There is no epipodite on the cheliped, and the sternal grooves of the female end side by side on the cheliped segment without actually meeting.

Carapace broader than long, smooth and hairy, the grooves between the regions almost wholly lost, a smooth, naked, oval boss on each side of the cardial region; the three teeth of the front of almost equal length and all sharp; teeth at the upper and lower inner, and at the outer orbital angles; two anterolateral teeth but no tooth at the branchial groove; a subhapatic tooth and a prominent angle of the mouth; the fingers of the chelipeds gaping and two blunt teeth on the wrist; a thorn at the end of the carpopodite in the first two pairs of walking legs, and another at the end of the propodite in the last two pairs, making with the end-joint a strong chela.

Borradaile described the carpus of P2 and P3 as being distally produced into a thorn. However, in the some material the distal part of the carpus of these legs are somewhat produced, but not thorn like.
