Diagnosis

Length 12–14 mm; eyes not hairy; metasomal bands indistinct; clypeus short. Male hair on clypeus and supraclypeal area dorsally directed; mid basitarsus bowed; ventral surface of hind femur without hair. Female tarsal claws simple; metasomal terga without white hair.

Descriptions

Male (AM K.316499), not previously described.— Head width 4.3 mm, body length 12.8 mm. Relative dimensions: HW 50, HL 33, UID 29, UFW 31, LID 36, DMA 32, HVO 4, WOC 11, MOD 4, OOD 9, IAD 11, ASD 3, AOD 7, ML 21, BMW 7, MSL 3.5, SL 12, SW 4, FL c. 57.— Eyes not hairy; face broad, inner orbits strongly divergent ventrally; scapes slightly swollen (width 0.35× length); length malar space c. 0.7× basal width mandible; clypeus short (length 0.35× as long as wide); labrum uniformly convex with slight longitudinal depression medially; middle flagellomeres 1.8× as long as wide. Legs slender; distitarsi rather broad; mid basitarsus slightly bowed and twisted distally; hind tarsus 1.2× as long as hind tibia; length basitarsus 4.9× as long as wide; basitibial area with posterior carina reaching apex. Gonoforceps with long hair (Fig. 30) as in T. orientalis   n.sp.; S7 with very broad, rectangular lateral lobes and short posterior projections (Fig. 50).— Labrum, mandible basally, ventral rim of clypeus, cream; tibiae, tarsi, scape, flagellomeres F1–7 ventrally and half F1 dorsally, orangebrown; trochanters and femora dark brown suffused with variable amounts of orange-brown. T1–6 and S1 with apical margins indistinctly dark brown.— Clypeus with dense, small punctures except narrow basal margin impunctate. Scutum   dull with weak pit-reticulation.— Face with dense, finelybranched, bright orange hair, stiff and obliquely vertically directed on clypeus and supraclypeal area; vertex with tuft of long orange hair behind ocelli; lower gena with dense beard of long white hair. Scutum   with close, long, finely-branched, orange hair; fore basitarsus with fringe of finely-branched white hair. T1,2 with sparse cover of long, erect, finelybranched white hair; remaining terga with simple, semi-erect hair matching underlying integument.

Female (AM K.316500).— Head width 4.55 mm, body length 13.1 mm. Relative dimensions: HW 50, HL 36, UID 27, UFW 31, LID 36, DMA 32, HVO 4, WOC 12, MOD 4, OOD 8, IAD 8, ASD 3, AOD 10, ML 23, BMW 8, MSL 4.5, SL 15, SW 2, FL c. 34.— Eyes not hairy; face broad, inner orbits strongly divergent ventrally; malar space c. 0.6× basal width mandible; clypeus short (length 0.45× as long as wide), uniformly convex transversely; middle flagellomeres c. 1.2× as long as wide; inner hind tibial spur with c. 9 teeth; tarsal claws simple; pygidial plate with strong medial elevation.— Labrum and mandibles brown; legs dark brown with orange-brown suffusions on fore and mid femora, tibiae and all distitarsi.— Clypeus weakly reticulate with open punctures becoming close towards lateral margins. Apical margins T1–4 smoother than remainder of terga.— Face with dense, long, plumose white hair becoming dark brown near vertex. Scutum   with dense, short, plumose, dark brown hair; pre-pygidial fimbria dark-brown or black.

Remarks. Similar to T. latifrons   from which male may be distinguished clypeal hair, mid basitarsus and absence of hair from ventral surface of hind femur. Females may distinguished from T. latifrons   by the tarsal claws and absence of white hair from metasomal terga.

Distribution. Montane areas of eastern Australia from southern Queensland to Victoria (AA, NET, SB, SEH, VM) ( Fig. 86 View Figs 80–91 ).
