Raggi dorsali molli (totale) : 13 - 14; Raggi anali molli: 11 - 12; Vertebre: 44. Pale, straw-colored ground color. Opercle and snout dusky. Dark pigment distributed on margins of scale pockets (Ref. 37473). Slender body, smoothly narrowed toward the end of caudal peduncle. Maximum depth at the level of the pectoral fin base for 39-69 mm specimens and immediately before the dorsal fin origin for larger ones. Pectoral fins short, not reaching origin of dorsal fin. Operculum without radial grooves. No gill rakers at the inner surface of epibranchial of first gill arch. Swim bladder absent (Ref. 33679).
