Preopercular notch and knob poorly developed. Scale rows on back rising obliquely above lateral line. Color is red or reddish-orange, sometimes with an indistinct saddle-like black blotch on the caudal peduncle behind the dorsal fin. Median fins are reddish, sometimes with a yellow suffusion or narrow brown or black borders; pelvic fins are red; pectoral fins yellow.
Adults occur over rocky bottoms. They feed on fishes and crustaceans (Ref. 5213).
