摘要
A new genus and species, Longucercopis xinjiangensis gen. et sp. nov., is established and assigned to the froghopper family Procercopidae based on a well-preserved tegmen from the Lower Jurassic Sangonghe Formation in Haojiagou Toutunhe section, Urumqi, Xinjiang, NW China. The new taxon is unique in having a slender tegmen (length/width near 4.0:1) with narrow appendix, crossvein mp-cua,connected to vein MP much basal of rp-mp and ir, and cua-cup long. A key to genera of Procercopidae is provided, and the phylogenetic position of Longucercopis gen. nov. in Procercopidae is also discussed.
