摘要
描述的昆虫化石产自辽西朝阳县大平房乡原家洼九佛堂组。该化石为一新种,命名为原家洼始长腹细蜂(Eopelecinusyuanjiawaensissp.nov.),归入长腹细蜂科(Pelecinidae)。该科是昆虫纲膜翅目中一个现生小科,仅包括1属3种,分布在美洲大陆。该科在白垩纪曾广泛分布于欧亚大陆,在我国曾发现于辽西的义县组和山东的莱阳组中。
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.
