DISCUSSION

The type material included only fragmentary chelipeds that preclude a detailed characterisation of the species. The only features that can be recognized are: propodus massive, very large and compressed with inner and outer surfaces strongly tuberculate, dorsal margin finely tuberculate, ventral margin strongly tuberculate with two rows of more or less aligned strong tubercles; dactylus and index triangular in cross section; dactylus with two lateral strong basal spines. We question the attribution of this material to Enoploclytia in view of the fact that diagnostic characters of this genus are found mainly on the cephalothorax. Moreover, the chelae of Enoploclytia usually have a globose propodus with very elongate fingers, as seen in specimens of E. collignoni . Only the discovery of more complete specimens can resolve the systematic position of these specimens.
