Dodonaeathrips eremiae sp. n.

( Figs 172–179 )

Female macroptera. Body brownish yellow to light brown, tergite IX darkest, head with dark post-occipital ridge; legs yellowish brown, tarsi yellow; antennal segment I white, II–VIII light brown; fore wings uniformly but weakly shaded. Head usually without sculpture except on posterior third; ocellar setae short and blunt, pair I close to fore ocellus. Pronotum almost without sculpture, all setae short and blunt. Metascutum reticulate. Fore wing relatively broad; first vein with about 7 setae on basal half, 2 setae distally; second vein with 7–10 setae. Tergites with lateral setae blunt ( Fig. 179 ); tergite X with dorsal split short. Sternite II with 2 pairs of marginal setae but apparently no setae near anterior margin; posterior sternites with short weak microtrichia on transverse lines of sculpture.

Measurements (holotype, in microns). Body length 1100. Head, length 70; width across eyes 135. Pronotum, length 85; maximum width 160. Fore wing, length 640; median width 60; first vein longest seta in basal row 10. Tergite IV S1 setae 7. Tergite IX, MD setae 15; PM S1 setae 55. Tergite X PM S1 setae 45. Antennal segments III–VIII, 32, 30, 35, 37, 10, 15.

Male macroptera. Similar to female; sternite III pore plate thick-walled, internal markings scarcely visible ( Figs 174, 175 ); tergite IX without campaniform sensilla, dorsal setae slender.

Specimens examined. Holotype female macroptera. New South Wales, 80km east of Wilcannia, from Dodonaea ? viscosa leaves, 1.vi.2003 (LAM 4317).

Paratypes: 5 females 1 male taken with a larva and the holotype; New South Wales, 5km east of Cobar, 10 females from Dodonaea ? viscosa leaves, 31.v.2003; Mutawintji, 8 females from Dodonaea ? viscosa leaves, 2.vi.2003; Mutawintji, 1 female from Acacia aneura , 27.xi.1998. Queensland, Windorah, 1 female from Dodonaea ? viscosa leaves, 13.iv.2005. South Australia, 82km north of Maree, 3 females 1 male from Acacia stenophylla , 8.iv.1998; Renmark, 6 females swept, 14.ii.2000.

Comments. Although found on Dodonaea (Sapindaceae) widely across the semi-desert areas of eastern Australia, in more moist areas this thrips is replaced on this host plant by Scirtothrips albomaculatus Bianchi ( Hoddle & Mound, 2003).
