Species of the subfamily Diplazontinae (Hym.: Ichneumonidae) were studied in West Azarbaijan province (Northwest of Iran). The specimens were collected using Malaise traps, during ۲۰۱۹–۲۰۲۰. Five species belonging to three genera were collected and identified. One species, Homotropus riedeli Johansson, ۲۰۲۰ was a new record for Iran as well as Asia. The distribution range of this species extends from Sweden to the north-west of Iran. A checklist is being compiled for ۲۷ known Iranian species of this subfamily. In addition, a distribution map based on the recorded areas for each species within the Iranian provinces has been provided. We proposed a new direction for future biodiversity inventories of this subfamily in Iran.
