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 recorded from Brazil, and almost half of these were described from this country. Frankliniella minuta can be distinguished from the other Frankliniella species by the short ocellar setae III and the lack of metanotal campaniform sensilla. A key to Frankliniella species recorded from Brazil is provided by Cavalleri & Mound (2012).
World distribution
Widespread in Central America and also recorded from Brazil, Colombia, Peru and USA.
