Phaulothrips whyallae View in CoL sp.n.

( Figs 9 View FIGURES 1 – 10 , 19 View FIGURES 11 – 20 )

Macropterous female. Body brown to dark brown, tibiae, tarsi and antennal segment III light brown to yellowish; major setae on head and pronotum shaded, setae on posterior tergites pale; fore wing shaded medially but mainly pale in basal and apical quarters.

Head with cheeks almost straight, not strongly elevated medially; two pairs of short pre-ocellar setae present (often dehiscent) ( Fig. 19 View FIGURES 11 – 20 ); postocular setae long, apices blunt; postocular cheek small; one pair of small middorsal setae; maxillary stylets close together medially, retracted to postocular setae. Antennae 8-segmented, VIII constricted at base, IV–VII with apex slightly asymmetric, VII with longitudinal row of small sensoria; III and IV each with two short sensoria.

Pronotum transverse; major setae blunt to weakly capitate. Metanotum reticulate, with one pair of pale median setae. Fore tarsal tooth slightly recurved, with small sub-terminal seta. Prosternal basantra small, triangular, lateral to mouth cone; ferna large, median margins rounded but sub-parallel; mesopraesternum boat-shaped but slender; metathoracic sternopleural sutures long. Fore wing broad, with about 25 duplicated cilia; three sub-basal setae arise in a straight line, seta S3 longest.

Pelta reticulate, tri-lobed with pair of setae on lateral lobes ( Fig. 9 View FIGURES 1 – 10 ); small campaniform sensilla medially; tergites with narrow transverse reticulation, II with minute discal setae anterolaterally; II–VII each with one pair of long setae medially ( Fig. 9 View FIGURES 1 – 10 ), and one pair of weakly sigmoidal wing-retaining setae; III–VII with 2 pairs of long pale setae laterally, on VII twice as long as median length of tergite; setae on IX weakly capitates, shorter than tube.

Measurements, holotype female in microns. Body length 5600. Head, length 750; width across cheeks 420; longest pre-ocellar setae 100; postocular setae 180. Pronotum, length 280; width 620; major setae length am 90, aa 50, ml 160, epim 180, pa 160. Fore wing length 1600. Tergite IX setae S1 380, S2 380. Tube length 670. Antennal segments III–VIII length 430, 240, 190, 120, 110, 100.

Specimens examined. Holotype female macroptera, South Australia, Whyalla, Middleback Station, in old bee nest in Eremophila stem, 16.x.1996 (David Morris 139).

Paratypes: 6 female macropterae, 8 female micropterae, 1 female hemimacroptera, all taken with holotype.
