简单描述
型态特徵 | 形态测量图
背棘 (总数): 1; 背的软条 (总数): 6; 臀鳍软条: 12 - 14. Body moderately elongate (Ref. 47263). A deep head, its height more than 66% of the head length (Ref. 47263). An obtusely pointed snout, slightly rounded (Ref. 47263). Eye-diameter longer than the length of the nasal barbel (Ref. 47263). 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 (Ref. 47263). A low number, 13-14, of slender gill rakers (Ref. 47263). Humeral spine well developed, but not reaching beyond the level of the dorsal spine (Ref. 47263). Dorsal spine short, strongly serrated on the posterior side; pectoral spine well developed, strongly serrated on the inner side (Ref. 47263). 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 (Ref. 47263). Adipose fin small, the length of its base shorter than the length of the base of the dorsal fin (Ref. 47263). Preserved specimens are dark brown above the lateral line and lighter beneath; sometimes there is a black band behind the operculum (Ref. 47263). The dorsal and caudal fin may show a tiny black margin (Ref. 47263).
