Material examined. Namibia: 1 male, Mahango Game Reserve, (18°16’S, 21°42’E), 2.iii.1992, E. Marais and M. Pusch; 1 male, Nkasa Island, E. Caprivi, S.W.A. (18°27’S, 23°36’E), 3.x.1987, E. Marais (all NMNW).

Description. See Van Stalle (1987: 27 (as Oliarus kibuyanus ).

Distribution. Eastern central Africa: Ruanda, Zaire, Uganda, Kenya, Tanzania. We present the first records from Namibia; here it is obviously restricted to the Caprivi area. Eumecurus kibuyanus belongs to a group of three closely related but geographically separated taxa: E. kibuyanus is known from the East African Highlands, from Ruanda in the north to Lake Mweru in the south, E. chiluvoensis ( Van Stalle, 1987) is recorded from Zimbabwe and Mozambique, and E. pondolandensis ( Van Stalle, 1987) from eastern South Africa. Our specimens, originating from Caprivi, increase the known area of E. kibuyanus considerably towards the south and west. Thus, it is very likely that the transition zone between E. kibuyanus and E. chiluvoensis is the region of the Zambesi river.
