Oligaeschna sinica sp. nov., the oldest recorded and first Chinese representative of the Cenozoic aeshnid genus Oligaeschna, is described from the Bartonian of Tibet. This fossil is also among the oldest known representatives of the family Aeshnidae sensu stricto. Its presence in the Niubao Formation supports a temperate, cool to warm climate for the area during this period.
