Description
Size: Max length 8.0 cm CW (male)

Carapace somewhat discoidal in shape, owing to the curvature of the sides. There is only one short ridge on the carapace between the last transverse ridge anterior to it. The postero-lateral part of the carapace has a wrinkled appearance due to the presence of broad longitudinal ridges. Chelipeds in the male hardly longer than the carapace, shorter in the female. The first pair of ambulatory legs are very decidedly shortest and the 3rd pair the longest, the latter being about twice the length of the carapace. The 4th pair are longer than the first by a dactylus, and shorter than the 2nd by about two-thirds of a dactylus.
