In the course of study of Thysanoptera fauna of forests and rangelands in Khuzestan province, a specimen collected on Teucrium oliverianum Gingins and Stipa capensis Thunb. on March 2002 in the Shahion area of Dezful (500m height) was identified and confirmed as Rhipidothrips unicolor by Dr. R. Zur Strassen. Formerly, 4 species in this genus have been reported from Iran and this is a new record for the fauna of Iran. Rhipidothrips unicolor can be distinguished by antennal segment II dark brown, Setae on posterior margin of pronotum short, at the most up to 25 µm long, often only 2 pairs of these setae are present, Lower vein of fore wing with mostly 11–20 setae, or the insects are brachypterous. Apices of middle and hind tibiae are dark, tarsi likewise dark. Internal body pigment is yellow to orange colored. Fore wing brownish-gray, setae on veins grayish brown. Setae on abdominal tergum IX brownish yellow, sometimes even pale yellow. Antennal segment III 46–57 µm long, 1.2 to 1.4 times as long as segment IV which is 39–46 µm long.
