Gall midges (Diptera: Cecidomyiidae) infesting Suaeda monoica (Chenopodiaceae) in Israel

Six new species of gall midges are described from the salt marsh plant Suaeda monoica Gmelin in Israel, the first cecidomyiid species to be described from this host. Five of the new species, Baldratia occulta, n. sp., Izeniola obesula, n. sp., Stefaniola siliqua, n. sp., S. defoliata, n. sp., and S. rufa n. sp., are leaf or twig gallers belonging to a large group of Old World Lasiopterini which is restricted to Chenopodiaceae. Asphondylia acinata, n. sp., is a fruit galler belonging to the Asphondyliini. Descriptions of adults, galls, and larval stages, as available, as well as biological remarks are given for each species. The terminology of female genitalia in the Lasiopterini and the significance of characters of immature stages in this tribe are discussed.
