Maturity: Lm ?  range ? - ? cm
Max length : 100.0 cm TL male/unsexed; (Ref. 5222)
soft rays: 8. Distinguished by the following characteristics: dark red or brown head and body; darker pectoral fins than body; tips of interspinous dorsal fin membranes darker than the rest of the membranes; prominent black moustache streak occurs above maxilla; depth of body contained 2.4-2.6 times in SL; head length 2.3-2.4 times in SL; convex interorbital area; rounded preopercle, finely serrate, enlarged serrae at angle but covered by skin; distinctly convex upper edge of operculum (Ref. 89707).
Common in the Gulf of California. Occasionally encountered in isolated reefs and sandy bottoms near the coast at depths of 46 to 90 m; uncommon in shallow waters (Ref. 89707).
