Sakai, 1983
A small and dried specimen, none of its colouration has remained. The carapace is posteriorly broadened; the frontal and posterior borders are almost straight. The dorsal surface is covered with tiny granules, which are a little larger in anterior and frontal regions, very small and thicker in posterior and postero-lateral sides. The intestinal region is convex and thickly covered with tiny granules.
The chelipeds are very long, more than twice the length of carapace. (Sakai, 1983)
