Legs slender; hind tarsus 1.2× as long as hind tibia; hind basitarsus 4.3× as long as wide; posterior carina of basitibial area reaches apex. Genital capsule similar to that for T. orientalis n.sp.

T 1–5 with narrow silver bands stained feruginous across anterior margin.— Clypeus with dense, fine punctures except near ventral rim. Scutum with dull sheen, reticulate with close, small punctures.— Face with dense, pale orange, plumose hair; gena with very dense, plumose, white hair. Scutum with open, long, finely-branched, pale orange-brown hair; fore basitarus with relatively short, tapered plume; anterior margin of hind tibia with open fringe of long, white hair.

Female ( AM K.344659).— Head width 4.20 mm, body length 12.0 mm. Relative dimensions: HW 50, HL 37, UID 31, UFW 32, LID 31, DMA 31, HVO 29, WOC 4, MOD 13, OOD 4, IAD 8, ASD 3, AOD 8, ML 19, BMW 8, MSL 1.0, SL 15, SW 3, FL c. 30.— Eyes hairy; face slightly broader than long, inner orbits gently convergent ventrally; length malar space c. 0.1× basal mandibular width; clypeus shallowly convex, slightly flattened sagittally; gena 0.55× as wide as eye viewed laterally; flagellum short, middle flagellomeres approximately as wide as long; inner hind tibial spur with c. 11 strong teeth; tarsal claws simple; pygidial plate entire, flat.— Labrum, mandible, tarsi (except mid basitarsus), hind tibia, distal ends of femora orange-brown; remainder of legs dark brown. T 1–4 with narrow silver bands, weakly ferruginous across anterior margin.— Clypeus reticulate except along ventral margin, densely punctate. Scutal sculpture as for male.— Face with long, plumose hair, white in lower paraocular areas, becoming orange-brown tipped with dark brown near ocelli, dense in paraocular areas and on frons, open on clypeus and supraclypeal area; gena with close, plumose white hair. Scutum with close, plumose, dark-tipped pale orange hair; hind tibial scopa orange-brown laterally, darker medially; prepygidial fimbria dark brown.

Etymology. The specific name, used as a noun in apposition, is from the Latin for white cheeks.
