(Herbst, 1803)
As in Micippa thalia, the carapace is subquadrate and the hepatic regions very strongly depressed. No spines in the median line of carapace. The pseudorostrum is almost vertically deflexed in both sexes, it is divided into four laminar lobes, the median two are larger and directed downwards and separated by a V-shaped median sinus, while the lateral lobes are curved outwards at the tip.
The supraocular eaves have no spines. The intercalated spine is united with the postocular spine at the base. Behind the postocular spine follows a series of obtuse marginal spinules, of which there are sometimes as many as six, sometimes as few as three, and the one at the lateral angle of the branchial region is deviated to the dorsal surface. On the posterior margin, there are usually two very small teeth side by side. The basal segment of antenna is extremely broad, defining the tubular orbit anteriorly as well as ventrally; it has a terminal and a submedian tooth and its surface is smooth in basal half but covered with granules in distal half.
The first movable segment of antenna is flattened but not ovate in shape, its inner and outer borders being fringed with longish hairs. Chelipeds of male are stout, each segment being indistinctly granulated and the fingers widely gaping near the base; in the gemale, however, they are slender and smooth. On denudation, each segment of ambulatory legs is subcylindrical; carpus alone being somewhat depressed and longitudinally sulcated above. The merus has an indistinct distal spine on the upper border. (Sakai, 1938: 315)
