Prionailurus species are marked with spots, which are frequently lanceolate, sometimes rosette-like, and occasionally tending to run into longitudinal chains, but never fusing to form vertical stripes as in Felis.
Following genetic studies, the monotypic genus Otocolobus has been proposed to be placed with the genera Felis and Prionailurus in the tribe Felini, because of a close phylogenetic relationship.
His description of leopard cats from the areas of Gilgit and Karachi under the trinomen Prionailurus bengalensis trevelyani is based on seven skins that had longer, paler and more greyish fur than those from the Himalayas.
According to a 2006 genomic study of Felidae, an ancestor of today's Leopardus, Lynx, Puma, Prionailurus, and Felis lineages migrated across the Bering land bridge into the Americas about 8.0 to 8.5 million years ago.
Pardofelis are small long-tailed, short-headed cats with rounded ears, distinguishable from Prionailurus and related Oriental genera by having the skull higher and more rounded, with the mesopterygoid fossa lanceolate in front and provided with thickened margins or a better developed external crest.
Prionailurus skulls are lower and less vaulted than Felis, the facial portion is shorter than the cranial, the floor of the orbit is longer, the nasal bones are not everted above the anterior nares, the outer chamber of the bulla is much smaller than the inner.
Based on this broad variety of skins, he proposed to differentiate between a southern subspecies Prionailurus bengalensis bengalensis from warmer latitudes to the west and east of the Bay of Bengal, and a northern Prionailurus bengalensis horsfieldi from the Himalayas, having a fuller winter coat than the southern.
