Ozothrips meanjini   sp.n.

( Figs 7 View FIGURES 1‒13 , 19 View FIGURES 14‒22 , 29, 33 View FIGURES 23‒33 )

Female macroptera. Body brown with distal abdominal segments slightly darker but tube golden yellow ( Fig. 7 View FIGURES 1‒13 ); 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 View FIGURES 14‒22 ). 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 View FIGURES 23‒33 ). 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 View FIGURES 23‒33 ); 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 GoogleMaps   . Paratypes: 2 females collected with holotype GoogleMaps   .

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.
