Espinhos dorsais (total) : 10; Raios dorsais moles (total) : 12; Espinhos anais: 3; Raios anais moles: 7 - 8. Body pale brown dorsally with several vertical dark brown bars, becoming white ventrally; dorsal fin dusky with longitudinal yellow lines; pectoral, pelvic and anal fins dusky; caudal fin dusky with small yellow blotches (Ref. 13608). Preopercle has spines radiating from 2 centers (Ref. 26938).
