Head depressed, dorsal profile slightly convex up to level of posterior fontanel, then evenly sloping at angle of 20–25° to horizontal. Ventral profile slightly convex up to pelvic fin origin, almost straight after it. Bony elements of dorsal surface of head covered with thin skin; bones readily visible, especially on posterior half of neurocranium, ornamented with numerous fine, radial grooves. Midline of cranium with elongate fontanel extending from behind snout to base of supraoccipital spine. Anterior fontanel short with shallow cavity, posterior fontanel elongated. Supraoccipital process elongate, with gently converging sides, its tip blunt; extending to anterior nuchal plate. Eye ovoid, horizontal axis longest, its margin free; located entirely in dorsal half of head. Gill openings wide, extending from posttemporal to beyond isthmus. Gill membranes free from isthmus. Six branchiostegal rays. First branchial arch with 6+18 (1) gill rakers. Mouth subterminal, upper lip fleshy, upper lip extending anteriorly beyond upper jaw. Oral teeth small, villiform, in irregular rows on all tooth-bearing surfaces. Premaxillary teeth irregularly arranged in 2–3 rows, tooth band curved. Dentary tooth band narrower than premaxillary tooth band at symphysis, tapering laterally. Barbels in four pairs. Maxillary barbel long, moderately thick, extending to vertical through posterior of anal-fin base. Nasal barbel slender, extending to midway between posterior orbital margin and dorsal-most point of gill opening. Inner mandibular-barbel origin close to midline; barbel slender, extending to level of pectoral-fin origin. Outer mandibular barbel originating posterolateral of inner mandibular barbel, extending to midway between base of last pectoral-fin ray and pelvic-fin origin.
