Gray described the genusNeofelis as having an elongate skull, a broad and rather produced face on the same plane as the forehead, a large and elongate nasal, a moderate orbit, a truncated lower jaw and very long conical upper and lower canine teeth with a sharp cutting hinder edge. This skull has resemblances to that of the fossil Smilodon, with very much elongated upper canines. Pocock described the skull of Neofelis as recalling in general features that of Panthera pardus, especially in the shortness and wide separation of the frontal and malar postorbital processes, relative proportion of mandibular teeth; but differing in the greater posterior width of the nasals, the thicker, more salient inferior edge of the orbit, and the mandible being greatly elevated anteriorly. The Sunda clouded leopard has longer upper canines and a narrower palate between them.
Between 1821 and 1862, several felids have been described from Southeast Asia that are subordinated under Neofelis today:
Felis nebulosa was first described in 1821 by Edward Griffith based on a specimen brought from Canton in southern China. Populations range from the Himalayan foothills in Nepal through mainland Southeast Asia into China.
Felis diardi was first described in 1823 by Georges Cuvier based on a skin and a drawing received from Java. The Sunda clouded leopard is probably restricted to the islands of Sumatra and Borneo. In Java only clouded leopard fossils were found.
Leopardus brachyurus was first described in 1862 by Robert Swinhoe based on two to three skins from Taiwan. Today the Formosan clouded leopard is considered a clouded leopard subspecies Neofelis nebulosa brachyurus. It is now considered to be extinct.
Threats
is the foremost threat for both Neofelis species. They are also threatened by commercial poaching for the wildlife trade. Skins, claws and teeth are offered for decoration and clothing, bones and meat as substitute for tiger in traditional Asian medicines and tonics, and live animals for the pet trade. Few poaching incidents have been documented, but all range states are believed to have some degree of commercial poaching. In recent years, substantialdomestic markets existed in Indonesia, Myanmar and Vietnam.
Conservation
Both Neofelis species are listed in CITES Appendix I and are protected over most of their range. Hunting is banned in Bangladesh, Brunei, Cambodia, China, India, Indonesia, Malaysia, Myanmar, Nepal, Taiwan, Thailand, and Vietnam. Hunting regulations apply in Laos.
