Body dark brown, yellowish only on tergite X, lateral areas of VI, and anterior margin of pronotum; fore wing dark with pale sub-basal band and diffusely paler median area, clavus with stout black setae; antennal segment I light brown, II pale, III pale medially but base and apex light brown, IV basal half pale and apical half brown, V–VIII brown; femora dark brown, tibiae and tarsi yellowish; major setae on wings and pronotum stout and black. Head with occipital apodeme confluent with posterior margin of eyes, ocellar area striate; antennal segments III & IV slender with apex not constricted to a neck. Pronotum transversely striate, pronotal blotch well-defined with anteromarginal setae irregularly arranged, posteroangular paired setae long and dark. Mesonotum and anterior part of metanotum closely striate; metasternal plate with shallow anterior emargination. Fore wing second vein with no setae, clavus with 4 long veinal setae and one long discal seta.

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. This group is closely related to Hydatothrips, but anterior margin of metasternum is transverse or with weak emagination. Neohydatothrips clavisetis is one of the darkest species of Neohydatothrips in South America, and is remarkable for the stout black setae on the fore wing clavus. A key to the Neotropical species of Neohydatothrips is provided by Lima & Mound (2016).
