Petrolisthes hispaniolensis Werding & Hiller, 2005 View in CoL

( Fig. 4A View FIG )

Petrolisthes hispaniolensis Werding & Hiller, 2005 View in CoL : figs 1, 2 a-i (type locality: Dominican Republic).

MATERIAL EXAMINED. — Guadeloupe. KARUBENTHOS, 2012, 2 ♂♂ 3.3 × 3.2 mm, 3.0 × 2.9 m ; 1 ♀ 3.4 × 3.5 mm. MNHN-IU-2013-7156, st. GM22, lot JL1012.

DIAGNOSIS. — Carapace with few transverse striae on gastric and branchial regions; protogastric ridge elevated; supra-ocular and external orbital angles unarmed; epibranchial region swollen, unarmed. Carpus of cheliped with three or four, inconspicuous, irregular teeth in proximal half of anterior margin, anterodistal angle rounded; posterior margin evenly curved; dorsal surface with oblique rows of granules forming longitudinal crests. Dorsal surface of palm finely granular, with longitudinal shallow groove along anterior margin, extending onto fixed finger; anterior margin unarmed, minutely serrated; posterior margin unarmed; gape of fingers with pubescence. Ambulatory legs unarmed on anterior margins; dactylus with four movable spines on posterior margin. Telson composed of seven plates.

REMARKS. — This is the first record of P. hispaniolensis from the Lesser Antilles.

Overall, the morphological characters of the present three specimens agree well with those of P. hispaniolensis as described by Werding & Hiller (2005). Live color is also similar, especially in having “a broad, longitudinal, whitish stripe from the front region to the posterior margin of carapace” (cf. Werding & Hiller 2005: 1187, http://www.uni-giessen.de/ porcellanidae /). Petrolisthes hispaniolensis belongs to the “ P. lewisi ” group represented in the western Atlantic by two others species, P. jugosus Streets, 1872 and P. magdalenensis Werding, 1978 ( Werding & Hiller, 2005). It is closer to P. magdalenensis but can be separated by the morphology of the carpus of the chelipeds and live coloration, as documented by Werding & Hiller (2005: 1189).

HABITAT. — A small species, collected in the intertidal region at low tide, on coral rubble.

DISTRIBUTION. — Western Atlantic: Dominican Republic and Lesser Antilles (ICA, Guadeloupe).

Pisosoma jugosum View in CoL – Haig 1956: 16 ( Tobago, Cubagua, La Tortuga, Curaçao).

MATERIAL EXAMINED. — Guadeloupe. KARUBENTHOS, 2012, 1 juv. 1.7 × 1.7 mm, MNHN-IU-2013-5428, st. GM07, lot JL389 ; 1 ♀ 3.8 × 4.1 mm, MNHN- IU-2013-5292, st. GM08, lot JL401; 1 ♂ 3.0 × 2.8 mm, MNHN-IU-2013-5291, st. GM17, lot JL792b.

REMARKS. — The diagnostic characters of this species are almost the same as those for P. hispaniolensis , except for the following characters present in P. jugosus : carpus of cheliped with four large serrated teeth on anterior margin (distalmost tooth smallest), anterodistal angle squared; gape of fingers of cheliped glabrous; telson composed of five plates.

This is the first record of P.jugosus from Guadeloupe Island. Petrolisthes jugosus belongs to the “ P.lewisi group” characterized by the possession of longitudinal crests on the dorsal surface of the carpus of the chelipeds. In complement of the morphological characters mentioned herein, P. jugosus can be separated from P. hispaniolensis , a species also of the “ P. lewisi group”, and collected at Guadeloupe, by the carmine red coloration of the chelipeds and carapace, and no whitish stripe on the front to posterior margin of the carapace (compare Figs 4A, B View FIG ).

HABITAT. — Collected in the lower intertidal region at low tide under rocks and coral rubble.

DISTRIBUTION. — Western Atlantic: from Florida Keys, USA, Greater Antilles, Virgin Islands and Lesser Antilles (ICA, St Martin, Guadeloupe, Barbados, Tobago; IOV, Cubagua, Margarita, La Blanquilla, La Tortuga, Bonaire, Curaçao), Mexico, Panama, Colombia, to Venezuela.
