Striathrips sulcatus sp.n.

( Figs 93–97 )

Female macroptera. Body, legs, and antennal segments I–III yellow, IV with light brown shading, V–VIII dark brown; fore wing weakly shaded at base, pale at apex, and with two dark and two light transverse areas, clavus dark. Antennal segments III–IV with apical neck and bearing long, slender, forked sensoria ( Fig. 93 ); III with no microtrichia, IV with a few microtrichia ventrally; external sensorium on V–VI slightly flattened, VIII longer than VII. Head with ocellar setae III long, arising on margins of triangle ( Fig. 94 ); postocular setae small, arising close to margins of eyes. Pronotal inner posteroangular setae longer than external pair, 4 pairs of posteromarginal setae ( Fig. 94 ). Mesonotum transversely striate, anterior campaniform sensilla present; two pairs of setae near posterior margin. Metanotum transversely striate, median pair of setae behind anterior margin, campaniform sensilla present; metascutellum longitudinally striate except near posterior margin ( Fig. 95 ). Abdominal tergite I striate ( Fig. 96 ), campaniform sensilla near posterior margin, craspedum absent medially but weakly developed laterally; II–VIII with campaniform sensilla equidistant from anterior and posterior margins ( Figs 96–97 ); IX with weak transverse sculpture, median dorsal setae well-developed but short. Sternites transversely striate, II with 2 pairs of marginal setae, III–VII with 3 pairs, all arising at margin; craspedum weak, irregular and narrow.
