This species has not been studied by the present authors.
The genus Poecilothrips currently includes three species; P. albopictus is widespread, one species is from South Africa, and P. dens Moulton is from California. This third species is known from only two specimens (Cott, 1956) and, since the metanotum is longitudinally reticulate rather than striate (Mound & Marullo, 1996), it is possibly not closely related.
