Petrolisthes dissimulatus Gore, 1983 (Fig. 41) Petrolisthes dissimulatus Gore 1983: 94, figs. 2–4; Poupin & Lemaitre 2014: 17, fig. 3E; Ferreira & Tavares 2017: 557; Poupin 2018: 149. Petrolisthes marginatus. — Benedict 1901: 134, pl. 3, fig. 1 [not Petrolisthes marginatus Stimpson, 1859]. Material examined . Panama [Caribbean]: 1 ov. female, cl 5.1, cw 4.9 (MZUSP 33525), Isla Grande, western point, depth 0.5–2 m, in crevices of coral rocks and dead corals, leg. A. Anker, J.F. Lazarus-Agudelo & T. Kaji, 27.03.2015. Previous records from Panama . None. Distribution . West Atlantic: Cuba, Puerto Rico, N, E and S Lesser Antilles, Panama (Isla Grande) and Colombia (Gore 1983; Poupin & Lemaitre 2014; present study). Ecology . Intertidal and shallow subtidal, known deptgh range: 0–2 m, probably deeper, to at least 15 m; on coral reefs and rocky habitats associated with reef, under coral rubble and in dead corals (Gore 1983; present study). Remarks . Petrolisthes dissimulatus is closely related to the amphi-Atlantic P. marginatus Stimpson, 1859, but can be distinguished from the latter by (1) the presence of two epibranchial teeth ( vs . a single epibranchial tooth in P. marginatus ); (2) the carapace subcircular, as wide as long ( vs . oblong, longer than wide P. marginatus ); (3) the front and median frontal lobe broader and less prominent than in P. marginatus (4) the P1 robust ( vs. P1 slender P. marginatus ); and (5) the P1 merus with two distal teeth on ventral side ( vs. single meral tooth in P. marginatus ) (Ferreira & Tavares 2017). It seems to be an uncommon species, sparsely recorded from a few Caribbean localities. The ovigerous female from Isla Grande (Fig. 41) apparently represents the first record from Panama. : Published as part of Ferreira, Luciane Augusto De Azevedo & Anker, Arthur, 2021, An annotated and illustrated checklist of the porcelain crabs of Panama (Decapoda: Anomura), pp. 1-154 in Zootaxa 5045 (1) on page 75, DOI: 10.11646/zootaxa.5045.1.1, http://zenodo.org/record/5532178 : {"references": ["Poupin, J. & Lemaitre, R.
