Description. Body moderately elongated and compressed. Snout bluntly rounded; tubercles irregularly arranged on tip of snout to lacrimal bones and visible with bare eyes. Several mature males in breeding condition have been observed having extensive tuberculation on the head, posterior half of body, and anal fin ( Fig. 5 ). Mouth subterminal, lower jaw shape varies from rounded to truncated, lower jaw always subequal to upper jaw. Most species have yellowish horny sheath on lower lip, two pairs of well-developed barbels (rostral and maxillary); few species have small maxillary barbels; one species has no barbels. Dorsal-fin rays iv, 7–8 with last simple ray ossified and serrated posteriorly. Pectoral-fin rays i, 12–16, with first ray longest; pelvic-fin rays i, 8 (rarely 7), with first ray being longest; anal-fin rays iii, 5, pointed with third ray longest. Most species have bold black or dusky submarginal stripes on upper and lower caudal-fin lobes; stripe in lower lobe tends to be bolder than in the upper one. See Roberts (1998) for detailed description.
