Holothrips notialis View in CoL sp.n.

( Figs 8 View FIGURES 1–9 , 16 View FIGURES 10–16 , 23, 24 View FIGURES 17–24 )

Female macroptera. Body, legs and antennae brown, antennal segment III yellow at extreme base, tube golden brown; fore wings shaded; major setae pale. Head slightly swollen behind large eyes, cheeks weakly concave before widening to posterior margin ( Fig. 8 View FIGURES 1–9 ); dorsal surface extensively reticulate except in ocellar region; postocular setae long and acute, postocellar setae shorter than one hind ocellus; maxillary stylets with small loop at level of prothorax. Antennae 8-segmented, VIII fused to VII with variable ventral suture. Pronotum transverse, reticulate at anterior and posterior margins, with 5 pairs of slender pointed major setae; fore tarsal tooth about half as long as tarsal width. Prosternal ferna not meeting medially; mesopresternum transverse; metathoracic sternopleural sutures long. Mesonotal lateral setae capitate. Metanotum weakly reticulate medially, median setae small and acute, anterior third with 2–4 minor setae. Fore wing uniformly broad, 12–14 duplicated cilia; sub-basal setae bluntly pointed to finely acute, arising almost in straight line. Pelta elongate, irregularly triangular, weakly reticulate ( Figs 23, 24 View FIGURES 17–24 ); tergites II–VII with 2 pairs of wing-retaining setae, anterior pair weak on each tergite, both pairs small and straight on VII, major setae finely acute; tergite IX setae long and finely acute, iS setae often duplicated ( Fig. 16 View FIGURES 10–16 ); tube slightly constricted beyond widened base, and more sharply constricted at apex ( Fig. 16 View FIGURES 10–16 ).

Measurements (holotype female in microns). Body length 3300. Head, length 400; width behind eyes 300; postocular setae 130. Pronotum, length 175; width 450; major setae: am 50, aa 85, ml 100, epim 140, pa 150. Fore wing length 1300; sub-basal setae 75, 105, 150. Tergite IX setae: S1 275, iS 75, S2 280. Tube length 280. Antennal segments III–VI [VII–VIII] length 120, 110, 95, 85, [100].

Male macroptera. Variable in size, small male similar to female, large male with fore tarsal tooth as long as tarsal width, fore femora swollen, pronotum robust with strong median apodeme; sternites IV–VII with areas of reticulate sculpture, tergite IX setae S2 stout.

Measurements (paratype male in microns). Body length 3100. Tergite IX setae S1 275, iS 75, S2 85.

Material studied. Holotype female macroptera, New South Wales: Talaganda, Lowden Forest Park, from Eucalyptus dead nuts, 27.ii.2011 ( DJT 1184 ).

Paratypes (all macropterae): 6 females, 6 males taken with holotype. Australian Capital Territory, Namadji , 2 females from dead Eucalyptus , x.2010 . South Australia, Adelaide, Stirling , 3 females, 3 males from Eucalyptus dead nuts, 8.iv.2004 ; Adelaide Hills, Wotton Scrub , 1 female, 1 male, 10.i.2006 ; Coorong to Kingston , 2 females, 1 male from Eucalyptus dead branches, 11.iii.2011 . Victoria, Nelson , 1 male from dead Eucalyptus nuts, 5.x.2013 . Tasmania, 17 Mile Plain , 1 female, 1 male from Eucalyptus obliqua dead leaves, 12.iii.2010 ; Lake Pedder , 1 female, iii.2004 .

Comments. This appears to be the southern counterpart of the northern species federicae . In both of them the body, legs and antennae are uniformly brown, but the setae are long and pointed and the tube is a different shape ( Figs 15, 16 View FIGURES 10–16 ).
