This species is distinguished from its congeners by the following set of characters: D XI,I+21-22; A II,23-24; lateral line with 65-76 scales, 4-5 scale rows between the dorsal-fin origin and the lateral line; gill rakers with 3+7-8 on the first gill arch; vertebral formula with 14 or 15 abdominal vertebrae (predominantly 14), 4-5 predorsal vertebrae (mostly 4), and 14-15 caudal vertebrae (mostly 14), resulting in a total vertebral count of 32-34 (mostly 32); dark blotches or a mid-lateral stripe absent; swim bladder features two posterior extensions, with a duct-like process originating from the anterior end of the swim bladder and beginning at the junction of the roots of the two posterior extensions; and five wide extensions connect the posterior sub-extensions of the anterolateral extensions to the body of the swim bladder (Ref. 138100).
