DISTRIBUTION 



H. droTiiedarii is common wherever camels occur: in southern 

 Russia (Tvirkemnia, southern Tadzhikistan and Uzbekistan)*, and 

 in the Far, x-liddle, and Near East. In Africa, it is found in 

 North Africa, in the transitional belt just south of the great 

 northern deserts, in the eastern and coastal lowlands as far 

 south as the Soraalilands, and in northeastern Kenya. Small in- 

 troduced populations have been found in the Union of South Africa 

 and in Southwest Africa, but whether they now survive is unknown. 

 In some areas, e.g. Anatolia, the camel hyalomma feeds on other 

 hosts since camels are now considerably less common than hereto- 

 fore. The distribution of this species has been mapped by the 

 American Geographical Society (195^). It is of interest to note 

 that within the range of H. dromedarii , from the Eastern Desert 

 of Egypt to Afghanistan, there exists a more localized but highly 

 distinctive parasite of bactrian, or two-humped, camels, H. 

 schulzei Olenev, 1931 (see page 525), which also attacks dromedsu 

 ries. 



*Pomerantzev (1950) lists the synonymous "H. asiaticum " from des- 

 erts and semideserts of southern and eastern Transcavcasia and a 

 considerable part of Kazkhstan. In the south its distribution 

 extends to the boundaries of the Soviet Union, embracing a con- 

 siderable part of Turkmenia, Uzbekstan, and Tadzhiskstan; also 

 Iran and central Asia.
