Abstract: Totally 394 specimens of Chardinomys were collected from 3 sections which ranging from latest Miocene to early Pleistocene near Leijiahe Village , Lingtai County , Gansu Province by screen2 washing during 1997～1999 field work seasons. These well stratigraphically calibrated specimens, representing all the forms known in China and 2 new primitive forms of this genus, give an unprecedented chance to revise all the known species and to study systematically the evolutionary relationships of the species in the genus. In addition, the relationships of Chardinomys with Occitanomys and Orientalomys are also discussed in this paper.
