Plectrothripini

Belongs within: Phlaeothripidae.

The Plectrothripini is a group of thrips distinguished by having the sensorium on the second antennal segment in the basal rather than the distal section of the segment. The species Lonchothrips linearis is distinctive in having the body sclerotisation much reduced, with the pronotum in particular being largely membranous; in other genera, the pronotal sclerite is well developed, though it is anteriorly eroded in Chirothripoides (Mound & Marullo 1996).

Characters (from Priesner 1960): Whole body strongly flattened. Mouth cone very short, broadly rounded. Antennal segment II with sensorium located between base and center; segments (III or)IV to VII stalked, segment VIII fusiform. Forelegs strongly thickened, flat. Body bristles long, pointed. Pronotal sclerite partially replaced by punctate membrane. Hind tibiae often with spur.
