Abstract: The discovered fossil glosselytrods in the world are rare, which have been known with only 6 families, 12 genera and 26 species. In this paper the author described three new Midtriassic fossil glosse lytrods belonging to the new members of Tongchuan Entomassemblage of Shaanxi Entomofauna (one fossil group of Shaanxi Biota). Judged on the results of study on the fossils of glosselytrods and other insects, other animals and plants, the geological age of the Tongchuan Formation corresponded to European Latinian stage in age. Based on the characteristics of these insects and other fossils, the author inferred that the Gondwana continent might separate from the Eurasian continent before the Middle Triassic Ladinian stage. Type specimens are deposited in Beijing Museum of Natural History.
