Pronotal epim setae stout and weakly capitate; am, aa, ml and pa setae no more than twice as long as discal setae. Mesonotal spiracles large, often with complex internal sculpture. Metanotum seldom with sculpture medially. Prosternal basantra and ferna developed, mesopresternum slender and transverse. Fore wing of macroptera without duplicated cilia, with three capitate sub-basal setae; microptera wing lobe with one capitate seta. Tergites II–VII without sigmoid wing retaining setae; tergite IX setae capitate. Male sternites without pore plates. Comments . In contrast to the species of the most common leaf-litter Phlaeothripidae in Australia , Psalidothrips , Zemiathrips and Mystrothrips ( Wang et al . 2019 ; Mound 2002 ; Mound & Tree 2018 ), the species of Apostlethrips have the prosternal basantra developed, the body setae shorter, and little sculpture on the body surface. The capitate ocellar setae are particularly unusual in the three species of this genus.
