title: Revision on Palaearctic species of Periclistus Förster with description of a new species and its host plant gall (Hymenoptera, Cynipidae).
abstract: Palaearctic species of Periclistus Förster has been systematically described, but a new inquiline gall-wasp, Periclistus qinghainensis sp. n., is described from China. This species was obtained from an unknown stem gall induced on Rosa sp. Diagnosis, distribution and biology of the new species are described in this paper. After examining the types of Periclistus idoneus Belizin, 1973 and Periclistus capillatus Belizin, 1968, it is concluded that Periclistus idoneus belongs to genus Aulacidea, and Periclistus capillatus is a valid species of Periclistus. A key to the Palaearctic Periclistus species is also given.
