Alcock & Anderson, 1899
The carapace subquadrate and its side margins slightly convergent backwards; the dorsal surface is roughened under the lens, moderately convex from before backward and is sparingly granular toward the lateral margins. The front is extremely deflexed and divided into two rounded lobes, the eyestalks are roundish, the cornea without pigment.
Chelipeds are rather slender, longer than the first and fourth pairs of the ambulatory legs but shorer than the second and third pairs; the prehensile edges of both fingers of right chela are irregularly armed with sharp teeth; while in the left chela, the movable finger has irregularly toothed edge but the immovable finger is furnished with a row of brush of hairs in proximal half, having two (sometimes one) spines near the distal end, followed by two or three denticles; Merus of the ambulatory legs is naked; carpus, propodus, and dactylus are furnished with hair, the dactylus of the last pair is markedly recurved.
