Body medium, smooth. Urosome segment 2 not occluded dorsally. Rostrum short. Anterior head lobe truncated. Eyes large, subreniform. Antenna 1, anterodistal peduncular process strong. Upper lip, apical lobes slightly asymmetric. Lower lip regular, inner lobes weak, narrowly sloped. Mandible, spine-row short, with 6 pectinate blades; left lacinia 6 dentate, right lacinia blade-like. Maxilla 2, inner plate with 2 strong submarginal and subapical setae. Maxilliped, outer plate high, with one strong apical seta only and straight inner cutting edge; inner plate with 3 small inner spiniform setae and with 3 rows of 2–4 short stout plumose setae; palp segment 3 not produced distally, dactyl slender, slightly curved, not pectinated. Coxal plates 1–4 medium, little deeper than pereon, increasing posteriorly; hind corners of coxae 1–2 each with 3–5 small cusps. Pereopods 1 & 2 (gnathopods 1 & 2) medium, similar in form, carpus longer than ¾ length of propodus, palmar margin short, oblique, smoothly continuous with densely setose, elongate posterior margin. Pereopods 3 and 4 slender, medium long, dactylus medium in length. Pereopods 5–7 unequal in form; pereopod 5 the shortest; basis broadened, rounded behind, hind margin weakly serrate. Pleon plates 1–3, hind corners acuminate, not produced, posterior margins slightly sinuous. Uropod 3 slender, outer ramus not more than 2/3 the length of the inner ramus. Telson linguiform, apex subtruncate, paired notch and setae prominent; telson keeled proximally. Marsupial plates are leaf-like, broad, with short setae (Fig. 8b). Male is unknown. Distribution.
