(mice) and (rats) are the top rodent reservoirs for zoonoses in China, yet little is known about their diversity. We reexamined the alpha diversity of these two genera based on a new collection of specimens from China and their cyt sequences in GenBank. We also tested whether species could be identified using external and craniodental measurements exclusively. Measurements from 147 specimens of and 236 specimens of Rattus were used for morphological comparisons. We analysed 74 cyt sequences of Apodemus and 100 cyt sequences of to facilitate phylogenetic estimations. Results demonstrated that nine species of and seven species of , plus a new subspecies of , are distributed in China. Principal component analysis using external and craniodental measurements revealed that measurements alone could not separate the recognized species. The occurrence of in China remains uncertain.
在中国，（鼠）和（大鼠）是最重要的人畜共患病的啮齿动物储存宿主，但对它们的多样性知之甚少。我们根据从中国新收集的标本和 GenBank 中的细胞序列，重新检查了这两个属的α多样性。我们还测试了仅使用外部和颅面测量值是否可以识别物种。对 147 个 标本和 236 个 Rattus 标本的测量值用于形态比较。我们分析了 74 个 Apodemus 的细胞序列和 100 个 的细胞序列，以促进系统发育估计。结果表明，在中国分布着九种 和七种 ，以及一个新的亚种 。使用外部和颅面测量值的主成分分析表明，仅通过测量值无法分离出已识别的物种。在中国 的发生仍然不确定。
