Antennae 8-segmented; III with external margin produced into a tooth, sensorium simple; sensorium forked on segment IV.

Pronotum with 1 pair of long posteroangular setae, posterior margin with 3 pairs of setae. Metanotum reticulate, campaniform sensilla present, median setae arise behind anterior margin. Meso- and metafurca without spinula. Fore wing first vein with 2 setae on distal half, second vein with about 10 setae. Tergites reticulate medially, paired campaniform sensilla close to posterior margin, craspedum not developed; tergite IX with 1 pair of stout thorn-like setae. Sternites II–VII with 10–16 discal setae, without craspeda.
Male aptera. Head without ocelli; pterothorax transverse without wing buds; tergite IX with 2 pairs of small stout setae on tubercles, 1 pair medially, 1 longer pair laterally; sternites without pore plates.
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 with L. cerealium the most common. L. denticornis is recognisable by the external margin of antennal segment III being strongly prolonged laterally.
