A NEW PORCELLANID SPECIES FROM THE CARIBBEAN SEA, WITH A DISCUSSION ON THE AMERICAN 'PETROL1STHES LEWSGROUP' (DECAPODA, ANOMURA, PORCELLANIDAE)

摘要

A new species of poicellanid crab, Petrolisthes hispaniolensis is described. This new species belongs to an American species assemblage, called here the P. few; si-group, so far represented in the Caribbean Sea by P. jugosus (Streets, 1872) and P. magdalenensis Werding, 1978 The new species is clearly distinguished from the other two western Atlantic species by the shape of the carpus of the chelipeds, which bears some irregular, spine-tipped proximal teeth The new species can also be distinguished by its coloration, as revealed by freshly collected specimens.
