Teuchothrips garrunggam sp.n.

( Figs 41–43 )

Female macroptera. Body and legs brown, all tarsi yellow also apices of tibiae; antennal segment I and VII–VIII brown, II paler at apex, III yellow but shaded on distal third, IV–VI increasingly brown beyond pale base; major setae pale; fore wings pale, with base weakly shaded. Head longer than wide, genae convex; vertex with extensive reticulate sculpture; postocular setae capitate, extending to mid-point of eyes; maxillary stylets scarcely one-fifth of head width apart, retracted to postocular setae ( Fig. 41 ); mouth cone not elongate. Antennal segment III slightly less than twice as long as apical width; IV with 3 major, stout sense cones, VIII small and distinct from VII ( Fig. 42 ). Pronotum transverse with 5 pairs of capitate major setae; surface with extensive reticulate sculpture. Fore tarsal tooth about one-third as long as width of tarsus, fore femora not enlarged. Fore wing with about 12 duplicated cilia; sub-basal setae long and capitate, S2 arising close to and slightly posterior to S3 ( Fig. 43 ). Mesonotum transversely reticulate, lateral setal pair capitate. Metanotum reticulate, major setal pair slender. Mesopresternum divided into 2 triangles slightly extending medially, metathoracic sternopleural sutures long. Pelta broadly triangular with base strongly flared; tergite IX setae S1 and S2 long, apices weakly capitate; tube lateral margins straight.

Measurements (holotype female in microns). Body length 2360. Head, length 220; maximum width 210. Pronotum, length 165; width 290; epimeral setae 105. Fore wing, length 930; sub-basal setae S1 55, S2 60, S3 60. Tergite VIII posterolateral setae 70; tergite IX setae S1 140, S2 175; tube, length 165, basal width 80; anal setae, length 215. Antennal segments I–VIII length (width): 35 (40), 50 (35), 70 (35), 65 (40), 60 (35), 55 (30), 50 (25), 30 (15).

Male macroptera. Similar to female in colour and sculpture; fore femora enlarged; fore tarsal tooth stout, more than half as long as tarsal width; sternite VIII with broad pore plate across sternite; tergite IX setae S2 similar to S1 setae.

Measurements (paratype male in microns). Body length 2280. Head, length 230; width 190. Pronotum, length 175; width 275. Tergite IX setae S1 150, S2 50. Tube, length 180, basal width 75; anal setae, length 210.

Specimens studied. Holotype female, Queensland, Dalby, Broadwater Lake ,? Geijera , 19.vii.1995 ( LAM 2780 ), in ANIC.

Paratypes: 6 females, 2 males taken with holotype; South Australia, Glenelg [Adelaide] , 1 female, 1 male from Pittosporum phylliraeoides , 1.i.1968 ( LAM 438 ) .

Comments. This species is one of the ater -complex in having the fore wing sub-basal setae S2 close to or even posterior to seta S3 ( Fig. 43 ). The paratype from Adelaide has the major setae on tergite IX more obviously capitate than the specimens from west of Brisbane.
