Abstract
The Fannia posticata species-group was established by Chillcott in 1961. Sixteen species of this group are known worldwide. A new species, F. davidianicornis, sp. nov. is described from China and five Palaearctic species of the group are reviewed. A diagnosis and a key to the 5 known Palaearctic species is presented. The type specimens are deposited in the Institute of Entomology, Shenyang Normal University.
