The Gongshan-muntjac ( Muntiacus gongshanensis ) is a kind of barking from the family of deer . It occurs only in a small part of the Chinese province of Yunnan and the neighboring Myanmar .
features
The head-trunk length of the Gongshan muntjak is 95 to 105 centimeters, the tail length 9 to 16 centimeters. The shoulder height is 55 to 57 centimeters. The weight of the individual animals is 17–40 kilograms. The animals are medium-sized with long, slender legs. They have a dark red-brown fur and an orange-brown color on the head. They correspond to the black muntjak ( Muntiacus crinifrons ), but differ from it in the slightly lighter color, the smaller size and the shorter tail as well as the longer hooves. In addition, the roots of the antlers are short and thick and they have no noticeable tufts of hair. This species has a white ring on its feet.

The skull has a total length of 190 to 205 millimeters. Like all muntjac has the kind maxillary per half a canine (canine), three Vorbackenzähne (Praemolares) and three molars (molars), incisors are missing. In the lower jaw, it has three additional incisors in each half. The animals have a total of 34 teeth.
Genetic traits
The genome of the Gongshan muntjak consists of a very small number of chromosomes : the males have a diploid chromosome set of 2n = 9 chromosomes, while the females have 2n = 8. For comparison, the Chinese muntjac has 2n = 46 chromosomes.
distribution
The Gongshan muntjac occurs only in a small part in the far northwest of the Chinese province of Yunnan and the neighboring northern Myanmar .
Way of life
No data are available on the way of life of the Gongshan muntjac, but it is assumed that it corresponds to that of other muntjacs and especially the black muntjac.
Systematics
The Gongshan muntjac is classified as an independent species within the Muntjaks (genus Muntiacus ), which consists of eleven species. The first scientific description comes from Shilay Ma from 1990, who described the species from Puladi municipality in Gongshan County in Yunnan Province and named it after its origin. Apart from the nominate form Muntiacus gongshanensis gongshanensis, no further subspecies are distinguished within the species .
There is uncertainty about the taxonomic classification and species status. The Gongshan muntjac has already been assigned to the Chinese muntjac ( Muntiacus reevesi ), the Indian muntjak ( Muntiacus muntjak ) and the tenasserim muntjac ( Muntiacus feae ). More recent studies determine a very close relationship with the black muntjak ( Muntiacus crinifrons ) and assign Muntiacus gongshanensis as a synonym of this species.
Hazard and protection
The species is not classified in a hazard category by the International Union for Conservation of Nature and Natural Resources (IUCN) due to the very uncertain data on its systematics and allocation and thus on the stocks, but rather marked with "data deficient".
