  摘要:根据头骨上间顶骨存在与否、枕盾形状和位置、臼齿带牙根与否以及带牙根臼齿的高冠程度等,将Myospalacinae分成29属。记述了甘肃秦安董湾剖面中的3种原鼢鼠:Prosiphneus licenti Teilhard de Chardin, 1926, P. tianzuensis (Zheng & Li, 1982)P. eriksoni (Schlosser, 1924); 1种上新鼢鼠:Pliosiphneus cf. Pl. lyratus (Teihard de Chardin, 1942); 3种日进鼢鼠:Chardina sinensis (Teilhard de Chardin & Young, 1931), C. gansuensis n. sp.C. truncatus (Teilhard de Chardin, 1942); 3种中鼢鼠:Mesosiphneus primitivus sp. nov., M.praetingi (Teilhard de Chardin, 1942)M. intermedius (Teilhard de Chardin & Young, 1931)。修订了原鼢鼠属(Prosiphneus)、上新鼢鼠属(Pliosiphneus)、日进鼢鼠属(Chardina)和中鼢鼠属(Mesosiphneus)的属征。根据古地磁年代记录,探讨了Pr. eriksoni→Pliosiphneus cf. Pl.lyratus, Pr. eriksoni→C. sinensis, C. gansuensis→M. primitivus之间的进化关系。
