摘要(Abstract):

<正> 姬鼠属(Apodemus)在我国分布广,种类多,与人类的关系密切,不仅是农林区的主要害兽,并且还是一些自然疫源性疾病的主要传染源。近些年来我们在云南、贵州及四川三省1/3以上的县市作了大量的调查,根据这些调查资料,本文特对高山姬鼠(Apodemus chevrieri Milne-Edwards,1868-74)的分类地位进行讨论,并将其与黑线姬鼠(Apodemus agrarius Pallas,1771)加以比较。
This study deals with geographical distribution and morphological chara- cteristics, particularly the glans penis, of Apodemus chevrieri and two subspe- cies of Apodemus agrarius. Based on our studies of a series of speciemens collected from various localities in Southwestern China, we found that A. a. pallidior distributes mainly westwards of the Jailing River and A. a. ningpoensis inhabites mainly eastwards of the same River, but the two subspecies overlaps narrowly along the region of the river. A. chevrieri is found abundantly in the wooded parts of the highland in Yunnan and also in Sichuan and Guizhou at 1,000 - 2,500 m. altitudes. The northeastern and the southeastern part of distributional range of A. chevriei extend deeply into and overlaps the distributional ranges of the two subspecies of A. agrarius. No intermediate forms connecting A. chevrieri and A. agrarius were found. A. a. pallidior has a narrow and fairly well-defined black Mid-dorsal stripe stretching from shoulder to rump. The majority of A. a. ningpoensis has a poorly marked or nearly obsolete dorsal stripe, while in A. chevrieri this is entirely lacking. In average, A. chevrieri is decidedly larger. There are also differences in the structure of the glans penis among the three taxa. The median portion of the basal bone of the glans penis of A. a. ningpoensis is uniformly narrow without an enlargement; that of A. a. pallidior is slightly enlarged in the middle; while that of A. chevrieri is sign- ificantly so. In A. chevrieri, the tripartite lobes of the terminal portion of the papilla lingualis are equal in size and with pointed tips, in A. a. ningpoensis the median lobe is very short and small, while in A. a. pallidior the median is noticably long and larger and takes a round end. In view of the significant differences of the structure of the glans penis between A. chevrieri and the two subspecies of A. agrarius and the characteristics of distributional ranges of these species and subspecies, we hold that A. chevrieri should be withdrawn from the species A. agrarius to restore its specific rank.
