Related and similar species

Females of the genus Limothrips are characterised by the presence of a pair of unusually stout setae on the ninth tergite. Eight species are listed in this European genus, although two are of doubtful validity. Three species are now widespread around the world in temperate areas, and all three have been found in southern areas of Australia. L. angulicornis is recognised by antennal segment II being prolonged into a lateral tooth.
