Related and similar species

Hercinothrips is a genus of nine species, all presumably African in origin, but of which two very similar species have become widespread around the world as minor pests on various crops. H. bicinctus has only a short dark band medially on the forewing, whereas H. femoralis has a much longer dark band.
