In 70% ethanol: Body and head brown, fading to cream ventrally. Humeral region with distinct black spot about twice as large as eye; spot overlapping on dorsoposterior corner of tympanum. Moderately large irregular darker brown patches on flanks extending from just above lateral line to base of anal fin. Some individuals with faint dark midlateral line extending along posterior two-thirds of body. Rays of dorsal, pectoral and caudal fins with dense concentration of melanophores, frequently imparting dark color to rays; melanophores sometimes extending to fin membranes of dorsal and pectoral fins. Melanophores much less dense on pelvic fins, imparting a dusky coloration to fins. Anal fin also with melanophores on fin rays; melanophores more concentrated on distal edge of fin, imparting appearance of dark margin. Tips of anal-fin rays in some individuals without pigmentation, imparting appearance of very thin pale edge to anal fin. Maxillary barbels brown throughout; mandibular barbels cream.
