The species of the genus Dusona Cameron, ۱۹۰۱ (Hymenoptera: Ichneumonidae: Campopleginae) are studied in four provinces of Iran (Mazandaran, Guilan, Alborz and Fars). Specimens were collected using Malaise traps during ۲۰۱۰–۲۰۱۲. Eight species of Dusona were collected and identified, among them three species, D. libertatis (Teunissen, ۱۹۴۷), D. limnobia (Thomson, ۱۸۸۷), and D. disclusa (Förster, ۱۸۶۸) represent new records for the fauna of Iran. Morphological characteristics of the newly recorded species are illustrated. Additionally, an updated checklist of Dusona species known from Iran is provided, along with zoogeographical distribution maps for all species collected in this study.
