Leopard Cat - Taxonomic History

Taxonomic History

In 1792, Robert Kerr first described a leopard cat under the binominal Felis bengalensis in his translation of Carl von Linné’s Systema Naturae as being native to southern Bengal. Between 1829 and 1922, different authors of 20 more descriptions classified the cat either as Felis or Leopardus. Owing to the individual variation in fur colour, leopard cats from British India were described as Felis nipalensis from Nepal, Leopardus ellioti from the area of Bombay, Felis wagati and Felis tenasserimensis from Tenasserim. In 1939, Reginald Innes Pocock subordinated them to the genus Prionailurus. The collection of the Natural History Museum in London comprised several skulls and large amounts of skins of leopard cats from various regions. 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. 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. He assumed that trevelyani inhabits more rocky, less forested habitats than bengalensis and horsfieldi.

Between 1837 and 1930, skins and skulls from China were described as Felis chinensis, Leopardus reevesii, Felis scripta, Felis microtis, decolorata, ricketti, ingrami, anastasiae and sinensis, and later grouped under the trinomen Felis bengalensis chinensis. In the beginning of the 20th century, a British explorer collected wild cat skins on the island of Tsushima. Oldfield Thomas classified these as Felis microtis, which had been first described by Henri Milne-Edwards in 1872.

Two skins from Siberia motivated Daniel Giraud Elliot to write a detailed description of Felis euptilura in 1871. One was depicted in Gustav Radde’s illustration cum description of a wild cat; the other was part of a collection at the Regent's Park Zoo. The ground colour of both was light brownish-yellow, strongly mixed with grey and covered with reddish-brown spots, head grey with a dark-red stripe across the cheek. In 1922, Tamezo Mori described a similar but lighter grey spotted skin of a wild cat from the vicinity of Mukden in Manchuria that he named Felis manchurica. Later both were grouped under the trinomen Felis bengalensis euptilura. In the 1970s and 1980s, the Russian zoologists Geptner, Gromov and Baranova disagreed with this classification. They emphasized the differences of skins and skulls at their disposal and the ones originating in Southeast Asia, and coined the term Amur forest cat, which they regarded as a distinct species. In 1987, Chinese zoologists pointed out the affinity of leopard cats from northern China, Amur cats and leopard cats from southern latitudes. In view of the morphological similarities they did not support classifying the Amur cat as a species.

The initial binomial euptilura given by Elliott was eventually changed to euptilurus referring to the ICZN Principle of Gender Agreement; at present, both terms are used.

Molecular analysis of 39 leopard cat tissue samples suggested distinction between northern leopard cats from Tsushima, Korea, Siberia, China and Taiwan, and southeast Asian leopard cats.
