(Figs 1, 16, 23, 34)
Female macroptera. Body brown, head a little darker at anterior margin, distal abdominal segments darker and tube black; femora extensively yellow but shaded brown on basal half, tibiae darker; antennal segments I–II yellow, III–VIII brown but base of III paler; fore wings uniformly shaded. Head wider than long, postocular setae pointed and longer than eye length; two posterolateral ommatidia larger than remaining facets; maxillary stylets retracted to level of eyes, widely spaced (Fig 16, 23).Antennal segment III with 2 sense cones, IV with 4 straight sense cones; suture between segments VII and VIII present ventrally but not dorsally. Prosternal basantra very weakly sclerotised, ferna transverse, mesopresternum reduced to irregular transverse sclerite medially; metathoracic sternopleural sutures broadly eroded. Metanotum weakly reticulate (Fig 34). Fore wing without duplicated cilia, sub-basal setae very small. Pelta reticulate, transverse, posterior margin concave and separated from anterior margin of tergite II; tergite II eroded laterally; tergites III–VIII with no wing-retaining setae defined, setal pair S4 increasingly short and stout; tergite IX setae S1 and S2 long and fine but slightly shorter than tube; intermediate setae SB1 short and fine, SB2 short and stout, also intermediate setal pair between S2 and S3; setae S3 stout and shorter than S2. Tube scarcely longer than wide (Fig 1).
Measurements (holotype female in microns). Body length 1560. Head, length 140; width 180; postocular setae 65. Pronotum, length 110; width 300; major setae—am 12, aa 30, ml 35, epim 70, pa 40. Fore wing, length 700; longest sub-basal seta 10. Tergite V setae S3 45. Tergite IX setae—S1 140, SB1 35, SB2 50, S2 125, S3 70. Tube, length 150; maximum width 135; width at anal ring 25. Antennal segments III–VII length 55, 45, 42, 42, 65.
Male aptera. Very similar to female in colour and structure; large male with fore femora swollen and meso and metanota more transverse; head without ocelli; metanotal reticulation weak; tergite IX lacking setal pair SB2.
Specimens studied. Holotype female, Australia, Queensland, Capricorn Caves, [S23.165 E150.492], taken by spraying bark and logs, 15.iv.2010 (Monteith & Turco), in ANIC.
Paratypes: 3 females, 1 male taken with holotype; Northern Territory, Darwin, Holmes Jungle, 1 female from curled leaves, 2.i.1996. Darwin, 1 male, 7.x.2006, 1 male from dead wood, 5.v.2014; Coburg Peninsular, 1 female from dead twigs, 4.v.1999.
Comments. The head and antennae of darumbali are closely similar to those of yagara. The tube is similar in shape to that figured by Wang and Tong (2008) for tubullatus from southern China, but the SB2 setae on tergite IX of females are exceptionally stout and considerably more so than in spinurus from Japan (Okajima 1993). The specimens listed from Darwin have the tube very slightly narrower than the holotype but share a similar chaetotaxy. The specific epithet refers to the original people of the Rockhampton area of Queensland.
