This small cricetid rodent is recorded around Baicaopo Nature Reserve in Jinyang County, Liangshan, Sichuan, China. Its reported habitat is moist grassland above 3,000 m, with scattered fir and grass growing to about 1.5 m.
Head-and-body length averages 92 mm; hind feet are under 19 mm, and the tail is about half the head-and-body length. The back is gray, with 10–12 mm fur that is blackish gray at the base and gray at the tips. Some specimens show a faint yellow or yellow-brown tint. The underside is lighter, with hairs blackish gray at the base and gray-white at the tips, so the boundary between back and belly is not sharp. The ears project slightly above the fur, and the tail is gray above and yellow-white below.
