Seven new rodent faunas are described from the Pčinja and Babušnica-Koritnica basins of south-east Serbia. The geology of the Tertiary deposits in the Pčinja and Koritnica-Babušnica basins of south-east Serbia is briefly reviewed. The fossil content of the new vertebrate localities is listed, and an inventory of the rodent associations is presented. The rodent associations are late Eocene-early Oligocene in age, interpreted on biostratigraphical grounds. These are the first rodent faunas of that age from the Balkan area, an important palaeogeographic location between Europe and Asia. The Muridae, with the subfamilies Pseudocricetodontinae, Paracricetodontinae, Pappocricetodontinae, Melissiodontinae and ?Spalacinae, are dominant with eight genera, four of which are new. The diversity of the Melissiodontinae and Paracricetodontinae in the faunas suggests that these subfamilies originated in this region. The bi-lophodont cheek teeth occurring in the Oligocene assemblages are identified as the first record of the Diatomyidae outside of Asia. In light of the large amount of new data, the palaeogeographic setting and faunal turnover of the Eocene-Oligocene is discussed.

来自塞尔维亚东南部古近代的啮齿动物群。

从塞尔维亚东南部的Pčinja和Babušnica-Koritnica盆地描述了7种新的啮齿动物。简要回顾了塞尔维亚东南部Pčinja和Koritnica-Babušnica盆地第三纪沉积的地质情况。列出了新脊椎动物地区的化石含量，并列出了啮齿动物协会的清单。啮齿类动物的年龄是始新世晚期至渐新世晚期，以生物地层学为依据。这些是巴尔干地区那个年代的第一个啮齿动物区系，巴尔干地区是欧洲和亚洲之间的重要古地理位置。鼠科具有假cri科，副cri科，P科，齿don科和Spa科，有八个属，其中四个是新科。动物区系中的Melissiodontinae和Paracricetodontinae的多样性表明，这些亚科起源于该地区。在渐新世组合中出现的双牙周颊齿被认为是亚洲以外的硅藻科的第一记录。鉴于大量的新数据，讨论了始新世-渐新世的古地理环境和动物区系更新。
