Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 9 - 11; Anal soft rays: 13 - 15; Vertebrae: 31 - 32. This species differs from all congeners by having red dots on body side arranged in chevron shaped rows with angle on the midline of the flank, a broad dark grey stripe along the whole flank, flank light blue in males, dorsal and ventral portions of the caudal fin light orangish red in males, conspicuous orangish red bars on the middle of the caudal fin in males, dorsal portion of the caudal-fin base with a small vertically elongated black spot, and a black bar on the anterior and another on the posterior portion of the iris almost in contact with the pupil (Ref. 94719).
