T 1–5 with moderately broad, white bands, distinctly ferruginous across anterior margin; T 7 mid brown.— Clypeus densely punctate except ventral rim impunctate, polished; scutum strongly reticulate, obscuring punctures.— Head densely covered with long, orange hair, erect on clypeus. Scutum closely covered with long, densely-branched pale orangebrown hair; fore basitarsus without plume; hind femur with scattered white hair on anterior margin.

T. pulcherrimus T. dives trochanters and basal half of femora dark brown. T 1–4 with moderately wide, white bands distinctly ferruginous across anterior margins; wings darkened.— Surface of clypeus polished with very broad irregular depressions, dulled basally with pit-reticulation; labrum with longitudinal medial carina and weak, oblique rugae laterally.— Apico-lateral corners of clypeus, paraocular areas and frons densely covered with golden-brown, plumose hair. Scutum closely covered with densely-branched, pale orange-brown hair tipped with dark brown; prepygidial fimbria chocolate brown; hind tibial scopa pale orange.
Remarks. This species is referred to as F265/M 236 in Houston (2000).
