Schizopygopsis is a genus of cyprinid fish. Most species are endemic to river basins in the Himalaya s and Qinghai–Tibet Plateau of China, but S. stoliczkai extends into the highlands of Afghanistan, Iran, northern India, Kyrgyzstan, Pakistan and Tajikistan.[1][2]
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.[1] Similar to Platypharodon, 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.[3][4]
Schizopygopsis is a part of the schizothoracines (snowtrout and allies), which also includes the genera Aspiorhynchus, Chuanchia, Diptychus, Gymnodiptychus, Gymnocypris, Oxygymnocypris, Platypharodon, Ptychobarbus, Schizopyge and Schizothorax.[5]
