Diagnosis. Front of carapace slightly curved, depressed anteriorly. Stylocerite reaching almost to end of second segment of antennular peduncle. Scaphocerite broad, lateral tooth exceeding blade, reaching past middle of last segment of antennular peduncle. Anterior margin of carapace with 2 shallow sinuses. Pereopods 1 with fingers 0.5 times as long as palm, with or without gape. Pereopods 2 slender, with 5 carpal articles; article 1 equal in length to next 3 together. Pereopods 3, 4 slender, somewhat flattened, with thin, curved dactyls. Pereopod 5 similar to 3, 4 but with bands of setae forming brush on distal half of propodus. Pleura of abdominal somites 1–3 rounded, pleura of 4, 5 angled. Telson with 2 pairs spines on dorsal surface, 2 spines at each posteolateral angle, posterior margin deeply curved. Total length 35 mm.
Color in life. Color determined by distribution of blue and red chromatophores: translucent, reddish to purplish, pale green; turning blue at night (Hart 1964).
Habitat and depth. In pools, among oysters, in burrows of Upogebia pugettensis and Neotrypaea californiensis, intertidal zones.
