Genus Frankliniella

Diagnosis. The genus Frankliniella is distinguished from other genera in the Thripidae by having eight (seven in rare occasions) antennal segments with forked sensory cones on segments three and four. The head with three pairs of ocellar setae. The pronotum with one pair of long anteroangular setae, two pairs of long posteroangular setae and five pairs of shorter setae on the posterior margin ( Sakimura and O’Neill 1979). The mesonotum lacks discal setae ( Mound and Nakahara 1993). The forewings with some exceptions are fully developed with two continuous evenly spaced longitudinal rows of setae. The lateral margins of abdominal tergites V–VIII and occasionally as far forward as tergite III with ctenidia. The ctenidia of tergite VIII are always present anterolateral of the spiracles ( Sakimura and O’Neill 1979). The abdominal sternites III–VII do not have discal setae and the three major pairs of setae on sternite VII arise near or on the posterior margin ( Mound and Nakahara 1993).
