Dorsale stekels (totaal) : 12 - 14; Dorsale zachte stralen (totaal) : 3 - 4; Anale stekels: 14 - 15; Anale zachte stralen: 3 - 4. Head and body uniformly brown with a darker blotch on the gill cover. Forehead with a pale stripe. Dorsal and anal fins with orange tips. Distinguished from other rockfishes by its small size, undivided lower lateral line and the single pair of pores on the chin.
