Diagnosis

Eyes hairy; metasomal bands narrow, silver. Male mid tibia with extensive areas of dark brown; fore basitarsus with distinct plume; S7 with narrow, rectangular lateral lobes. Female clypeus transversely convex, not flattened, with a straight basal margin; inner hind tibial spur with c. 9 teeth.

Variation

Both sexes sometimes have metasomal bands of moderate width and occasionally the bands are gold.

Descriptions

Male (holotype).— Head width 3.70 mm, body length 10.7 mm. Relative dimensions: HW 50, HL 39, UID 29, UFW 30, LID 29, DMA 31, HVO 4, WOC 13, MOD 4, OOD 9, IAD 9, ASD 3, AOD 7, ML 19, BMW 7, MSL 1.8, SL 13, SW 3, FL c. 50.— Eyes hairy; face narrow, inner orbits parallel; length malar space c. 0.25× basal mandibular width; flagellum as long as head width; middle flagellomeres c. 1.5× as long as wide; hind tarsus as long as hind tibia; hind basitarsus 4.5× as long as wide; hind basitibial area carinate on posterior side only. Gonoforceps with long hair (Fig. 37); S7 with narrow, rectangular lateral lobes and strong posterior projections ( Fig. 70 View Figs 68–79 ).— Scape, labrum, mandible medially, tarsi, tibiae and distal ends of femora orange-brown, fore and mid tibiae medially suffused with dark brown; flagellum dark brown dorsally, mid brown ventrally. T 1–5 with bands usually narrow, silver, sometimes of moderate width and occasionally gold.— Clypeus, excluding apex, densely punctate; scutum   with dull sheen, pit-reticulate, close fine punctures.— Face densely and scutum   closely covered with long, finely-branched, bright orange hair. Fore basitarsus with tapered plume of golden hair; femora and trochanters with much long pale hair.

Female ( AM K.334760).— Head width 4.10 mm, body length 11.6 mm. Relative dimensions: HW 50, HL 37, UID 28, UFW 30, LID 30, DMA 31, HVO 5, WOC 13, MOD 4, OOD 8, IAD 8, ASD 3, AOD 9, ML 24, BMW 8, MSL 1.0, SL 15, SW 3, FL c. 33.— Eyes hairy; face slightly wider than long, inner orbits parallel; length malar space c. 0.2× basal mandibular width; clypeus transversely convex, basal suture horizontal, not bowed; flagellum shorter than head width, F1 1.6× as long as wide, F2–9 c. 1.2× as long as wide; inner hind tibial spur with c. 9 teeth; pygidial plate minutely emarginate, strongly elevated medially.— Labrum orangebrown; mandible medially amber; trochanters and femora dark brown; remainder of legs mid-brown. T 1–4 with narrow silver, occasionally gold, bands.— Clypeus and supraclypeal area reticulate, densely punctate, scutum   reticulate, weakly shining with close fine punctures.— Head with white to pale orange, plumose hair, dense in paraocular areas and on frons, open on clypeus and supraclypeal area. Scutum   closely covered with very short, plumose, dull orange-brown hair; scopa brown; prepygidial fimbria brown.

Remarks. This species has commonly been misidentified in collections as T. venustus   and the specimen used as the model for figs 198–200 in Michener (1965) was probably T. orientalis   n.sp.

There are a number of sympatric species that are similar in appearance. Males may be distinguished from T. venustus   by the extensive areas of dark brown on mid tibia and the shape of S7; from T. aeratus   n.sp. by the presence of a plume on fore basitarsus; from T. fuscus   n.sp. by paler colour and the shape of S7 and from T. tenuiculus   by the shape of S7. Females may be distinguished from T. venustus   by the narrow metasomal bands and straight basal margin of the clypeus; from T. aeratus   n.sp. by unflattened clypeus; from T. fuscus   n.sp. by the paler colour and number of teeth on inner hind tibial spur and from T. tenuiculus   by the length of F1 and the number of teeth on inner hind tibial spur.

Distribution. Eastern Australia between Brisbane and Adelaide (BBS, CP, FLB, KAN, NET, NNC, NSS, SB, SCP, SEC, SEH, SEQ, VM) ( Fig. 109 View Figs 104–115 ).

Etymology. The specific name is a Latin adjective meaning eastern, referring to the distribution of this species.
