(H. Milne Edwards, 1853)

The dorsal surface of carapace much more uneven than in Chiromantes haematocheir and the antero-lateral borders sometimes marked with a rudimentary indentation behind the external orbital angle, although they are usually entire; the oblique rugae on the posterior lateral surface of carapace more strongly impressed; the gastric and cardiac regions are also more pronouncedly demarcated. The edge of the front is medially concave and the postfrontal ridge broken into four lobes. The outer surface of wrist and palm is thickly covered with granules, which are very often squamiform; the inner surface of palm also covered with depressed tubercles, a ridge of tubercles extends from the middle of its superior border toward the median portion. Carpus, propodus, and dactylus of ambulatory legs are very thickly fringed with long stiff hairs. (T. Sakai, 1939: 681)
