Species not studied in the present work. This is a brown species which has fore wing with a sub-basal pale area. It is distinctive in having abdominal tergite IX remarkably longer than X (IX about 1.5 times as long as X). Abdominal tergites bear a fringe of independent posteromarginal microtrichia, and males lack sternal pore plates (Pereyra & Cavalleri 2012).

Genus and similar species information
Heterothrips Hood is the largest genus in the family Heterothripidae, currently comprising more than 70 species. It is restricted to the Americas and two informal groups were proposed by Moulton (1932). Species placed in “group I” bear a posteromarginal fringe of independent microtrichia on the abdominal tergites, whereas species in “group II” have microtrichia that arise on the posterior margin of the tergites from a well-developed craspedum. Antennal segments III & IV each bears apically a circumpolar sensorium with one or more rows of pores. A key to Heterothrips species recorded from Brazil is given by Pereyra & Cavalleri (2012).
