Stylocerite exceeding first segment of antennular peduncle. Third maxilliped, pereopods 1, 2 with epipods. Pereopods 3–5 slender, dactyls slender, weakly bifid. Merus of pereopod 3, with 2 spines; pereopod 4, with 2 spines; pereopod 5, with 1 spine. Pleura of abdominal somites 1–4 rounded, 5 with ventral point. Somite 3 with dorsal hump. Telson with 4 pairs dorsolateral spines. Female total length to 54 mm, male not reported.
Color in life. Not reported.
Habitat and depth. Benthic, 37–172 m.
Range. Sea of Japan, Sea of Okhotsk, Kuril Is. and Kamchatka; Bering Sea to Farallon Is., California. Type locality north of Bird I., Shumagins, Alaska. Word & Charwat (1976) included this species in their guide to the shrimps of southern California, but there are no records of this species south of the Farallon Is.
