Family Megastigmidae Thomson, 1876.
Abstract This chapter provides a checklist for the family Megastigmidae. It provides information on species diversity, host records, distribution records by province in Iran, as well as world distribution. Comparison of the megastigmid fauna of Iran with adjacent countries indicates that the faunas of Turkey (20 species) and Russia (17 species) are both more diverse than Iran (12 species), followed by Kazakhstan (six species), Armenia (five species), Turkmenistan (three species) and Afghanistan, Azerbaijan and Iraq (each with one species); no species have been recorded from Bahrain, Kuwait, Oman, Qatar, Pakistan or Saudi Arabia. Furthermore, 17 species were recorded from the former USSR. Turkey shares eight known species with Iran, followed by Russia (seven species), Armenia (four species), Turkmenistan (three species) and Afghanistan, Azerbaijan and Iraq (each with one species shared).
