Six species are currently described in the genus Dorythrips, two from Australia and four from South America (de Borbon, 2009).

Known only from a few specimens taken in flowers of an Acacia species, but this is not neccessarily the plant on which this thrips breeds.
Breeding in flowers of its host.
