( Figs 4 , 15 , 25 , 35 ) Female macroptera . Body brown with distal abdominal segments darker and tube black; legs brown with mid and hind femora variably yellow distally and ventrally; antennal segments I–III mainly yellow with III shaded in apical half, IV–VIII increasingly brown; fore wings strongly shaded with darker longitudinal line. Head wider than long, postocular setae pointed and longer than eye length; maxillary stylets retracted to level of eyes, widely spaced ( Fig. 15 ). Antennal segment III with 2 sense cones, IV with 4, all sense cones curved, the ventral pair on IV being strongly curved; suture between segments VII and VIII present ventrally but not dorsally ( Fig 25 ). Pronotum smooth, with 5 pairs of major setae, am setae smallest, epim setae long; notopleural sutures complete. Prosternal basantra weakly sclerotised but usually bearing one seta, ferna transverse, mesopresternum reduced to irregular median sclerite; metathoracic sternopleural sutures broadly eroded. Metanotum very weakly reticulate. Fore wing without duplicated cilia, one sub-basal seta elongate. Pelta reticulate, transverse, close to anterior margin of tergite II but variably eroded postero-medially ( Fig. 35 ); tergites II‒VII with no wing-retaining setae defined, setal pair S3 very long and fine, much longer than posteroangular pair S4; tergite VIII setal pair S1 long and fine, S3 short and slightly stout; tergite IX setae S1 and S2 long and fine and slightly longer than tube, S3 shorter; intermediate setae SB1 short and fine, SB2 half as long as S1. Tube bee-hive shaped, sharply constricted to anal ring ( Fig 4 ). Measurements ( holotype female in microns). Body length 1800. Head, length 155; width 200; postocular setae 90. Pronotum, length 115; width 285; major setae—am 20, aa 25, ml 35, epim 85, pa 65. Fore wing, length 750; longest sub-basal seta 95. Tergite V setae S3 110. Tergite IX setae—S1 200, SB1 35, SB2 15, S2 220, S3 175. Tube, length 220; maximum width 160; width at anal ring 30. Antennal segments III–VII length 55, 50, 50, 45, 70. Male aptera . Very similar to female in colour and structure, meso and metanota more transverse; head without ocelli; metanotal reticulation weak; tergal setae S1, S2 and S3 long and fine; tergite IX lacking setal pair SB2. Specimens studied . Holotype female, Australia , Queensland , Darnley Island [ S9.5797 , E143.7790 ], from dead twigs, 17.xi.2009 ( LAM5293 ), in ANIC . Paratypes : 4 females taken with holotype ; Cairns, James Cook University [ S16.814 E 145.685 ], 2 females , 1 male from dead branches, 3.xi.2008 . Comments . This species is closely similar to nogutii Kurosawa but has the tube distinctly more robust ( Fig. 4 ). Erub is an original name for Darnley Island.
