Additions to the fauna of Iranian Elampini (Hymenoptera: Chrysididae, Chrysidinae), with key to species and taxonomic notes

We provide keys and new distributional data for the Iranian cuckoo wasps of four Elampini genera: Chrysellampus Semenov, 1932, Omalus Panzer, 1801, Philoctetes Abeille de Perrin, 1879 and Pseudomalus Ashmead, 1902. Two species are newly recorded for Iran: Chrysellampus pici (du Buysson, 1900) and Philoctetes kuznetzovi (Semenov, 1932). One new synonymy is proposed: Pseudomalus masalskii (Semenov, 1932) syn. nov. of Pseudomalus turkestanicus (Mocsáry, 1889). The lectotype of Ellampus hypocrita du Buysson, 1893 is designated.
