背棘 (总数) : 1; 背的软条 (总数) : 5; 臀鳍软条: 9 - 10; 脊椎骨: 31 - 32. Diagnosed by the following characters: space between anterior nostril and base of nasal barbel about equal to nostril diameter; anterior and posterior nostrils relatively small (diameter less than that of eye); anterior nostril located at end of short tube; jaws subequal (lip of upper jaw projecting past lower jaw); caudal fin emarginate (not strongly forked); eye dorsolateral, not protruding above head when viewed from side; large depression below eye; posterior edge of pectoral spine with three small serrae (much less than half width of spine); and top
of head flat, lacking conspicuous concavity and bony ridges (Ref. 75761).
Body shape (shape guide): elongated.
Inhabits small patch of vegetation in a sandy run in a sand- and gravel-bottomed, clear river with an average width of about 30 m (Ref. 75761).
