Diagnosis

This species is distinguished by the following characters: lateral process of premaxilla very low and wide; upper margin of the dentary almost flat distally, no distinct tubercle at the posterior end; posterior tip of the upper jaw reaching to or beyond a vertical through anterior margin of the pupil, sometimes reaching to the center of pupil; small teeth on endopterygoids, not forming obvious ridges; the anus is near or usually behind the posterior tip of the pelvic fin; lower gill rakers 18-24; midlateral scale count 40-44; lower margin of midlateral band reaching below ventral end of the midlateral (third) scale row and reaching to almost the center of the fourth scale row at level of the anal fin origin (Ref. 58474).
