Diagnosis. Rostrum long, slender, reaching almost to end of antennular flagella, with 5–7 dorsal, 4–7 ventral teeth, dorsal half of rostrum without teeth. First, second segments of antennular peduncle with dorsal spine each, stylocerite nearly reaching end of first segment. Carapace with weak pterygostomian tooth. Pereopods lacking epipods. Pereopod 1 stout, chelate, other pereopods slender; pereopods 3–5 with long, slender dactyls bearing minute spinules, each merus of pereopods 3–5 with 4–6 spines. Pleura of abdominal somites 1–4 rounded, somite 5 with posterolateral point, somite 6 elongated; none with dorsal carinae. Telson with 5–6 pairs dorsolateral spines. Male total length 49 mm, female to 99 mm. Color in life. Mostly red with yellow background, white patches on first 3 abdominal pleura pereopods (Butler 1980, color plate 6C). Habitat and depth. Possibly semi-pelagic, usually lower continental slope, 90–2090 m. Range. Bering Sea to Oregon, Sea of Japan, Siberian coast.
