Systasis edlandi - a new species of Ormocerinae (Hymenoptera, Pteromalidae) from Norway associated with rowan berry (Sorbus aucuparia) (Rosaceae)

Systasis edlandi n. sp. is described from Norway, representing a new species of Systasis Walker, 1834. Discrimination from the closest species is discussed briefly. The material is a result of an extensive hatching project from rowan berry (Sorbus aucuparia) run by the late Torgeir Edland. Even though the exact circumstances about the biology can be recalled, it is to believe that the host is a gall midge (Diptera, Cecidomyiidae). Posted here with permission from the journal.
