Diagnosis. Macropterous Thripinae , Body surface with many closely spaced transverse striae ( Figs 94-97 ); antennae 8-segmented, segment I with one dorso-apical seta, III–IV with long forked sensoria. Head with ocellar setae I absent; compound eyes with no pigmented facets. Pronotum with 2 pairs of posteroangular setae; pronotum, metanotum, tergites and sternites with numerous transverse striae. Prosternal basantra without setae, ferna complete; meso and metafurca without spinula. Fore wing with setal rows widely spaced, clavus with discal seta. Tergites II–VIII with craspedum of small lobes; IX with 2 pairs of campaniform sensilla, median dorsal setae short; X with no longitudinal split; sternites with weak, narrow craspedum, VII with all setae arising at margin. Type species Striathrips sulcatus sp.n. Comments . Relationships of the new species described below are far from clear. The lobed tergal craspeda and presence of one dorso-apical seta on the first antennal segment suggest a relationship to Bregmatothrips , but the tergal campaniform sensilla are placed far forward from the posterior margin of each tergite, and ocellar setae pair I are not present. The dense transverse striae on the tergites and sternites are unusual, but are reminiscent of Amalothrips flacidus from India , as illustrated by Bhatti (1975) .
