Phaulothrips daguilaris View in CoL sp.n.

( Figs 3, 10 View FIGURES 1 – 10 , 21, 29 View FIGURES 21 – 29 , 30 View FIGURES 30 – 35 )

Macropterous female. Body ( Fig. 21 View FIGURES 21 – 29 ), legs, antennal segments I, II, VI–VIII dark brown, segments III–V light brown with darker apices; major setae mainly pale but shaded at base, postocular cheek setae dark; fore wing weakly shaded with darker area medially.

Head with cheeks straight; anterior margin with pair of pale pre-ocellar setae with shaded bases, extending to apex of antennal II; postocular setae longer than dorsal eye length, arising posterior to inner margins of eyes; maxillary stylets retracted to postocular setae, about one fifth of head width apart. Antennal segments IV–VI very weakly prolonged at ventral apex, VII with longitudinal row of sensoria ( Fig. 3 View FIGURES 1 – 10 ); VIII constricted at base.

Pronotum transverse, reticulate particularly laterally. Fore tarsal tooth recurved, length about half tarsal width. Metanotum reticulate, median setae well-developed. Prosternal basantra small, triangular, lateral to mouth cone; ferna large with median borders almost parallel ( Fig. 30 View FIGURES 30 – 35 ); mesopraesternum transverse.

Pelta with long lateral lobes ( Fig. 10 View FIGURES 1 – 10 ), bearing one pair of setae (in some specimens the setae arise anterior to lobe, or on a separate small sclerite); tergites with reticulate sculpture; III–VI each with one pair of sigmoid wingretaining setae, lateral setal pairs long and blunt; tergite IX setae finely acute, shorter than tube; tube with straight margins weakly constricted near apex ( Fig. 29 View FIGURES 21 – 29 ).

Measurements (holotype female in microns). Body length 7100. Head, length 730; median width 390; preocellar setae 230; postocular setae 260; postocular cheek setae 90. Pronotum, length 280; width 720; major setae—am 35, aa 30, ml 30, epim 310 (260), pa 165. Metanotal median setae 100. Fore wing, length 2380; number of duplicated cilia 20–25. Pelta, length 180; width 730. Tergite IV pair I lateral setae 310. Tergite IX setae S1 720, S2 730. Tube length 1070. Antennal segments III–VIII length 390, 240, 200, 150, 110, 90.

Macropterous male. Similar in colour and structure to female; pronotum and fore femora more robust, fore tarsal tooth twice as long as tarsal width.

Measurements (paratype male in microns). Body length 6900. Head, length 720. Pronotum, length 380; width 820; major setae—am 20, aa 20, epim 280, pa 240. Metascutum, length 330; width 650. Fore wing, length 2300. Tergite IX setae S1 280, S2 300. Tube length 950.

Specimens examined. Holotype female, Queensland, Mt Glorious, from dead branches, 1.xi.2007 (DJT 548). Paratypes; 2 females taken with holotype; Mt Coot-tha, 1 female from dead wood, 17.iv.2011; Yarraman, 1 female from bark sprayed trees, 27.iv.2010; Upper Brookfield, 4 females, 3 males and 1 larva from bark sprayed Eucalyptus , 22.i.2011; Gap Creek Reserve, 1 male from dead wood, 22.iv.2011.

Comments. The tube of this species is longer than in any other member of the genus, the tube/head ratio in females being 1.46–1.67, and in males 1.23–1.31. The pre-ocellar setae are also elongate, and the pelta usually bears a pair of setae. Although apparently associated with Eucalyptus , the actual breeding site of this species is not known.
