New ephialtitid wasps (Hymenoptera) of the Early Cretaceous Jehol Biota from NE China

The Jurassic-Early Cretaceous family Ephialtitidae is considered as one of the most basal lineages of Apocrita, one of two suborders of the insect order Hymenoptera. Herein three genera and three species, of which one genus and three species are recognized as new to science, are described and illustrated from the Jianshangou Bed of the lower Yixian Formation of western Liaoning, NE China, including Tuphephialtites wangi sp. nov., Crephanogaster beipiaoensis sp. nov., and Chorephialtites longispinus gen. et sp. nov. So far a total of three genera and five species within the subfamily Ephialtitinae are known from the middle Jehol Biota in NE China, suggesting a high morphological disparity of Ephialtitidae during the Early Cretaceous in NE China. Occurrence of Crephanogaster Rasnitsyn, 1990 in both the Turga Formation of Transbaikalia, Russia and the Yixian Formation of NE China confirms these two formations are of coeval deposits. Additionally, a key to the genera of Ephialtitinae is given.

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.
