Espinhos dorsais (total) : 15 - 16; Raios dorsais (total) : 8 - 10; Espinhos anais: 3; Raios anais : 4 - 6. Head spines very strong - nasal, preocular, supraocular, postocular, tympanic, parietal and nuchal spines present, coronal spines absent (Ref. 27437). Spiny ridge on sub-orbital bone; gill chamber mostly dark; third dorsal spine longest; slight notch on pectoral fin (Ref. 27437). Caudal fin slightly rounded (Ref. 6885). Red rockfish with some black on fins (Ref. 27437).
