Diagnosis. Rostrum long, arched over eye, with 13–18 dorsal teeth, 2 or 3 spines, 9–15 ventral teeth. Eye large, pigmented. Carapace with strong antennal, moderate pterygostomian teeth. Antennular peduncle short, stylocerite short, flat; outer flagellum longer than body. Scaphocerite much longer than antennular peduncle, blade longer than lateral tooth; length of antennal flagellum 1.5 times as long as body length. Third maxilliped with antepenultimate segment with broad lamella, distal 2 segments slender, epipod present. Pereopods 1–4 with epipods. Pereopod 1 shorter than third maxilliped, ischium with broad lamella, dactyl with rounded apex. Pereopod 2 long, slender, with 26–33 carpal articles, chelate. Pereopods 3–5 slender, with simple dactyls; pereopod 3 with 0–1 spine on ischium, 7–9 outer, 3–5 inner meral spines; 2–3 carpal spines; pereopod 4 with 0-1 spine on ischium, 8–9 outer, 1-3 inner meral spines; 1–3 carpal spines; pereopod 5 without spine on ischium, 8–9 outer, 1–3 inner meral spines; 1–3 carpal spines. Posterior margin of abdominal somite 3 projecting over somite 4, pleura of somites 1–3 rounded, 4–5 with distolateral points, small spinule at midlateral posterior border of somites 4–5, somite 6 with posterolateral point. Telson narrow, 5–7 pairs dorsolateral spines, apex acute. Outer uropod longer than telson. Male total length 182 mm, female 208 mm.
