Dorsum of head flat; entire body without scales and no color; absence of cephalic lateral-line system; caudal fin truncate (Ref. 75196). Anterior section of body strong and long, cylindraceous but slightly depressed, posterior part compressed; head wide and rounded, depressed; barbels 3 pairs, rostral one 2 pairs and maxillary one 1 pair.
