The extinct family Locustavidae (Insecta: Orthoptera) is rare in the fossil record, and to date no representative has been reported from China. In this paper, Hejiafanga tongchuanensis gen. et sp. nov. is described based on a single forewing from the Middle Triassic Tongchuan Formation of Shaanxi Province, northwestern China. It is the first orthopteran to be reported from the Triassic of China and the oldest record of Caelifera from East Asia. The discovery expands the global distribution of Locustavidae (stem grasshoppers) and expands knowledge of this rare group during Middle–Late Triassic times.
