. Carapace excluding rostrum wider than long; dorsum smooth, sparsely setose, with transverse row of strong epigastric spines in large specimens (in large specimens the epigastric spines are as large as adjacent branchial marginal 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 falling short of apex of ultimate peduncle article. Ocular peduncle 1.8–2.0 × 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.

Lateral margins broadly convex, divergent posteriorly, with row of distinct spines: first (anterolateral spine) well developed, directed straight forward, overreaching lateral orbital spine, followed by 2 small spines on hepatic margin; fourth spine situated on anterior end of anterior branchial margin, nearly as large as anterolateral spine, flanked by spine mesially (2 spines in largest specimen); 1 or 2 extra small spines between fourth and fifth; fifth strong, distantly posterior to preceding spine, situated on anterior end of posterior branchial margin, followed by 4–[6] posteriorly diminishing spines; last spine followed by low ridge along lateral margin. Rostrum elongate triangular, horizontal and directed straight forward; dorsal surface flattish basally, becoming rounded in cross-section distally; lateral margin straight, with up to 3 minute spines distally; length [1.8]–1.9 × width, [0.5]–0.6 × pcl, width about half (small specimens) or less than half (large specimens) carapace width at posterior carapace margin.
