Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal soft rays: 9. This species is distinguished from its congeners by the following set of characters: head wide and depressed; mouth anterior tip above level of lower eye edge; posterior angle of jaw ending posteriorly below posterior iris; suborbital longitudinal row b anteriorly ending distant behind the vertical to the posterior edge of eye; absence of a transverse rows c above or below row b; six suborbital transverse c rows of sensory papillae; suborbital longitudinal row d divided; and anterior dorsal transverse row o distant at the dorsal midline from the equivalent row (Ref. 138099).
Body shape (shape guide): elongated; Cross section: oval.
