Carapace strongly convex longitudinally and flattened transversely so as to be sub-cylindrical; regions ill-defined, with faint traces of gastro-cardiac, gastro-hepatic and branchio-hepatic sulci. Front deflexed, truncated. Eyestalk pyriform, thick in the middle, with a small pigmented cornea at distal ventral side. Antero-lateral border entire, 1.5 times as long as the postero-lateral, divergent; postero-lateral border only weakly convergent, provided with a fur on its narrow lateral wall. Chelipeds unequal; merus short, unarmed; carpus broader than long, sharply angulated at its inner angle; palm compressed and carinate for its upper margin; fingers also compressed, crenulate at inner margins. Ambulatory legs slender and hairy; dactylus of last leg distinctly curved backward and upward. (Takeda, 1989)
