新疆准噶尔盆地中生代陆相地层产有丰富的昆虫化石，已研究报道的计有8属19种，归于4目5科。其中，Protorthophlebia strigata Zhang，1996和Orthophlebia exculpta Zhang，1996产自乌苏上三叠统小泉沟群；Mesohagla xinjiangensis Zhang，1996，Protorthophlebia latipennis Tillyard，1933，Ortlwphlebia latebrosa Sukatsheva,1985，Orthophlebia colorata Zhang，1996，Mesopanorpa brodiei(Tillyard，1933)Martynova，1948，Mesopanorpa kuliki Martynova,1948，Mesopanorpa obscura(Martynov，1925)Martynov，1927，Mesopanorpa densa Zhang，1996，Mesopanorpa monstrosa Zhang，1996，Fletcheriana jurassica Zhang，1997，Plachutella exculpta Zhang，1997和Pseudocossus strenus Zhang，1997产自克拉玛依下侏罗统八道湾组；Ovivagina longa Zhang，1997，Ovivagina propinqua Zhang，1997和Ovivagina prolixa Zhang，1997产自沙湾县八道湾组；Ovivagina immediata Zhang，1997产自克拉玛依中侏罗统西山窑组。根据产自准噶尔盆地下侏罗统的同翅目昆虫盖翅标本，建立3新种，即产自沙湾县南安集海八道湾组的Procercopis shawanensis sp．nov．，产自克拉玛依吐孜沟八道湾组的Procercopina delicata sp．nov．，以及产自吉木萨尔县西大沟三工河组的Eofulgoridium tenellum sp．nov．。前两种归入原沫蝉科，最后一种归入短足蜡蝉科；这是Procercopis Martynov和Procercopina Martynov在中国的首次记录。Procercopis shawanensis与P．longipennis Becker Migdisova相似，区别在于新种R脉近末端有一短分支，Rs脉分叉一次，Rs与M脉之间只有一条横脉；Procsrcopina delicata与P．asiatica Martynov的区别在于新种横脉r-rs和r-m没有在一条线上，Rs脉分为2支，M脉后支简单；Eofulgoridium tenellum与E．kisylkiense Martynov的区别在于后者Sc脉在C脉与R脉的中间，M脉三分支。CuA脉在R脉主干分为R与Rs脉之前分叉。

Three new species are described herein based on tegmina from the Lower Jurassic of the Junggar Basin in Xinjiang, China. They are Procercopis shawanensis sp. nov. (from the Badaowan Formation of Shawan County), Procercopina delicata sp. nov. (from the Badaowan Formation of Karamay City) and Eofulgoridium tenellum sp. nov.
