Adraneothrips Hood

( Fig. 4 )

Adraneothrips Hood, 1925: 54 . Type species: Haplothrips tibialis Hood , by original designation.

Stigmothrips Ananthakrishnan, 1964: 231 . Type species: Stigmothrips limpidus Ananthakrishnan , by original designation.

There are now 77 species listed in this genus, of which four are known from China, and one from the Philippines. Dang et al. (2013), in synonymising Stigmothrips with Adraneothrips , provided a key to the 23 species known from Asia and Australia. Most species in the genus are known from the New World, and in these the prothoracic notopleural sutures are complete, whereas these sutures are incomplete in most of the Asian Adraneothrips species.

Diagnosis: Head with cheeks slightly constricted behind large eyes; postocular setae usually arise behind inner margin of eyes ( Fig. 4 ); 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, mesopresternum 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 setae iS 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.
