Abdominal tergites reticulate medially, with one pair of campaniform sensilla close to posterior margin; craspedum not developed; tergite X with one pair of stout thorn-like setae at posterior. Sternites II–VII with 5–10 discal setae, without craspeda.

The genus Limothrips includes six species that are considered to be valid (zur Strassen, 2003). These all live on various grasses. Although they came originally from Europe, three species are now widespread around the world.
Breeding on leaves and in leaf axils of various Poaceae, including cereal crops. Feeding results in the apical leaves turning white on various grasses and young cereal crops (Lewis, 1997).
Originally from Western Europe, but now widespread in temperate areas although apparently not in northern China. Although recorded from Puerto Rico, this species is not usually found in the wet tropics.
