چکیده
The hymenopteran family Platygastridae, consisting of two subfamilies viz. Platygastrinae and Sceliotrachelinae, is a large group of exclusively parasitoid wasp. Members of the subfamily Sceliotrachelinae attack hosts including adult Hemiptera or the eggs of Coleoptera. During our study on Platygastridae, we found a single specimen that was collected from Fars province, Dasht-e Arzhan (51°58′N, 29°38′E, 2020 m), on August 9, 2015, via Berlese Funnels and later identified based on morphological characters using available literatures. It belonged to the genus Fidobia Ashmead that has not been reported from Iran. These wasps, reported as endoparasites of beetle eggs (Chrysomelidae and Curculionidae), are minute species and rarely collected. This genus belongs to the subfamily Sceliotrachelinae with 9- or 10-antennal segments, in female with three incrassate clavomeres. Species of Fidobia are very small with dorsoventrally compressed body, second tergite in most species the largest with two anterior depressions anterolateral. The genus Fidiobia Ashmead contains 48 described species worldwide, of which seven are known from the Palaearctic. Based on the available key of species, it was identified as Fidobia hofferi Kozlov that was confirmed by fourth author. This species is easily distinguished from other species by the following characters: Antenna 9-segmented; mesoscutum with incomplete notauli; pronotum hardly visible in dorsal view; T1 almost trapezoidal and T2 smooth, shining, glabrous, without visible sculpture with two large depression anterolaterally. Specimens are deposited in insect collection of the Department of Plant Protection, East Azerbaijan Research and Education Center for Agriculture and Natural Resources, Tabriz, Iran. Hitherto, four genus (Allotropa, Amitus, Isolia and Afrisolia) and eight species of subfamily Sceliotrachelinae are reported from Iran. Fidiobia hofferi has already been reported from Czech Republic Finland, Sweden and former USSR. This is the first report of the genus and species for Iran insect fauna.
