Identification. Body moderately elongated and relatively deep. Maxillary barbel parallel to main body axis, crossing the pelvic-fin insertion. Dorsal-fin base (14.4– 19.4% SL). Adipose fin long (35.9–43.2% SL) and deep (4.1–7.5% SL), forming elevated curve in lateral profile. Insertion of the adipose fin closer to the dorsal fin than to the caudal fin. Caudal fin forked with both lobes rounded, lower lobe slightly longer than upper lobe. Body usually brown. In some specimens a dark lateral stripe along the lateral line is present ( Hernández et al. 2015).
