New Triassic Hylicellidae from northern China (Hemiptera, Cicadomorpha).

A new genus and species of the extinct cicadomorphan family Hylicellidae, Vetusala maculata gen. et sp. nov., is described and illustrated based on a forewing specimen from the Middle-Upper Triassic Yanchang Formation of northern China. The new discovery represents the earliest and the first definite Triassic member of Hylicellidae in China, further shedding light on the diversity of cicadomorphan insects in the Tongchuan entomofauna.
