Genera
[edit | edit source]Schizopygopsinae contains the following genera:[3]
- Schizopyge Aspiorhynchus
- Kessler, 1879 Steindachner, 1866
- Heckel, 1847 Schizothorax
- Percocypris Heckel, 1838
- Diptychus Y. T. Chu, 1935
Three fossil genera are also known, all from the Tibetan Plateau:[4]
- †Hsianwenia Chang et al, 2008 (Pliocene of China)
- †Paleoschizothorax Yang et al., 2018 (Oligocene of China)[5]
- †Plesioschizothorax Wu & Chen, 1980 (Miocene of China)
Fossils of Paleoschizothorax suggest that early schizothoracines originally inhabited the large, swampy river basins, such as the Qaidam Basin, that existed on the Tibetan Plateau prior to significant uplift of the Himalayas. Following the uplift of the mountain range, many schizothoracines became adapted to fast-flowing high altitude rivers. Others, such as Schizothorax species found in southern China, continued to inhabit a low-lying subtropical environment.[5]
