The carapace of this new genus is a little broader than long, compared with that of Actaea, the proportion between length to breadth being 1 : 1.5, while that of Actaea 1 : 1.4. The dorsal surface is elegantly separated into areolae by deep grooves. Each areolae are covered sparingly with conical tubercles of various sizes. In the gastric area, 2M is longitudinally divided into two elongate lobules. The front is deeply bilobate, each one of which is margined with tubercles. The antero-lateral border is cut into five teeth, each of which is covered with tubercles and its top is larger and pointed.
Chelipeds are large and the wrist and palm are massive but not separated into lobules and are covered with conical tubercles of various sizes. (Sakai, 1983)
