Abstract

An impression fossil of an eremochaetid fly from Lower Cretaceous Laiyang Formation is described and a new genus and species is proposed: Guamaimengia laiyangensis gen. et sp. nov. The evolution of wing venation in Eremochaetidae is discussed. The relationships between Eremochaetidae and Archisargidae are reviewed and reassessed: they are not only sister groups but probably play a role in the species-abundant checks and balances at one and the same locality. The conclusion of competitive mechanisms between extinct groups is proposed.

期刊介绍： Cretaceous Research provides a forum for the rapid publication of research on all aspects of the Cretaceous Period, including its boundaries with the Jurassic and Palaeogene. Authoritative papers reporting detailed investigations of Cretaceous stratigraphy and palaeontology, studies of regional geology, and reviews of recently published books are complemented by short communications of significant new findings. Papers submitted to Cretaceous Research should place the research in a broad context, with emphasis placed towards our better understanding of the Cretaceous, that are therefore of interest to the diverse, international readership of the journal. Full length papers that focus solely on a local theme or area will not be accepted for publication; authors of short communications are encouraged to discuss how their findings are of relevance to the Cretaceous on a broad scale. Research Areas include: • Regional geology • Stratigraphy and palaeontology • Palaeobiology • Palaeobiogeography • Palaeoceanography • Palaeoclimatology • Evolutionary Palaeoecology • Geochronology • Global events.
