本文根据一枚产自华中地区豫西济源盆地谭庄组上段的昆虫化石标本建立1新属新种——济源三叠幻蝉(Triasomaguviopsis jiyuanensis Zhang Q. et Zhang H. gen. et sp. nov.), 归入原蝉总科幻蝉科(半翅目, 蝉亚目)。本新类群以盖翅较小且具瘤、ScP+RA在盖翅中部初次分支、MP脉三分支且初次分支水平处晚于ScP+RA脉、CuA脉弯曲无分支为特征。幻蝉科的古地理分布范围扩展至济源盆地，该科分异度增加并具备生物地层对比潜力。谭庄组的昆虫化石可归入鄂尔多斯盆地的“铜川昆虫群”, 并且“铜川昆虫群”与吉尔吉斯斯坦的“Madygen昆虫群”关系密切。

A new fossil insect taxon, Triasomaguviopsis jiyuanensis Zhang Q. et Zhang H. gen. et sp. nov., is established based on a specimen from the Upper Member of the Tanzhuang Formation, Jiyuan Basin, western Henan Province, central China, and is assigned to the family Maguviopseidae of the superfamily Prosboloidea (Hemiptera, Cica- domorpha). This new taxon ischaracterized by smaller granular tegmen, ScP+RA first forked near its mid-length, MP forked more toward apex of ScP+R with three terminals, and singular and sinuous CuA₂. This new discovery extends the palaeogeographic distribution of Maguviopseidae to the Jiyuan Basin, increases diversity of this family and has the potential in biostratigraphic correlations. Insects from the Tanzhuang Formation may belong to the Tongchuan Entomofauna from the Ordos Basin, which has a close relationship with the Madygen Entomofauna from Kyrgyzstan.
