Short description Morfología | Morfometría

Espinas dorsales (total): 14 - 16. Distinguished uniquely from its congeners by its body depth, 27-30% SL. Differs further from other species of the genus by the combination of the following characters: flank grey with a few large, irregular, dark blotches; and dorsal fin with 14-16 spines (Ref. 59043).
