Teuchothrips bundjalong sp.n.

( Figs 17–20 )

Female macroptera. Body and legs brown when mature (holotype slightly teneral), mid and hind tarsi light brown, fore tarsi yellow, fore tibiae with yellow areas; antennal segments I and VIII brown, II yellow on distal half, III–IV mainly yellow, V–VI increasingly light brown on apical half, VII brown with base pale; major setae on head and pronotum pale; fore wings pale on basal half but shaded on distal half. Head longer than wide, genae convex; vertex with weak reticulate sculpture laterally and on posterior third; postocular setae softly pointed to weakly capitate, extending beyond posterior margin of eyes; eyes longer dorsally than ventrally; maxillary stylets close together medially, retracted to level of postocular setae; mouth cone rounded ( Fig. 17 ). Antennal segment III more than twice as long as apical width; IV with 3 small major sense cones, VIII small and distinct from VII. Pronotum transverse, setae am scarcely larger than discal setae, aa and ml setae slightly larger, epim long but pa variable in length; surface with weak sculpture lines. Fore tarsal tooth pointed, at least half as long as width of tarsus, fore femora not enlarged. Fore wing with about 14 duplicated cilia; no more than two sub-basal setae present, one of which is much smaller than the other arising in straight line. Mesonotum transversely reticulate, lateral setal pair minute. Metanotum evenly reticulate, major setal pair slender ( Fig. 18 ). Mesopresternum paired lateral triangles often complete medially, metathoracic sternopleural sutures long. Pelta broadly triangular to D-shaped, base not flared; tergites VI–VIII lateral setae long, tergite IX setae S1 and S2 long and pointed; tube lateral margins straight narrowed distally ( Fig. 19 ) .

Measurements (holotype female in microns). Body length 3150. Head, length 300; maximum width 235. Pronotum, length 250; width 360; epimeral setae 70. Fore wing, length 1190; sub-basal setae S1 5, S2 30, S3 35. Tergite VIII posterolateral setae 110; tergite IX setae S1 240, S2 215; tube, length 280, basal width 105; anal setae, length 225. Antennal segments I–VIII length (width): 60 (45), 60 (40), 95 (40), 90 (40), 80 (40), 70 (35), 60 (25), 40 (15).

Male macroptera. Similar to female in colour and sculpture but smaller; sternite VIII with irregular transverse pore plate on posterior third covering transverse row of discal setae ( Fig. 20 ); tergite IX setae S2 short and stout. Measurements (paratype male in microns). Body length 2910. Head, length 300; width 215. Pronotum, length 260; width 350. Tergite IX setae S1 225, S2 60. Tube, length 280, basal width 100; anal setae, length 230. Specimens studied. Holotype female, New South Wales, Murwillumbah , Crystal Creek , from rolled leaves of Tetrastigma , 24.xii.2006 ( LAM4998 ), in ANIC. Paratypes: 5 females, 5 males and larvae taken with holotype. Comments. Although similar to ater in general appearance and with the stylets quite close together medially ( Fig. 17 ), this species has far shorter setae on the pronotum and head, and the fore wing sub-basal setae are fewer in number.
