Abstract
This chapter provides a checklist for the family Eupelmidae. It provides information on species diversity, host records, distribution records by province in Iran, as well as world distribution. Comparison of the eupelmid fauna of Iran with adjacent countries indicates that the fauna of Iran (48 species) is most diverse, followed by Russia (28 species), Turkey (17 species), Kazakhstan and Turkmenistan (both with nine species), Azerbaijan and United Arab Emirates (both with five species), Afghanistan, Armenia and Pakistan (each with three species), Iraq (two species) and Oman and Saudi Arabia (both with one species); no species have been recorded from Bahrain, Kuwait or Qatar. Russia shares 14 known species with Iran, followed by Turkey (13 species), Kazakhstan (seven species), Armenia and Turkmenistan (both with three species), Azerbaijan (two species) and Oman, Pakistan, Saudi Arabia and United Arab Emirates (each with one species).
