Épines dorsales (Total) : 11; Rayons mous dorsaux (Total) : 17 - 18; Épines anales: 2; Rayons mous anaux: 17; Vertèbres: 22 - 23. This species is distinguished from its congeners by the following set of characters: rigid upper jaw with no flexible lamina posteriorly, extending 0.6-0.7 eye diameters behind posterior margin of orbit; infraorbitals moderately slender, 2nd and 3rd infraorbitals relatively large, with large sensory canal openings, 3rd infraorbital with moderate suborbital shelf; D XI, 17 or 18; A II, 17; vertebrae 10+22 or 23; scale rows in horizontal series about 45-49, scales absent anterolaterally forward of verticals from segmented dorsal-fin rays 4-5; vomerine teeth 2 or 3; spinous dorsal fin with an ocellus between spines 2-7 (Ref. 128653).
Body shape (shape guide): elongated; Cross section: compressed.
