Its distribution area is in central China and includes the southeast of Gansu , the south of Shanxi , Chongqing , the west of Hubei , the east of Sichuan and the north of Guizhou . The form was introduced in 1996 on the basis of animals from Jingfu Mountain in southern Sichuan as a subspecies of the Chinese dwarf bilk ( Typhlomys cinereus ); it was only given species status in 2017.
