mesoscutum with parapsidal grooves distinct and complete; scutellum with only two long pairs of bristles; fore wing with marginal vein long, much longer than stigmal, the postmarginal long; marginal vein in males of subfamily Platynocheilinae broadened, sausageshaped; tarsi with five segments, except in males of subfamily Tetracampinae having tarsi four segmented (NIKOL'SKAYA 1952; BOUCEK 1958, 1965, 1988, 1997; GRAHAM 1963; YOSHIMOTO 1978; NIKOL'SKAYA &TRJAPITCYN 1978; PRINSLOO 1980) In Europe and Turkey, there are two subfamilies, Platynocheilinae and Tetracampinae The characters of the subfamilies are given in the key to subfamilies of Tetracampidae (BOUCEK 1958) Platynocheilinae consist of one genus, Platynocheilus WESTWOOD, ???, with three species which parasitize Agromyzidae (Diptera) and Pteromalidae (Hymenoptera) (BOUCEK & ASKEW 1968; BOUCEK 1993) Tetracampinae include genera and 21 species in the world, and the species are parasitoids of eggs and larvae of Chrysomelidae (Coleoptera) and Agromyzidae (BOUCEK & ASKEW 1968) BOUCEK (1958) and PECK et al (1964) worked on European species, MANI (1971) on Indian species, BOUCEK (1988) on Ausralasian species, YOSHIMOTO (1975, 1978) and BOUCEK (1993, 1997) on Nearctic species These are the main references on Tetracampidae, all of them gave diagnostic characters for the subfamilies, the genera and their species, including biological and distributional data for the species In the recent catalogue (NOYES 1998) the number of described species in the world are of Platynocheilus: Nearctic, Palearctic, Holoarctic; of Epiclerus: Nearctic, Palearctic, Australasia; of' Foersterella: Palearctic and Australian Some undescribed ones were also reported by BOUCEK (1988) from several parts of the world In Turkey, DOGANLAR (1985) recorded two species from Eastern Anatolia In the present work, the Turkish species of Tetracampidae are studied, an identification key for the subfamilies, genera and their species are provided, four new species are described and illustrated, and available biological data of some species are given Some material was reared from host(s) or from material with which the host(s) are associated Other specimens were swept from pastures Key to Tetracampidae concerning Turkey (BOUCEK 1958,1997) Body long and narrow, with pronotum almost as long as broad;
