Merus with strongly projecting lobe on anterior margin. Carpus 2.5–3 times as long as wide, margins subparallel. Chela naked, fingers long, slender; gape with thick pubescence. Pereopods 2–4 smooth to granular; merus not inflated; all segments covered with scattered tufts of setae. Carapace length to 20 mm.
Color in life. Ground color chocolate brown, row of blue dots on median longitudinal ridge of palm of chela, red spot at base of dactyl of chela (Haig 1960)..
Habitat and depth. Among rocks and in piles of rocky rubble, lowest intertidal zone to at least 2 m.
Range. Baker Beach and Indian Beach, Humboldt County, California to Punta Eugenia, Baja California, Mexico. Type locality Morro Bay, California.
