نخستین گزارش از حضور جنس Macroteleia Westwood (Hym.: Scelionidae) در ایران

In the subfamily Scelioninae, Macroteleia Westwood is a cosmopolitan genus, with over 130 species. Species of the genus Macroteleia are spread worldwide, except Antarctica, but they are mainly found in the tropics and subtropics. The members of this genus are solitary egg parasitoids of long-horned grasshoppers (Orthoptera, Tettigoniidae). During the PhD project survey of the first author on the superfamily Platygastridae, we found a single specimen that was collected from East-Azerbaijan province, Khosroshah (36°58'28''N, 46°02'55''E), July 2014 via Malaise trap. Based on the available keys and descriptions of species it was identified as Macroteleia viticola Kononova and Petrov that is the first record for Iran. It was recorded from Greece and its biological association is unknown. Macroteleia contains some of the largest scelionids, it may be distinguished from other genera of the subfamily by the combination of the following characters: unarmed propodeum, wing hyaline or subhyaline rarely with infuscations or darkening, the marginal vein as long as, or longer than the stigmal vein, T6 in females strongly compressed, the apex of T7 in males differentiated, truncate or excavate medially, pointed medially or cut off, but never bidentate or bio spinose. The species M. viticola is easily distinguished from other species by the following characters: head slightly wider than mesonotum; vertex without transverse keel, occiput and crown between lateral ocelli with fine-grained sculpture, forehead over antennae without frontal depression, without longitudinal keel; eyes pubescent; antennae 12-segmented, filiform; mesoscutum with distinct notauli, with fine-meshed sculpture; wings well developed. Fore wings 3.4 times as long as wide; all tergites and sternites with longitudinal wrinkles.
