It is distinguished from all congeners by the presence of a lachrymal plate that extends ventrally to cover a portion of the upper lip (Ref. 57663). Body deep and laterally compressed (Ref. 57663). Two inner rows of teeth in both upper and lower jaws (Ref. 57663). It has cycloid scales above the upper lateral line on the flanks (Ref. 57663). In life, adults are uniformly gray brown, paler ventrally and lacking any obvious body markings (Ref. 57663).
