Description
Chelipeds markedly unequal; No longitudinal groove on the propodus of cheliped; carapus and propodus of larger cheliped obtusely tuberculaterd, those of smaller chelipeds covered with sharp spines.

Carapace smooth except the deep cut areolation. Deep well-cut grooves separate the fronto-orbital region, define the gastric region, and subdivide the branchio-hepatic regions into 3 or 4 lobules. The gastric region is divided into 3 sub regions by fines but well cut lines. Front bilobed, the outer angle of each lobe being well defined and separated from the supra-orbital margin by a notch and grooves. Antero-lateral border cut into 4 teeth, of which the last two are procurved and spine like. Chelipeds markedly unequal, the larger one more than twice the length of the carapace. In the smaller cheliped, the upper and outer surfaces of the wrist and the upper and a large part of the outer surface of the hand are studded with sharp spine like tubercles. The upper edge of the meropodites of the legs is spiny, with a few long fine bristles. The dactylus is granular and bristly, and the lower edge also of the propodite has some bristles.
