A new genus and two new species of the family Eomyidae, Megapeomys lavocati and M. lindsayi, from the North Bohemian brown coal basins and South German karstic sites, are described. The new genus Megapeomys is also reported from the Early Miocene of Japan, which suggests a wide paleogeographic distribution and implies a successful but short lasting adaptation in an unknown and until now rarely recorded habitat. The entire history of the Late Oligocene-Early Miocene Apeomys-Megapeomys group in the Old World is with recognition of a new subfamily of eomyids, Apeomyinae subfam. nov. Comparisons with other rodents that resemble apeomyines in having bilobed teeth suggest that the bilophodonty in this group arose independently.
