Frankliniella gemina Bagnall ( Fig. 33 )

Diagnosis. This pale species is similar to Frankliniella gossypiana (Morgan) and Frankliniella suramericana Skarlinsky and Rugman-Jones. The presence or absence of microtrichia on the upper hind coxae and discal setae on the abdominal sternite II separates the three similar congeners.

Distinguishing features. Color. Body, wings and legs pale ( Fig. 33A ). Pigmented ventral eye facets with the 1-1-2 pattern. Structure. Head with the PO1 setae, OC3 setae in position 2B ( Fig. 33B ). Pronotum usually with 4 mAM setae ( Fig. 33C ). Upper surface of the hind coxae with microtrichia. Abdominal sternite II without discal setae. Abdominal tergite VIII posteromarginal comb complete. Tergite IX B1 setae usually less than 100 µm ( Fig. 33D ).

Interception frequency. Uncommon.

Region(s) of interceptions. South America.
