Abstract
Paleomydas menatensis gen. et sp. nov., the third known fossil mydid fly, is described from the Paleocene of Menat (France). The fossil fly is remarkable in its very broad hind femur, a rather infrequent character in this family, which is mainly present in the Neotropical genera Mapinguari and Ceriomydas, and to a less pronounced degree, in the Nearctic genus Phyllomydas. But the lack of information on the antenna and genitalia structures forbids us to specify its relationships within the Mydidae more precisely. Thus we propose to attribute it to a new genus. The systematic affiliation of the late Eocene Mydas miocenicus from Florissant is discussed. Because of the rarity of Diptera in the insect assemblage of the Menat outcrop, the present discovery could suggest that this nowadays rather rare family was more frequent during the Paleocene than today.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
