Anaphothrips walchae sp. n.

( Figs 150–152 )

Female macroptera. Body colour brownish yellow with brown markings on tergites I–IV, thorax and posterior margin of head; legs yellow with brown shadings; antennal segment I white, II dark brown, III–IX brown; fore wings weakly shaded along veins; major setae at abdomen apex brown. Head wider than long; transverse reticulation behind eyes, weakly sculptured in ocellar triangle; ocellar setae III inside triangle, no further apart than diameter of first ocellus ( Fig. 152 ); eyes with 6 pigmented facets. Antennae 9-segmented; III–IV weakly constricted at apex with forked sensorium; II without microtrichia; VI with short pedicel; suture oblique between VI–VII ( Fig. 150 ). Pronotum with irregular sculpture lines, discal setae setaceous. Metascutum reticulate, median setae well posterior to anterior margin, MCS absent. Fore wing setae short and stout, first vein with about 6–8 setae basally, 2 medially and 2 distally; second vein with about 10 widely spaced setae; clavus with 4–5 veinal setae but no discal setae. Abdominal tergites II–VII with no sculpture medially, lateral sculpture extending just mesad of setae S2; widely spaced sculpture lines bear a few short microtrichia; tergites IV–VI with distance between median setae scarcely greater than the setal lengths; VIII with long regular posteromarginal comb; spiracular area large ( Fig. 151 ).

Measurements (holotype, in microns). Body length 1150. Head, length 75; width across eyes 130. Pronotum, length 100; maximum width 160. Fore wing, length 670; median width 50; first vein longest seta in basal row 12. Tergite IV S1 setae 7. Tergite IX, MD setae 12; PM S1 setae 45. Tergite X PM S1 setae 50. Antennal segments III–IX, 40, 35, 32, 32, 7, 7, 12.

Male macroptera. Similar to female; tergite VIII with two pairs of small thickened setae medially; sternites without pore plates.

Specimens examined. Holotype female macroptera, New South Wales, Walcha, from Ozothamnus diosmifolius leaves ( Asteraceae ), 28.xii.2000 (LAM 3997).

Paratypes: 14 females 3 males and larvae taken with holotype; New South Wales, Chichester , 1 female on Cissus antarctica leaves, 25.xii.2000; Sydney, Castle Hill, NSW Forestry, 5 females from Cassinia sp. , 12.iv.2002. Queensland, Mt Glorious , 1 female from dead wood, 1.xi.2007; Lamington, O’Reilly’s, 3 females from Ozothamnus diosmifolius flowers, 11.x.2006.

Comments. Although similar to A. cecili in general appearance and many details, the males lack sternal pore plates. The major setae on the base of the fore wing first vein, and also the median metascutal setae, are shorter and stouter (very weakly spatulate) than in related species.
