Mystrothrips Priesner

Seven species are listed in this genus, one from Brazil but the rest from southeast Asia. In Australia, two undescribed species that are considered to be members of this genus have been studied from leaf litter near Brisbane. Tree & Walter (2012: 2903) referred to these as “Gen.n. Phlaeo F and G”, and a few similar specimens have been studied from sites between northern Queensland and Canberra ( Fig. 30 ). These two species have the prosternal basantra very weak or apparently absent, but are otherwise similar in appearance to species described by Okajima (2006) from southern Japan.

Diagnosis. Head usually as long as wide, weakly to strongly prolonged in front of eyes, strongly reticulate dorsally; cheeks incut behind eyes; postocular setae usually well developed; stylets usually wide apart, V-shaped; antennae 8-segmented, VIII constricted basally, III with 2 or 3 sensoria, IV usually with 3; pronotum usually with 5 pairs of capitate setae, notopleural sutures complete or nearly complete; basantra usually present; mesopraesternum strongly eroded; sternopleural sutures present or absent; fore tarsal tooth usually present, sometimes absent in female; fore wings, if developed, without duplicated cilia; pelta variable; tergites without wing retaining setae; tube shorter than head, anal setae shorter than tube or a little longer; male sternite VIII without pore plate.
