A new procercopid froghopper (Hemiptera: Cicadomorpha: Procercopidae) from the Lower Cretaceous Jiufotang Formation, western Liaoning Province, NE China.

A new procercopid species <italic>Stellularis kazuoensis</italic> sp. nov. is established and described from the Lower Cretaceous Jiufotang Formation in the Kazuo Basin, western Liaoning Province, NE China. It is characterised by the tegmen with singular RA, RP and M veins; vein M+CuA about half length of vein R; vein RA curved in apical area; and crossvein <italic>m-cua</italic> apicad of CuA2 end but basad of <italic>ir</italic> and <italic>r-m</italic>. The new species not only increases the diversity of Procercopidae but also provides more tegminal information of the genus <italic>Stellularis</italic>. The venational distinctions on tegmen between <italic>S. kazuoensis</italic> sp. nov. and the other species of <italic>Stellularis</italic> are schematically shown and discussed. The record of fossil insects from the Jiufotang Formation is also summarised. [ABSTRACT FROM AUTHOR]
