Type species: Drepanothrips reuteri Uzel, 1895 , by original designation and monotypy. Female . Macropterous. Head wider than long, with interantennal projection broad and about 0.5 times as wide as width of first antennal segment (Fig. 4 A); mouth-cone not elongate, with 3 -segmented maxillary palpi. Compound eyes without pigmented ommatidia. Ocellar setae I present; setae III short. Postocular setae four pairs. Antennae 6 -segmented, segment I without dorsal apical setae, II with an inner dorsal apical setae longer than outer seta, III and IV with sense-cones forked, III to VI with some rows microtrichia on both dorsal and ventral surfaces (Fig. 4 B). Pronotum wider than long distinctly sculptured with transverse anastomosing striae, without long posteroangular setae, but with four pairs of setae on posterior margin, B 2 setae the longest (Fig. 4 A). Mesonotum distinctly sculptured with transverse striae; median pair of setae situated far from posterior margin and much anterior to submedian setae; CPS absent anteromedially (Fig. 4 C). Metascutum reticulated; CPS absent (Fig. 4 C). Metaepimeron with two setae. Metaepisternum without setae. Metapreepisternum developed with one seta. Prosternal ferna barely divided at middle; basantra membranous, without setae (cf. Fig. 18 A). Mesosternum with sternopleural suture complete, reaching at anterior margin; endofurca with spinula (cf. Fig. 18 A); spinasternum narrow and curved posteriorly at middle. Metasternal endofurca with spinula (cf. Fig. 18 A). Fore wing first vein with long gap in setal row; second vein with four setae; clavus with four veinal and one discal setae; posteromarginal fringe cilia wavy. Tarsi 2 -segmented. Abdominal terga without ctenidia and posteromarginal craspeda, not clearly divided from laterotergites; terga I to VII with B 1 setae wide apart from each other than their length ( Fig. 5 A); terga II to VIII with numerous ciliate microtrichia along lines of sculpture at each side; tergum VIII with posteromarginal comb complete (cf. Fig. 15 A); tergum IX without CPS ; tergum X without median slit; sterna with numerous ciliate microtrichia along lines of sculpture at each side, without discal setae and posteromarginal craspeda; sterna III to VII with three pairs of posteromarginal setae, but II with two pairs; sternum VII with all setae at posterior margin. Ovipositor developed. Male . Macropterous. General structure as in female; abdominal tergum IX with drepanae ( Fig. 5 B). Comments . This genus includes only a single species, and although this has a unique 6 -segmented antenna the rest of the body structure is very similar to that of Scirtothrips species.
