The '''Java mouse-deer''' ('''''Tragulus javanicus'''''),<ref name=msw3>{{cite web |url=http://www.bucknell.edu/msw3/browse.asp?id=14200129 |title=Tragulus javanicus |author= |date= |work=Mammal Species of the World |publisher= |accessdate=2010-03-11}}</ref> is a species of [[even-toed ungulate]] in the [[Tragulidae]] family. At maturity it is about the size of a [[rabbit]], making it one of the smallest [[ungulate]]s. It is found in forests in [[Java]] and perhaps [[Bali]], although sightings here have not been verified.<ref name=iucn/>.
==Taxonomy==
The Java mouse-deer’s common scientific name is ''Tragulus javanicus'', although other classification names for it exist, including ''Tragulus javanica'', ''Cervus javanicus'', and the [[heterotypic synonym]] ''Tragulus fuscatus''.<ref name=meijaard>Meijaard, I. and Groves, C. P. (2004). ''A taxonomic revision of the Tragulus mouse-deer.'' Zoological Journal of the Linnean Society 140: 63-102.</ref> <ref name=ARKive4>Javan mouse-deer (Tragulus javanicus). (2013).

Retrieved from http://eol.org/pages/328339/</ref> The taxonomic status of the Java mouse-deer is questionable, but recent craniometric analyses have begun to shed light on the taxonomic discrepancies. Previously, the Java mouse-deer, ''Tragulus javanicus'', was commonly thought to represent the wider class of large [[chevrotain]]s, but it was found that these, unlike the Java mouse-deer, do not likely reside on [[Java]]. Three species groups of ''Tragulus'' have been identified based on craniometric skull analyses and coat coloration patterns. These three species groups are ''Tragulus javanicus'', ''[[Tragulus napu]]'', and ''[[Tragulus versicolor]]''. Based upon these craniometric analyses, ''Tragulus javanicus'' was then further separated based on the organisms’ known geographic locations: ''[[Tragulus williamsoni]]'' (found in northern Thailand and possibly southern China), ''[[Tragulus kanchil]]'' (found in Borneo, Sumatra, the Thai–Malay Peninsula, islands within the Greater Sunda region, and continental Southeast Asia), and ''Tragulus javanicus'' (found in Java).<ref name=meijaard6>Meijaard, E., & Groves, C.

==Appearance and biology==
===Geographic range===
''Tragulus javanicus'', by definition, is endemic to Java, [[Indonesia]]. Sightings of ''Tragulus javanicus'' have been reported on the island of [[Bali]], but these reports have not been conclusively researched, thus it is uncertain if a population of Java mouse-deer exist outside of Java on Bali.<ref name="iucn11>Duckworth, J.
