Study on Diplazontinae (Hymenoptera: Ichneumonidae) in north central Iran

The fauna of the subfamily Diplazontinae (Hymenoptera: Ichneumonidae) in the north central parts of Iran was studied during ۲۰۱۰-۲۰۱۱. A total of ۹۳۳ specimens were collected in ۳۰ localities at different altitudes using Malaise traps. Sixteen species belonging to ۷ genera were identified of which twelve species indicated by asterisk, are new records for Iran: Diplazon annulatus (Gravenhorst)*, Diplazon laetatorius (Fabricius),D. pectoratorius (Gravenhorst)*, D. tibiatorius (Thunberg)*, Enizemum ornatum (Gravenhorst), Homotropus nigritarsus (Gravenhorst)*, Homotropus pictus (Gravenhorst)*, Promethes sulcator (Gravenhorst), Sussaba flavipes (Lucas)*, Sussaba pulchella (Holmgren)*, Syrphoctonus tarsatorius (Panzer)*, Syrphophilus bizonarius (Gravenhorst)*, Tymmophorus obscuripes (Holmgren)*, Woldstedtius biguttatus (Gravenhorst), Woldstedtius citropectoralis (Schmiedeknecht)* and Xestopelta gracilima (Schmiedeknekht)*. Detailed morphological characters and a key to the genera and species are provided. Flight periods and distribution in relation to altitude on two slopes of the Alborz mountains are discussed.
