摘　　要：研究了鼢鼠属Ｅｏｓｐａｌａｘ亚属的分类及其系统演化．根据大量标本的研究，本亚属应包含６个种：中华鼢鼠（Ｍｙｏｓｐａｌａｘｆｏｎｔａｎｉｅｒｉ）、甘肃鼢鼠（Ｍ．ｃａｎｓｕｓ）、罗氏鼢鼠（Ｍ．ｒｏｔｈｓｃｈｉｌｄｉ）、高原鼢鼠（Ｍ．ｂａｉｌｅｙｉ）、斯氏鼢鼠（Ｍ．ｓｍｉｔｈｉ）以及秦岭鼢鼠（Ｍ．ｒｕｆｅｓｃｅｎｓ）．通过化石、地质资料以及现生种特征的对比分析，初步建立了鼢鼠属Ｍｙｏｓｐａｌａｘ的系统演化树，并认为该属中Ｅｏｓｐａｌａｘ亚属的发生中心在华北地区。Taxonomy and phylogeny of subgenus Eospalax which belongs to genus Myospalax are studied. After studying on a large number of zokor specimens which are collected from different districts, it is found that there are six species in the subgenus Eospalax. They are Chinese zokor(M.fontanieri), Gansu zokor(M,cansus), Bailey′s zokor(M,baileyi), Rothschild′s zokor(M.rothschildi), Smith′s zokor(M.smithi) and Rufescent zokor (M.rufescens). On the basis of studying of fossil zokor and geological data as well as comparison between different species, the evolutionary tree of the genus Myospalaz is tentatively established. The study results also indicate that the occurring center of the subgenus Eospalax is in North China, while the evolutionary center is in inner Qinling Mountain.
