Body dark brown; tarsi brownish yellow and tibiae mainly brown, antennal segments III–V yellow; fore wing brown with paler sub-basal band. Head strongly sculptured and not distinctly constricted behind eyes; ocellar region strongly elevated. Antennae 8-segmented, III & IV with simple sense cones. Pronotum reticulate, without long setae. Meso and metathoracic endofurca without spinula, with short arms. Mesonotum with sculpture converging posteriorly in midline, forming a longitudinal division medially. Metanotum with reticulate median area, campaniform sensilla present, one pair of setae near posterior margin. Tarsi 2-segmented. Fore wing first and second veins with setal row incomplete; veinal setae minute. Abdominal tergites II–VIII with pair of small median setae; lateral thirds and anterior margin with reticulate sculpture; VIII with posteromarginal craspedum; X elongate, with complete longitudinal division. Sternites with entire craspedum, three pairs of small posteromarginal setae. Both sexes macropterous or micropterous.

Intraspecific variation
Most individuals collected in Southern Brazil are short-winged.
Genus and similar species information
The genus Dinurothrips includes only two species, both Neotropical, and both with strong body sculpture and major setae on the fore wings rather small. Males have curious U-shaped pore plates on the abdominal sternites. Dinurothrips vezenyii can be easily separated from D. hookeri by the tarsi 2-segmented and the mesonotum with a median longitudinal pseudodivision.
World distribution
Described from Argentina, it is commonly found in Southern Brazil. Known also from USA.
