Description
Antennal flagellum completely excluded from orbital hiatus; posterior border of dorsum of carapace straight and forming a dog's eared angular junction with the postero-lateral borders; the posterior border of the arm ends in a spine. Last spine of antero-lateral border for larger than any of the others.

The length of carapace is not much more than half the extreme breadth measured between the tips of the last spine of the antero-lateral borders. Carapace covered with a dense short tomentum, convex, the regions well defined and fairly well areolated. The gastric region is divided into three sub-regions, the cardiac into two, and there is a very pronounced and independent swelling on the inner part of either branchial region. The antero-lateral borders are cut into six teeth of which the last is a Portunus like spine at least twice as long as those in front of it. The posterior border of the dorsum of the carapace forms a strong dogs eared angle of junction with postero-lateral borders. The front is cut into eight lobes arranged in four pairs, of which the outer most pair of teeth on either side are rather sharp. The chelipeds 2½ times the length of the carapace and all their surfaces are covered with granular transverse squamiform markings. The 6th tergum at the abdomen of the male is truncate triangular, having almost no curve to the sides. The anterior male abdominal appendages are extremely broad at the base. The tip is spoon-like and bears hairs along both borders.
