Family Gasteruptiidae Ashmead, 1900

The family Gasteruptiidae comprises two subfamilies, Gasteruptiinae (four genera) and Hyptiogastrinae (two genera – see Jennings and Austin 2002), of which only the former occurs in the Palaearctic region (Crosskey 1962). The genera of Gasteruptiinae have been reviewed and keyed by Macedo (2009). Of the four recognized genera only Gasteruption Latreille, 1777 is known from the Palaearctic region. No modern treatment of the Palaearctic species exists, but van Achterberg and Talebi (2014) have reviewed and keyed the species of Iran and Turkey. In Gasteruptiidae the hind tibiae are swollen and the fore wings can be folded longitudinally. They are parasitoids of solitary bees ( Apidae, Colletidae, Megachilidae) and wasps ( Masaridae, Vespidae (Eumeninae) . For biology we referred to Malyshev (1964), 1965) and Jennings and Austin (2004).
