Family Leucospidae Walker, 1834.
Abstract This chapter provides a checklist for the family Leucospidae. It provides information on species diversity, host records, distribution records by province in Iran, as well as world distribution. Comparison of the leucospid fauna of Iran (six species) with adjacent countries shows that it has the same number of species as Turkey, followed by Russia (five species), United Arab Emirates (four species), Afghanistan, Kazakhstan and Turkmenistan (each with three species), Armenia, Azerbaijan and Pakistan (each with two species) and Saudi Arabia (one species); no species have been recorded from Bahrain, Iraq, Kuwait, Oman or Qatar. Furthermore, six species were recorded from the former USSR and if the exact localities of these species were known then the number of species from Russia and Middle Asian countries adjacent to Iran would be increased. All the species recorded from Iran are shared with Turkey, whereas five species are shared with Russia, three species with Afghanistan, Kazakhstan and Turkmenistan, and two species with Armenia, Azerbaijan and Pakistan. Four species are recorded from United Arab Emirates, none of which are yet known from Iran, but Leucospis elegans and L. vanharteni might be expected in southern Iran.
