HYALOMMA FROMETARII Koch, 184^^. 

 (Figures 162 to I65) 



THE CAl-EL HYALOl^lMA 



NOTE: N-umerous early literature references to "H. aegyptium " 

 apply in whole or part to H. drome darii , but without study of indi- 

 vidual author's material iT is impossible to state the exact spe- 

 cies. In the pre-Delpy period, the name H. dromedarii was fre- 

 quently used for Hyalomma ticks from camels, but the possibility 

 that several species may have been included under this name indi- 

 cates that caution shoiold be exercised before it is assumed that 

 all early references to Hyalomma ticks on camels refer to H. 

 dromedarii . The various "subspecies" of H. dromedarii , now con- 

 sidered invalid, and the few known synonyms of this species are 

 noted below in the section on distribution. No type specimens 

 conforming to present concepts for this species are available 

 (see Feldman-Muhsam 1954-) but since species criteria are now well 

 defined, substitute type specimens should be selected and so 

 designated in an established collection. 



DISTRIBUTION IN THE SUDAN 



Hyalomma dromedarii ranges extensively north of 12°N. lati- 

 tude but is entirely absent in the south of the Sudan. The camel 

 hyalomma has not been previously recorded from the Sudan, but 

 earlier references to H. aegyptium undoubtedly refer in part to 



H. dromedarii . ~ 



Localities from which specimens have been seen (all from 

 camels unless otherwise specified) are: 



Northern ; Ed Damer and Shendi (camels and bulls; SVS). 

 Berber (camels and horses; SVS). Wadi Haifa, Abu Hamed, Atbara, 

 Ed Pamer (camels and cattle; PIH). 



Khartoum ; Khartoum and Omdurman (common on domestic animals, 

 especially camels; SVS, SGC , HH).
