اولین گزارش Holarthrothrips indicus Bhatti & Ananthakrishnan, 1978 (Thysanoptera: Stenurothripidae) از ایران

The family Stenurothripidae, originally erected based on the fossil genus Stenurothrips Bagnall is one of nine families recognised in the Thysanoptera. Hitherto, only three genera are recognised in this family, worldwide. All four species of the genus Holarthrothrips Bagnall breed in the male flowers of date palms and its relatives and are found between India and the Mediterranean area including the Canary Islands. In contrast, Oligothrips Moulton and Heratythrips Mound & Marullo are both known only from western North America. Stenurothripidae all have nine antennal segments, of which the distal segments are fully distinct from each other, segments II–IX bear transverse rows of prominent microtrichia, and the sensoria on segments III and IV have a characteristic, broadly conical shape. The species of Holarthrothrips have the metanotum with concentric rings of sculpture bearing microtrichia, antennal segment IX is about five times longer than wide, tergites VIII–VIII with complete posteromarginal comb of microtrichia, sternite VII with four (or three) pairs of postermarinal setae and about three pairs of discal setae laterally, sternites IV–VII often with discal setae laterally. Only one species, H. josephi Bhatti has hitherto reported from Iran. H. indicus Bhatti & Ananthakrishnan is reported here for the first time from Iran, based on eight females and four males collected from Kerman province, Shahdad, on male flowers of date palm, 28.iii.2015. Recently, this species has been newly discovered in southern China. H. indicus is very similar in colour and structure to H. josephi. However, H. josephi lacks campaniform sensilla on abdominal tergite I and tergites II–VI have the posteromarginal comb of fine microtrichia complete medially.
