Characters
Head is high and very broad, snout is rather short and broad. Rostral projection is directed slightly laterally and bears a small spine on base. Nasal spine is present in juveniles but not in adults. Lower jaw has a single serrated ridge. Lip barbels are finely pointed, number 5 or 6 to 12, and are arranged in two clusters of 3 to 6. Chin barbels are flattened and sharp pointed, number 12 to 18, and are arranged in four clusters. Filamentous mandibular barbel is slightly longer than longest chin barbel. Perifacial rim is rather narrow. Gill rakers number 2 on upper limb and 18 to 22 on lower limb. Measurements are expressed as percent of SL: head length 37%–42%, head depth 19%–21%, rostral projection length 6%–7%, snout length 15%–16%, orbit length about 9%, interorbital width about 10%, mandibular barbel length 10%–14%, first free pectoral fin ray length 20%–24%, first joined pectoral fin ray length 20%–22%, body depth 20%–22%. Joined pectoral rays number 12. First dorsal fin has seven spines, and second dorsal fin has 15 rays. Anal fin has 16 rays. Scutes in dorsal series number 26, in supramedian series number 32, in inframedian series number 23, and in ventral series number 21, with anterior pointed end of first ventral scute on line with or anterior to anterior edge of bony knob of pelvic girdle.
Color in preservative is yellowish, with mottled spotting on pectoral fin.
