摘　　要：Apodemus （mice） and Rattus （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 b sequences in GenBank.We also tested whether species could be identified using external and craniodental measurements exclusively.Measurements from 147 specimens of Apodemus and 233 specimens of Rattus were used for morphological comparisons.We analysed 74 cyt b sequences of Apodemus and 100 cyt b sequences of Rattus to facilitate phylogenetic estimations.Results demonstrated that nine species of Apodemus and seven species of Rattus,plus a new subspecies of Rattus nitidus,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 Rattus pyctoris in China remains uncertain.Apodemus （mice） and Rattus （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 b sequences in GenBank.We also tested whether species could be identified using external and craniodental measurements exclusively.Measurements from 147 specimens of Apodemus and 233 specimens of Rattus were used for morphological comparisons.We analysed 74 cyt b sequences of Apodemus and 100 cyt b sequences of Rattus to facilitate phylogenetic estimations.Results demonstrated that nine species of Apodemus and seven species of Rattus,plus a new subspecies of Rattus nitidus,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 Rattus pyctoris in China remains uncertain.
