A complete and well-preserved forewing assigned to the orthopteran insect Parahagla cheni Xu, Fang and Zhang, 2023 is described from the Lower Jurassic Badaowan Formation of the northwestern Junggar Basin (Karamay, Xinjiang, northwestern China), based on which the species is diagnostically revised. It represents the earliest record of the subfamily Chifengiinae under the family Prophalangopsidae. The subfamily Chifengiinae is reviewed and a key to its genera and species is provided in the discussion. A further discuss of the palaeobiogeographic distribution of Chifengiinae shows that the subfamily probably first appeared in the Palaeoarctic in the earliest Jurassic, and later quickly migrated and occupied most areas of eastern Palaeoarctic from the Middle Jurassic to the Early Cretaceous.
