This study presents a study of biting midge (Diptera: Ceratopogonidae) fauna from early Eocene amber of Oise, Paris Basin, France. The fauna comprise eight species, all of them new to science: Eosphaeromias eocenicus Szadziewski, Santer, Nel, & Krzemińska gen. et sp. nov. Leptoconops oisensis Szadziewski, Santer, Nel, & Krzemiński sp. nov., Brachypogon (Isohelea) europaeus Szadziewski, Santer, Nel, & Krzemiński sp. nov.; Brachypogon (Isohelea) oisensis Szadziewski, Santer, Nel, & Krzemiński sp. nov.; Brachypogon (Brachypogon) parisiensis Szadziewski, Santer, Nel, & Krzemiński sp. nov., Stilobezzia (Acanthohelea) eocenica Szadziewski, Santer, Nel, & Krzemiński sp. nov., Forcipomyia oisensis Szadziewski, Santer, Nel, & Krzemiński sp. nov., and Dasyhelea eocenica Szadziewski, Santer, Nel, & Krzemiński sp. nov. The fauna of biting midges from early Eocene Oise forests (53 Ma) shows a low diversity and has no common species with the well-studied middle Eocene fauna of Baltic amber forests (c. 40 Ma).
Key words: Diptera, Ceratopogonidae, new genus, new species, palaeoecology, Ypresian.
