In each report submitted, faunistical, taxonomical and nomenclatural information are revised as far as possible, updated accordingly, with footnotes. References to the faunal information of some states published in recent years are also mentioned in the related reports. The following states are newly added to the research program on the pterygot fauna within the frame of entomofaunal surveys of the Cesa Austria, Bulgaria, Creta, France, Germany, Greece, Hungary, Italy, Macedonia, Romania, Spain, Sweden and Ukraine in Europe; Afghanistan, China, Cyprus, Israel, India, Iraq, Jordan, Japan, Kazachstan, Kirgizistan, Lebanon, Sri Lanka, Nepal, Pakistan, Syria, Saudi Arabia, Thailand, Tadjikistan, Turkmenistan, Taiwan, Uighur Ili, Uzbekistan, and Yemen in Asia; Argentina, Brazil, Chile, Colombia, Costa Rica, Mexico, Peru, Surinam, United States, and Venezuela in America.
