Thrips pallisetis Sakimura

Thrips (Isothrips) pallisetis Sakimura, 1969: 71

Diagnosis: Body brown, tibiae yellow with light brown shadings; antennal segment III yellow; forewings weakly shaded. Antennae 7­segmented; ocellar setae III arise outside ocellar triangle. Pronotum with weak transverse markings, posterior sub­marginal apodeme present, postero­angular setae long. Metanotum with irregular elongate reticulation ( Fig. 70 ), median setae at anterior margin, campaniform sensilla present. Forewing first vein with setal row complete. Abdominal tergite II with 4 lateral margin setae; chaetotaxy and ctenidia of tergites V–VII typical of Thrips, VIII with ctenidia terminating anterior to setae S3 ( Fig. 71 ), posteromarginal comb present laterally; sternites and pleurotergites with no discal setae.

Breeding: Known only from four females, nothing is known of the biology of this species.

Distribution: An Australian endemic, this species presumably lives in the arid inner area of Australia, three females having been taken near Bourke, in New South Wales, and one female just south of the border between Northern Territory and South Australia, at Marla on the Stuart Highway.

Relationships: The position of the ctenidia on tergite VIII indicates that this species is a member of the Australian endemic T. seticollis group, although it is the most northerly member of the group. The metanotum is similar in structure to T. excaelatus , but the forewing first vein has a complete row of setae.
