Review of the species of Gugolzia Delucchi and Steffan (Hymenoptera: Pteromalidae) in Europe and Turkey, with descriptions of new species

The species of Gugolzia (Hymenoptera: Chalcidoidea, Pteromalidae) in Europe and Turkey were reviewed, and an identification key for differentiating the species is provided. Newly discovered diagnostic characters of the genus were added to the diagnoses given by earlier authors. Species were recorded as parasitoids of phytophagous Eurytomidae (Hymenoptera: Chalcidoidea). New host and distributions are for Gugolzia harmolitae, which was reared from Tetramesa romana feeding on shoots of Arundo donax (Poaceae), Gugolzia karadagae n.sp. from Eurytoma plotnikovi feeding on fruits of Pistacia vera together with Megastigmus pistaciae (Chalcidoidea: Torymidae) in Gaziantep province, and Gugolzia melengicia n.sp. from fruits of Pistacia terebinthi together with M. pistaciae, Eurytoma sp., and Scophyla sp. (Eurytomidae) in Hatay province, Turkey. The new species are described, their diagnostic characters are illustrated by photographs, and biological data for the species are given.
