Abstract

A new genus and two new species of Eremoneura are described from mid-Cretaceous amber of the Charentes region, in south-western France. Chimeromyia vulloi sp. nov., from early Cenomanian amber of Fouras, is the first record of Chimeromyiidae from France. It extends the geographical distribution of this family, which was hitherto known only from Cretaceous ambers of Lebanon, Spain, and Myanmar. A key to all known species of Chimeromyia is provided. Additionally, a specimen from latest Albian–earliest Cenomanian amber from Archingeay, which was studied using synchrotron imaging, is described as Francomyina incomparabilis gen. et sp. nov., and is left unassigned to family within Eremoneura. The affinities of both new species are discussed.
