Maxillary barbels shorter than head, unbranched and without tubercles, but with a distinct narrow membrane basal half of their anterior margins; outer mandibular barbels with few, simple and rather short ramifications; branches of inner mandibular barbels more numerous, subdivided and globose (Ref. 57223). Mandibular teeth strong and rather long, numbering 17-22 (Ref. 57223). Pectoral-fin spines finely denticulate, the serrations being stronger on inner than on outer margin; dorsal-fin spine anteriorly smooth (Ref. 57223). Humeral process deep, triangular, granulose and not keeled ventrally (Ref. 57223). Adipose fin very well developed and close to rayed dorsal fin (Ref. 57223).Colour: After preservation, the colouration becomes entirely light beige, with numerous small, dark specks (Ref. 57223). Live specimens are entirely yellow, with a dense pattern of black specks covering body and adipose fin; other, more widely spaced specks are found on fins (Ref. 57223).
