Frankliniella bagnalliana
Hood
(
Fig. 15
)
Diagnosis.
This species was added by
Retana-Salazar and Mound (1995)
to the minuta group series proposed by
Sakimura and O’Neill (1979)
. Members of this group have short OC3 setae and rather compact antennal segments (
Fig. 15A
). A combination of characters and states distinguishes
F. bagnalliana
from other members of the group. These include, the B1 setae being shorter than the length of abdominal tergite IX, the head usually with the PO1 setae, and with the AM setae less than 30 µm.
Distinguishing features.
Color.
Body dark, forewings dark, basally pale, legs dark with femora and tibiae indistinctly shaded from dark to pale.
Structure.
Head with the PO1 setae, OC3 setae short and in position 2B (
Fig. 15B
). Pronotum with 2 mAM setae (
Fig. 15C
). Abdominal tergite VIII posteromarginal comb complete. Abdominal tergite IX B1 setae equal to or shorter than tergite X is long (
Fig. 15D
).
Interception frequency.
Rare.
Region(s) of interceptions.
North America.
Comments.
The mid and hind tibiae can be shaded from pale to dark within the same or between different populations (
Mound and Marullo 1996
).
