Description by Hesse: https://www.biodiversitylibrary.org/page/40845034#page/661/mode/1up
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.

Distribution: Botswana, Malawi, Mozambique, South Africa ("Transvaal"), Tanzania, Zimbabwe
