This species is distinguished from its congeners by the following set of characters: rigid upper jaw with no flexible lamina posteriorly, extending 0.6 to 0.9 eye diameters behind posterior margin of orbit; infraorbitals moderately slender except 2nd and 3rd infraorbitals much larger with large sensory canal openings, 3rd infraorbital with no suborbital shelf; D IX-XI, 19-22; A II, 17-19, rarely 17; vertebrae 11+22-24, typically 23; scale rows in horizontal series about 39-51; absence of scales anterolaterally forward of verticals from dorsal-fin spines 4-6; vomerine teeth 1-3; dorsal and anal fin with a narrow dark basal stripe; and caudal fin with 4-5 dark bands. (Ref. 128653).
