Muntiacus. The exact size of is unknown, but it has been described to be approximately 15 kg by local hunters. It has black fur on its legs and bright orange fur on its head. Dorsal pelage is brown and it has a broad flat tail with black dorsal fur and long white ventral fur which distinguishes it from its similar sized relative, Muntiacus rooseveltorum. It has white rings surrounding each hoof. Similar to other muntjac species, has ridges running from the top of the snout to the apex of the head, which give rise to short, simple, burred antlers that are hidden by tufts of long fur at the top of the head. Like those of many species of Muntiacus, the canines of are long and tusk-like. is the only muntjac species in which females and males have similarly sized canines. No description has been given of juvenile . However, many related cervids, including species in Muntiacus, have young with spotted coats. (Giao, et al., 1998; Macdonald, 2001; Sterling and Hurley, 2006; Vrba, 2000)is one of the smaller members of
The mating system of Muntiacus vaginalis and Muntiacus reevesi, mate year round. Male M. reevesi defend territories that overlap with those of females. Males compete for mates by locking antlers and pushing against each other. They use their tusks to scratch the faces and necks of rival males. Both sexes of M. reevesi are semi-vocal. Males "buzz" when approaching a female in estrus, and receptive females whine and lower their heads to males. (Deuling and Myers, 2004; Timmins, et al., 2008b; Yahner, 1979)is unknown. Other species in the genus, including
Members of Muntiacus living in similar habitats as , such as M. reevesi and M. vaginalis, are polygynous and aseasonal breeders. Gestation is variable in Muntiacus. For example, gestation in Muntiacus muntjak lasts for 180 days, while that of M. reevesi lasts for 210 days. (Barrette, 1977; Deuling and Myers, 2004; Macdonald, 2001; Timmins, et al., 2008b; Yahner, 1979)
There is no information available regarding parental investment in Muntiacus reevesi exhibits minimal parental care and weans offspring at 17 weeks. Like many small cervids in enclosed environments (e.g., forests), likely has young that exhibit hiding behavior in which young lie and hide for extended periods of time, while mothers wander off to graze and then return periodically to nurse. (Deuling and Myers, 2004; Fisher, et al., 2002), but it is probably similar to that of close relatives.
No information was found on the longevity ofin the wild or captivity.
The home range of Muntiacus reevesi is about 108 ha, and have a core area that they use most heavily and actively defend. Overall, range size appears to be independent of topography or resource availability. (McCullough, et al., 2000)is unknown. The average home range of
Many species of Muntiacus are somewhat vocal, but it is not known if is included among them. Males "buzz" when approaching a female in estrus, and receptive females whine and lower their heads to males. Vocal species use barking as an alarm system to warn of potential dangers such as predators. (Yahner, 1980)
Little is known about the diet of munjacs are herbivorous, M. reevesi is known to be omnivorous, eating carrion and small animals. Other species of Muntiacus, such as Muntiacus vaginalis, are generalist herbivores eating a wide range of flora including fruit, twigs, seeds and foliage. (Deuling and Myers, 2004; Macdonald, 2001; Timmins, et al., 2008b). While most
A range of large predators including tigers, leopards, and crocodiles commonly prey upon many muntjacs. Humans are the only confirmed predator of . Potential predatory defense mechanisms of are unknown. (Deuling and Myers, 2004; Giao, et al., 1998; Yahner, 1980)
There are no known adverse effects ofon humans.
Little is known of the potential conservation needs of muntjacs species. As a result, this species is classified as "data defficient" on the IUCN's Red List of Threatened Species. Possible threats include hunting and habitat loss. (Timmins, et al., 2008a; Trimmins and Cuong, 2001), due in part to the difficulty of distinguishing it from closely related
Muntiacus truonsonensis was thought to be the rediscovered Muntiacus rooseveltorum as they share similar appearance. However, genetic tests have revealed that is indeed a unique species. It is one of a number of artiodactyls discovered at the end of the 20th century in the Oriental region. The late discovery is due to a lack of research in the Truong Son Range. This area borders Laos, Vietnam and Cambodia and has a history of warfare and instability. (Mackinnon, 2000; Vrba, 2000)
