( Figs 7 , 19 , 29, 33 ) Female macroptera . Body brown with distal abdominal segments slightly darker but tube golden yellow ( Fig. 7 ); legs including tibiae brown with mid and hind femora variably yellow at apex, mid and hind tarsi brown but fore tarsi almost yellow; antennal segment I yellow, II weakly shaded, III yellow on basal half, IV–VIII increasingly brown; fore wings weakly shaded and paler medially; all major setae light brown. Head wider than long, postocular setae pointed and as long as dorsal eye length; eyes slightly prolonged ventrally; maxillary stylets retracted to level of eyes and almost one-third of head width apart ( Fig. 19 ). Antennal segment III with 2 sense cones, IV with 4, all sense cones short and stout; segments VII and VIII fused with no trace of suture ( Fig 29 ). Pronotum smooth, with 5 pairs of long and pointed major setae; notopleural sutures complete. Prosternal basantra bearing one seta, ferna transverse; mesopresternum posterior margin strongly convex and recessed into concave anterior margin of mesoeusternum ( Fig. 33 ); metathoracic sternopleural sutures well-developed. Metanotum weakly reticulate, with pair of long fine setae. Fore wing with about 15 duplicated cilia, with three long pointed sub-basal setae. Pelta reticulate, transverse, close to anterior margin of tergite II; tergites III–VI with setal pair S2 curved or even weakly sigmoid, 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, S2 and S3 long and fine but slightly shorter than tube; intermediate setae SB1 and SB2 short and fine. Tube robust, narrowing distally and sharply constricted to anal ring. Each sternite shorter than corresponding tergite, with posteromarginal setae very small; discal setae minute in regular transverse row. Measurements ( holotype female in microns). Body length 2050. Head, length 175; width 225; postocular setae 65. Pronotum, length 165; width 330; major setae—am 40, aa 35, ml 50, epim 90, pa 75. Fore wing, length 950; sub-basal setae 50, 65, 80. Tergite V setae S3 150. Tergite IX setae—S1 170, SB1 50, SB2 25, S2 160, S3 170. Tube, length 190; maximum width 110; width at anal ring 45. Antennal segments III–VII length 75, 65, 55, 55, 75. Specimens studied . Holotype female, Australia , Queensland , Yarraman , [ S26.857 E151.994 ], collected by insecticide spraying of tree bark, 27.iv.2010 (Monteith)( DJT1116 ) in ANIC . Paratypes : 2 females collected with holotype . Comments . This species is distinguished from the previously described five members of Ozothrips by the enlarged mesopresternum in which the posterior margin protrudes into a deeply concave anterior margin of the mesoeusternum. In contrast, wingless members of this genus have the thoracic sternites largely eroded. The only other member of the genus recorded from Australia , janus Mound & Palmer, has the compound eyes greatly prolonged on the ventral surface of the head ( Mound & Wells 2015 ). The species epithet is derived from an original name for part of southeastern Queensland .
