Species

Biology

Breeding commonly in the flowers of sunflowers, Helianthus annuus.

Distribution

Widespread in the tropics and subtropics.

Recognition

Small brown thrips with forewing almost uniformly shaded. Antennae 7-segmented, sense cone on III & IV small but forked. Head relatively small, no setae in front of fore ocellus, one pair lateral to ocellar triangle. Pronotum trapezoidal and wider at posterior; 2 pairs of short posteroangular setae, posterior margin with 5 pairs of minor setae; prosternal basantra with 5 or more pairs of setae. Metanotum with irregular lines of sculpture that form a lens-like arrangement on posterior third; median setae not at anterior margin. Forewing first vein with 3 setae on distal half. Tergite II with 3 lateral marginal setae; II-VIII with posterior margin bearing a craspedum of triangular teeth, on VIII these teeth bear long slender microtrichia; tergites V-VIII with ctenidia laterally, on VIII these are posteromesad to the spiracle. Sternites with two irregular rows of discal setae.
