-Ho 1984); branchial parasitic isopods (Astall et al. 1996); burrow morphology and burrow-dwelling lifestyle (Astall et al. 1997a); branchial morphology, gill area and gill ultrastructure (Astall et al. 1997b); particle size selectivity and resource partitioning (Pinn et al. 1998b); burrows in scottish mearl beds (Hall-Spencer &amp; Atkinson 1999); gut morphology and gut microflora (Pinn et al. 1999a); mouthpart morphology and mouthpart setal fringes (Pinn et al. 1999b); functional response in filter feeding (Lindahl &amp; Baden 1997); oxygen transporting properties of heamocyanin (Taylor et al. 2000).</p> <p>VARIATIONS</p> <p>There are variations in: 1) the rostrum often bears two, three or (rarely) four lateral rostral teeth; 2) the large upper distal spine on P1 carpus is sometimes accompanied mesially by one or two spinules (Fig. 26F); 3) the lower border of P1 propodus has two to five spinules on the proximal half, three on the left and eight (rare) on the right in the holotype (Fig. 26E); 4) the distal lateral spine, as well as distal mesial spine near the base of P1 fixed finger, is larger in female than in male, and impaired, as on left P1 of holotype (rarely paired as on right P1 of holotype, Fig. 26E, F); 5) P1 fixed finger is about as long as the dactylus in small specimens (cl. 7-8 mm, tl. c. 20-22 mm), shorter than the dactylus in most large specimens, shortest in large males; and 6) P3 merus is sometimes unarmed.</p> <p>REMARKS</p> <p>Upogebia deltaura is close to U. mediterranea Noël, 1992 which is often associated with Posidonia oceanica seagrass. Some materials assigned to U. deltaura and reported as associated with Posidonia (Harmelin 1964; Pérès &amp; Picard 1964) could actually belong to U. mediterranea. Differentiation of U. deltaura and U. mediterranea is discussed under the latter species.</p> <p>U. deltaura is similar to U. demani de Saint Laurent &amp; Le Loeuff, from the Gulf of Guinea, in the shape and spinulation of the rostrum (de Saint Laurent &amp; Le Loeuff 1979: 41, fig. 4b), also in having a lower spine on article 3 of A2 peduncle. De Saint Laurent &amp; Le Loeuff (1979: 42, fig. 4a) fail to mention and figure the latter character, but give in detail the differences between the two species.</p> <p>The pointed postero-ventral pleura of abdominal segment 1 is the most important characteristic of U. deltaura. Along with the morphology of the rostrum and the unarmed antero-lateral border of the carapace, it permits a quick identification even of small specimens (e.g., MNHN Th 1324; cl. 3.5 mm). The carapace is thin and weakly calcified in some specimens.</p> <p>Genital openings are visible in young male and female of cl. 5-5.5 mm (tl. c. 15-17 mm) but Plp1 appear at a later stage in female of cl. 6.5- 8 mm (tl. c. 19-22 mm).</p> <p>Upogebia deltaura, widely distributed in Europe, was also found in Western Africa (Ivory coast and Togo) by Le Loeuff and Crosnier (MNHN Th 283, 284, 663, 668, 670). Specimens from these areas are apparently smaller than in Europe, but the adult size is not known as no ovigerous females were available for study.</p> <p>Upogebia mediterranea Noël, 1992 (Figs 28; 29)</p> <p>Upogebia n. sp. “ mediterranea ” Noël, 1992: 82.</p> <p>Upogebia deltaura –?

Burrows in firmground were studied by Asgaard et al. (1997).</p> <p>VARIATIONS</p> <p>1) The upper mesial distal spine of P1 carpus is accompanied laterally by one to three spinules; 2) the longitudinal row of tubercles on the lateral and mesial sufaces of the dactylus, as well as the proximal mesial round tooth on cutting edge is sometimes faint or absent (rare); and 3) arthrobranchs are composed of a single row of lamellae on either side of the rachis in specimens from the Gulf of Gabès, Tunisia, and a double row of lamellae in the rest of the material examined.</p> <p>D</p> <p>REMARKS</p> <p>This species, similar to both U. deltaura and U. nitida, was first mentioned by de Saint Laurent &amp; Le Loeuff (1979: 93) as an undescribed species related to U. nitida.</p> <p>According to Dworschak (1992: 223), it was cited again, under the present name mediterranea, as a taxon related to U. deltaura, by de Saint Laurent in a key to western Atlantic and Mediterranean species of Upogebia (“Tableau de détermination des Upogebia de l’Atlantique nordoriental et de Méditerranée”). This key was given to participants of the IInd Colloquium Crustacea Mediterranea in Ancona, Italy (1979) but was never validly published. The species was subsequently recognized by Kocata ș (1981), Thessalou-Legaki &amp; Zenetos (1985) and Thessalou-Legaki (1986). It was mentioned by Noël (1992) in an identification key to decapod crustaceans from France and common European species (“Clé préliminaire d’identification des Crustacea Decapoda de France et des principales autres espèces d’Europe”). As Noël’s key was published and contained diagnostic details, Noël is now the species’ author according to the International Code of Zoological Nomenclature (ICZN 1999). The type series includes all specimens examined by him or de Saint Laurent before the species name was published. They were considered as syntypes and a lectotype was selected from them.</p> <p>Upogebia mediterranea resembles U. deltaura in: 1) the shape and armature of the rostrum; and 2) the anterolateral border of carapace unarmed. It differs in the following characters: 1) the pleura of the first abdominal segment is rounded postero-ventrally in U. mediterranea (pointed in U. deltaura); 2) A2 peduncle is unarmed in U. mediterranea (with a lower distal spine on article 3 in U. deltaura); 3) P1 merus bears spinules and/or tubercles on its lower border in U. mediterranea (with spines and spinules in U. deltaura); 4) P1 propodus has no mesial distal spine near the base of the fixed finger in U. mediterranea (spine present in U. deltaura); 5) P1 dactylus bears a proximal mesial round tooth on the cutting edge in U. mediterranea (tooth often absent in U. deltaura); 6) P1 dactylus and fixed finger are of about the same length in U. mediterranea (dactylus often longer than fixed finger in U. deltaura); 7) P3 merus is unarmed in U. mediterranea (with spinules and tubercles on the lower border in U. deltaura); and 8) the telson is approximately quadrate in U. mediterranea (about 1.2 times as wide as long in U. deltaura).</p> <p>Upogebia mediterranea was considered closely related to U. nitida (A. Milne-Edwards, 1868) by de Saint Laurent &amp; Le Loeuff (1979: 39, 93) and d’Udekem d’Acoz (1999: 157) or a subspecies of the latter (d’Udekem d’Acoz 1995). It was actually confused with the U. nitida in Le Loeuff &amp; Intès (1974: 58, fig. 20). The small female these authors reported from Congo, of 5.5 mm in carapace length, and now deposited in the MNHN (MNHN Th 231), actually belongs to U. mediterranea. The excellent figures given agree perfectly with those of the latter species (Figs 28; 29), but with neither U. nitida (Figs 30; 31) nor U. furcata (Aurivillius, 1898) (see Le Loeuff &amp; Intès 1974: fig. 18), a common species in the area. This female, bearing a large coxal spine on both P1 and P2, represents the only record of U. mediterranea outside the Mediterranean.</p> <p>More likeness can be found between U. mediterranea and a newly established, non-european species, U. senegalensis Ngoc-Ho, 2001 from Senegal. The latter resembles both U. mediterranea and U. nitida and the three are sometimes hard to differentiate.</p> <p>Similarities and differences between U. mediterranea and U. senegalensis are presented below with some details and summerised in Table 2. U. mediterranea and U. senegalensis are compared with U. nitida under the latter species and summerized in the same table.</p> <p>U. mediterranea resembles U. senegalensis (see Ngoc-Ho 2001a: figs 1-3) in: 1) the shape of rostrum; 2) the shape and spinulation of P1 except for a subdistal tooth absent on dactylus cutting edge; and 3) an acute coxal spine on both P1 and P2.</p> <p>It differs from U. senegalensis in: 1) the large A2 scale with pointed tip (small A2 scale with blunt tip in U. senegalensis); 2) absence of subdistal tooth on the cutting edge of P1 dactylus (tooth present in U. senegalensis); 3) P2 bears a dorsal subdistal spine on both merus and carpus (P2 unarmed in U. senegalensis); and 4) the telson is subquadrate (telson slightly wider than long in U. senegalensis).</p> <p>Upogebia nitida (A.

According to Pesta (1918), Bouvier (1940), Zariquiey Alvarez (1968), Upogebia pusilla can be found as far north as Norway, the North Sea while according to Poulsen (1941), the species was absent from Norway. More recently, Moyse &amp; Smaldon (1990) considered the distribution of Upogebia pusilla to include the British Isles, probably only the South. In this work, a male from the English coast of the English Channel has been found (NHML 2002.839).</p> <p>The southernmost localities of the species distribution in Eastern Atlantic (Mauritania and Sao Thomé) were given by a single female of cl. 13 mm (tl. 43 mm) collected in 1965 and a male of cl. 14 mm (tl. 45 mm), collected in 1889. Both are in fair condition, but it is questionable whether the label accompanying the specimen from Sao Thomé is authentic.</p> <p>The species is common around the Mediterranean and is also found in the Black Sea (Makarov 1938) and the Suez Canal (Monod 1937).</p> <p>DIAGNOSIS</p> <p>Rostrum (Fig. 32A, B) obtuse distaly, about 1.2- 1.3 times as long as wide at base, with four or five teeth on lateral border; anterolateral border of carapace with spine; telson (Fig. 32H) approximately 1.2-1.3 times as wide as long, distal margin narrower than proximal, posterior border straight or slightly concave medially.</p> <p>A1 and A2 peduncle (Fig. 32B) with spine on lower margin of article 1 and 3 respectively; A2 scale with distal spine. Md with large mesio-anterior pointed tooth. Mxp1 without epipod, Mxp3 with epipod.</p> <p>P1 stouter in male (Fig. 32C, D) than in female (Fig. 32F, G). Ischium with two to four spines on lower border. Merus with upper subdistal spine, three to six spines and spinules on proximal half of lower border and a double or single row of denticles distally. Carpus with large upper mesial distal spine and lower distal spine. Propodus more slender in female, dilated distally in large male (cl.&gt; 11.5- 12 mm); upper border with lateral longitudinal smooth crest and mesial crest bearing tubercles or denticles (Fig. 32E); small mesial upper subdistal spine, large mesial upper distal spine; both lateral and mesial surfaces with distal spine near cutting edge of dactylus; fixed finger shorter than dactylus, cutting edge smooth or with small teeth on proximal half. Dactylus 2.5-4 times as long as fixed finger, cutting edge with round teeth.</p> <p>P2 (Fig. 33A) with upper subdistal spine and one to three lower spines on merus; carpus with upper and lower distal spine. P3 (Fig. 33B) with three or four lower spines on merus, carpus with lower distal spine. Small coxal spine on P1 and P2. Basipod of uropod with spinule hanging over endopod; exopod (Fig. 32G, H) triangular, about as long as distal width, with proximal spinule.</p> <p>Colour</p> <p>Usually dull green, sometimes brown (d’Udekem d’Acoz pers. comm.).</p> <p>Variable, blueish to greenish-brownish (Dworschak pers. comm.); a coloured photograph is presented in Geiss (1990).</p> <p>Size</p> <p>Large specimens in material examined: cl. 15.5- 18 mm, tl. 47-50 mm. In Northern Adriatic: males are of cl. 20-22 mm, tl. 55-61 mm, females of cl. 16-18 mm, tl. 46-52 mm, with a maximum size of 66 mm in males and 60 mm in females; males of tl.&gt; 50 mm have a longer carapace than females of the same size (Dworschak 1988). Largest size reported, from North Aegean Sea: 82 mm for females, 106 mm for males (Kevrekidis et al. 1997).</p> <p>BIOLOGY AND ECOLOGY</p> <p>The biology of U. pusilla in the Bay of Chingoudy (Pays Basque), France was reported by Chaud (1984a, b). Its biology in Northern Adriatic, including burrow construction, environment, growth and production, feeding, pumping rate, was studied in detail by Dworschak (1981, 1983, 1987a, b, 1988).</p> <p>In the Patra Gulf and Ionian Sea (Greece), this species was found living in a wide range of substrates with little or no mud, in shallow water; it was absent from Posidonia meadows (Thessalou- Legaki &amp; Zenetos 1985). In Trébeurden, Brittany, many specimens were found at 20- 25 cm depth, in an area with muddy sand and small Zostera (d’Udekem d’Acoz 1986), and also in coarse sand. They were dark green or brown coloured and may carry the parasitic isopod Gyge branchialis Cornalia &amp; Panceri, 1861 (Tucker 1930; d’Udekem d’Acoz 1989). In Marseille, France, U. pusilla was regarded as the characteristic species of biocoenoses with muddy sand, in shallow and calm water (Pérès &amp; Picard 1964; de Gaillande 1968).</p> <p>Other aspects of biology studied</p> <p>Branchial morphology, gill area and gill ultrastructure (Astall et al. 1997b); population dynamics, reproduction and growth (Kevrekidis et al. 1997); comparison of gut morphology and gut microflora (Pinn et al. 1999a); mouthpart morphology and mouthpart setal fringes (Pinn et al. 1999b); abundance of population in Corsica (de Vaugelas 1991); relation between burrow architecture, feeding mode and structure of the sediments (de Vaugelas 1998).</p> <p>VARIATIONS AND REMARKS</p> <p>Upogebia pusilla is the most common European upogebiid species but varies morphologically. Variation is greatest among Mediterranean populations and bring them near an allied species in the area, U. tipica (Nardo 1869). The two are sometimes so similar or hardly distinguishable that García Raso (1983), studying material from southern Spain, thought they might be identical. Examination of the present material reveals however that both species are valid, and their differentiation is discussed under U. tipica.</p> <p>Most characteristics given to U. pusilla by authors such as de Man (1927), Bouvier (1940), de Saint Laurent (1971) concern P1 propodus, e.g., the distal dilation, the length/width ratio or the spinulation of its upper margin, but these are variable, as reported by García Raso (1983), and Dworschak (1992).</p> <p>Characteristics of typical U. pusilla as listed in the diagnosis fit best specimens from the Atlantic, and some from the western Mediterranean.</p> <p>Certain variations mentioned by García Raso (1983), affecting few specimens, can be consider- ed as usual within large populations; they are: 1) paired or bifid postocular spine on anterolateral border of carapace (usually single); 2) bifid A2 scale (usually simple); and 3) lateral distal border of P1 carpus with two or three spinules (one usually).</p> <p>Other variations occur more often, mainly in the rostrum and P1:</p> <p>The rostrum is between 1.2-1.4 times as long as wide at base.</p> <p>P1 propodus: 1) the length/width ratio varies between 1.7-2.65 in male, 2.15-2.8 in female, 2.8-3.7 in juvenile (García Raso 1983); 2) the mesial longitudinal crest on the upper margin is sometimes armed with spines (Fig. 33E, G); 3) both the lateral and mesial crests on the upper margin are sometimes very faint; 4) the distal dilation at level of the fixed finger is nearly absent in female, weak in young male, pronounced in large male; 5) the median spine on the mesiodistal margin (near the cutting edge of the dactylus) is large in female (Fig. 32G), much smaller or absent in male (Fig. 32D); 6) the fixed finger is distal in female, slightly or strongly subdistal in male; 7) the fixed finger is about one-fourth to half as long as the dactylus; and 8) the dactylus and fixed finger cutting edge is unarmed or with small teeth.</p> <p>The following characters which contrast with U. tipica, are more constant (the last one to a lesser extent): 1) the rostrum is less than 1.5 times as long as wide at base with four or five teeth on each lateral border; 2) P1 merus bears three to six spines and spinules on the proximal half of the lower margin, and denticles distally; 3) P1 propodus has a longitudinal upper smooth crest on the lateral surface, an upper longitudinal tuberculate or spinous crest on the mesial surface, an upper subdistal spine, an upper distal spine and a median distal spine near the cutting edge of dactylus (in females especially); and 4) the telson is wider than long, the uropodal exopod is triangular and about as long as its distal width, this appendage is slightly longer in juvenile.</p> <p>Upogebia stellata (Montagu, 1808) (Figs 34; 35)</p> <p>Cancer Astacus stellatus Montagu, 1808: 89, tabl.

Largest specimens in material examined: cl. 14-16 mm, tl. 41-49 mm.</p> <p>ECOLOGY AND BIOLOGY</p> <p>In Gullmarfjord, Sweden, the species was found in a bottom of clay, sand and gravel, at 25-30 m depth (Gustafson 1934). It was less common in the North Sea than U. deltaura but was found in nearly the same localities (Adema et al. 1982). In western Norway, it was collected on the littoral, at low water, in mineral sand with some mud, or in shell sand, at 7-13 m; one specimen was found in mud at 120 m (Samuelsen 1974). It was recorded in shallow water in southern part of the boreal region (Christiansen 2000), collected between 25-36 m in Danish waters (Poulsen 1941) and was rare in the Clyde sea area (Allen 1967). It is common on all coasts of the British Isles (Moyse &amp; Smaldon 1990); fairly common around Roscoff, France, in the same intertidal areas as U. deltaura, but less abundant (Bourdon 1965). According to Holme (1966), it lives in a muddy-gravel substrate, off Plymouth, English Channel. Reproduction occurs in February- August in Roscoff (Bourdon 1965). Larvae are abundant in Roscoff from February to July, with the same distribution as U. deltaura (Thiriot 1976).</p> <p>Aspects of biology studied</p> <p>Burrow morphology and feeding behaviour (Nickell &amp; Atkinson 1995); branchial parasitic isopods (Astall et al. 1996); burrow morphology and burrow-dwelling lifestyle (Astall et al. 1997a); branchial morphology, gill area and gill ultrastructure (Astall et al. 1997b); microbial flora associated with digestive system (Pinn et al. 1997); morphology of mouthparts and pereiopods in relation to feeding, ecology and grooming (Nickell et al. 1998); diet (Pinn et al. 1998a); particle size selectivity and resource partitioning (Pinn et al. 1998b); gut morphology and gut microflora (Pinn et al. 1999a); mouthpart morphology and mouthpart setal fringes (Pinn et al. 1999b); oxygen transporting properties of heamocyanin (Taylor et al. 2000).</p> <p>REMARKS</p> <p>With an exception, the southernmost distribution of this species in the material examined, is Brittany, northwest France. Several samples collected in southwest France (Arcachon), Spain or Portugal and previously assigned to U. stellata, are actually U. pusilla. The possible exception is the material from Greece reported by Thessalou- Legaki (1986). It includes a small female (cl. 9 mm) from Orei Channel and two P1 of a very small and badly damaged specimen (not examin- ed) from Rhodes. The female from Orei differs from typical U. stellata by having no pleurobranchs on P5 of both sides, and by the uropods distinctly longer than the telson. It could possibly belong to U. stellata in virtue of the shape of the rostrum, the posterior border of telson medially concave and a median distal spine on mesial surface of the P1 carpus. This is the only possibly correct record of this species (with variations) in the Mediterranean. Nobre (1931, 1936) reported U. stellata from Portugal, with a figure representing, with little doubt, a specimen of U. pusilla. Bonnier (1887) and Vilela (1936) reported U. stellata from the Bay of Concarneau, France and from Faro, Portugal respectively; their materials have not been checked. More recently, Lacourt (1977) considered U. stellata as part of the marine fauna of the Bay of Concarneau. Specimens he studied were deposited (dried) in the Rijksmuseum of Natural History, Leiden, and one of these (RMNH D 45673) has been examined. It actually belongs to U. pusilla.</p> <p>U. stellata was often confused with U. deltaura and a part of the material studied by Grieg as U. stellata (1927, with a figure) is likely U. deltaura. De Morgan (1910) revealed the distinction between the two species in the anterolateral border of the carapace, with a spine in U. stellata, unarmed in U. deltaura. Also the P1 fixed finger is half as long as the dactylus in the former species, as long or nearly as long as the dactylus in the latter.</p> <p>Upogebia stellata has also been confused with U. pusilla and U. tipica, for all three have a spine on the antero-lateral border of the carapace, a subcheliform P1 and like P2 and P3.</p> <p>It can readily be differentiated from U. pusilla and U. tipica, as well as all other European Upogebia, in having a pleurobranch on the P5. Additional distinguishing features are: 1) P1 carpus has a median spine on its mesial distal border and the dactylus bears an upper proximal conical tooth (spine and tooth absent in U. pusilla and U. tipica); and 2) the telson is about 1.5 times as wide as long with lateral borders regularly curved and the posterior border slightly concave medially (it is 1.3 times as wide as long or approximately quadrate in U. pusilla and U. tipica respectively with lateral borders convex and the posterior bor- der straight).</p> </div>	https://treatment.plazi.org/id/03FF2C63FFDAFFFC2D1079F3FE947299	Public Domain	No known copyright restrictions apply.

Md with large mesio-anterior pointed tooth. Mxp1 without epipod, Mxp3 with epipod.</p> <p>P1 slightly stouter in male (Fig. 36E, F) than in female (Fig. 36C, D). Ischium with one or two spines on lower border. Merus with upper subdistal spine, seven to 12 spines on two-thirds or whole lower margin and spinules distally. Carpus with mesial upper distal spine and lower distal spine. Propodus slender, about 2.5-4 times as long as wide; lateral surface with median distal spine near cutting edge of dactylus; mesial surface with row of two to five upper spines including subdistal one and upper distal spine near articulation with dactylus; cutting edge of fixed finger smooth or with small denticles. Dactylus 2.5-4 times as long as fixed finger, cuting edge smooth or with round teeth.</p> <p>P2 (Fig. 37H) with upper subdistal spine, one or two lower spinules on merus; carpus with upper and lower distal spine. P3 (Fig. 37I) with one to three lower spines on merus; carpus with lower distal spine. Small coxal spine on P1 and P2. Basipod of uropod (Fig. 36G, H) with spinule hanging over endopod; exopod 1.3-1.5 times as long as distal width, with proximal spine.</p> <p>Colour</p> <p>Similar to U. pusilla, with small spots of brownish red (Dworschak pers. comm.).</p> <p>Size</p> <p>Largest specimens in material examined: cl. 12- 14.5 mm, tl. 35-42 mm.</p> <p>ECOLOGY</p> <p>In the Adriatic, U. tipica prefers muddy bottoms below 9 m (Dworschak 1992). In the Patras Gulf, it was found in substrates with high percentages of mud and also in Posidonia meadows (Thessalou- Legaki &amp; Zenetos 1985). It was collected from the infralittoral zone, in the Evvoia coast and Evvoia Gulf, at 5-50 m depth, in a bottom consisting of mud or mud mixed with sand (Kattoulas &amp; Koukouras 1974). Abundant populations are found near Banyuls, at 25-30 m depth, in bottom with sand or grit (Amouroux pers. comm.).</p> <p>Its burrow structure on Squilla grounds was reported by Atkinson et al. (1998), also by Dworschak (1987c: pl. 3, fig. 11).</p> <p>VARIATIONS AND REMARKS</p> <p>This species, so far reported from the Mediterranean only, presents certain variations and the first two are more pronounced between populations from the eastern and western part: 1) the length and spinulation of rostrum (it is longer and with more teeth in eastern specimens); 2) P1 slenderness (the ratio of the propodus length/width is 3-4 in the east, 2.5- 3 in the west); 3) P1 propodus is sometimes with a lateral longitudinal smooth crest near the upper border; 4) or with spinules among the mesial upper spines (Fig. 37G); 5) the lower distal spine is exceptionally missing on the left P1 carpus of U. gracilipes type (MNW 304, Fig. 37A, B) and present on the right appendage; 6) the dactylus and fixed finger cutting edge is unarmed or bearing small teeth; and 7) the uropodal exopod has a lateral distal spinule or lacks it.</p> <p>Upogebia tipica and U. pusilla are similar in having: 1) the antero-lateral border of carapace with a spine; 2) A1 and A2 peduncles bear a lower distal spine on article 1 and 3; and 3) the morphology and spinulation of P2 and P3.</p> <p>Their differentiation, nevertheless, posed no problems to Dworschak (1992) who studied materials from the Adriatic. The two can be separated by the length of the rostrum, the morphology and spinulation of the P1. They are more similar in western Mediterranean and a great overlap exists in the length/width ratio of the P1 propodus. In areas where both are present, e.g., in Banyuls, France (comparing Fig. 33 D-H with Fig. 37 C- G), the following characters can help set them apart: 1) the rostrum is over 1.5 times as long as wide at base with six to eight teeth on each lateral border in U. tipica (less than 1.5 times as long as wide with four or five teeth on each lateral border in U. pusilla); 2) P1 merus bears spines and spinules on two-thirds or the whole lower margin in U. tipica (with three to six spines and spinules on proximal half of the lower margin in U. pusilla); 3) P1 propodus bears a longitudinal upper row of two to four spines on mesial surface and an upper mesial subdistal and distal spine; there is no mesial distal spine near the cutting edge of dactylus, no longitudinal upper smooth crest on the lateral surface in U. tipica (with upper longitudinal tuberculate or spinous crest on mesial surface, upper mesial subdistal, distal spine and median distal spine near cuting edge of dactylus; upper lateral longitudinal smooth crest often present in U. pusilla); and 4) the telson is approximately quadrate, with the uropodal exopod longer than its distal width in U. tipica (telson is wider than long, with uropodal exopod about as long as its distal width in U. pusilla).</p> <p>It can be added that U. tipica prefers deeper water than U. pusilla (Picard 1965; Thessalou-Legaki &amp; Zenetos 1985; Dworschak 1992).</p> </div>	https://treatment.plazi.org/id/03FF2C63FFFEFFF82EDF7D5BFBE370FB	Public Domain	No known copyright restrictions apply.
