An obtusely pointed snout, slightly rounded. Eye-diameter longer than the length of the nasal barbel. Nasal barbel short, hardly reaching the anterior edge of the orbit; maxillary barbel moderate reaching the tip of the humeral spine; outer mandibulary barbel moderate, up to the posterior end of the operculum; inner mandibulary barbel reaching the end of the orbit; the two pairs of slender mandibulary barbels are distantly set and in between small papillae are found. A low number, 13-14, of slender gill rakers. Humeral spine well developed, but not reaching beyond the level of the dorsal spin. Dorsal spine short, strongly serrated on the posterior side; pectoral spine well developed, strongly serrated on the inner side. Dorsal fin short, much shorter than the head length; pectoral fin short, not reaching the base of the ventral fin; anal fin moderate, its base longer than or equal to the base of the adipose fin.
