Far from home: a new grass-feeding Chirothrips (Thysanoptera, Thripidae) from South Brazil

Chirothrips (Thripidae) includes 44 species, all presumably associated with florets of Poaceae. Most species were described from the Old World, although a few are also known from the Nearctic region. In this study, a new species from the grasslands of southern Brazil, but likely of African origin, is described.

Chirothrips longiventralis sp. nov. is characterized by antennal segment II symmetrical and not laterally projected, simple sense cones on antennal segments III –IV, and a slender and acuminate abdomen.
