Kriechbaumerella Dalla Torre, 1897 (Hymenoptera, Chalcididae), a rarely found chalcid genus in Iran

Kriechbaumerella Dalla Torre, 1897 is a relatively small genus of the family Chalcididae and it is rarely collected in Iran. The current paper presents new data on the occurrence and distribution of the Kriechbaumerella species in Iran, representing three species, including Kriechbaumerella hofferi Bouček, 1952, K. gracilis Nikolskaya, 1952 and K. similis (Bouček, 1956). Of which, K. similis is a new record for the Iranian fauna. Some diagnostic characters and geographical distribution of these species were provided and an identification key to Iranian species is prepared.
