Laiyangella zhangi gen. et sp. nov., the first grasshopper from the Lower Laiyang Formation in Shandong Province, China, is described. Although it exhibits cixioid venation that would suggest its placement with or near Cixiidae, the well-preserved genitalic impression of this female specimen is not orthopteroid but fulgoroid. Laiyangella gen. nov. is thus placed in a sister position to the base of the fulgoroid lineage in the Fulgoroidea, it represents the oldest fossil of that lineage. Laiyangella gen. nov. appears to be a key taxon for better understanding the early evolution of Fulgoroidea. It warns us of the weakness of the taxonomic diagnoses currently used to identify major groups that need to be reevaluated.
