Acinonyx is a genus within the cat family.[1] The only living species of this genus, the cheetah, A. jubatus, occurs and thrives in open grasslands of Africa and Asia.[2] Though often described as a big cat, this term is used primarily to describe cats of the genus Panthera, ruling out the cheetah.
Historical range[edit]
Several other species of cheetah-like cats existed since the late Pliocene epoch but are extinct today.[3] These cats occurred in Africa, parts of Europe and Asia about 10,000 years ago. Several similar species, classified in the genus Miracinonyx, lived in North America at the same time; these may have been more closely related to pumas.[4]
Taxonomy[edit]
Acinonyx was first described by Brookes in 1828. In 1993, it was placed in a monophyletic subfamily, Acinonychinae. Molecular phylogenetic analysis has shown that it is the sister group of the genus Puma, and it is now placed within the subfamily Felinae.[1]
Between the late 18th century and the early 20th century, the following Acinonyx species and subspecies were described:[5]
- Acinonyx jubatus — by Schreber in 1775[6]
- Acinonyx jubatus jubatus — the nominate subspecies[5]
- Acinonyx jubatus venaticus — by Griffith, 1821
- Acinonyx jubatus soemmeringii — by Fitzinger, 1855
- Acinonyx jubatus hecki — by Hilzheimer, 1913
In addition, the following fossil Acinonyx species were dscribed:
- Acinonyx pardinensis †, the giant cheetah — by Croizet et Jobert in 1828[7]
- Acinonyx intermedius † — by Thenius in 1954[8]
- Acinonyx aicha † — by Geraads in 1997[9]
- "Acinonyx kurteni"† — by Christiansen and Mazák in 2008[10] The "Linxia Cheetah" was originally described from a skull from Pliocene strata in China, and touted as the most primitive member of the genus. In 2012, A. kurteni was invalidated as a species when the holotype was determined to be a forgery composed of Miocene-aged fragments.[11][12]
