New Cicadomorpha from the Triassic of China raise questions on the systematics of Archijassidae

This is the authors' abstract. We don't add key points for this paper.

The fossil record of Cicadomorpha is fragmentary, and mostly based on isolated tegmina. Here, we describe and illustrate a new genus and species, Triasalus chromatus gen. et sp. nov., from the Middle–Upper Triassic Yanchang Formation of Tongchuan City, northern China. The new specimen exhibits features similar to those of the two early cicadomorphan families, Hylicellidae and Archijassidae, preventing a secure assignment to either group. The classification history of Hylicellidae and Archijassidae is reviewed and the morphological characters currently used to distinguish the two families are discussed.
