Diplazontinae (Hymenoptera: Ichneumonidae) of the West Azarbaijan province with a new record for the Iranian fauna

Abstract

Species of the subfamily Diplazontinae (Hym.: Ichneumonidae) were studied in West Azarbaijan province (Northwest of Iran). The specimens were collected using Malaise traps, during 2019-2020. Five species belonging to three genera were collected and identified. One species, Homotropus riedeli Johansson, 2020 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 27 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.
