China has 26 species in the tribe Arvicolini. The taxonomic status of these voles remains controversial despite much effort. Herein, we evaluate the taxonomic position of 22 species plus 2 unidentified taxa using mitochondrial DNA gene sequences (). We also evaluate 18 species and 2 unidentified taxa using morphological data. Phylogenetic analyses of resolve monophyly for the genera , , , , , and with strong support. clusters with but with very weak support. Analyses of concatenated resolve the same genera with strong support, but the topology of the tree differs from that of in that roots at the base of the tree independent of , which forms the sister-group of in a more terminal position. The matrilineal genealogy excludes the type species from the rest of the Arvicolini. This species forms the sister-group of with high support. includes , , , , , , and 2 unidentified specimens. includes the former species , , , , and . Finally, has the subgenera , s, , , , and , which includes the Chinese species , , and . General mixed Yule-coalescent species delimitation modeling demarcates 6 currently recognized species and 2 new species of . A principal component analysis of the morphological data among 7 matrilines shows that all variables have positive loadings of high magnitude on the 1st component. Canonical discriminant analysis for (including and 2 unidentified species) correctly classifies 93.0% of specimens. Overall, our analyses support the recognition of , , , , , and as genera. includes , and the genealogical position of remains uncertain. The status of requires further study. We assign to and describe 2 new species of .
中国田鼠族（Arvicolini）有26个物种。尽管经过大量研究，但这些田鼠的分类地位仍存在争议。在此，我们使用线粒体DNA基因序列评估了22个物种以及2个未鉴定分类单元的分类地位。我们还使用形态学数据评估了18个物种和2个未鉴定分类单元。对……的系统发育分析有力支持了……属、……属、……属、……属、……属和……属的单系性。……与……聚类，但支持度非常低。对串联……的分析有力支持了相同的属，但树的拓扑结构与……不同，因为……在树的基部独立于……生根，而……在更末端的位置形成……的姐妹群。母系谱系将模式种……与田鼠族的其他物种区分开来。该物种以高支持度形成……的姐妹群。……包括……、……、……、……、……、……以及2个未鉴定标本。……包括原物种……、……、……、……和……。最后，……有亚属……、……、……、……、……和……，其中包括中国物种……、……和……。通用混合尤尔-凝聚物种界定模型划分出6个目前已被认可的……物种和2个新的……物种。对7个母系的形态学数据进行主成分分析表明，所有变量在第一成分上都有高幅度的正负荷。对……（包括……和2个未鉴定物种）的典型判别分析正确分类了93.0%的标本。总体而言，我们的分析支持将……、……、……、……、……和……认可为属。……包括……，而……的谱系位置仍不确定。……的地位需要进一步研究。我们将……归入……并描述了2个新的……物种。
