Gaoligong in the Yunnan Province, where it lives in subtropical evergreen broad-leaved forest at elevations between 2,200 and 2,680 m (7,220 and 8,790 ft).
This distribution is disjunct from that of the other species in this genus.
M. wangi can be distinguished from other species in the genus by its spine color patterns, the broad nasal region, and the presence of M4 teeth.
It hibernates between mid-October and early April.
While the population size has not yet been quantified, it is likely very small as the species has only been found in the Gaoligongshan National Nature Reserve.
