Hoplandrothrips tareei sp.n.

( Figs 29, 30 )

Male macroptera. Body and legs mainly brown; fore tibiae and all tarsi yellow; abdominal tergites II–VII with inconspicuous pale area anterolaterally; antennal segment III brownish yellow with base paler, IV–V yellow at base; major setae pale; fore wing faintly shaded medially with apex pale.

Head longer than wide; cheeks narrowing to basal constriction; weakly reticulate dorsally, ventral surface with only one pair of long setae; cheeks with several pairs of weak setae; postocular setae arising laterally, longer than eye width; maxillary stylets retracted anterior to postocular setae, close together medially ( Fig. 29 ); mouth cone short and bluntly pointed. Antennal segment III with 3 sensoria, IV with 3 stout sensoria; VII clearly pedicellate, VIII broad to base.

Pronotum weakly reticulate only near posterior margin, with median longitudinal apodeme; 4 pairs of major setae long and capitate, am setae no longer than discal setae. Fore femora stout, without tubercles, fore tarsal tooth stout. Basantra absent, chitinous islets large; mesopresternum comprising paired lateral triangles and a median area; mesoeusternal anterior margin slightly narrowed. Mesonotal lateral setae short and capitate. Metanotum weakly reticulate at anterior but more strongly so on posterior half; median setae finely acute on anterior half of sclerite ( Fig. 30 ). Fore wing almost parallel-sided; sub-basal setae S1 and S2 capitate, S3 acute; 9–11 duplicated cilia.

Pelta broadly bell-shaped ( Fig. 30 ); tergites II–VII with 2 pairs of large wing retaining setae; one pair of small setae near campaniform sensilla medially; lateral setae S1 on II–IX long, apices capitate and weakly fringed; S2 on IX blunt; sternal reticulate areas very faintly indicated anterolateral to discal setae, VIII with slender transverse pore plate.

Measurements (holotype male in microns). Body length 1850. Head, length 210; width 180; po setae 60. Pronotal major setae, am 5, aa 55, ml 30, epim 55, pa 40. Fore wing length 700. Tergite IX setae: S1 90; S2 50; S3 90. Tube length 110. Antennal segments III–VIII length 55, 55, 55, 45, 40, 30.

Female macroptera. Similar to male in colour and general structure; head less constricted to base, postocular setae shorter than eye width. Pronotal am setae capitate; mesoeusternum anterior margin broader than in male, mesopresternum comprising three sclerites. Tergites III–IX with setae S1 and S2 capitate and weakly fringed.

Measurements (paratype female in microns). Body length 2050. Head, length 250; width 215; po setae 45. Pronotal major setae, am 25, aa 45, ml 40, epim 60, pa 35. Fore wing length 750. Tergite IX setae: S1 90; S2 110; S3 120. Tube length 140. Antennal segments III–VIII length 65, 60, 60, 50, 40, 30.

Specimens examined. Holotype male. New South Wales, Lorien, Lansdowne, near Taree, from Ficus coronata , 13.iv.2002 (LAM4134).

Paratypes: New South Wales, 1 female from same site as holotype, 18.x.2001; 1 female from Kiwarrak, near Taree, 29.x.2001. Queensland, Red Cedar, 15km west of Mt Glorious, 1 male from Ficus coronata , 13.x.2006.

Comments. The holotype male is a rather small individual, and large males of this species can be expected to look rather different. It is an unusual species in having only three sensoria on the fourth antennal segment.
