Recognition data

Distinguishing features

Female macroptera. Body brown, legs yellow; antennal segments I–II brown, III–IV yellow, V brown with base sometimes paler, VI–VIII brown; fore wings shaded with base paler. Antennae 8-segmented, segment I without dorso-apical setae; II–VI with transverse rows of microtrichia: III–IV with stout forked sensorium; base of sensorium on VI oval; VIII long and slender with many fine microtrichia. Head wider than long, cheeks slightly incut behind eyes, ocellar triangle reticulate; 3 pairs of ocellar setae, pair III on anterior margins of triangle; 5 pairs of postocular setae, pair I as long as ocellar setae III. Compound eyes with many small tubercles among dorsal ommatidia, no pigmented facets. Maxillary palps 3-segmented. Pronotum with 20–50 discal setae; one pair of elongate posteroangular setae; 3–5 pairs of posteromarginal setae. Prosternal basantra without setae, ferna entire; meso and metafurca each with strong median spinula. Mesonotum transversely striate/reticulate with markings between major lines; anterior campaniform sensilla present; median setal pair arising well in front of margin. Metanotal sculpture variable, elongate narrow reticulate/striate, usually with markings between main lines; campaniform sensilla present. Fore wing first vein with almost continuous setal row, distal setae more widely spaced; second vein with continuous setal row; clavus with 5–8 veinal setae, one discal seta; cilia strongly wavy. Abdominal tergites without craspedum; tergites II–VI with about 7 rows of discal microtrichia laterally that extend to setae S2, on VII extend to setae S1, on VIII extend across tergite; III–VI with posteromarginal setal pair arising mesad of posterior angle; median setae small and wide apart, posteromarginal comb present laterally; VII with posteromarginal comb sometimes complete medially; VIII with complete comb. Tergite IX elongate, anterior pair of campaniform sensilla present; tergite X short with longitudinal split incomplete. Sternites II–VII with no discal setae, 5–6 pairs of marginal setae.

Male macroptera. Similar to female but smaller and variable; antennae, pronotum, thorax and abdominal segments I–VI yellow; microtrichia on lateral and posterior margins of tergites II–VII more sparse than female, VIII with complete comb; sternites II–VI with 3 pairs of posteromarginal setae; sternites III-VI each with transversely elongate pore plate.

Related and similar species

The genus Projectothrips comprises nine described Asian species, all of which have antennal segment VIII exceptionally long and slender, and all of which seem to have a specific association with the flowers of Pandanus species. P. beverlyae differs from the other members of the genus in having the metanotum reticulate/striate with markings inside each reticle, instead of linearly striate.
