Oidanothrips Moulton

Oidanothrips Moulton, 1944: 267 . Type species: Oidanothrips magnus Moulton , by monotypy.

This genus of fungus-feeding species with remarkably elongate stylets is closely related to Holothrips , but has four sensoria on the third antennal segment. Most of the 12 species included are from various countries in Southeast Asia ( Okajima 1999b), of which three are recorded from southern China. A further species, notabilis Feng, Guo & Duan , was described from Henan province in China, based on four females and one male ( Feng et al. 2006). The original description indicated that the postocular setae and fore wing sub-basal setae S3 are blunt apically. However, the types have been checked in this study, and these setae were found to be sharply pointed. The other characters given for notabilis do not differ from the redescription of frontalis by Okajima (2006), and one female of frontalis has been studied in ANIC with pointed setae. For these reasons, Oidanothrips notabilis Feng, Guo & Duan (2006) is here considered a new synonym of frontalis (Bagnall) .

Diagnosis: Head much longer than wide; eyes normal, 1 or 2 pairs of postocular setae well-developed; stylets very long, retracted to eyes, close together for full length of head; antennae 7-segmented, VII with complete or incomplete suture, III with 4 sensoria, IV with 4; pronotum with 5 pairs of developed setae, sometimes am reduced, notopleural sutures complete; basantra absent; mesopresternum transverse; sternopleural sutures present; fore tarsal tooth present in both sexes; fore wings parallel-sided, with numerous duplicated cilia; pelta bell-shaped; tergites II–VII with 2 pairs of wing-retaining setae; tube shorter than head; male sternite VIII without pore plate.
