Casinaria Holmgren and Dusona Cameron (Hymenoptera: Ichneumonidae) in Iran: distribution extension

This study is carried out to present new species records and new distributional data of the genera Casinaria Holmgren and Dusona Cameron (Hymenoptera: Ichneumonidae, Campopleginae) from Iran and also to provide the illustrated taxonomic notes on their diagnostic morphological characters. Specimens were collected using Malaise traps during 2013, 2015 and 2016 from Fars, Kerman and Mazandaran provinces. Four species present here as Casinaria kriechbaumeri (Costa, 1884); Casinaria trochanterator Aubert, 1960; Dusona cultrator (Gravenhorst, 1829) and Dusona erythrogaster (Förster, 1868). Two species i.e. D. cultrator and D. erythrogaster are newly reported from Iran. Data about distribution of D. rugifer and D. stygia in Iran as part of eastern Palaearctic fauna is updated to the western Palaearctic realm, based on collecting sites in Iran (D. rugifer from Golestan province and D. stygia from West Azerbaijan province). Available data on adult flight period of Iranian species of Casinaria and Dusona may indicate that five species are univoltine and the others are bivoltine.
