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.
