A STUDY OF THE SUBSPECIES CLASSIFICATION OF APODEMUS AGRARIUS IN EASTERN CONTINENTAL CHINA

This paper describes the morphological difference of A, agrarius from different areas in eastern continental China. The author suggests that A. agrarius can be divided into two subspecies after the comparison of the clearness of the black dorsal stripe and the colour of their dorsal hair. The two subspecies are: A. a. manchuricus and A. a. ningpoensis. A previously claimed subspecies -A.a.pallidior shows no distinctive feature over the classification. Samples of A.a.pallidior taken from north of Qinling Mountains to the Huai River line have very similar dorsal coloration and black stripe with that of A,a.manchuricus, while samples taken from south of the above line have very similar dorsal coloration and black stripe with that of A. a. ningpoensis. The distribution of A. a. manchuricius and A. a, ningpoensis is demarcated along the Qinling Mountains to Huai River line which is also the eastern boundary of the Palacarctic Realm and Oriental Realm in China's animal geographic division.
