Morphology | Morphometrics
soft rays: 20;
Vertebrae: 36 - 37. The males of this species are unique among the species of its congeners in having a bright orange flag on the distal one-third to one-fourth of the anterior region of the spinous dorsal fin, the color is mostly confined to between the first and third spines (tapering in some larger specimens to terminate posteriorly between third and fourth spines, with much less orange color in the tapering region) and without a chalky white band along the ventral margin of the orange flag; modally with 3 mandibular sensory pores (Ref. 78428).
