Holothrips bunyai sp.n.

( Figs 2 , 22 , 25 )

Female macroptera. Body and all femora brown, fore tibiae and tarsi brown, mid and hind tibiae and tarsi yellow; antennal segment I brown, II yellow, III yellow in basal two-thirds ( Fig. 25 ), IV–III brown; fore wings weakly shaded; major setae pale. Head slightly swollen behind large eyes, cheeks weakly concave before widening to posterior margin ( Fig. 2 ); dorsal surface with extensive reticulate areas; postocular setae longer than eye, weakly capitate; maxillary stylets with no loop within prothorax. Antennae 8-segmented, VIII fused to VII with partial suture ventrally. Pronotum transverse, weakly reticulate near anterior and posterior margin, with 5 pairs of slender capitate major setae; fore tarsal tooth about half as long as tarsal width. Prosternal ferna not meeting medially; mesopresternum transverse; metathoracic sternopleural suture long. Mesonotal lateral setae capitate. Metanotum without sculpture medially, median setae small and acute, anterior third with one pair of minor setae ( Fig. 22 ). Fore wing uniformly broad, about 17 duplicated cilia; sub-basal setae long and capitate, arising in a broadly-based triangle. Pelta broad, weakly reticulate ( Fig. 22 ); tergites II–VII with 2 pairs of wing-retaining setae, anterior pair weak on each tergite or absent on VII, major setae capitate; tergite IX setae long and finely acute.

Measurements (holotype female in microns). Body length 3200. Head, length 400; width behind eyes 300; postocular setae 130. Pronotum, length 210; width 420; major setae: am 55, aa 50, ml 55, epim 100, pa 100. Fore wing length 1300; sub-basal setae 55, 70, 100. Tergite IX setae: S1 250, iS 55, S2 280. Tube length 250. Antennal segments III–VI [VII–VIII] length 105, 110, 95, 85, [100].

Material studied. Holotype female macroptera, Queensland, Bunya Mts, Pitta Cottage, from bark spray, 22.xii.2010 (G. Monteith).

Paratypes: 4 females taken with holotype.

Comments. Although similar to oceanicus and speciosissimus in appearance, this species differs in the broader pelta, and the colour of the tube.
