DISTRIBUTION 



H. detritum is an Asiatic tick that ranges from Manchuria 

 through China and India, much of southern Russia, southeastern 

 Europe, and the Middle East; into Asia Minor, the Near East, 

 the Mediterranean littoral of Africa westwards to Algeria; and 

 into northcentral Sudan, where it occiirs only in small, localized 

 populations. It also occurs in Spain, probably having been intro- 

 duced from northwestern Africa. 



In Egypt and apparently in Libya, H. detritum is consider- 

 ably less common than it is to the west~in Algeria and in Near 

 Eastern countries. This distributional pattern is common for 

 animal groups that have invaded North Africa from the east. 



NOTE: Specimens referred to this species by Rageau (1951) 

 from the Cameroons were later determined by him (1953) as H. 

 trvmcatum (= H. transiens ). ~
