Cypriniformes is an order of ray-finned fish, which includes many families and genera of cyprinid fish, such as barbs, gobies, loaches, botias, and minnows. Cypriniformes is an "order-within-an-order", placed under the superorder Ostariophysi—which is also made up of cyprinid, ostariophysin fishes. The order contains 11–12 families, over 400 genera, and more than 4,250 named species; new species are regularly described, and new genera are recognized frequently. Cyprinids are most diverse in South and Southeast Asia and are entirely absent from Australia and South America. At 112 years old, the longest-lived cypriniform fish documented is the bigmouth buffalo.

This species is endemic to China where it is found in the Yuan Jiang in Hunan, Qing Jiang in Hubei Province) and the Daninghe River in Sichuan. One study found that there were no discernible differences between the specimens of this species and the types of R. mutabilis suggested that R. mutabilis is s senior synonym of R, luxiensis. Eschmeyer's Catalog of Fishes, however, recognises both these taxa as valid species.
Gymnocypris firmispinatus is a species of fish in the Cyprinidae family. The species is found in both the Jinsha River and the Lancang River in China.
