| Notas | Sexually mature males lack row of spines on first to tenth branched anal-fin rays, without spines on simple rays, each ray with 5-11 spines, located on basal. Middle and posterior-most branches,11-23 large spines on all branched rays of pelvic fin, located on both branches of rays extending on to anterior-most part. Males have caudal peduncle more swollen and caudal-fin rays thicker than females. Males have lateral stripe darker and more prominent than females. Males have higher concentration of melanophores along posterior margins of scales that, strongly concentrated along the lateral band and also along infraorbital, opercular and lateral surface of the cranium (vs. lighter pigmentation pattern, with the humeral and peduncular regions pigmented, in females) (Ref. 93958). |

| Diagnose |
This species differs from all its congeners by having a dark lateral stripe overlaid with a peduncular spot and a reticulated pattern on the sides of the body (vs. peduncular spot and other body pigments not superimposed over a dark lateral stripe). Other diagnostic characters include the following: three simple dorsal–fin rays, the first only visible in cleared and stained material and articulated, along with the second simple ray, with the first dorsal pterygiophores; third simple ray longer, and articulated with second dorsal pterygiophores (vs. only two simple dorsal–fin rays, both articulated with first dorsal ptery¬giophores); and anterior frontals both separated and so the fontanel front parietal continues on the mesethmoid (vs. anterior tips of frontals united and fontanel front parietal no continued on the mesethmoids) (Ref. 93958). Description: Anal-fin rays iii-iv, 24-28 (Ref. 93958). |
