Hind part of head red, with white scaly hairs bordering the eyes.
The collar is composed of yellow-brown hairs, with a few black ones intermixed.
Thorax brown, with black pubescence and bristles and yellowish scaly hairs; the pubescence on the sides, the breast, and above the halteres consists of yellow-brown hairs and a few black ones, and a white tuft above the base of the wings.

Illustration of wing:

Description by Hesse:
Easily recognized by the wing-pattern in which the infuscation in marginal cell extends farther apicalwards than in other South African species except dentiferus in which there is however also a projection down the first posterior cell and in which the entire body is reddish and the white scaling across tergite 3 is band-like.
