摘　　要：本文记述了采集自我国辽宁省北票市中生界下白垩统义县组地层的草蛉科篱草蛉亚科原草蛉属一新种,短脉原草蛉。该属此前仅在丹麦和加拿大的新生界地层中发现2种,新种与该属的其它种具有显著差异,如前翅基部第一支r1-rs横脉位于Rs起始处与Rs第一支脉分出处之间,R1在翅端前结束。本文简要对比了原草蛉属与篱草蛉亚科其它属的特征差异,并对新种的归属及其与该属其它种的特征差异进行了讨论。A new species of green lacewings,Protochrysa brevinervis sp.nov.is described from the Early Cretaceous Yixian Formation of Liaoning Province,China.The new species is assigned to the limaiines genus Protochrysa,which were reported only from the Cenozoic of Denmark and Canada before.The new species is distinguished from the other species of Protochrysa by the basal most r1-rs crossvein positioned between the separation of Rs and Rs first branch,R1 ended before wing apex.In this study,Protochrysa is briefly compared with other genera of Limaiinae.The assignment of the new species,as well as its differences from the other species of the genus is discussed.
