This species occurs widely in the Russian Federation (Siberia and the Far East), extreme eastern Kazakhstan, northeastern and northwestern China, Mongolia, Republic of Korea and Democratic People's Republic of Korea (Tsendjav, 2002). Records from Afghanistan, Pakistan, India, Kyrgyzstan, Nepal, Bhutan, Myanmar and Viet Nam refer to other species in the genus Moschus. Four subspecies occur in Russia: M. m. moschiferus (Siberia); M. m. turovi (Russian Far East); M. m. arcticus (Verkhoyansk Ridge); and M. m. sachalinensis (Sakhalin Island). In Mongolia, M. m. moschiferus is found regionally in the forested habitats in the northern Mongol Altai mountain range (Togtokhbayar et al., 2000), Hangai mountain range (Sosorburam, 1970; Dulamtseren, 1977; Dulamtseren et al., 1989), Hentii and Hövsgöl mountain ranges, and possibly around Han Höhii Mountain in the western Hangai mountain range (Dulamtseren et al., 1989; Wemmer, 1998; Tsendjav, 2002). Two subspecies are found in China: M. m. moschiferus in Xinjiang (Altai mountains), Nei Mongol, and Heilongjiang; and M. m. parvipes along the border with North Korea in the Lesser Xing’an and Changbai mountain ranges, as far west as Ordos Plateau. M. m. parvipes occurs widely in both North and South Korea.
