This species is distinguished by the following characters: D VIII,9; pectoral fins 15-16; gill rakers 7-8 + 19-21 = 27-29; lateral line scales 36-38; body depth at first dorsal fin origin 25-29% SL and at anal-fin origin 21-24% SL; caudal-peduncle depth 9.9-12% SL; maximum head depth 21-26% SL; head depth through eye 18-20% SL; head length 30-31%SL; orbit length 7.0-8.7% SL; upper jaw length 11-13% SL; barbel length 17-21% SL; caudal-fin length 26-30% SL; anal-fin height 15-16% SL; pelvic-fin length 18-21% SL; pectoral-fin length 22-24% SL; first dorsal-fin height 22-25% SL; second dorsal-fin height 14-16% SL; 7-9 total bars on caudal fin, 4-5 brown or dark brown bars on upper caudal-fin lobe, 3 (rarely 4) bars on lower lobe, increasing distally in width with the widest distal-most bar black or dark brown, while the other bars are pale brown or brown; width of largest lower caudal-fin lobe bar and/or pale interspace between distal-most bars equal to or larger than orbit; tip of lower fin lobe pale (bars on both caudal-fin lobes retained on preserved fish); tip of first dorsal-fin dark, the vertical length of the pigmented area similar in size to width of widest lower caudal-fin lobe bar; 2 yellow or pale brown mid-lateral body stripes, one from eye to caudal-fin base, where it joins the proximal upper caudal-fin lobe bar, and the other stripe below from pectoral-fin base to caudal peduncle and continued by proximal-most lower caudal fin lobe bar; 2 dorsolateral brown or pale brown stripes, with the lower one distinct and well-separated from pale body surface, extending from operculum to behind second dorsal fin, the upper one indistinct or hidden and much shorter, beginning below first dorsal-fin origin and bordered dorsally by a horizontal series of pale spots (lateral body stripes not retained on preserved fish); barbels white; white to silvery body. Dark reddish-brown dorsally, white belly, faint yellowish patches along pelvic and anal-fin bases (body pale brown in preserved fish, slightly darker above lateral line) . Body shape (shape guide): fusiform / normal;  Cross section: oval.
