Female macroptera. Body colour light brown, legs extensively yellow; antennal segment III yellow, IV–VIII brown; major setae pale; fore wings weakly shaded. Head longer than wide, maxillary stylets slightly less than one-third of head width apart, retracted just anterior to postocular setae, maxillary bridge faint; postocular setae long and capitate. Antennal segment III conical with one small sensorium, IV with two sensoria; segment VIII broad at base (Figure 18). Pronotum with five pairs of long, capitate setae; basantra unusually small; mesopresternum eroded and very slender medially ( Figure 15 ). Mesonotal lateral setae capitate. Metanotum with no sculpture medially, median setae arise on anterior half of sclerite. Fore tarsal tooth minute, scarcely visible. Fore wing with five duplicated cilia, subbasal setae capitate. Pelta relatively large with rounded lateral margins ( Figure 13 ). Tergites II–VII with posteromarginal setae S1 long and capitate; tergite IX setae S1 long and acute; tube short, anal setae long. Measurements of holotype female (in M m). Body length 1700. Head, length 170; median width 130; postocular setae 40. Pronotum, length 120; width 220; major setae am 26, aa 14, ml 36, epim 46, pa 32. Fore wing length 550; sub-basal setae 32, 36, 36. Tergite IX setae S1 100, S2 130, S3 115. Tube length 90; basal width 55; anal setae 170. Antennal segments III–VIII length 36, 42, 40, 38, 38, 18. Material examined Holotype ♀ macroptera: Western Australia , Kununurra Gorge , on dead twig, 23 February 2005 (LAM 4569). Comments The single specimen on which this species is based is presumably teneral, and more mature individuals can be expected to have the body and basal antennal segments darker. However, the species has an unusual group of character states, including the antennal sensorium formula, the minute fore tarsal tooth, and the reduced prosternal sclerites ( Figure 15 ), and would be very difficult to place to genus using the concepts of previous authors.
