Schizopygopsis

Schizopygopsis is a genus of cyprinid fish. Most species are endemic to river basins in the Himalayas and Qinghai–Tibet Plateau of China, but S. stoliczkai extends into the highlands of Afghanistan, Iran, northern India, Kyrgyzstan, Pakistan and Tajikistan.^[2][3]

S. younghusbandi is up to almost 50 cm (1.6 ft) in total length, but the remaining species generally only reach about two-thirds of that size.^[2] Schizopygopsis have a horny sheath on the lower jaw and spoon-shaped teeth that they use to scrape off periphyton and algae from stones, but they will also eat benthic invertebrates.^[4][5]

Schizopygopsis has been classified as a part of the schizothoracines (snowtrout and allies),^[6] however, Eschmeyer's Catalog of Fishes classifies this genus in the subfamily Schizopygopsinae.^[1]
