Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 2; Raios dorsais (total) : 9; Espinhos anais: 4; Raios anais : 20 - 22; Vértebras: 33. Color pattern on body reticulated, formed by dark pigmentation along the posterior portion of the scales. A horizontally elongate black stripe extends from a vertical through the last anal fin ray to tips of middle caudal fin rays. The caudal peduncle stripe is not preceded by a light area as that on M. oligolepis. The anterior humeral blotch is uniformly pigmented along its length. Lateral line incomplete (Ref. 41101).
Body shape (shape guide): short and / or deep; Cross section: compressed.
