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 ).

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