( Figs 5 View FIGURES 1–7 , 17, 22 View FIGURES 14–22 , 25 View FIGURES 23–29 )

Female macroptera: Weakly bicoloured; mainly brown, but abdominal segments II–IV yellowish, tube golden; coxae brown, tarsi and fore tibiae yellow, mid and hind femora and tibiae brown with apices yellow; antennal segments I–III yellow, IV–VI brown in apical half, VII–VIII brown; fore wing shaded at base and on distal half.

Head wider than long, without sculpture except near posterior margin; ocellar and lateral postocular setae bluntly pointed, two pairs of minor postocular setae ( Fig. 5 View FIGURES 1–7 ); stylets not retracted into head capsule; antennal segment II with pair of blunt setae at dorsal apex; III with one sensorium also several small transverse ridges near base, IV with 2 stout sensoria, V–VI each with 3 sensoria, VI almost as long as VII+VIII. Pronotum smooth, am setae minute ( Fig. 5 View FIGURES 1–7 ). Mesonotal lateral setae minute. Metanotum with no sculpture medially ( Fig. 17 View FIGURES 14–22 ), two pairs of minor setae on anterior third, one pair of major pointed setae on posterior third. Prosternal basantra weakly developed, mesopresternum slender and transverse; mesoeusternum anterior margin entire; metathoracic sternopleural sutures well-developed. Fore tarsus with small blunt tooth. Fore wing parallel sided, no duplicated cilia. Pelta with slender lateral wings ( Fig. 17 View FIGURES 14–22 ); tergites III–VII each with one pair of sigmoid wing-retaining setae ( Fig. 22 View FIGURES 14–22 ); tergite IX major setae long and finely pointed; tube almost parallel-sided with apex sharply constricted ( Fig. 25 View FIGURES 23–29 ), surface with linear furrows on basal half but reticulate on distal half. Sternites II–III each with median pair of posteromarginal setae longer than length of their sternite.

Measurements (holotype female in microns). Body length 1550. Head, length 100; width 170; ocellar setae 20; lateral postocular setae 30. Pronotum, length 150; width 225; major setae am 5, aa 15, ml 15, epim 40, pa 30. Fore wing length 650. Tergite VI posteroangular setae 40; tergite IX setae S1 120, S2 125, S3 120. Tube length 170. Sternite II marginal setae S1 85; sternite VIII marginal setae S1 45. Antennal segments III–VIII length 45, 40, 50, 55, 30, 25.

Specimen studied: Holotype female macroptera, New South Wales, Cabbage Tree creek, Monga , from dead branch, 7.xii.1996 ( LAM 3066 ).

Comments. This species differs from the other known members of the genus in the shape and larger size of the tube ( Fig. 25 View FIGURES 23–29 ).
