The type locality is the Koshi , a tributary of the Ganges . Specimens caught further east, e.g. B. in Thailand or Burma belong to other, previously undescribed Oreichhys species.
features
The Indian sailfin barbel has a barbel-typical shape, is slightly high-backed and is four to eight centimeters long. It differs from all other barbel of the genus Oreichhys by the lack of the dark spot on the caudal fin stalk. In contrast to the other species of the genus, it does not show any conspicuous sexual dimorphism . The sideline is short and only extends over two to three pored scales. The head sides are provided with 11 to 13 conspicuous rows of pores . The pharyngeal teeth are in three rows: 1-3-4. The anal fin has a central dark spot that is triangular in the adult animals. The dorsal fin has a white tip and a white outer edge.
