Diagnosis. Rostrum narrowly triangular, not clearly carinate posteriorly, far overreaching middle of visible part of first segment of antennular peduncle. Ocular hoods armed with teeth. Second segment of antennular peduncle the longest, stylocerite almost reaching distal margin of first segment. Scaphocerite with blade reaching to middle of distal tooth, tooth overreaching distal end of antennular peduncle. Basicerite with sharp lateral tooth. Major chela of pereopod 1 with movable finger opening, closing in obliquely horizontal plane, finger with bulbous apex. Palm with superior, palmar, inferior grooves, strong tooth flanking base of dactyl, notches on superior and inferior margins. Merus of cheliped with 6–10 small spines on inferior margin, acute immovable tooth at distal end. Minor chela of pereopod 1 similar to major chela, but movable finger laterally compressed, forming lamellar expansion. Merus of minor pereopod 1 with 6–7 spines. Carpus of pereopod 2 with 5 articles, article 1 longest. Pereopod 3 slender, with simple dactyl, propodus with 7 movable spines, no tooth at end of merus, ischium with strong movable spine. Pereopods 4, 5 similar to third, but more slender. Telson with 2 pairs dorsal spines, posterior margin shallowly triangular, armed with pair spines on each lateral margin. Total length to 30.3 mm.

Color in life. Body ranging in color chestnut-brown to rich scarlet. Major chela mottled with yellow, tan; fingers with white apices. Minor chela orange. Posterior pereopods lightly banded with red, orange.

Habitat and depth. Among rocks, coralline algae or kelp holdfasts, low intertidal zone to 95 m.
