Mesandrothrips googongi sp.n.

( Figs 7 , 11, 17 , 21)

Female macroptera. Body and femora brown, tarsi yellow, mid and hind tibiae brown with base paler and apex yellow, fore tibiae brownish yellow; antennal segments I & II brown, III light brown with basal third yellow, IV–VIII light brown; fore wing pale with weak shading sub-medially; major setae all pale. Antennal segment III sub-globose with short basal third ( Fig. 11 ), sense cones short and stout; IV–VII each with distinct pedicel; VIII slender but not sharply narrowed to base. Head almost as wide as long ( Fig. 21 ); vertex without sculpture except laterally and near posterior margin; postocular setae capitate, shorter than dorsal eye length; maxillary stylets wide apart, retracted almost to postocular setae, maxillary bridge well developed. Pronotum wider than long, without sculpture except for median longitudinal apodeme; four pairs of major capitate setae present but am setae not larger than discal setae ( Fig. 21 ). Mesonotum with weak sculpture, lateral setae capitate; metanotum almost without sculpture anteromedially, weakly reticulate posteromedially, median setae small and acute. Fore tarsus with prominent tooth. Fore wing sub-basal setae all capitate; six duplicated cilia present. Mesoprestemum entire. Pelta triangular but with posterolateral comers prominent; tergites II–VII each with two pairs of sigmoid wing-retaining setae, also two pairs of capitate posteroangular setae, except that S2 on VII are finely acute; tergite IX setae S1 capitate, S2 pointed.

Measurements (holotype female in microns). Body length 1730. Head, length 160; width 145; postocular setae 35. Pronotum, length 110; width 200; major setae, aa 35, ml 35, epim 50, pa 40. Fore wing length 720; subbasal setae 35, 35, 50. Tergite IV posteromarginal setae S1 70, S2 35. Tergite IX setae S1 80; S2 90. Tube, length 110; basal width 50. Antennal segments III-VIII length, 40, 42, 40, 38, 38, 26.

Male macroptera. Similar to female in colour, sculpture and structure; tergite IX setae S1 capitate, S2 short and stout; pseudovirga similar to that of many Haplothrips species ( Fig. 17 ).

Measurements (paratype male in microns). Body length 1450. Head, length 160; width 130; postocular setae 25. Tergite IX setae S1 55; S2 30. Tube, length 100; basal width 45.

Material studied. Holotype female, Australia, Australian Capital Territory, Googong Dam , beaten from Acacia sp., 28.ii.1998 ( LAM 3671 ), in ANIC.

Paratypes: 1 female, 1 male taken with holotype; same locality and date , 2 females from Dillwynia sieberi ; same locality , 1 male from Acacia falciformis , 28.iii.1999.

Comments. This species is one of the clavipes group, but is distinguished by the rather shorter third antennal segment ( Fig. 11 ), and the capitate S1 setae on the ninth tergite.
