DISTRIBUTION 



Although R. sanguineus was first described from France and 

 authors have sEown considerable hesitancy over considering this 

 a typically African tick, there is no apparent reason for not doing 

 so. The genus Rhipicephalus is veil established as a tightly- 

 bound group with Africa as its center of dispersal. The species 

 sanguineus is so typical of the genus that it is assumed that 

 this 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 (194-6) 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 freq-uently to spread 

 rapidly once it becomes established in a new area.
