Ichneumon javanicus was the
scientific name proposed by
Étienne Geoffroy Saint-Hilaire in 1818. It was later classified in the genus
Herpestes, but all Asian mongooses are now thought to belong in the genus
Urva. In the 19th and 20th centuries, several
zoological specimens were described, which are now considered
subspecies: •
Herpestes exilis by
Paul Gervais in 1841 was a specimen from
Tourane in Vietnam. •
Herpestes rafflesii by
John Anderson in 1875 was a specimen from Sumatra. •
Mungos rubifrons by
Joel Asaph Allen in 1909 were eight adult specimens collected around
Wuzhi Mountain in
Hainan Island, China. •
Mungos exilis peninsulae by
Ernst Schwarz in 1910 was a skin and a skull of a mongoose collected in Bangkok. •
Mungos siamensis by
Cecil Boden Kloss in 1917 was a skin of an adult female mongoose collected in northern Thailand. •
Mungos parakensis by Kloss in 1917 was a skin and a skull of an adult female mongoose from the vicinity of
Taiping, Perak in Peninsular Malaysia. •
Herpestes javanicus tjerapai by
Henri Jacob Victor Sody in 1949 was an adult male mongoose collected in
Aceh Province, Sumatra. The
small Indian mongoose (
U. auropunctata) was once considered to be a
subspecies of the Javan mongoose. Genetic analysis of hair and tissue samples from 18 Javan and small Indian mongooses revealed that they form two
clades and are distinct species. The
Salween River in Myanmar is probably a barrier between the two species. Analysis of
mitochondrial DNA of
Urva species revealed that the Javan mongoose forms a
sister group with the
Indian grey mongoose (
U. edwardsii). The Javan mongoose probably evolved about in the
middle Miocene. ==Description==
