Pronotal anterior area with broad transverse reticulations without internal markings, pronotal blotch in part transversely striate; mesonotum and metanotum striate; metasternal plate with shallow emargination. Fore wing second vein with no setae. Tergites II–VIII with complete comb of microtrichia on posterior margin, comb short on anterior tergites; tergite IX with 2 pairs of mid-dorsal setae.

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 fimbriatusis similar to N. basilaris in having a complete fringe of microtrichia on the posterior margin of tergites II–VIII. A key to the Neotropical species of Neohydatothrips is provided by Lima & Mound (2016).
