Carapace excluding rostrum wider than long; dorsum smooth, densely setose on chelipeds and carapace, with transverse row of small epigastric spines; lateral margins divergent, spinose; anterolateral spine overreaching outer orbital spine; anterior branchial spine separated from remaining branchial spines by wide unarmed margin (occasionally with 1 or 2 small spines). Rostrum sharply triangular, margins unarmed or with few minute denticles. Sternite 3 anterior margin with deep, V-shaped median emargination. Basal antennal article with small outer spine; ultimate and penultimate articles each with distal spine. Antennal scale extending almost to or slightly overreaching apex of ultimate peduncle article. Ocular peduncle 1.4–1.5 × as long as wide. Crista dentata uniformly and minutely dentate. P2–4 similar; merus with small spines on extensor margin; propodus flexor margin broadened distally and lined with movable spines; dactylus flexor margin lined with strong, obliquely directed, corneous teeth.
