Occurrence of the genus Erigorgus Forster (Hym., Ichneumonidae, Anomaloninae) in Eastern part of Iran with key to species

Iranian species of the genus Erigorgus Forster, 1869 are taxonomically reviewed. The sampling was done using Malaise traps in Eastern provinces of Iran. Two species, Erigorgus cerinops (Gravenhorst, 1829) and Erigorgus fibulator (Gravenhorst, 1829) are reviewed, of which the second species represents occurrence of this genus in East of Iran. A brief diagnosis based on the reliable morphological characters, as well as an illustrated key to Iranian species are provided. The geographical distribution of the recorded species in the Palaearctic regions is also discussed.
