记述中蝎蛉科Mesopanorpodidae 4属4种,其中包括3新属4新种:Longifurcula hejiafangensi gen.et sp.nov,Ladinochorista lata gen.et sp.nov.,Allochorista erdosensis gen.et sp.nov.,Itaphlebia tongchuanensis sp.nov..化石标本采自陕西铜川中三叠统铜川组下段上部的灰绿色泥岩和页岩.这些新属、种系陕西昆虫群铜川昆虫组合的新成员(属陕西动物群、陕西生物群的一个类别).根据前人的植物、孢子、双壳、叶肢介、介形虫、昆虫化石等的研究结果,铜川组的时代划归中三叠世,相当于欧洲中三叠世拉丁尼期(Ladinian stage).

Three new genera and four new species: Longifurcula hejiafangensis gen. et sp. nov. Allochorista erdosensis gen. et sp. nov.,Ladindochorista lata gen. et sp. nov., Itaphlebia tongchuanensis sp. nov. (Mesopanorpodidae Tillyard, 1918) are described. The specimens are collected from the Upper part grayish-green mudstone and shale of the Lower Member of the Middle Triassic Tongchuan Formation (Tr2t), Tongchuan Region, Shaanxi Province, China.According to the venational characters, especially Rs and M with 4 branches respectively, these new genera and species should be referred to Mesopanoropodidae and belong to new members of the Tongchuan Entomassemblage of Shaanxi Entomofauna (one group of Shaanxi fauna or Shaanxi Biota). The Tongchuan Formation, bearing insects and other fossils, can be corresponded to European Midtriassic Ladinian stage.
