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 fuscicornis is a brown species which is known only from one poorly mounted female. Possibly belongs to the informal minuta group of species, with ocellar setae III on the head minute, although the pronotal setae are relatively long. A key to Frankliniella species recorded from Brazil is provided by Cavalleri & Mound (2012).
