Chaves de identificação | Morfologia | Morfometria
Raios dorsais (total) : 19 - 22; Raios anais : 10 - 11; Vértebras: 52 - 53. This species is distinguished by the following: D 19-22; A 10-11; gill-rakers 13-15 + 33-36 (total 47-51); vertebrae 52-53; origin of pelvic fins about one-third eye diameter posterior to a vertical at rear end of dorsal fin base; colour when preserved in alcohol has the centre of scales on dorsal half of body blackish, the edges pale grey (pale edges progressively narrower posteriorly), ventral half of body abruptly silvery white; colour when fresh is iridescent blue-green dorsally on body, dark pigmentation as in alcohol preserved specimens, shading through bronze to silvery white on abdomen (Ref. 91762).
