Adraneothrips Hood

Most of the described species in this genus are Neotropical, and a key to 32 of the 59 listed species was provided by Mound and Marullo (1996). However, Stigmothrips Ananthakrishnan with 13 described species from the Asian tropics will be treated as a synonym in a manuscript currently in preparation. Adraneothrips braccatus is the only species currently listed from Australia, but at least three further species are represented in ANIC ( Fig. 1 ). These thrips have all been found in northern Australia from dead grasses and dead leaves. Despite the absence of the metathoracic sternopleural sutures, this genus is possibly related to Hoplandrothrips , although the species exhibit little sexual polymorphism.

Diagnosis. Head with cheeks slightly constricted behind large eyes; postocular setae usually arise behind inner margin of eyes; stylets usually about 1/3 of head width apart, retracted to postocular setae; antennae 8-segmented, III with 2 or 3 sensoria, IV with 3 or 4; pronotum with 5 pairs of capitate setae, notopleural sutures incomplete or weakly complete; basantra absent, mesopraesternum transverse; sternopleural sutures absent; fore tarsal tooth usually not developed; fore wings weakly constricted medially, with or without duplicated cilia; pelta slightly longer than wide and usually bell-shaped; tergites II–VII with 2 pairs of wing-retaining setae, each posterior pair usually thicker than anterior pair; tergite IX with accessory setae between S1 and S2 almost as long as S1; tube with straight sides, slightly shorter than head; male sternite VIII with or without pore plate.
