The members of this genus are usually extremely bicolored, with complex body structure. The species are morphologically similar to those of Sericothrips and are distinguished by tergites III–VI lacking or having very few microtrichia medially, also longitudinal sculpture on the metanotum without microtrichia. In contrast, in Sericothrips species tergites III–VI are fully covered with microtrichia medially, and the metanotum has transverse lines of sculptures provided with microtrichia ( Lima & Mound 2016b ). Host plant associations are known for only a few species of this genus ( Mound & Tree 2009 ).
