Bradythrips Hood & Williams

( Fig. 29 )

Bradythrips Hood & Williams, 1925: 68 . Type species: Bradythrips hesperus Hood & Williams , by monotypy.

This is a small genus of six species, all of which are reported from SE Asia, despite the type species having been described originally from Guyana in South America. As with the related urothripine genera, Baenothrips and Stephanothrips , the species are fungus-feeding and are usually found on dead branches or in leaf-litter.

Diagnosis: Head longer than wide, tuberculate dorsally and laterally, produced in front of eyes, with 1 pair of prominent knobbed setae ( Fig. 29 ); eyes developed in macroptera, with facets separated; all head setae short and expanded, usually arising from tubercles; stylets retracted to eyes, close together medially; antenna 7-segmented, segment VII with or without distinct suture, III with 1 sensorium, IV with 2; pronotum with irregular sculpture and numerous tubercles, most setae short but epim elongate, notopleural suture reduced; basantra reduced or small; mesopresternum developed; fore tarsal tooth absent; usually apterous; pelta distinctly separated from tergite II or not; tergites reticulate strongly or weakly; tergites II–VII with a pair of fin-shaped wing-retaining setae in macroptera; segments IX–X elongate, tube longer than head, with 1 or 2 pairs of anal setae elongate, about 3 times as long as tube, other anal setae reduced.
