Review of the genus Casinaria Holmgren (Hymenoptera, Ichneumonidae, Campopleginae) in Iran

Casinaria is a genus within Campopleginae (Hym., Ichneumonidae) with 125 species worldwide. In this study, as part of the surveys on the ichneumonid diversity, specimens were collected during three surveys in north-central, southern, and north-eastern Iran. Examination of the collected specimens revealed new findings for the genus Casinaria Holmgren, 1859. Four species are newly recorded from Iran: Casinaria horstmanni Riedel, 2018, C. moesta (Gravenhorst, 1829), C. nigripes (Gravenhorst, 1829), and C. pyreneator Aubert, 1960. This study provides identifications based on reliable diagnostic characters, illustrations, zoogeographical distribution data, and an updated list of Iranian species.
