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.

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.
