Additional material examined. A series of specimens of both sexes from Tanzania, Kenya, Uganda, Rwanda, Zambia, Mozambique and South Africa (ANHRT, MWM / ZSM, NHMUK & ZSM).

Remark. The species significantly varies in its size, the forewing width and the size of the black spots on the forewing. The specimens from Gabon (Fig. 12) display minor differences in vesica from the populations in eastern and southern Africa (Figs 13, 14) but clarification of their status requires further molecular studies.

Distribution. Tanzania, Kenya, Uganda, Rwanda, Zambia, Zimbabwe, Mozambique, South Africa (Karisch 2010, 2013) and Gabon (new record).
