Holothrips lamingtoni sp.n.

( Figs 7 , 28 )

Female macroptera. Body bicoloured, mainly yellowish brown, mesothorax brown also metathorax laterally, tergite I yellow, II–VII brown on anterior thirds but yellow on posterior margins, VIII–IX yellow, tube golden but almost yellow on distal fifth before grey apex; antennal segments I–III concolourous with head, IV–VIII increasingly brown ( Fig. 28 ); mid and hind femora brown with tibiae and tarsi sharply yellow; fore legs uniformly light brown; antennae shading from yellow at base to brown at apex; fore wing weakly shaded; all major setae light brown. Head with cheeks slightly swollen behind eyes then weakly concave to almost straight ( Fig. 7 ); dorsal surface reticulate posterolaterally, with almost no sculpture medially; postocular setae long and acute; maxillary stylets retracted to eyes, close together medially but wider apart at level of pronotum. Antennae 8-segmented, VIII fused to VII with suture variably developed ventrally. Pronotum transverse, weakly sculptured on anterior and posterior thirds, with 5 pairs of pointed major setae, notopleural sutures complete; fore tarsal tooth about half as long as tarsal width. Prosternal ferna not meeting medially; mesopresternum transverse, mesoeusternal anterior margin entire; metathoracic sternopleural sutures long and slender. Mesonotal lateral setae well-developed. Metanotum without sculpture medially, major setae small arising medially, anterior third with one or two pairs of minor setae. Fore wing uniformly broad, about 26 duplicated cilia; sub-basal setae S1 and S2 weakly capitate, S3 long and acute, arising almost in a straight line. Pelta reticulate, elongate with small lateral wings; tergites II–VI with two pairs of wing-retaining setae, these setae very small on VII, major setae long and finely pointed; tergite IX setae long and finely acute; tube shorter than head.

Measurements (holotype female in microns). Body length 4400. Head, length 500; width behind eyes 350; postocular setae 175. Pronotum, length 200; width 500; major setae: am 75, aa 75, ml 130, epim 150, pa 175. Fore wing length 1700; sub-basal setae 100, 130, 200. Tergite IX setae: S1 325, iS 100, S2 300. Tube length 380. Antennal segments III–VI [VII–VIII] length 160, 155, 125, 100, [110].

Male macroptera. Similar to female except, fore tarsal tooth slightly more robust; sternites V–VI (rarely IV) with variable areas of reticulate sculpture.

Measurements (paratype male in microns). Body length 4000. Tergite IX setae S1 300, iS 75, S2 85.

Material studied. Holotype female, Queensland, Lamington, O’Reilly’s , from Lophostemon confertus dead leaves and nuts, 13.iii.2007 ( DJT 431 ).

Paratypes: Queensland, at same locality as holotype, 6 females, 6 males from dead branches and leaves of Lophostemon and Nothofagus , 13–14.iii.2007 ; at same site, 3 females, 9–11.x.2006. Brisbane, Mt Glorious , 1 female, 19.i.2006 , 2 males, 9.iii.2006 , 1 female, 22.iii.2007, 2 females, 2.viii.2008; Brisbane Forest Park, 1 female, 1 male, 10.iii.2006 ; Springbrook , 1 female, 2 males, 29.xi.2011 ; Mt Mitchell , 3 females, 2 males 27.ii.2011 ; Eungella N.P., 1 female, 1 male, 27.xi.2009 . Tasmania, Huon Valley , 1 female, 31.i.2001 , Picton Valley , 1 female, 29.v.2001 . New South Wales, Lilyvale , 1 female, 4.ii.1910 .

Comments. This species is readily distinguished from the other members of the genus in Australia by the bicoloured tergites on each of which the posterior third is sharply yellow.
