( Figs 14 , 22) Male microptera. Body and femora light brown, with head and tube darkest; antennal segments IV–VIII dark brown, III yellow in basal third and light brown distally, I and II slightly paler than head; tarsi, tibiae and apices of femora yellow; major setae pale. Antennal segment III slender in basal third ( Fig. 14 ), apex angular, with slender sense cones; IV–VII each with distinct pedicel. Head scarcely longer than wide ( Fig. 22 ), vertex with no sculpture; posterior ocelli faintly indicated; postocular setae weakly capitate, longer than dorsal eye length; maxillary stylets wide apart, V-shaped, retracted almost to postocular setae. Pronotum without sculpture lines, anteromarginal setae minute; four pairs of long, weakly capitate major setae. Mesonotum weakly sculptured, lateral setae softly pointed; metanotum without sculpture lines, median setae small and acute. Fore tarsal tooth pointed, longer than half tarsal width ( Fig. 22 ). Fore wing lobe small, with two long setae at apex. Mesopresternum reduced to two small triangles. Pelta small and triangular; tergites II–VII each with 2 pairs of minute wingretaining setae, marginal setae S1 weakly capitate and longer than each of their tergites, setae S2 on VII long and finely acute; tergite IX setae S1 bluntly pointed, S2 shorter and stouter. Sternite VIII without a pore plate. Measurements ( holotype male in microns) Body length 1630. Head, length 150; width 140; postocular setae 65. Pronotum, length 125; with 200; major setae, aa 50, ml 60, epim 65, pa 75. Fore wing lobe 60. Tergite IV posteromarginal setae S1 85, S2 50 . Tergite IX setae, S1 80; S2 35 . Tube, length 100; basal width 55. Antennal segments III–VIII length 50, 50, 45, 40, 35, 30. Female microptera. Larger than male but similar in colour and structure; head with a few sculpture lines laterally, pronotum with weak median longitudinal thickening, but metanotum with no sculpture; mesopresternum continuous but slender medially. Measurements ( paratype female in microns) Body length 2450. Head, length 190; width 170; postocular setae 80. Pronotum, length 175; width 280; major setae, aa 50, ml 80; epim 80, pa 90. Fore wing lobe 75. Tergite IX setae, S1 105, S2 110. Tube, length 135; basal width 70. Antennal segments III–VIII length 70, 70, 60, 60, 50, 35. Material studied . Holotype male, Australia , Queensland , Lamington , O’Reilly’s , in yellow pan trap , vii.2007 (Desley Tree), in ANIC . Paratypes : 1 female in leaf-litter at same locality as holotype; Queensland , Brisbane Forest Park , Mt Glorious , 2 females in Macrozamia leaf-litter, 13.ix.2009 (inANIC) Comments . All four of the available specimens are remarkable for the lack of sculpture on the head, pronotum and metanotum. Each of the three female specimens has the maxillary stylets dissociated.
