description: Hoplandrothrips coorongi sp.n.
(Figs 7, 9)
Male macroptera. Body and legs brown, hind tarsi slightly paler, fore tarsi yellow; antennal segments III–V yellow at base; all major setae pale; fore wings pale, weakly shaded medially.
Head weakly reticulate dorsally, with no long setae ventrally; cheeks convex, with one pair of stout setae in basal third; maxillary stylets retracted to eyes, close together medially (Fig. 9); postocular setae capitate, wide apart; mouth cone short and pointed. Antennae 8-segmented; III with prominent ring-like ridge near base (Fig. 7), III with 3 sensoria, IV with 4 sensoria; VII pedicellate, VIII broad at base.
Pronotum without sculpture, strong median longitudinal apodeme; major setae capitate, except aa setae no larger than discal setae; basantra absent; mesopresternum formed of two lateral triangles. Fore femora large, inner apex without tubercles; fore tibiae stout; fore tarsal tooth as long as tarsal width. Mesonotal lateral setae small, capitate. Metanotum weakly reticulate with pair of weak longitudinal ridges, median setae acute and arising on anterior third of sclerite, with 2 pairs of minor setae anteromedially. Fore wings parallel sided, sub-basal setae S1 and S2 capitate, S3 slender and acute; with 13 duplicated cilia.
Pelta broadly triangular; tergites II–VII with 2 pairs of wing retaining setae, also 3–4 pairs of lateral discal setae arranged in a line, lateral setae S1 and S2 capitate to broadly spoon-shaped; tergite IX setae S1 and S2 capitate, intermediate seta 0.5 as long as S2. Sternite III–VI with paired reticulate areas laterally; VIII with broadly transverse pore plate.
Measurements (holotype male in microns). Body length 2400. Head, length 250; width across cheeks 225; postocular setae 60. Pronotum, length 200; width 320; major setae—am 5, aa 55, ml 30, epim 55, pa 30. Fore wing, length 900; sub-basal setae 35, 35, 50. Tergite IX setae, S1 70; S2 50; S3 135. Tube length 150. Antennal segments III–VIII length 80, 70, 60, 30, 40, 35.
Female macroptera. Similar to male in colour, but differing in structure as follows: head with postocular setae capitate but not reaching posterior margin or eyes; pronotum reticulate, am setae similar to aa and pa setae; mesopresternum complete transverse; abdominal sternites without paired reticulate areas.
Measurements (paratype female in microns). Body length 2350. Head, length 250; width across cheeks 225; postocular setae 15. Pronotum, length 160; width 280; major setae—am 20, aa 20, ml 30, epim 55, pa 25. Tergite IX setae, S1 55; S2 70; S3 135. Tube length 150.
Specimens examined. Holotype male macroptera, South Australia, Salt Creek 15km south of Coorong, from dead Eucalyptus branches, 11.iii.2011 (LAM 5460).
Paratype female, taken with holotype.
Comments. Although sharing several character states with hylaius and xanthocnemis, this species has a remarkable ring-like structure at the base of the third antennal segment, and the postocular setae of the female are exceptionally short.
