. It distinctly differs from this genus, however, in having a pair of well-developed maxillary barbels and in its lower lip being divided into two small lateral and translucent fleshy lobes and one central plate. There are no known cyprinids with mouths of similar structure to that of the fish of this new genus. In the lower jaw of the new genus, the dentary is transversely L-shaped in ventral view, as the anterior part forms a right-angle turn and the transverse branch is anterioposteriorly expanded (
