In the present material, we observed the occurrence of 7 plates in both males and females, and in few specimens had one of the posterior plates partially subdivided.

03B887D23E79FFC9FF2FE6B66C469CED.taxon	discussion	Remarks. It is an endemic species, known only from Brazil. Pachycheles greeleyi resembles P. chacei Haig, 1956 and P. serratus (Benedict, 1901) in the entire granulation on the chelipeds and dentition on the flexor margin of the cheliped carpus. However, P. greeleyi has more coarsely granulate carapace and more rugose and pubescent walking legs. Additionally, P. greeleyi has no gonopods in males, whereas P. chacei has one pair of gonopods in males and 5 telson plates. P. serratus presents a pubescent carapace and a pair of gonopods in males (Ferreira & Melo 2010).	en	Ferreira, Luciane Augusto De Azevedo, Melo, Gustavo Augusto Schmidt De (2016): Porcelain crabs from Brazil (Crustacea: Decapoda: Anomura: Porcellanidae).

03B887D23E79FFC8FF2FE31F6E9D9E28.taxon	discussion	Remarks. Ortmann (1892) originally described P. laevidactylus from Brazil. Later, Ortmann (1897) mentioned that the type-locality was not correct and synonymized the species with P. grossimanus (Guérin- Menéville, 1835) from the eastern Pacific. However, according to Harvey & De Santo (1996), specimens of the two species differ in some respects, and they should not be synonymized. Rodrigues da Costa (1960) described P. haigae Rodrigues da Costa, 1960 based on the material which had been identified by Moreira (1901) to P. rudis Stimpson, 1859. Harvey & De Santo (1996) concluded that P. laevidactylus was identical to P. ha i ga e, and both species were synonymized.	en	Ferreira, Luciane Augusto De Azevedo, Melo, Gustavo Augusto Schmidt De (2016): Porcelain crabs from Brazil (Crustacea: Decapoda: Anomura: Porcellanidae).

Considerable color variations have been reported for Petrolisthes galathinus by several authors (e. g., Benedict 1901; Rickner 1975; Abele & Kim 1989; Williams 1984). Werding (1977) was the first author to recognize the presence of different forms in the western Atlantic which were morphologically very similar but distinguishable by the detailed color pattern. These findings lead the author to describe P. rosariensis Werding, 1978, P. c ar i be n s i s Werding, 1983 and P. columbiensis Werding, 1983, and referred these species to the “ P. galathinus complex ”. Later, material of two additional color forms from the Caribbean coast of Colombia are described as P. sanmartini Werding & Hiller, 2002 and P. bolivarensis Werding & Kraus, 2002. Currently, the “ P. galathinus species complex ” consists of these six species which are morphologically distinguished by a combination of discrete differences, such as colour pattern, epibranchial spine, number of spines on the dactylus of walking legs and pubescence in the gape of cheliped fingers.	en	Ferreira, Luciane Augusto De Azevedo, Melo, Gustavo Augusto Schmidt De (2016): Porcelain crabs from Brazil (Crustacea: Decapoda: Anomura: Porcellanidae).

03B887D23E73FFC2FF2FE0CD684D982F.taxon	discussion	Remarks. Stimpson (1859) briefly described this species based on the single holotype from Barbados but no illustration of the species was given. The holotype was probably destroyed by the Great Chicago Fire (Evans 1967; Gore 1983). The identity of P. marginatus was reviewed by Gore (1983), who considered P. cessacii A. Milne-Edwards, 1878 from the Gulf of Mexico and Caribbean Sea, as a junior synonym of the former species. Material from the eastern Pacific identified to P. marginatus, belongs to P. haigae Chace, 1962, which is the sister-species of P. marginatus from the eastern Pacific. Chace (1962) noted that the two species may be differentiated by the number of the epibranchial spines: two in P. haigae instead of one in P. marginatus.	en	Ferreira, Luciane Augusto De Azevedo, Melo, Gustavo Augusto Schmidt De (2016): Porcelain crabs from Brazil (Crustacea: Decapoda: Anomura: Porcellanidae).

03B887D23E72FFC2FF2FE66E6F579C88.taxon	discussion	Remarks. Werding (1977) recognized the presence of different species similar to P. galathinus (Bosc, 1802) in the western Atlantic, and separated one specimen found in Santa Marta, Colombia. The single specimen was briefly described and illustrated as Petrolisthes sp I by Werding (1977). The epithet rosariensis was associated with the description and illustration of Petrolisthes sp I, from 1977, in his subsequent work (Werding 1978), but there was no description and illustrations. However, the initial description and illustration of Petrolisthes sp I by Werding (1977) was enough to recognize the species. Petrolisthes rosariensis is very similar to P. galathinus, but different from the latter mainly by the presence of two epibranchial spines (one epibranchial spine in P. galathinus) on lateral margins of the carapace; shape of the extensor margin of cheliped propodus (more convex on P. galathinus); and the lack of pubescence in the gape of the cheliped fingers (Werding 1982).	en	Ferreira, Luciane Augusto De Azevedo, Melo, Gustavo Augusto Schmidt De (2016): Porcelain crabs from Brazil (Crustacea: Decapoda: Anomura: Porcellanidae).
