Pronotum not sculptured, with two pairs of moderately short posteroangular setae; anteroangular and anteromarginal setae minute. Mesothoracic spinula long, metathoracic spinula absent. Metanotum with transverse lines of reticulation anteriorly, reticulate posteromedially; campaniform sensilla present; two pairs of setae arising at anterior margin. Tarsi 2-segmented. Fore wing with first and second rows of setae complete and closely spaced. Abdominal tergites V–VIII with ctenidia laterally, ctenidia on VIII anterolateral to spiracle; VIII with a posteromarginal comb of microtrichia.

Genus and similar species information
Frankliniella is one of the largest genera amongst Thysanoptera, comprising more than 160 described species. About 90% of the species are from the Neotropics and their taxonomy is usually complex. Almost all members have 8-segmented antennae, three pairs of ocellar setae and fore wing with both rows of setae complete. About 40 species are referred to Brazil, almost half described from this country. Frankliniella nakaharai belongs to the informal minuta group and is characterised by lacking postocular setae I and III, and having ocellar setae III short and arising close together between the posterior ocelli. A key to Frankliniella species recorded from Brazil is provided by Cavalleri & Mound (2012).
Breeding on flowers. Adults were found in Morus nigra (Moraceae) and Baccharis tridentata (Asteraceae) but no host plant data is available.
Economic importance
Not recorded.
