Acinonyx
Acinonyx is a genus within the cat family. The only living species of this genus, the cheetah, A. jubatus, occurs in open grasslands of Africa and Asia.
Historical range
Only one species of Acinonyx is currently living: A. jubatus, the cheetah. Several other species of cheetah-like cats have existed since the late Pliocene epoch but have become extinct. These cats occupied not only Africa, but parts of Europe and Asia as recently as 10,000 years ago. Several similar species, classified in the genus Miracinonyx, lived in North America at the same time; however, these may have been more closely related to pumas.
Taxonomy
Acinonyx was first described by Brookes in 1828. In 1993, it was placed in a monophyletic subfamily, Acinonychinae, and is considered a close sister group of the genus Puma.
Species
Several fossil Acinonyx species in addition to the living cheetah have been described:
