Espinhos dorsais (total) : 11; Raios dorsais moles (total) : 20; Espinhos anais: 3; Raios anais moles: 17. This species is distinguished from its congeners by the following characters: less number of pored scales in the lateral line (27 vs. 37-46); longer snout (35.9% in HL vs. 28.2-35.5%); shorter first dorsal ray (12% in SL vs. 16.6-26.6%); longer caudal peduncle (8.5% in SL vs. 4.2-8.2%); shorter caudal fin (15.9% in SL vs. 19.8-25.9%); with a dark brown pelvic-fin spine (vs. white) (Ref. 116443).
Areas of collection vary from sheltered rocky outcroppings which are heavily covered by fine sediment to areas exposed to strong currents. Ambient seawater temperature varied between 19 and 21°C during dives conducted in April-May over several years. Azooxanthellate gorgonians, black corals, and solitary stony corals were the most abundant benthic invertebrates in this area (Ref. 116443).
