DISTRIBUTION IN THE SUDAN
According to King (1926), R. sanguineus "occurs throughout the country but is relatively scarce in # south ...... this is the common dog tick of the northern and central Provinces". This statement agrees with the present observations. Although the kennel tick may be very common locally on dogs in Equatoria Province, it is also frequently absent or rare in this Province. Its occurrence and numbers on wild animals is equally as erratic as on domestic dogs. Reasons for this variability of abundance are poorly understood and suggest an interesting topic for local investigation.
Localities, hosts, and sources of specimens that have been examined are the following:
Bahr El Ghazal: "Northern t of Province" (Dog; SVS). Fanjak (cattle and dogs; SWS, HH). Galual-Nyang Forest (dogs, hedgehogs, and hares; SVS, HH). Near Kordofan border (greater bustard; SVS). Kenisa (baboon; BM(NH)). Near Yirol (domestic dogs; SVS).
Upper Nile: Makier (cattle; SVS). Malakal (sheep, goats, and dogs; fairly common on cattle; SVS, HH). Melut (man; SGC). Akobo Post (lion; SGC). Bor (dogs and horse; SGC). (sheep and lesser bustard; SVS). Ler (dogs; SVS).
Blue Nile: Wad Medani (cattle, sheep, dogs, goats, and horses; SGC, H. Herpestes ichneumon and large vulture; SGC). Hodft and Hosh (hedgehogs'; SEC).TSinga (camels; SGC).
Kordofan: Heiban (hedgehogs; SGC). Jebel Tabuli (kudu, SGC). El Obeid (cattle; SVS). Koalib Hills (fox and bustard, Lissotis melanogaster; SGC). Tabanga (domestic pigs; SGC). Delami (hare and # SGC). "Western Kordofan" (sheep; SVS).
Darfur: Radom (cattle; SVS). Sibdo (horse; SWS). Muhagariya (sheep; SVS). Zalingei (donkey; SVS). Kulme (Vulpes ida; BMNH). Fasher (dog and goat; SVS). Nyala (dog; SVS). les north of Safaha (sheep; SWS).
Khartoum: Khartoum (dogs; Balfour 1911F. Kite, secretary # in Zoo, "dog, and fox; SGC. Sheep, camels, horses, and goats; HH).
Kassala: Sinkat (hare; BMNH. Dogs; SVS). Port Sudan (dogs; SWS, BMNH. As R. macropis: Schulze 1936. Donkeys; SVS). Kassala (dogs, sheep, horses, goats, and camels; SVS). Tokar (dogs; SVS).
Northern: Wadi Halfa and Atbara (dogs; SGC, HH). Abu Hamed (fox, hare, dogs, and camels; HH). Jebel Barkal (fox; Sudan National
Although R. S ineus was first described from France and
authors have shown considerable hesitancy over considering this a typically African tick, there is no apparent reason for not doing so. The genus Rhipicephalus is well established as a tightlybound group with # as its center of dispersal. The species # is so typical of the genus that it is assumed that
s is an African tick whose predilection for domestic dogs and possibly for birds has facilitated its spread throughout the warmer parts of the world.
Cooley (1946) states that R. sanguineus is probably the most widely distributed tick species in the world. With the possible exception of the fowl argas, Argas persicus, this is undoubtedly true. The kennel tick now inhabits practically all countries between 50°N. and about 35°S. and is known frequently to spread rapidly once it becomes established in a new area.
