Morphometrics are presented in Table 2. The fin ray counts are as follows: dorsal fin II,6 (1), II,7 (11); pectoral fin I,8 (7), I,9 (5); pelvic fin i,5(8), i,6 (1). The head is large with the dorsal edge in the lateral profile rising steeply from the tip of the snout to the dorsal-fin origin; the ventral edge is straight from the tip of snout to the lower posterior margin of the opercle. Body depth is greatest at the dorsal-fin origin. The dorsal-lateral profile descends less steeply from the dorsal-fin origin to the caudal peduncle with a slight rise and descent under the adipose fin. The minimum caudal-peduncle height is at the posterior edge of the base of the adipose fin. The ventral-lateral profile from the rear of the head to the anal fin is flat and concave at the caudal peduncle. In adults the leading lateral edges of the nuchal plates are straight or slightly curved (

The dorsal spine is stout and nonserrated on the posterior edge. The distal edge of the pectoral fin is straight to slightly convex. The pectoral spine is stout and serrated on the posterior edge. The distal edge of the pelvic fin is convex with the second branched ray being the longest ray. The rays of the anal fin are much longer than the base, and the second or third branched ray is longest. The distal edge of the caudal fin is round to weakly emarginated.</paragraph>

The maxillary barbel is darkly pigmented and the mandibular barbels are white or slightly brown. The sides and top of the head are brown and without spots.
