Two new late Oligocene species of Deperetomys: D. calefactus and D. saltensis, are described and the affinities between the various species are discussed. The new records extend the stratigraphic range of Deperetomys into the Oligocene, making it the first European Miocene murid that can be traced across the “Cricetid vacuum”. A single M1 of a large early Oligocene murid that may represent the oldest record of Deperetomys is described. The classification problems that arise as a result of the fast increase of information of the Paleogene Muridae from Asia and the Middle East are addressed and the need to recognise and define clades above the genus level is demonstrated. Our conclusion is that the Deperetomys clade contains at least three different evolutionary lineages.

两个新的渐新世晚期品种Deperetomys：D. calefactus和D. saltensis，描述并讨论了不同物种之间的亲缘关系。新的记录将Deperetomys的地层范围扩展到渐新世，使其成为第一个可以在“死绝地狱的真空”中追踪的欧洲中新世杂种。描述了大的渐新世早期杂种的单个M1，它可能代表了Deperetomys的最古老记录。解决了由于来自亚洲和中东的古近代鼠科信息的快速增加而产生的分类问题，并证明了识别和定义属以上级别的进化枝的需​​求。我们的结论是Deperetomys进化枝包含至少三个不同的进化谱系。
