Frankliniella tuttlei

Recognition data

Distinguishing features

Both sexes fully winged. Body and legs mainly yellow with weak brown shading; antennal segment I pale, II–V with apex brown, VI darker than II; fore wing pale. Head slightly wider than long; three pairs of ocellar setae present, pair III shorter than diameter of one ocellus, arising between anterior margins of posterior ocelli; postocular setae pair I present, pair IV shorter than diameter of hind ocellus. Antennae 8-segmented; segments III–IV with forked sensorium. Pronotum with anteromarginal and anteroangular setae scarcely longer than discal setae, 2 pairs of posteroangulars long; one pair of minor setae medially between posteromarginal submedian setae; posteromarginal setae IV no larger than III. Metanotum with 2 pairs of setae close to anterior margin, campaniform sensilla present. Fore wing with 2 complete rows of veinal setae. Abdominal tergites V–VIII with paired ctenidia, VIII with ctenidia anterolateral to spiracle; posteromarginal comb on VIII with long, slender microtrichia on small triangular bases; tergite X clearly shorter than IX. Sternites III–VII without discal setae.

Related and similar species

Californian specimens labeled as F. tuttlei that have been studied from the Ewart Collection at UCR have ocellar setae III arising between the posterior ocelli, posterior to a tangent joining the anterior margins of these ocelli, as illustrated by Sakimura & O'Neill (1979) both for this species and for F. ewarti. These two are currently distinguished by the color of the second antennal segment, and the slightly shorter tenth abdominal tergite of F. tuttlei. The 24 species in the F. minuta group (Sakimura & O'Neill, 1979) are associated with flowers of the Asteraceae, and are known mainly from South and Central America and western USA. Currently 230 species are listed in the genus Frankliniella, with up to 130 further names placed into synonymy (Nakahara, 1997). This high rate of synonymy has been due to the previously unrecognized variability in size and color of so many species.
