Characters
Head is very short and moderately depressed, and snout is relatively long and broad. Rostral projection is broad and triangular shaped and bears stout spine near base. Nasal spine is absent. Lip barbels number 5 and are arranged in three clusters of 2, 1, and 2. Chin barbels number 11 to 13 and are arranged in four or five clusters. Perifacial rim ends as broad right-angled wing. Gill rakers number 3 or 4 on upper limb, 1 in corner, and 23 or 24 on lower limb. Measurements are expressed as percent of SL: head length 34%–36%, head depth 16%–17%, rostral projection length 3%–5%, snout length 15%–16%, mandibular barbel length 16%–19%, orbit length 7%–9%, interorbital width 8%–9%, joined pectoral fin length 14%–15%, first free pectoral fin ray length 19%–21%, body depth 16%–18%. Pectoral fin has 13 or 14 joined rays. First dorsal fin has eight spines, and second dorsal fin has 16 to 19 rays. Anal fin has 17 to 19 rays. Scutes in dorsal series number 27 or 28, in supramedian series number 30 to 32, in inframedian series number 27, and in ventral series number 21 or 22, with anterior point of first ventral scute posterior to anterior edge of bony knob of pelvic girdle.
Color in preservative is pale yellow, with dusky stripes on body between scute rows, striping and spotting on head, distal half of first dorsal fin black, and distal quarter of second dorsal fin dusky.
