87748C32F812F40FCE89FBE6FEA4F198.taxon	discussion	Remarks. Forty-five species are currently attributed to Calcinus, 35 of which are from the Indo-West Pacific, four from the eastern Pacific, three from the eastern Atlantic, and three from the western Atlantic (Poupin & Bouchard 2006; Malay et al. 2018). The specimens from TMV are assigned to Calcinus tibicen on the basis of the smooth upper margin of the right chela, whereas in the other two western Atlantic species, C. verrilli (Rathbun, 1901) and C. urabaensis Campos & Lemaitre, 1994, it is tuberculated or spinous. Additionally, in C. tibicen the posterior margin of the telson left lobe is provided with a single spine, whereas in C. verrilli and C. urabaensis it is armed with several spines. Calcinus tibicen and the eastern Atlantic C. talismani A. Milne-Edwards & Bouvier, 1892, superficially resemble each other in having the upper margin of the right chela smooth, and grooved P 3 propodus, but can be easily disguished in that the dorsal margin of the P 3 propodus is distinctly angulous in C. tibicen, whereas in C. talismani it is rounded (Poupin 2003). Mandai et al. (2018 a) considered the differences of color pattern among northeastern and southeastern Brazilian specimens of C. tibicen a case of polymorphism and, without further explanation, suggested that it “ might be related to the kind of nutrition as well different ecological and evolutionary predation characteristics. ” Later on, however, Mandai et al. (2018 b), based on two mitochondrial markers, found that northwestern Atlantic specimens differed from northeastern and southeastern Brazilian coast specimens, despite the lack of morphological evidences to support each genetic group. A number of sibling species in Calcinus can be split almost exclusively by color pattern (see for instance Poupin & Lemaitre 2003). Live coloration in C. tibicen can indeed vary dramatically, but color variants are found within the same population (Fig. 3) and in a limited geographical area and, hence, do not match the genetic groups of Mandai et al. (2018 b).	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

87748C32F81EF408CE89FC76FD44F623.taxon	discussion	Remarks. The specimens of Clibanarius from Trindade are herein provisionally assigned to C. tricolor (Gibbes, 1850). The specimens from Trindade share with C. tricolor s. str. the same pattern of transverse orange and blue bands on the articulations of P 2 and P 3. However, in C. aff. tricolor from Trindade the meri, carpi and propodi of P 2 and P 3 have whitish or pale blueish backgrounds (Fig. 4 A – C), instead of the bright blue backgrounds of the adults of C. tricolor s. str. (Fig. 4 E). In adults of both, C. tricolor s. str. and C. aff. tricolor from Trindade, the dark color on the chelae usually extends to the tips of the fingers (Fig. 4 B, E), whereas in juveniles the cheliped fingers are usually lighter than the palm (Fig. 4 D; Table 2). Juveniles of C. tricolor s. str. can have P 2 and P 3 with pale blueish backgrounds, cheliped palm dark, with whitish fingers (Fig. 4 D). In some species of Clibararius, such as C. virescens (Krauss, 1843), there are considerable intraspecific differences in color between specimens from different localities or even within the same local population (e. g. Morgan 1985; Yoshikawa et al. 2018). At this point, however, it is unclear whether the differences in size and color patterns between populations from northern localities and Trindade correspond with an intraspecific color variation of C. tricolor s. str. or with a yet undescribed species. Ongoing molecular and morphological studies of populations of C. tricolor s. l. from throughout its presumed distributional range are expected to add to our understanding of the boundaries between C. tricolor s. str. and C. aff. tricolor from Trindade. Clibanarius tricolor is morphologically closely related to C. antillensis Stimpson, 1859. Previous authors have found it difficult to separate between preserved specimens of C. tricolor and C. antillensis in which the color in life has faded away (e. g. Schmitt 1935; Provenzano 1959), and indeed we know of no realiable characters to date to distinguish between C. tricolor and C. antillensis other than the striking differences in color patterns. Specimens of C. tricolor and C. antillensis with color in life information can be easily distinguished from each other, for instance, by the presence of a transverse orange and blue bands on the articulations of P 2 and P 3, Fig. 4 A – C (vs. P 2 and P 3 pereopods with a broad, longitudinal, light stripe on a dark background at their lateral sides in C. antillensis, Fig. 4 F). Coelho (1965) recorded C. tricolor for the first time from south of the Caribbean Sea (Rocas Atoll, some 263 km off the coast of Brazil). A few years later, Forest & de Saint Laurent (1968) assigned 133 specimens collected by J. Forest in the oceanic island of Fernando de Noronha (FN) to Clibanarius tricolor (FN is located about 152 km east of the Rocas Atoll). Forest & de Saint Laurent (1968: 103) stressed that the specimens from FN are morphologically inseparable from C. chapini Schmitt, 1926 (known from the Cape Vert islands, and from Senegal to Angola coastal waters): “ Aucune différence morphologique ne sépare les formes est- et ouest-atlantiques [C. chapini and C. tricolor, respectively] et seule une différence de coloration, minime mais constante, nous interdit de les identifier ”. To the best of our knowledge, there are only a few, scattered references to the colors of the chelipeds and ambulatory legs for C. chapini (Schmitt 1926; Forest & de Saint Laurent 1968; Manning & Chace 1990), and our attempts to obtain color photographs of C. chapini failed. However, the brief color description by Forest & de Saint Laurent (1968: 99, key to Clibanarius species; 103, Table 2) for the FN material closely matches the color of the specimens from Trindade, but differs from C. tricolor s. str. (see above and also Table 2). Clibanarius rosewateri, a species being small in size (sl. ranging from 0.4 – 2.4 mm) so far endemic to Ascension Island, is also morphologically related to C. tricolor s. str. and C. chapini. However, C. rosewateri is unique in having a distinctive distal blue spot on the mesial and lateral surfaces of the propodus of P 2 and P 3, a character found neither in C. tricolor s. str. nor in C. chapini (viz. Manning & Chace 1990), or C. aff. tricolor from Trindade. It is worth noting that in the original description of C. rosewateri, Manning & Chace (1990) involuntarily also used three times the manuscript name Clibanarius ascensionis, which becomes a nomen nudum and hence is unavailable under the ICNZ (1999: Article 13). In the Table 1 we summarize the distinctive color characters between Clibanarius aff. tricolor from Trindade Island, C. tricolor s. str., C. chapini, and C. rosewateri. In addition to the oceanic island records, there are three records of C. tricolor from the Brazilian continental shores. Masunari et al. (1998) recorded C. tricolor for the first time from the coast of Paraná, based on a single specimen caught during a 1 - year survey at a rocky shore in Matinhos, with no further informations. Surprisingly, C. antillensis was not found during their survey, despite the species being long known from along the coast of Paraná. Nucci & Melo (2015) referred three males and three females (two ovigerous) from Camburí beach, Espírito Santo, southeastern Brazil (MZUSP 8867) to C. tricolor. These specimens were actually caught in April 1960 by Henrique Rodrigues da Costa (see Rodrigues da Costa 1964) and were in his collections before they went to MZUSP in 1987, with no color informations. However, Rodrigues’ da Costa (1964) report on his field trip to Espírito Santo in April 1960 should have given rise to caution as actually only two Clibanarius were recorded from Camburí, Tubarão Port: C. sclopetarius (Herbst, 1796) and C. antillensis. The third record of C. tricolor is an odd one from a Brazilian mangrove under strong influence of Amazonian waters in São Marcos Bay, Maranhão. This record was based upon a single specimen taken over muddy sediment with scattered vegetation (Sousa et al. 2015). We strongly suspect that the above records of C. tricolor (Masunari et al. 1998; Nucci & Melo 2015; Sousa et al. 2015) from the Brazilian shores actually refer to C. antillensis as, in absence of adequate color pattern informations, this species is easily mistaken for C. tricolor.	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

87748C32F819F417CE89F9A3FE0AF45F.taxon	discussion	Remarks. Seven species of Dardanus are currently known from the Atlantic: D. arrosor (Herbst 1796) (COS); D. calidus (Risso, 1827) (EA); D. fucosus Biffar & Provenzano, 1972 (WA); D. imperator (Miers, 1881) (ASC, STH); D. insignis (de Saussure, 1858) (WA); D. pectinatus (Ortmann, 1892) (EA); and D. venosus (H. Milne Edwards, 1848) (WA). The specimens from the oceanic island of Trindade are herein assigned to D. venosus. As already noted by Biffar & Provenzano (1972), D. venosus, D. fucosus and D. imperator closely resemble one another morphologically, and can be separated from their other Atlantic congeners in having the dorsal surface of the cheliped palm with tubercles surrounded by short setae, whereas in D. arrosor, D. insignis, and D. pectinatus it is provided with spinous transverse ridges or scutes. Dardanus venosus can be distinguished from D. fucosus in having no groove along the ventral margin of the left P 3 dactylus (vs. distinct groove present in D. fucosus). Asakura et al. (2003) suggested that the fleshy membranous protuberances on the female pleon (referred to as thin plates in Asakura & Hirayama 2002) are species-specific in Dardanus. Additional references in the literature to the fleshy membranous protuberances are very scarce and its function remains unknown (viz. Ayón-Parente & Hendrickx 2009). Females of D. venosus and D. fucosus do indeed possess two fleshy membranous protuberances (fmp) between both Pl 2 – Pl 3 and Pl 4 – Pl 5 (in one female of D. venosus examined herein the protuberances between Pl 2 – Pl 3 were lacking, and there was only one protuberance between Pl 4 – Pl 5, instead of two). Adult females of D. venosus and D. fucosus can be differentiated from each other in that the fmp between both Pl 2 – Pl 3 and Pl 4 – Pl 5 have rather entire margins in D. venosus (Fig. 6 A, B), whereas in D. fucosus the fmp are distinctly lobate (Fig. 6 C, D). In females of D. venosus and D. fucosus, the fmp between Pl 2 – Pl 3 are distinctly smaller than the protuberances between Pl 4 – Pl 5. In D. venosus, the male fmp, when present, resembles the female protuberance in having entire margins (Fig. 6 E, F). Males of D. venosus usually lack the fmp between Pl 2 – Pl 3 (all males from Trindade were devoid of protuberances, whilst a few males from the Brazilian continental shore had one small protuberance). The fmp between Pl 4 – Pl 5 is also absent in most males (only a few males from both Trindade and the continental shore had one fmp instead of none). The fleshy membranous protuberance formula does not support the separation of the population from Trindade into a different species from D. venosus. According to Biffar & Provenzano (1972), D. imperator can be distinguished from D. venosus and D. fucosus in having more prominent grooves and ridges on the P 3 propodus. However, the development of the propodal grooves and ridges is actually highly variable. Manning & Chace (1990: 40) reported that the cross ridges on the left P 3 propodus are distinctly concave in D. imperator, conversely to the holotype of D. imperator illustrated by Biffar & Provenzano (1972: fig. 4 C) in which the propodal cross ridges seem to be convex in cross section. In the male and female of D. imperator (MZUSP 37955) from St. Helena the cross ridges are only slightly concave (Fig. 6 E). In D. venosus from Trindade the cross ridges on the propodus of the left P 3 are consistently deeply concave, whilst in a large series of males and females from the Brazilian coast the cross ridges vary in the degree of concavity both below and above the longitudinal middle ridge (Fig. 6 B – D). Similarly, the development of the propodal grooves and cross ridges are variable between the female and male from Bermuda and Belize, respectively (Manning & Chace, 1990: fig. 21 A, B). Therefore, the effectiveness of the propodal grooves and ridges for distinguishing between D. venosus and D. imperator remains unsettled and deserves further investigation. Despite the paucity of morphological characters to reliably diagnose D. venosus and D. imperator, these two species display distinct color patterns. In the original description of D. venosus, H. Milne Edwards (1848) described D. venosus as being “ ... yellowish, stained with red, which on the fingers and inner surfaces of the palms form a reticulated pattern of thin lines, so as to resemble capillary veins ” [the species name, venosus, allude to this feature]. H. Milne Edwards (1848) also referred to the presence of “ redish, stiff setae on the ambulatory legs ”. Although the color pattern can vary from pale red to blood red in D. venosus (Fig. 7 A – F), the striking reticulated pattern of reddish lines (venation) which covers almost completely all surfaces of the shield, chelipeds and pereopods allows for its straightforward recognition. On the other hand, D. imperator can be promptly differentiated from D. venosus in possessing a distinctive deep purple shield, purple-banded ocular peduncles, chelipeds and ambulatory legs, and by a faint reticulated reddish pattern on the ventral faces of ambulatory legs, and inner surfaces of the cheliped carpus and palm extending onto fingers (Fig. 8 A – D). Manning & Chace (1990) provided a detailed description of the color in life of D. imperator.	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

87748C32F800F413CE89FBB4FB55F197.taxon	discussion	Remarks. The specimens from Abrolhos and Trindade and Martin Vaz (Fig. 9 A – F) are herein attributed to I. margaritensis on the account of the cheliped palm with 1 or 2 rows of short spines on the middorsal line and dorsomesial and dorsolateral margins, ambulatory leg dactyli with 2 – 5 corneous spines on the ventromesial face, anterior lobes of the P 3 sternite subsemicircular, and P 4 and P 5 sternites with stiff setae (in males and large females) (García-Gómez 1983). However, the Brazilian specimens differ from those from northern localities in having the ocular peduncles approximately half the length of the shield (Fig. 9 A) (vs. ocular peduncle approximately two-thirds to three-fourths of the length of the shield in the northern specimens), and in having a row of small spines proximally on the right cheliped dactylus dorsal surface (Fig. 9 C) (vs. row of small spines lacking in the representatives from northern localities). In the absence of more specimens from Brazil, we tentatively interpreted the differences between the southern and northern specimens as variations only and, therefore, assigned the specimens from Abrolhos and TMV to I. margaritensis. Iridopagurus margaritensis was previously known from the Caribbean Sea and north coast of South America (off French Guiana). The present record from TMV and Abrolhos are the first from Brazilian waters, thus extending considerably the range of this species by many thousands of km to the south, from 6 ° N to 20 ° S.	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

87748C32F802F418CE89FD28FED7F1BB.taxon	discussion	Remarks. The American genus Iridopagurus comprises nine species, seven of which are Atlantic in distribution: I. caribbensis (A. Milne-Edwards & Bouvier, 1893), I. dispar (Stimpson, 1859), I. iris (A. Milne-Edwards, 1880), I. globulus de Saint Laurent-Dechancé, 1966; I. margaritensis García-Gómez, 1983, I. reticulatus García- Gómez, 1983, and I. violaceus de Saint Laurent-Dechancé, 1966. Within the Atlantic American Iridopagurus, the closest morphological affinity of I. martinvaz sp. nov. is with I. reticulatus, to which it superficially resembles in having the anterior lobe of the sternite of P 3 roundly rectangular (Fig. 10 C) (see also García-Gómez 1983: fig. 3 H). However, I. martinvaz sp. nov. can be separated from I. reticulatus in having 1) the dorsal surface of the right cheliped with 1 median row of small spines and sub-median irregular rows of spinules, Fig. 11 A (vs. dorsal surface of right cheliped with few irregular rows of short spines); 2) chelipeds pearly white with the lateral surface of the fixed fingers and dorsal surface of the propodi with a red-orange patch proximally, and carpus ringed with a deep red, transversal, narrow band subdistally, Fig. 14 A (vs. dorsal surfaces of palms and carpi reticulated with brown in I. reticulatus, Fig. 14 B); 3) ocular peduncles whitish dorsally, ringed with deep red distally and dull orange subproximally, Fig. 13 A – D (vs. ocular peduncles brown dorsally, ringed with dull orange only subproximally in I. reticulatus, Fig. 14 B); 4) telson with posterior lobes separated by shallow, Ushaped, median cleft, Fig. 10 D (vs. deep median cleft in I. reticulatus, see García-Gómez 1983). Iridopagurus reticulatus does occur in the Brazilian coast. Coelho et al. (1983) first recorded it as I. dispar, based on a single specimen from Porto de Pedras, Alagoas (~ 09 ° S). Later, that specimen was re-identified by Coelho et al. (1990) as I. reticulatus. Nucci & Melo (2011) accepted the identification of the specimen from Alagoas (MOUFPE 3671; ex-DOUFPE 3671) with I. reticulatus. This, however, cannot be confirmed by us as that specimen no longer exists in the collections of the MOUFPE (J. Fidelis, pers. com.). Nucci & Melo (2011) extended the distribution of I. reticulatus further south based on the female MZUSP 13877 from Santa Catarina (~ 27 ° S). However, the present re-examination of the specimen MZUSP 13877 revealed that it could not be attributed to Iridopagurus as it lacks the diagnostic quadriserial gills of the genus (the specimen from Santa Catarina has biserial gills instead) and has an accessory tooth near to the crista dentata (species of Iridopagurus have no accessory teeth near the crista dentata). No generic assignment for the female MZUSP 13877 has been attempted at this point because it has no paired first pleopods modified into gonopods and its right cheliped and P 4 have been lost. In the MZUSP collections there is one male from Maranhão (~ 02 ° S) (MZUSP 36517), which we tentatively identify with I. reticulatus. Hence, from the available evidence, along the Brazilian coast I. reticulatus is only known from Maranhão and Alagoas. Iridopagurus martinvaz sp. nov. differs from I. dispar and I. iris in having the chelipeds moderately spinose and the left cheliped merus distodorsal margin without spines, respectively (vs. chelipeds smooth in I. dispar, and left cheliped merus with a strong spine on the distodorsal margin in I. iris). The new species can be split from I. globulus in that the right cheliped palm is distinctly spinose on the dorsolateral margin, and by the lack of a bundle of fine setae at the base of the corneous claw of P 4, whereas in I. globulus the right cheliped palm dorsolateral margin is inermis, and the base of the P 4 corneous claw is provided with a distinct bundle of fine setae — referred to as “ preungual process type I ” by García-Gómez 1983). Iridopagurus martinvaz sp. nov. can be easily distinguished from I. caribbensis in having the anterior lobe of the sternite of P 3 roundly rectangular, Fig. 10 C (whereas in I. caribbensis it is subsemicircular) and in that the antennal acicle falls much short of the distal margin of the cornea, Fig. 10 A (whereas in I. caribbensis it extends far beyond the distal margin of the cornea). It differs from I. margaritensis and I. violaceus in having the P 3 sternite anterior lobe roundly rectangular (Fig. 10 C), and the P 4 and P 5 sternites each with a transversal row of simple setae, respectively, Fig. 10 C (vs. P 3 sternite anterior lobe subsemicircular in I. margaritensis, and P 4 and P 5 sternites each with a transversal row of stiff setae in I. violaceus).	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

87748C32F80AF421CE89FD09FDD6F29B.taxon	discussion	Remarks. Nematopagurus was erected by A. Milne-Edwards & Bouvier (1892) for a single eastern Atlantic species, N. longicornis A. Milne-Edwards & Bouvier, 1892, currently known from Ireland to Angola, and the Mediterranean Sea (McLaughlin 2004). No other species in the genus is known from the Atlantic Ocean to date, while 25 additional species have been reported from the Pacific Ocean, as far east as Hawaii and French Polynesia. Nematopagurus micheleae sp. nov. is hence the second Atlantic species of Nematopagurus, and the first representative of the genus from the western Atlantic. The new species is confidently assigned to Nematopagurus (sensu McLaughlin, 2004) on the account of its long, distally filamentous male right sexual tube, directed from the right to the left across the ventral body surface, and very short left sexual tube, readily recognized in the holotype and paratype males. Nematopagurus micheleae sp. nov. can be immediatelly separated from all its congeners in having the terminal margin of the posterior lobe of the telson inermis (Fig. 14 E), whereas in all other Nematopagurus the terminal margins of the telson is distinctly spinose. The new species can be further differentiated from the eastern Atlantic N. longicornis in having (1) the ocular peduncle swollen basally, tapering distally to a reduced cornea, Fig. 15 A (vs. ocular peduncle broadening distally to a dilated cornea in N. longicornis); (2) the P 2 and P 3 dactili ventral margins each with 5 – 8 corneous spines, Fig. 18 A – C (vs. P 2 and P 3 dactli ventral margins each with 12 – 18 corneous spines); and (3) the length of the P 3 dactylus 6.4 its height, Fig. 18 B (vs. length of the P 3 dactylus 13.4 its height in N. longicornis). Nematopagurus sp. nov. and N. helleri (Balss, 1916) from the Red Sea are superficially similar to each other in that their ocular peduncle is swollen basally, tapering distally to a reduced cornea, but can be further separated by the P 2 and P 3 carpi dorsal surface inermis, Fig. 18 A – C (vs. P 2 and P 3 carpi each with a dorsodistal spine. Additionally, P 2 carpus with 2 – 4 widely-spaced spines on its dorsal surface and P 3 carpus usually with 1 – 2 spines on its proximal third in N. helleri) (see McLauglin 2004: 187, 188, fig. 13 C). Differently from the remaining Nematopagurus species, known from waters between 100 – 2600 m, the new species is a shallow-water one (15 m).	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

87748C32F830F422CE89FD7DFC78F0FF.taxon	discussion	Remarks. For many years there have been evidences for the existence of cryptic species in P. brevidactylus, including differences in color pattern (Lemaitre et al. 1982; Lemaitre & Tavares 2015). Pagurus brevidactylus is widely distributed in the western Atlantic shores from Bermuda (~ 32 ° N) to Santa Catarina, Brazil (~ 27 ° S), but is also known from the oceanic islands of Fernando de Noronha (Nucci & Melo 2007) and Trindade (this report). The color pattern in life for P. brevidactylus (Stimpson, 1859) s. str. was described in detail by McLaughlin (1975) based on the male neotype, sl 2.1 mm, obtained from the type locality, Barbados (~ 13 ° N). The population from Trindade (~ 20 ° S) diverge in color pattern from the specimens from northern localities (for instance Barbados, aff. MacLaughlin 1975; Saint Martin, Fig. 19 F), but in the absence of additional evidence it is herein, only tentatively, attributed to P. brevidactylus (Stimpson, 1859). Pagurus aff. brevidactylus differs in color pattern from P. brevidactylus s. str. (cf. McLaughlin 1975) in having (1) ocular peduncles distinctly bicolor, with a pale brown transverse band proximally and a dark blue to black distal band, Fig. 19 A – E (vs. “ ocular peduncles mottled light pink with brownish and greenish-black stripes ” throughout the length of the peduncle in P. brevidactylus, Fig. 19 F); (2) antennular peduncles distinctly blue, Fig. 19 A, C (vs. antennular peduncles “ greenish or brownish-black ” in P. brevidactylus, Fig. 19 F); (3) ambulatory legs whitish, occassionally with slender, longitudinal pale orange stripes; dactyli and propodi each with one proximal, transverse dark band each; carpus and merus with one median, transverse dark band each, Fig. 19 A – D (vs. ambulatory legs “ white with dorsal, lateral, mesial and ventral longitudinal [distinct] stripes of greenish or brownish black and darker broad transverse band medially on each segment, lateral faces also with median longitudinal stripe of red or reddish-brown, occasionally greenish-brown ” in P. brevidactylus, Fig. 19 F).	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

87748C32F833F435CE89FBB0FA16F53F.taxon	discussion	Remarks. Pagurus carmineus sp. nov. is morphologically closely related to the “ provenzanoi group ” of species with multispinose ocular acicles, especially P. brevidactylus. However, P. carmineus sp. nov. can be readly differentiated from P. brevidactylus in having the propodal rasp consisting of 2 – 3 rows of ovate corneus scales (Fig. 24 F), whereas the propodal rasp has 4 – 6 rows of ovate corneus scales in P. brevidactylus. The new species can be further distinguished by the ratio length / width of the ocular peduncles, markedly short and stout, about twice as long than wide in P. carmineus sp. nov. (Fig. 21 A), whereas the ocular peduncles are distinctly longer and slender, about four times as long than wide, in P. brevidactylus. True, the use of the ratio length / width of the ocular peduncles as a distinguishing character between species of paguroids should be used cautiously, as the ratio length / width varies over ontogeny and juveniles tend to have short- er and stouter ocular peduncles than adults. And in some species, the females can become ovigerous before attaining the ratio length / width of full-sized adults, e. g. Clibanarius tricolor (see Provenzano 1960). However, in some species of micro-pagurids recently discovered the adults had stout eyes and diminutive size (Lemaitre et al. 2017). This is also the case of P. carmineus sp. nov., of which we have examined 42 males (largest sl 1.2 mm, smallest sl 0.4 mm) 15 females (largest sl 1.0 mm, smallest sl 0.7 mm) and 15 ovigerous females (largest sl 1.2 mm, smallest sl 0.7 mm). Commonly, largest juveniles and smallest adults of decapod crustaceans overlap over a size range at their transition (DeMartini et al. 2005; González-Pisani et al. 2017). In P. carmineus sp. nov. it seems that the shield length of the largest juvenile female and smallest adult female overlap between 0.7 mm and 1.0 mm; overlapping and full grown females (> 1.0 mm sl) do not vary in terms of ratio length / width of the ocular peduncles. Pagurus carmineus sp. nov. is distinctly smaller (sl minimum – maximum = 0.7 – 1.2 mm; sl mean ± SD = 0.9 ± 0.1 mm; N = 53 spec) than its congeners of the “ provenzanoi group ” of species with multispinose ocular acicles, such as P. brevidactylus (sl minimum – maximum = 1.0 – 4.0 mm; sl mean ± SD = 2.0 ± 0.4 mm; N = 195 spec) (Lima et al. 2014). The new species is striking for carrying few, large eggs (minimum – maximum eggs / spec = 2 – 22; eggs / spec mean ± SD = 10.4 ± 6.5; egg minimum – maximum major diameter = 0.3 – 0.5 mm; egg major diameter mean ± SD = 0.40 ± 0.05 mm, Fig. 21 A, B). Conversely, P. brevidactylus carry many small eggs (minimum – maximum eggs / spec = 27 – 1075 eggs; eggs / spec mean ± SD = 158 ± 119; egg major diameter mean ± SD = 0.38 ± 0.04 mm) (Iossi et al. 2005). Komai & Osawa (2001: 1295, fig. 3 H) reported that Pagurus decimbranchiae Komai & Osawa, 2001, had only one arthrobranch on the third maxilliped greatly reduced to a single rudimentary bud, in lieu of having a pair of well developed biserial arthrobranchs. Komai & Osawa (2001) assigned P. decimbranchiae to the Pagurus anachoretus Risso, 1827, species group with which P. decimbranchiae share a number of morphological characters. Hitherto, no other species of Pagurus is known to have a rudimentary bud on the third maxilliped. The finding herein that P. carmineus sp. nov. also have only one arthrobranch on the third maxilliped reduced to a non-lamelate bud (Figs. 20 C, D, 22 A) prompted us to investigate the gill formula of other species of the “ provenzanoi group ” from the southwestern Atlantic (SWA). As a result, we have found that the arthrobranch on the third maxilliped is also reduced to a single bud in P. aff. brevidactylus from Trindade (Fig. 20 A, B), P. brevidactylus s. str., P. criniticornis, P. leptonyx Forest & de Saint Laurent, 1968, and P. provenzanoi. A fifth species of the “ provenzanoi group ” also known from the SWA, P. trichocerus Forest & de Saint Laurent, 1968, only known from the male holotype and most probably a synonym of P. leptonyx, has not been examined. The “ provenzanoi group ” is amphi-American in distribution and consists of 26 species (12 western Atlantic and 14 eastern Pacific species). Recent molecular analyses based only on a few species suggested the monophyly of the “ provenzanoi group ” (Olguín & Mantelatto 2013; Noever & Glenner 2017). Although many more species from the “ provenzanoi group ” await investigation, whether by molecular or morphological techniques, the reduction of the arthrobranch on the third maxilliped to a single bud may be a promising synapomorphy defining morphologically this species group.	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

87748C32F824F437CE89F970FDAEF230.taxon	discussion	Remarks. Among the “ provenzanoi group ” of species from the western Atlantic, Pagurus provenzanoi share the presence of multispinose ocular acicles with P. brevidactylus, P. carolinensis, P. leptonyx, P. trichocerus. However, P. provenzanoi can be separated from P. leptonyx and P. trichocerus by the presence of short setae on antennal flagellum, whilst the latter species have long setae on the antennal flagellum. Pagurus provenzanoi is morphologically closely related to P. brevidactylus and it is not uncommon that the two species are confused with each other. Lemaitre & Tavares (2015), for instance, reported one ovigerous female of P. brevidactylus [MZUSP 36506, not MZUSP 16832 as reported by Lemaitre & Tavares (2015)] from the Vitória-Trindade Seamounts Chain. However, reexamination herein of that specimen revealed that it actually belongs to P. provenzanoi. The two species can be best differentiated by the presence of dense, short mat-like setae on the dorsal surface of the cheliped propodi in P. provenzanoi, vs. dorsal surface of propodi with scattered, long stiff setae in P. brevidactylus. Pagurus provenzanoi is herein recorded for the first time from the Vitória-Trindade Seamount Chain (Jaseur, Davis and Dogaressa seamounts and from Trindade Island (Fig. 1 A – C). Nucci & Melo (2007) have recorded P. provenzanoi from as south as Santa Catarina (~ 27 ° S) based on a male from Porto Belo (MZUSP 13808). Reexamination of that specimen revealed that it actually belongs to P. brevidactylus (Lima & Santana, unpublished).	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

87748C32F826F437CE89FDEEFBD4F4AF.taxon	discussion	Remarks. Phimochirus holthuisi is closely related to P. operculatus (Stimpson, 1859), also from the western Atlantic. However, whereas in P. holthuisi the middorsal surface of the minor cheliped palm is elevated, unarmed or provided with only a few, small spinules or tubercles proximally, in P. operculatus it is provided with a row of small spines or spinules extending to the distal margin next to the dactyl. Phimochirus holthuisi further differs from P. operculatus in that the ventral margin of the minor cheliped merus is armed with one strong spine and a few smaller spines or spinules, instead of a row of strong spines as in P. operculatus (McLaughlin 1981 b). As noted by McLaughlin (1981 b), in Phimochirus the more taxonomically helpful characters are found on the left cheliped. As already pointed out by McLaughlin (1981 b) for northern specimens, the moderate to large specimens from the Vitória-Trindade Seamounts Chain tend to have larger tubercles on the dorsal surface of the major cheliped fixed finger and palm distally, whilst smaller specimens superficially resemble P. operculatus in having granular or weakly tuberculate fixed finger and palm dorsodistally. Phimochirus holthuisi mainly occurs in depths exceeding 30 m down to 210 m, in shell, sand, mud and coral bottoms (McLaughlin 1981 b; Williams 1984). In the Vitória-Trindade Seamounts Chain (Montague, Davis and Dogaressa, this report) it occurred in sandy coral rubble sable between 60 and 81 m.	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.

The specimen here reported from Trindade Island is assigned to Phimochirus, whose diagnostic characters (McLaughlin 1981 b) are readilly reconized in the Brazilian material, namely, 11 pairs of biserial gills, crista dentata of the third maxilliped with one accessory tooth, propodal rasp with one row of corneous scales (Fig. 26 F), presence of a well-developed preungual process (Fig. 26 F), and females with first pleopod paired and modified as gonopods. Phimochirus leurocarpus superficially resembles P. occlusus (Henderson, 1888), from which it can be readly distinguished by the presence of a row of spines on the ventral margins of dactyls of the ambulatory legs (Fig. 26 B – D), such spines are absent in P. occlusus. This is the first record of P. leurocarpus from the southwestern Atlantic (Brazil), hence extending its distribution southward to around 20 ° S. The species was previously known only from the type material from Straits of Florida and Venezuela, and a few additional specimens from Bermuda and Puerto Rico. Here, we also recorded a specimen from Curaçao.	en	Lima, Daniel, Tavares, Marcos, Jr, Joel Braga De Mendonça (2019): Paguroids (Decapoda: Anomura: Diogenidae and Paguridae) of the remote oceanic Archipelago Trindade and Martin Vaz, off southeast Brazil, with new records, description of three new species and zoogeographical notes.
