It ranges from northeastern India north to southern China and south to northern Myanmar. An isolated population (not considered part of M. montivagus by the American Society of Mammalogists) is known from Laos and Vietnam. It is thought to inhabit tropical montane forest for most of its range, although in Vietnam it is also known from lowland habitats, including agricultural fields.
Very little information is known about this species, and it is thus classified as Data Deficient on the IUCN Red List. It may be threatened by the loss or degradation of cave and forest habitats.
