Anaphothrips whyalla sp. n.

( Figs 158–162 )

Female macroptera. Body light brown, head dark brown, antennal segments I–II dark brown, III-IV largely yellow, V-IX brown, but V slightly paler; wings pale; tergite IX setae shaded. Head wider than long, cheeks almost straight, transversely reticulate behind eyes, ocellar triangle with little or no sculpture; eyes with 6 pigmented facets; ocellar setae III within ocellar triangle, slightly anterior to level of anterior margins of hind ocelli ( Fig. 159 ); postocular setae not transverse, setae I–III along inner and posterior margins of eye. Antennae 9-segmented; II without microtrichia; III–IV slender with weakly rounded margins and small forked sensorium; VI weakly pedicellate, suture between VI–VII transverse ( Fig. 158 ). Pronotum reticulate; posteromarginal setae subequal in size. Metascutal reticulations small medially ( Fig. 160 ); median setae fine and well back from anterior margin; MCS present. Prosternal ferna divided medially. Fore wing first vein with about 10 setae on basal half and 2 or 3 setae on distal half; second vein with 15–17 setae irregularly spaced, 2 setae basal to veinal fork; clavus with 6–7 veinal setae and one basal seta ( Fig. 162 ). Abdominal tergites I–VII with faint transverse sculpture medially, lateral reticulation bearing small microtrichia; VIII posterior margin with no comb medially but a few small microtrichia laterally ( Fig. 161 ), spiracular area small; IX with S1–S2 capitate ( Fig. 161 ); X with longitudinal sculpture lines, S1 capitate. Sternite VII median setae far in front of posterior margin.

Measurements (holotype, in microns). Body length 1600. Head, length 110; width across eyes 150. Pronotum, length 135; maximum width 200. Fore wing, length 780; median width 57; first vein longest seta in basal row 15. Tergite IV S1 setae 7. Tergite IX, MD setae 12; PM S1 setae 75. Tergite X, length 80; PM S1 setae 65. Antennal segments III–IX, 50, 45, 38, 38, 12, 10, 15.

Specimens examined. Holotype female macroptera, South Australia, 14km north of Port Augusta , from Acacia oswaldii , 13.iii.1996 ( LAM 2969 ).

Comments. This species is based on a single specimen, but the capitate major setae on tergites IX and X are unique within this genus ( Fig. 161 ). In most species these major setae are acute, although in both A. parsonsiae and A. westringiae their apices are chisel-shaped.
