Drepanothrips reuteriDrepanothrips reuteriBoth sexes fully winged. Body, antennae and legs light brown, with tergal antecostal ridges darkest; fore wing weakly shaded. Antennae 6-segmented, segments III–IV each with a small forked sense cone. Head wider than long, with lines of sculpture between ocelli; three pairs of ocellar setae present, pair III close together within ocellar triangle; maxillary palps 3-segmented. Pronotum with transverse lines of sculpture widely spaced, one pair of prominent posteroangular setae. Mesonotal median setae arise well in front of posterior pair. Metanotum reticulate, median setae near anterior margin. Fore wing first vein distal half with 3 setae, second vein with 4 widely spaced setae. Abdominal tergites with no sculpture medially, closely spaced rows of microtrichia on lateral thirds; tergites II–VI median setae widely spaced, on VIII longer than distance between their bases; tergite VIII with long posteromarginal comb of microtrichia.
Male smaller; abdominal tergite IX with pair of long dark drepanae laterally extending beyond abdominal apex.
Only one species is placed in the genus Drepanothrips. This is similar in structure and biology to the species of Scirtothrips, but has the terminal three antennal segments fused into one large segment.
Feeding and breeding on the leaves of various tree species, including Betula and Corylus [Betulaceae] and Quercus [Fagaceae], but also Vitis vinifera [Vitaceae].
Widely distributed in Britain from Dorset to Inverness, but infrequently collected (Mound et al., 1976). This species was collected in large numbers (by insecticide fogging) from the canopy of Quercus trees in Richmond Park, London (Palmer, 1986). It is widespread in Europe, from Norway and Sweden south east to Turkey (e.g., zur Strassen, 2003; Tunç & Hastenpflug-Vesmanis, 2016) and on to Iran.
