Body rather slender(33.5-39.8 % SL), with maximum depth at dorsal-fin origin. Dorsal profile slightly convex over snout and straight from interorbital area to tip of supraoccipital process; slightly convex to dorsal-fin origin; straight from this point to caudal peduncle; gently concave along caudal peduncle to base of caudal-fin rays. Ventral profile of body convex from lower-jaw tip to anal-fin origin; straight to anal-fin origin; slanted dorsally to end of anal fin, and almost straight under caudal peduncle. Ventral portion of body between bases of pectoral and pelvic fins transversally rounded; ventral portion of body between origins of pelvic and anal fins more compressed laterally.</paragraph>

Pelvic-fin origin located slightly anterior to vertical through dorsal-fin origin. Anal-fin origin located just behind vertical line through base of posteriormost dorsal-fin rays.

Premaxilla bearing two series of teeth; ascending process with rather broad base and acute tip, less developed than alveolar ramus. Outer row with 2(2), 3(18*), or 4(2) pentacuspidate teeth, with slender base and slightly expanded distally; inner row with 5 distally expanded teeth, slightly concave anteriorly; symphysial tooth slender with 5 cusps, second to fourth teeth with 7-9 cusps and fifth tooth with 5-6 cusps (Fig. 2). Ascending process of maxilla broad, expanded over distal part of premaxillary alveolar ramus; laminar process of maxilla short, with 1(22*) tooth with 7-9 cusps, abruptly expanded under maxillary tooth position; ligamentum primordiale attached over horizontal line through maxillary tooth base (Fig. 2). Dentary moderately deep (aproximately 45 % of its length), with its maximum depth approximately in middle of its length; dentary with 9-10 gradually decreasing teeth, first 4 or 5 heptacuspidate, sixth and seventh penta or tricuspidate, and posterior ones tricuspidate or conical (Fig. 2).</paragraph>

Head dark dorsally, with chromatophores scattered on maxilla and anterior part of lower jaw; few chromatophores on first to third infraorbital. First humeral spot broad, vertically elongated and intensely pigmented, extended from second row of scales over lateral line to second row under lateral line. Second humeral spot rather well defined, especially over lateral line. Well defined, but rather thin, lateral stripe extended from postero-dorsal angle of opercle, through the humeral spots to end of middle caudal-fin rays; the lateral stripe is sligthly expanded vertically at caudal peduncle, although not forming a conspicuous spot. Dense chromatophores located under proximal and medial surface of scales of dorsum, leaving distal area lighter, forming thus a reticulate pattern. Scales of flanks with a thin line of melanophores in its distal border. Pectoral and pelvic fins hyaline. Dorsal, anal, and caudal fins hyaline, with chromatophores scattered on membrane, more densely concentrated distally, especially evident in membranes of caudal fin.</paragraph>
