This paper reports a new species of the genus Muntiacus, according to 1 old adult male, 1 younger adult female, 1 infancy female and 3 skins collected from Gaoligong and Biluo Mountain, north-western Yunnan China. The type specimens and examined specimens are deposited in Kunming Institute of Zoology, Academia Sinica, Kunming. We record it as follows:
Muntiacus gongshanensis Ma, sp. nov.
Holotype : KIZ 880018, An old adult male, collected in March, 1988, from Mijiao (27°35' N., 98°47' E. ) , Puladi, Gongshan county, East slope of the northern sector of Gaoligong Mountain, north-western Yunnan.
Paratype: KIZ 890003, a younger adult female (with 1(?) foetus), collected in April, 1989, from Fugong county, west slope of the Gaoligong Mountain (elevation 3000 metres).
Examined specimens: 1 infancy female, KIZ 890002, from Fugong cou-nly, W. Yunnan) 3 adult skins (KIZ 7331) KIZ 74410 and KIZ 83001), purchased in the period 1973 to 1983, all from Gaoligong and Diluo Mou- ntain, W. Yunnan.
Diagnosis: Body medium size, weight 16-24kg, body length 950-1045 mm, the greatest skull length 194.8-205.4mm, without the tuft on the forehead, with non-obviously frontal glands and rather small chin glands ((?)17×12mm, (?)×9mm). The antler (71.7mm) is distinctly longer than the antler pedicel (34.5mm). The colour of the back of tail is dark-brownish, similar in tone to the back of body. The condylo-lateral processus (Fig. 1, D-e) is obviously larger than that of other species of the genus Muntiacus,
Remarks :The new species, Gongshan's muntjac (Muntiacus gongshane-nsis), is little similar to M. crinifrons, M. feai and M. rooseveltorum in colour of body, but it has no the tuft on forehead, and the lacrymal separate completly with nasal. The tone of the back of tail is not as dark as adovc mentioned 3 species. M. gongshanensis, in body and hoof size, is obviously larger than M. rccvesi. It differs from M. muntjak in that the larger lacrymal pit and no lacrymal projection extending to nasal except the body dark brown. Also, the chromosomes of the new species ( 2n = 9(?), 8(?) is same as M. crinifrons, not as the other 4 species of Muntiacus. However, according to Shi Liming and Ma Caixia (1988), the Ag-NORs sites between the new species and M. crinifrons are with .some differences (Table 3 ). Phylogenetic status of the new species in the genus Muntiacus, based on the morphological characterize and the karyotypical structure, seems to be between M, crinifrons and M. feai.
