Chirothrips manicatus (Haliday) .

The record from the Hawaiian Islands of this common grass thrips of temperate countries was considered doubtful by Mound et al. (2016), but an overlooked report by Krushelnycky et al. (2007) indicated that the species had been found at Haleakala National Park, Maui, during a survey between 2001 and 2004, and in July 2016 substantial populations were found on the upper slopes of Haleakala within the national park. As with other species of Chirothrips, this thrips breeds and pupates within the florets of grasses, and it is thus easily distributed in commercial grass seed. Moreover, it seems to be catholic in the range of Poaceae on which it can breed, and large populations have been studied from Australian native grass species in montane areas of Tasmania.
