Isolated teeth of Melissiodontinae from two Eocene and four Oligocene localities in southeastern Serbia are described. One new genus and two new species are named. The study of the derived morphology of the cheek teeth and of the contrastingly primordial microstructure of the tooth enamel of this diverse material provides a glimpse into the early history of the subfamily. The supposedly Asian murid ancestor of the Melissiodontinae seems to have reached the Serbian-Macedonian land area during the early or middle Eocene, which is shortly after the split up of the Muridae and Dipodidae and before the ‘Grande Coupure’ of central and Western Europe. We interpret the rapid consequent specialisation of the morphology of the chewing apparatus of the Melissiodontinae as an adaptation to feeding on small invertebrates on the floor of the Eocene forest.

来自塞尔维亚东南部古近纪的新 Melissiodontinae（哺乳纲，啮齿目）。

描述了来自塞尔维亚东南部两个始新世和四个渐新世地点的蜂花科孤立的牙齿。命名了一个新属和两个新种。对颊齿的衍生形态和这种不同材料的牙釉质的原始微观结构的研究提供了对该亚科早期历史的一瞥。据称，Melissiodontinae的亚洲鼠科祖先似乎在始新世早期或中期到达了塞尔维亚-马其顿陆地地区，即鼠科和双足科分裂之后不久，中欧和西欧的“Grande Coupure”之前。我们将蜂花科咀嚼器形态的快速专业化解释为对始新世森林地面小型无脊椎动物的适应。
