Diagnosis. Rostrum slender, strongly ridged on sides, bent downward near base, reaching at most end of second segment of antennular peduncle, with 6–7 dorsal, 3 ventral teeth. First segment of antennular peduncle with closely set spinules on distal margin, second, third segments without spines or spinules, stylocerite not reaching end of first segment of peduncle. Flagella of first antenna subequal, longer than body. Flagella of second antenna also longer than body. Carapace with sharp antennal tooth, no branchiostegal tooth, pterygostomian tooth absent or minute. Third maxillipeds with exopod, epipod. Pereopods 1–4 with epipods. Pereopod 2 long, slender; carpus with 26–32 articles. Pereopods 3–5 with stout, spinose dactyls; merus of pereopod, 3, with 6–7 spines, pereopod 4, with 5–6 spines; pereopod 5, with 3 spines. Pleura of abdominal somites 1–4 rounded, of 5, 6, with points. Telson subacute, shorter than uropods, with 2 pairs dorsolateral spines. Total length to 75 mm.

Color in life. Banded with longitudinal red stripes, sometimes with green tinge. Cornea of eye reflecting golden color at night. The color notes are based on shrimp from Point Fermin, Los Angeles County, California.

Habitat and depth. Tide pools, kelp beds, rocky reefs, intertidal zone to 83 m. Adults can cling to drifting kelp and other objects at the surface of the sea.

Range. Usually south of Point Conception, California; rarely as far north as Tomales Bay; along coast of Baja California, Mexico south to Magdalena Bay, and in the northern Gulf of California to Guaymas. Type locality San Diego, California. Reports of this species from southern Mexico to the Galapagos Is. refer to other species of Lysmata , usually L. argentopunctata Wicksten, 2000 . Kuris et al. (2007: 651) stated that L. californica is "more common in central California and Oregon after El Niños", but there are no records of this species farther north than Tomales Bay.
