Espinhos dorsais (total) : 0; Raios dorsais (total) : 108 - 114; Espinhos anais: 0; Raios anais : 92 - 97. No lateral line on ocular side. Light brownish on ocular side, with 9 to 10 indistinct dark bands; posterior parts of dorsal and fin membranes blackish; no black blotch on dorsal and anal fins and opercle (Ref. 27363).
