Anaphothrips westringiae sp. n.

( Figs 153–157 )

Female macroptera. Body and legs yellow, tergites II–VI with pair of brown areas anterolaterally; antennal segment I white, II–IX brown but III–IV slightly paler; major setae on abdominal tergites IX–X dark; fore wings weakly shaded. Head wider than long, reticulate behind eyes but no sculpture in ocellar triangle; eyes with 6 pigmented facets; ocellar setae III on anterior margins of triangle ( Fig. 155 ). Antennae 9-segmented, III–IV with small forked sensorium; segment VI short; II without microtrichia; VI narrowed to base but not pedicellate ( Fig. 153 ). Pronotum with irregular sculpture lines ( Fig. 155 ). Metascutum irregularly reticulate, median setae not at anterior margin; MCS absent ( Fig. 154 ). Fore wing setae small, first vein with about 9 setae basally, 2 medially and 2 distally; second vein with 8–9 setae; clavus with 6 veinal but no discal setae. Abdominal tergites III–VI with no sculpture medially; lateral sculpture lines not extending mesad of setae S2; lateral lines with dentate microtrichia, extending mesad on VII–VIII ( Fig. 156 ); posteromarginal comb on VIII with about 10 short fine microtrichia medially but usually none laterally; spiracles slightly enlarged; X with complete dorsal split; major setae on IX–X stout with chisel-shaped apices. Sternites with dentate microtrichia laterally on sculpture lines.

Measurements (holotype, in microns). Body length 1100. Head, length 90; width across eyes 135. Pronotum, length 110; maximum width 160. Fore wing, length 500; median width 40; first vein longest seta in basal row 7. Tergite IV S1 setae 7. Tergite IX, MD setae 5; PM S1 setae 55. Tergite X PM S1 setae 55. Antennal segments III–IX, 40, 35, 35, 22, 10, 7, 12.

Male macroptera. Similar to but smaller than female; tergite IX with 2 pairs of short stout setae medially; sternites III–VII with small C-shaped pore plate, reduced to a curve on VII ( Fig. 157 ).

Specimens examined. Holotype female macroptera, Australian Capital Territory, Canberra, Black Mtn, from leaves of cultivated Westringia fruticosa (Lamiaceae) , 5.ii.2007 (LAM).

Paratypes: 9 females 5 males taken with holotype and larvae.

Comments. The plant species from which this thrips was collected has a natural distribution along the eastern coast of Australia, but is also widely cultivated as a garden plant. This thrips species has the posteromarginal comb on tergite VIII similar to that of A. geleznowiae , but that Western Australian species has the metascutal campaniform sensilla present, long setaceous setae on tergite IX of females, and males with large C-shaped pore plates. Moreover, antennal segment VI is unusually short in A. westringiae .
