In addition to the abovelisted Equatoria Province records, two localities have been published in the literature and I have seen specimens from the following places: Upper Nile: Malakal (HH). Bahr El Ghazal: Wau (SVS, HH). Blue Nile: Kosti, Wad el Nail near Singa, Wad Medani (all SGC). Blue Nile Districts" (Archibald 1923). Kassala: Suakin (SGC). Kordofan: Delami (SGC). Darfur: Fasher (SVS). Khartoum: Khartoum (SGC, SVS, Gordon College collection, HH). Omdurman (HH). See also Balfour (1906,1907,1908B,1909,1910,1911A, B,C,D,E,G,1912) for spirochete studies on A. persicus from Khartoum. Northern: Dongola (Neumann 1901). Wadi Halfa, Abu Hamed, Atbara, Ed Damer (HH). *In South Africa, called "The Fowl Tampan (Theiler 1952A,B). |
