Striathrips gen.n.

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).
