Body bicoloured, brown on head, pronotal blotch, metanotum, abdominal tergites VII–X and antecostal ridges of tergites II–VII; mesonotum anterior half brown but posterior half light brown; abdominal tergites I–IV laterally light brown, suffused with brown medially; femora brown with apex and base yellow, tibia brown with base yellow; anterior third of pronotum and tergites V–VI pale. Antennal segments I–II light brown, III yellowish brown, IV yellowish brown on basal half but brown on apical half, V–VIII brown. Fore wing bicoloured with basal, median and sub-apical brown bands contrasting with three pale areas, median pale area suffused with brown. Head with occipital apodeme close to, but not confluent with, the posterior margin of compound eyes; ocellar setae pair III within ocellar triangle, which is transversely striate with internal markings between the striae. Pronotum striate with a few markings between the striae, pronotal blotch distinctively dark brown; mesonotum striate, median setal pair anterior to the lateral; metanotum anterior half transversely striate and posterior half longitudinally striate, with markings between the striae, two pairs of setae at anterior margin; metasternal plate with distinct anterior emargination. Fore wing with sub-apical lobe, second vein with no setae. Tergites II–VI posterior margin with comb of microtrichia incomplete medially, VII–VIII with comb complete; tergite IX with 2 pairs of mid-dorsal setae; sternites III–VI with discal microtrichia medially, absent medially on VII. Both sexes fully winged.
Male similar to female but smaller, sternites without pore plates.

Genus and similar species information
Almost 120 species are included in Neohydatothrips, most from tropical countries (Mound & Tree 2009). All of them have the abdominal sternites and lateral thirds of tergites covered by rows of fine microtrichia, with many of them being bicoloured and with banded fore wings. Neohydatothrips dosulis is remarkable for the distinctive dark pronotal blotch in contrast to the pale anterior third of the pronotum, and it is one of only two species from Brazil with a sub-apical lobe subtending the apical seta on the fore wing. A key to the Neotropical species of Neohydatothrips is provided by Lima & Mound (2016).
