Gray described the genus Neofelis 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.[6] 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.[7] As a result of this unusual skull anatomy, neofelids have a maximum gape of approximately 90 degrees, the biggest of extant
carnivora, a trait shared by the extinct
Machairodontinae subfamily.[9]
The Sunda clouded leopard has longer upper
canine teeth and a narrower
palate between them.[10]
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
Guangdong in southern
China.[13] Populations range from the Himalayan foothills in Nepal through mainland Southeast Asia into China.[12]
Felis diardi was first described in 1823 by
Georges Cuvier based on a skin and a drawing received from Java.[14] The Sunda clouded leopard is probably restricted to the islands of Sumatra and Borneo.[2] In Java only clouded leopard fossils were found.[15]
Leopardus brachyurus was first described in 1862 by
Robert Swinhoe based on two to three skins from Taiwan.[16] Today the
Formosan clouded leopard is considered a clouded leopard subspecies Neofelis nebulosa brachyurus.[17] It is now considered to be
extinct.[18]
Threats
Deforestation is the foremost threat for both Neofelis species.[12] 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, substantial domestic markets existed in
Indonesia,
Myanmar and
Vietnam.[19]
