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 notialis is similar to N. ruginosus in having transverse markings between the striae on the anterior third of the pronotum and in the interocellar area. A key to the Neotropical species of Neohydatothrips is provided by Lima & Mound (2016).
