Diagnosis:  Dorsal spines (total): 14-16; Dorsal soft rays (total): 10-12; Anal spines: 3-3; Anal soft rays: 8-9. Diagnosis: elongate and gracile, body depth 25.0-30.5% of standard length; mouth relatively small, upper jaw 26.8-28.8% of head length (Ref. 81260). Description: body elongate (Ref. 52307, 81260) and gracile (body depth 25.3-30.6% SL)(Ref. 81260). Snout long (34.0-39.0% HL); preorbital depth 20.0-25.2% HL; mouth relatively small, upper jaw short (26.8-28.8% HL); outer teeth in oral jaws with 2 unequal cusps or minor cusp reduced to a shoulder or absent; inner row teeth tricuspid at all sizes; lower pharyngeal jaw markedly longer than wide, teeth small and hooked; gill rakers small, conical; microbranchiospines usually present; lateral line system on head not markedly enlarged or inflated (Ref. 81260).
