Body colour mainly yellow, with brown markings on head, pronotum, pterothorax and antecostal ridge of abdominal segments; abdominal segments VIII–X yellowish brown; all tarsi yellow and tibiae mainly brown; antennal segments I–III yellow, IV yellow in basal third, V–VIII brown; fore wings pale, slightly brown basally. Head with several transversal lines of sculpture and with an occipital apodeme close to posterior margin of eyes; three pairs of ocellar setae; ocellar region transversely striate. Antennae 8-segmented, III & IV with forked sense cones. Pronotum transversely reticulate on anterior half, but with dark pronotal blotch bearing irregular striae; one pair of posteroangular setae developed; setae on anterior margin not distinctively longer than discal setae; reticles without internal markings. Meso & metathoracic endofurca with spinula present. Metanotum with transverse lines of reticulation anteriorly and longitudinal lines posteromedially; paired campaniform sensilla absent; two pairs of long setae close to anterior margin. Metasternum anterior border rounded. Tarsi 2-segmented. Fore wing with first setal row essentially complete and second vein with only two setae. Abdominal tergites I–VIII covered with microtrichia arranged in closely spaced rows; II–VIII with a pair of long close together median setae; VIII with long posteromarginal comb of microtrichia. Sternites covered with microtrichia, including medially; three pairs of long posteromarginal setae.
Male without pore plates on abdominal sternites.
Intraspecific variation
Antennal segment III sometimes slightly shaded; abdominal segments VIII–X sometimes paler.
Genus and similar species information
Neohydatothrips includes about 100 species, mainly from tropical countries (Mound & Tree 2009). They all have abdominal sternites and lateral thirds of tergites covered by rows of fine microtrichia. It is closely related to Hydatothrips but the metasternal anterior border differs in being transverse (Lima & Mound 2016a). Neohydatothrips flavens has yellow body colour and the fore wing is extensively but weakly shaded, with an indistinct paler area medially and the extreme apex pale. A key to the Neotropical species is provided by Lima & Mound (2016a).
Breeding on leaves; very abundant on Dodonaea viscosa (Sapindaceae) leaves in South Brazil.
Economic importance
Not recorded.
