[email protected] The family Chrysididae (Hymenoptera: Chrysidoidea) is one of the largest families of Aculeata. They have a highly reduced sting and only 2 to 4 (rarely 5) metasomal segments are visible. There is no complete information about their biology, but adults feed on pollen and nectar of plants. They are Parasitoid or cleptoparasite of other Hymenoptera, Phasmatodea and Lepidoptera. Members of this family are called gold wasps and cuckoo wasps because of their metallic coloration and cleptoparasitic behavior. Cuckoo wasps are comprising 87 genera and 2509 species in the world. They have the greatest diversity in the Palearctic region. In order to investigate the chrysidid fauna, sampling was carried out in the different ecosystem of Northern provinces (Guilan, Mazandaran, Alborz and Qazvin) and Southern provinces (Hormozgan and Fars) of Iran during 2010-2013 using Malaise traps and sweeping net. The species were identified by reliable keys and confirmed by Paolo Rosa (Bernareggio, Italy). As the result of this research a total of 13 species and 4 genera belonging to Chrysidiane subfamily and Elampini tribe are identified, among them Omalus aeneus (Fabricius, 1787) is recorded for the first time from Iran The specimens were collected from Chamestan in Mazandaran province (23 July 2010, 1 male, 11 August 2011, 3 females). This species has a wide distribution in the Holarctic region. Forest margin and sandy area are the favorite habits of O. aeneus. Crabronidae (Hymenoptera: Apoidea) are reported as its host. The most important diagnostic morphological characters of O. aeneus are as follow: deep and dense punctures on the forehead, pronotum and mesonotum covered whit very small and sparse punctures or smooth, short pubescence of body and shallow apical notch of third metasomal tergum. The females, is completely blue, violet or green, whereas the males are dorsally black and laterally with green or blue reflections. Specimens are deposited in the insect collection of the Department of Entomology, Tarbiat Modares University.
