[email protected] The subfamilies Scelioninae, Telenominae and Teleasinae that were known formerly as Scelionidae are widely distributed in the world. These are parasitic wasps and have important role in the agricultural pests control. These minute wasps are egg parasitoids of spiders and different insect orders. During 2013-2014, a faunistic study was conducted in some parts of East-Azarbaijan province. Collection were made by Malaise trap, pan trap and sweeping net. Identifications were made by available literatures. Morphological characters of head, antennae, thorax, wings, gaster and legs were used for identification. Based on the present study as the first faunistic study of these subfamilies in Iran, 244 specimens were studied. These belong to 10 genera, 21 species. Of which, 11 species and 6 genera, 2 species and 2 genera and 8 species and 2 genera are respectively belong to Scelioninae, Teleasinae and Telenominae. Twenty-one species include 10 genera and three subfamilies were collected and identified. Twenty species and six genera are new records for Iranian fauna. These six genera are Baeus, Baryconus, Calliscelio, Idris, Scelio and Proteleas. The specimens were deposited in the insect collection of the Department of Plant Protection, East-Azarbaijan Research Center for Agriculture and Natural Resources, Tabriz, Iran. Identified species are as follow: Baeus seminulum Haliday, 1833* Proteleas rugosus (Kozlov, 1961)* Baryconus europaeus (Kieffer, 1908)* Teleas rugosus (Kieffer, 1908)* Calliscelio ruficollis Szeleyi, 1941* Telenomus angustatus Thomson, 1861* Gryon muscaeformis Nees, 1818* Telenomus harpyiae Mayr, 1879* Gryon solutus (Kononova and Petrov, 2001)* Telenomus hofmanni Mayr, 1879* Idris aureonitens Szabo, 1965* Telenomus pentophera Mayr, 1879 Idris clypealis (Huggert,1979)* Telenomus punctatissimus Ratzeburg, 1844 Idris desertorum (Priesner, 1951)* Trissolcus cantus (Kozlov & Le, 1977) Idris diversus Wollaston, 1858* Trissolcus cephalotes (Kozlov & Le, 1977) Idris rufescens (Kieffer, 1908)* Trissolcus rufiventris (Mayr, 1907) Scelio rugosulus (Latreille, 1805)* Two genera Telenomus and Idris are the most specious in this region. Including results of this study fauna of the subfamilies Scelioninae, Teleasinae and Telenominae are 16 species and 7 genera, 2 species and 2 genera and 33 species and 3 genera, respectively (totally 12 genera and 51 species). It seems that Gryon muscaeformis and Telenomus harpyiae were the most abundant in the studied area. On the other hand, the most abundant specimens were collected during July that can affected by environmental condition and host abundant.
