<paragraph id="27D34F3D738C0BA3C0BA61D5C9614DFB" pageNumber="23">Description. Morphometric data are presented in Table 1. Body depressed from snout to dorsal-fin origin, and posteriorly compressed. Profile gently convex from snout tip to dorsal-fin origin, slightly inclined upwards. Dorsal-fin base profile more pronouncedly convex, due to well developed musculature. Profile from dorsal-fin end to adipose-fin end almost straight (not considering adipose fin), inclined downwards. Dorsal profile more straight in young specimens (Fig. 2). Ventral profile from tip of lower jaw to anal-fin end slightly convex, almost straight. More straight on isthmus region. Profile pronounced convex in young specimens from pectoral girdle to pelvics, and from this point to anal-fin origin (Fig. 2). Procurrent rays present just after adipose and anal fins. Head large, its length about 3 times in SL; its width greater than its depth. Mouth terminal, with lower jaw a little shorter than superior. Adductor mandibulae muscles and rictal fold at the corners of the mouth well developed, giving thickset appearance to head and lower jaw. Opercular membrane large and well developed. Eye relatively small, in upper lateral position and covered by skin. Tubular anterior nostril over lip. Maxillary barbel surpassing distal opercle edge, sometimes reaching vertical through dorsal-fin origin in young specimens. Outer mental barbel reaching pectoral-fin base. Anterior cranial fontanelle extending slightly beyond posterior orbit border. Dorsal fin trapezoidal, with posterior border rounded and origin situated before midpoint of standard length; not reaching adipose-fin origin when adpressed; first lepidotrichium (“spinelet”) small and rigid, forming dorsal-fin locking mechanism; second ray elongated, forming spine; six branched rays. Adipose fin slightly elongated, with posterior border angular and free. Pectoral fin triangular, not reaching pelvic-fin origin when adpressed; first ray rigid and strongly serrate on both sides; six branched rays. Pelvic fin rounded, originating just after vertical through dorsalfin end, reaching anal-fin origin when adpressed; one unbranched and five branched rays. Anal fin rounded, its base length smaller than adipose-fin base; three to five unbranched rays and six or seven branched ones. Caudal fin almost rounded, with rounded lobes, with upper lobe longest in smaller specimens; 13 branched rays. Lateral-line pores present until just beyond adipose-fin end. Eight to eleven total gill rakers. Axillary pore absent.</paragraph>

Largest specimen, the holotype, dark-brown with blotches light-brown irregularly disposed on dorsal, pectoral, pelvic and anal fins; adipose-fin anterior and posterior borders, nape, adductor mandibulae muscles region, and median region of the flank lighter than other parts of the trunk; caudal fin entirely dark-brown. Smaller specimens (three paratypes) with coloration pattern of body and pectoral and pelvic fins dark-blotched. Regions of head, just after nape, below dorsal and adipose fins, and caudal-fin base darkened by concentration of dark dots. Dorsal and anal fins dark with median hyaline band. Smaller specimens have a dark-colored tail similar to the holotype.</paragraph>
