东方田鼠的分类学研究至今仍存在争议。在这项研究中，我们探讨了所有物种的东方田鼠，除了Eothenomys wardi，使用DNA序列和形态数据相结合的系统学。我们的分子遗传学，基于两个线粒体基因（COI和cyt B），解决了东方田鼠作为一个单系群的强有力的支持。四个不同的谱系被解决：Eothenomys，Anteliomys，Caryomys，和新的亚属Ermites。根据形态学特征，我们认为核鼠属和绒鼠属是有效的属。Eothenomys，Anteliomys和Ermites是Eothenomys的亚属。分子系统发育将Anteliomys亚属和Ermites亚属视为姐妹分类群。Eothenomys亚属是Anteliomys + Ermites分支的姐妹。Caryomys是Eothenomys属的姐妹群。此外，亚种E. custus hintoni和E. chinensis tarquinius与E. custus custus和E. chinensis chinensis，将前两个分类群提升到种的水平，归属于Ermites新亚属。
The systematics of Oriental voles remains controversial despite numerous previous studies. In this study, we explore the systematics of all species of Oriental voles, except Eothenomys wardi, using a combination of DNA sequences and morphological data. Our molecular phylogeny, based on two mitochondrial genes (COI and cyt b), resolves the Oriental voles as a monophyletic group with strong support. Four distinct lineages are resolved: Eothenomys, Anteliomys, Caryomys, and the new subgenus Ermites. Based on morphology, we consider Caryomys and Eothenomys to be valid genera. Eothenomys, Anteliomys, and Ermites are subgenera of Eothenomys. The molecular phylogeny resolves subgenera Anteliomys and Ermites as sister taxa. Subgenus Eothenomys is sister to the clade Anteliomys + Ermites. Caryomys is the sister group to genus Eothenomys. Further, the subspecies E. custos hintoni and E. chinensis tarquinius do not cluster with E. custos custos and E. chinensis chinensis, respectively, and the former two taxa are elevated to species level and assigned to the new subgenus Ermites.
