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. 展开更多
