Members of this pantropical genus can be distinguished from the other two genera of this subfamily by having the metasternal plate anterior border with deeply U or V shaped emargination, usually more than half as deep as length of this sclerite. In contrast, Neohydatothrips and Sericothrips have the metasternal plate anterior border transverse, or with shallow emargination ( Lima & Mound 2016a ).
