Species not studied in the present work. However, this dark brown species is characteristic by having antennal segments I–V largely pale, and abdominal tergite VI with marginal fringe widely interrupted (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).
