Type populations of four fossil species of voles belonging to the genus Mimomys are redescribed. Mimomys ostramosensis is a large-sized, hypsodont Mimomys with enamel islet, Mimomys-ridge and relatively abundant cement. Mimomys tornensis, a medium-sized vole, is characterized by lack of typical Mimomys-ridge and islet present only in M3/, with very abundant cement accumulation. Mimomys pitymyoides, a medium-sized Mimomys, with broadly confluent triangles, is distinguished by the presence of islets and Mimomys-ridge in most specimens relatively low tracts and differentiation of enamel thickness not so distinct as in other Mimomys species. Mimomys pusillus is a small-sized vole with islet present only in younger wear stages, relatively frequent Mimomys-ridge and relatively low tracts.
