Head depressed, longer than wide, triangular in dorsal view. Cheek muscles slightly bulging externally in lateral contour of head. Eye small, dorsolateral on middle of head. Eye rim not free, covered by thin and translucent skin, continuous with head skin. Mouth subterminal, relatively narrow. Upper lip with minute papillae immediately anterior to premaxillary teeth. Lower lip with large rectangular lateral lobes located posteromedially to rictal barbel base. Premaxillary teeth conical, arranged in three irregular rows. Dentary teeth conical, similar in size to those of premaxilla, arranged in three irregular rows near symphysis and one row to posterior region of dentary. Anterior nostril medially surrounded by fleshy flap, increasingly deeper posteriorly and laterally continuous with nasal barbel. Posterior nostril closer to anterior nostril than to eye; anterior rim delimited by thin fleshy elevated margin; posterior rim not delimited by fleshy flap, and continuous with head surface. Barbels long and flattened, tapering distally. Nasal barbel originating laterally from fleshy fold encircling anterior nostril and extending posteriorly to half-length of opercular patch of odontodes. Tip of maxillary barbel surpassing pectoral-fin base. Rictal barbel slightly shorter than maxillary barbel, with its tip reaching posterior region of pectoral-fin base. Interopercle with 42–52 odontodes, arranged in three irregular rows. Posterior interopercular odontodes of medial row largest, with distal tip medially curved. Opercular patch of odontodes large and almost circular in shape, with 21–39 conic odontodes arranged in 6–8 dorsoventral transverse rows. Opercular odontodes gradually larger posteriorly. Branchiostegal membrane supported by eight rays and joined to isthmus only anteriorly, forming a narrow free fold across isthmus. Medial most three branchiostegal rays associated with anterior ceratohyal, next three rays with interceratohyal cartilage and lateral most two rays with posterior ceratohyal. Branchiostegal rays 5–8 expanded distally (
