Species

Thrips setipennis Bagnall

Biology

Found in the flowers of a range of trees, but with little further information.

Distribution

Widespread in the coastal regions of eastern, and south western, Australia.

Recognition

Medium sized brown thrips, forewing dark with base pale; tibiae largely yellow; antennal segment III yellow. Antennae 7-segmented, sense cone on III & IV forked. Head with no setae in front of fore ocellus, one pair just outside anterior margins of ocellar triangle. Pronotum with 2 pairs of relatively long posteroangular setae. Metanotum with transverse lines of sculpture at anterior and close set longitudinal lines on posterior half; median setae close to anterior margin. Forewing first and second veins with complete setal rows. Tergite II with 4 lateral marginal setae; V-VIII with ctenidia laterally, on VIII posteromesad of spiracle; tergite VIII with posteromarginal comb long and regular. Sternites III-VI with up to 6 discal setae, but these arise very close to the posteromarginal setae; sternite VII and all pleurotergites without discal setae.
