Faunistic study of the wasps of the subfamilies Poemeniinae and Xoridinae (Hym.: Ichneumonidae) in Guilan province (Article in English)

The Hyrcanian forest in the north of Iran is a unique ecoregion in the world with high biodiversity including many endemic Iranian species. The family Ichneumonidae is the largest family of Hymenoptera and one of the most important components and bioandicator of forests. This study was carried out to complete the list of the parasitoid wasps of this family in the Hyrcanian forest. Specimens were collected in Guilan province using Malaise traps and sweep net during 2011-2015. The subfamily Poemeniinae was newly recorded for the Iranian fauna with reporting two species, Neoxorides collaris and N. nitens. Four species of the subfamily Xoridinae were reported, two of them, Xorides rufipes and X. praecatorius, were recorded from Iran for the first time. The diagnostic morphological characters and illustrations of these species were provided. Their distribution in the Hyrcanian forest and the Palaearctic as well as their potential important in biological control of forest pests regarding in the possible hosts in Iran were discussed
