Genus and similar species information This Neotropical genus comprises ten species, all with antennae 9-segmented and the male pore plate placed on the antecostal area of abdominal sternite III. Enneothrips atlanticus is distinct from the other species in the genus for having a metafurca with median spinula and an almost white abdomen, with brown oval spots in the tergites.A key to Enneothrips species is available in Vieira et al. (2024).
