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 flavicollis is known only from three females, and these are very similar to N. fasciatus but have a shorter mouth cone. A key to the Neotropical species of Neohydatothrips is provided by Lima & Mound (2016).
