Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 13 - 14; Radios blandos dorsales (total) : 12 - 13; Espinas anales: 3; Radios blandos anales: 8 - 9; Vértebra: 27 - 28. It is distinguished from all congeners by a unique pigmentation pattern and coloration comprising an expansive, generally vertically oriented, black band or blotched region of black pigment below the lateral midline and just anterior to the origin of the anal fin, and by an overall dark grayish-green body coloration (Ref. 57663).
