【Abstract】 A new wasp, Eopelecinus yuanjiawaensis sp. nov., is described from the Lower Cretaceous Jiufotang Formation of the Yuanjiawa locality, Dapingfang, Chaoyang, western Liaoning and assigned to the family Pelecinidae (Insecta, Hymenoptera, Proctotrupoidea). Besides insects, many vertebrates including pterosaurs, dinosaurs and birds have been discovered from the same horizon in this area. Although comprising only three extant species confined to America, the Pelecinidae were widely distributed in Eurasia in the Cretaceous. In China, they have been found from the Yixian Formation in western Liaoning and Laiyang Formation in Shandong.更多还原
