Diagnosis

Broad snout, rounded, naked but for 2 spiny tubercular scales at lateral angles; small coarse scales in a series along the posterior part of the median nasal ridge; a wedge of small scales intruding forward from the interorbital region on each side of median ridge. Prominent naked margins on head bones. Reduced spinules on scales, absent along the outer margins, about 8-12 subparallel ridges, few with sharp spinules. Internasal width about 5 in head, interorbital about 4, slightly greater than orbit diameter; small barbel, about 0.5 or less into orbit; upper jaw 36-39% head length. 1D. II,8-10 (Ref. 11650).
