Prionailurus
Prionailurus is a genus of spotted, small wild cats native to Asia. Forests are their preferred habitat; they feed on small mammals, reptiles and birds, and occasionally aquatic wildlife.

Taxonomy
Prionailurus was first proposed by the Russian explorer and naturalist Nikolai Severtzov in 1858 as a generic name for a single felid occurring in tropical Asia, namely Felis pardachrous described by Brian Houghton Hodgson — the leopard cat. As varieties, Severtzov lists Felis nipalensis described by Thomas Horsfield and Nicholas Aylward Vigors, Leopardus Elliotti, Leopardus Horsfieldi and Leopardus chinensis described by John Edward Gray, and Felis bengalensis described by Anselme Gaëtan Desmarest.
The British zoologist Reginald Innes Pocock recognized the taxonomic classification of Prionailurus in 1917. In 1939, he described the genus on the basis of skins and skulls, and compared these to body parts of Felis. Prionailurus species are marked with spots, which are frequently lanceolate, sometimes rosette-like, and occasionally tend to run into longitudinal chains, but never fuse to form vertical stripes as in Felis. Skulls of Prionailurus are lower and less vaulted than of Felis. The facial part is shorter than the cranial, and the bottom of the orbit longer. The nasal bones are not everted above the anterior nares, and the outer chamber of the bulla is much smaller than the inner. Pocock classified the leopard cat, rusty-spotted cat and fishing cat as belonging to the genus Prionailurus.
Pocock's classification of Prionailurus has been widely accepted, with five species now recognised:
| Common name | Scientific name and subspecies | Range | Size and ecology | IUCN status and estimated population |
|---|---|---|---|---|
| Leopard cat
| Prionailurus bengalensis (Kerr, 1792) Two subspecies
| continental South, Southeast and East Asia. | Size: Habitat: Diet: | LC
|
| Sunda leopard cat
| Prionailurus javanensis (Desmarest, 1816) Two subspecies
| Sundaland islands of Java, Bali, Borneo, Sumatra and the Philippines | Size: Habitat: Diet: | |
| Flat-headed cat
| Prionailurus planiceps (Vigors & Horsfield, 1827) | Thai-Malay Peninsula, Borneo and Sumatra. | Size: Habitat: Diet: | EN
|
| Fishing cat
| Prionailurus viverrinus (Bennett, 1833) | South and Southeast Asia | Size: Habitat: Diet: | VU
|
| Rusty-spotted cat
| Prionailurus rubiginosus (Geoffroy Saint-Hilaire, 1834) | Nepal, India and Sri Lanka | Size: Habitat: Diet: | NT

Molecular analysis of leopard cat populations indicates a clear distinction between northern populations from Tsushima, Korea, Siberia, China and Taiwan and Southeast Asian populations. If these genetic differences indicate a specific distinction, P. b. euptilurus may yet be a valid species. The Iriomote cat (P. bengalensis iriomotensis) has been proposed as a distinct species based on morphology, but is considered a subspecies of P. bengalensis based on genetic analysis.
Phylogeny
Phylogenetic analysis of the nuclear DNA in tissue samples from all Felidae species revealed that the evolutionary radiation of the Felidae began in Asia in the Miocene around 14.45 to 8.38 million years ago. Analysis of mitochondrial DNA of all Felidae species indicates a radiation at around 16.76 to 6.46 million years ago. Both models agree in the rusty-spotted cat having been the first cat of the Prionailurus lineage that genetically diverged, followed by the flat-headed cat and then the fishing cat. It is estimated to have diverged together with the leopard cat between 4.31 to 1.74 million years ago and 4.25 to 0.02 million years ago.
