Diagnosis

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 and gracile (body depth 25.3-30.6% SL); 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).

Coloration: base body coloration dark grey, paler ventrally; no well-defined pattern of bands or blotches on flanks; pelvic and anal fins often tinged pink; dorsal fin lappets often pink (females) or orange (males), tipped in black in both sexes; some individuals completely black in coloration; "tilapia spot" never present in soft dorsal fin (Ref. 81260).
