( Figs 19–22 ) Female macroptera . Body and legs yellow, abdominal segment X and posterior third of IX dark brown; antennal segment I white, II–IV pale with II and apex of III and IV variably weakly shaded, V pale with apex light brown, VI–VIII brown; fore wings and major setae pale, but median dorsal setal pair on IX brown. With the character states in the generic diagnosis; antennae 8-segmented, III–IV with sensorium simple. Ocellar setae III 2.0 as long as an ocellus ( Fig. 19 ). Pronotal posteroangular setae longer than antennal segment III; prosternal ferna weakly continuous medially; metanotum with weak longitudinal sculpture ( Fig. 19 ); mesosternal anterior margin with about 12 setae; tergite IX median dorsal setae stout, arising on posterior third of tergite close to posterior setae ( Fig. 20 ), posterior pair I shorter than pair II; X with median split complete; sternite II with 0–3 discal setae, III–VII with 4–10 discal setae sometimes arranged irregularly. Measurements ( holotype female in microns). Body length 1400. Head length 125; width across eyes 125; ocellar setae III 30. Pronotum, length 130; maximum width 160; pa inner setae 45; pa outer setae 45. Fore wing length 650. Metanotal median setae 20. Tergite IX median dorsal setae 60; marginal setae S1 100; S2 125. Tergite X setae S1 115. Antennal segments III–VIII length 40, 35, 35, 47, 8, 10. Male macroptera . Smaller and paler than female; tergite IX with pair of long curved processes ( Fig. 21 ); sternites III–VII with transverse pore plate on antecostal area ( Fig. 22 ). Material studied. Holotype female, Northern Territory , Alice Springs, from Panicum decompositarum lvs., 27.xi.2008 (Chris Palmer). Paratypes : 13 females , 5 males taken with holotype ; Queensland , Moura, 1 female from Cenchrus ciliaris , 20.i.1966 ; Dalby, Broadwater Lake, 1 female , 27.ii.2003 ; 45km south of Tambo, 3 females , 20.v.1999 ; 15km south of Charters Towers, 1 female , 1 male , 2.vii.1995 ; Emerald, 1 female , 29.x.2001 . Western Australia , Kununnura, ii–iv. 2005 . Comments. The females of this species have the median dorsal setae on tergite IX stout, arising in a posterior position and extending well beyond the posterior margin of the tergite. The male has processes on the ninth tergite that are similar to those of A. mnestes , but the sternites bear pore plates. Two females have also been seen from Kununurra in the north of Western Australia that probably represent this species.
