摘要The Late Miocene witnessed the transition of cricetids from ancient to modernized taxa.Here we describe a new cricetid species, Nannocricetus wuae, from DM02, near the Damiao Village, Siziwangqi, Nei Mongol.The new species is characterized by having low crowned molars with conical shaped cusps, single anteroconid on ml with developed labial and/or lingual flanges, very weak to absent mesolophids on m1, variable mesolophid and very reduced anterolophulid on m2, narrow and slightly bifid anterocone on M1, and relatively long M3.Differing from the pattern of Cricetodontinae, Nannocricetus wuae shows great simplification of tooth structure.There is no paracone spur, anteromesoloph, or styles on upper molars, no spur of anterolophulid or stylids on lower molars.Root numbers are conservative, three for upper molars and two for lower molars.Morphologically, the new species shows close similarity to Nannocricetus primitivus and N.mongolicus.These three species constitute an endemic group confined to North China, and show progressive evolution in the splitting of the anteroconid on m1, reduction of the mesoloph(id), and development of anterolophule(id)on m2/M2 etc. Based on the evolutionary stage of the new species and associated fossils, we tentatively suggest an earliest Late Miocene age pending further confirmation by systematic study of other taxa and the paleomagnetic data.
