(Figs 9, 34, 68, 84, 98, 114, 133)

Described in the genus Euthrips, this species is widespread from South and Central America into the southern USA. In Brazil, this thrips is commonly found breeding on Hibiscus rosa-sinensis (Malvaceae) flowers. Females have mid and hind tibiae uniformly brown, contrasting to the yellow tarsi. Antennal segments III–IV are long and constricted apically, forming a distinctive neck. The posteromarginal comb on tergite VIII is usually shortly interrupted medially, lacking a few teeth. Males have the mid and hind tibiae largely yellow, and abdominal sternites III–VII each bear a large transverse pore plate.
