Body covered with short hairs and granules. Front composed of four teeth, the middle two being most prominent. Length of carapace distinct, more than half the greatest width. Carapace convex, covered with a coating of hairs concealing the granulated ridges, following ridges recognizable-curved mesogastric and epibranchial. Front cut into four lobes with squarish or rounded tips, inner frontal lobe a little smaller than outer. All frontal lobes project beyond the inner orbital lobe. Supra-orbital border with two distinct clefts.
Chelipeds sub-equal and short. Merus armed with three spines along the anterior border and unarmed along the posterior. Carpus with four distinct carinae all of which terminate in spines; inner and outer carinae reach up to the distal end of the segment, inner ending in the usual large spine of carpus; two carinae in the middle being short and not reaching the distal end of the segment; a short oblique carina confined to the distal half of the segment joining the dorsal hinge of carpus. Upper surface of propodus with three carinae of which inner two terminate in spines.
Inner and outer surfaces of propodus provided with a carina each.
Antero-external angle of merus of third maxilliped not produced laterally.
