Head with striate sculpture including the ocellar region; three pairs of ocellar setae present. Antennae 9-segmented, III & IV with forked sense cones. Pronotum transversely striate; only one pair of long posteroangular setae, no long setae on anterior margin. Meso and metathoracic endofurca without spinula. Metanotum transversely striate on anterior region, reticulate with internal markings posteromedially; campaniform sensilla absent; two pairs of stout setae. Fore wing first vein setal row largely incomplete, second vein setal row complete and closely spaced. Abdominal tergites II–VII with several lines of sculpture laterally; II–VII with a pair of long and close together median setae; II–VII with an incomplete posteromarginal comb of microtrichia, VIII with a complete comb. Sternites with three pairs of long setae arising ahead of posterior margin.
Male macroptera and smaller than females; with a glandular region between sternites II and III.
Intraspecific variation Not recorded.
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 fulbrightae is similar in coloration and sculpture to E. fuscus, but it can be distinguished by the absence of microtrichia on the lateral transverse lines of abdominal tergites I–VIII.A key to Enneothrips species is available in Vieira et al. (2024).
