| Notas | Sexually mature males (2.51-2.78 cm SL), with pelvic-fin bony hooks all over the five larger branched pelvic-fin rays, including its ramifications, with just one hook centered at the medial surface of each ray segment, anteromedially projected; anal-fin hooks bilateral, smaller than those observed on the pelvic-fin rays, only along the posterior ramification of the first four branched rays, positioned at the posterior surface of the anal-fin rays, with 1-2 pairs of hooks on each ray segment, posterodorsally oriented; the last unbranched and first seven branched anal-fin rays are hypertrophied, as are the ventral procurrent caudal-fin rays, which are laminar and extend ventrally through the musculature and skin; anterior region of the anal-fin base, from its origin to the ninth branched anal-fin ray, is strongly convex, in a distinctly oblique position relative to the posterior anal-fin base region; posterior region of the body, posterior to the ninth branched anal-fin ray, is slightly ventrally arched (Ref. 130247). |

| Diagnose |
This species is distinguished from its congeners by the following characters: with anterior midlateral stripe reaching the caudal peduncle blotch (vs. stripe reaching the dorsal-fin region); proximal half of second unbranched dorsal-fin ray is densely pigmented (vs. hyaline or barely pigmented); caudal peduncle blotch round (vs. triangular); complete lateral line (vs. incomplete); higher number of longitudinal scales, 37-38 (vs. 31-33 in lindeae, 33-36 in lu); ventral margin of third infraorbital bone surpassing anterodorsal margin of preopercle (vs. usually reaching that point); precaudal vertebrae 13 (vs. 12); differs further from lu, by the dense concentration of dark brown chromatophores over the first unbranched dorsal and all unbranched anal-fin rays (vs. unbranched fin rays of both poorly pigmented); with two symmetrical conspicuous small dark blotches at the base of the caudal-fin rays (vs. usually absent, but when present, very diffuse); circumpeduncular scales 12 (vs. 10-11), and pectoral-fin rays i9-11 (vs. i8) (Ref. 130247). |
