1955). Aside from this, Colobus monkeys, also knovm as gtiereza 

 or leaf-eating monkeys, are the only knovn hosts. As stated 

 below, eill other records from different mammals, incliiding man 

 and monkeys other than Colobus refer to vtndescribed Ixodes spe- 

 cies or subspecies. 



Colobus polykomos caudatus (Neumann 1901,190X,1910B. Nuttall 

 and Warburton 1911 j" C . polykomos dodingae (Sudan record above), 

 Colobus sp. (Nuttall 1^1677"^ 



Anderson (1924B) recorded Rattus rattus kLjabius as a host 

 in Kenya. Specimens of this tick species collected by Anderson 

 in Kenya, now in British Museum (Natural History) collections, are 

 labelled as from Colobus monkeys and others bear no host data 

 (Arthur, ms.). The rodent host is believed to be an error, 



Lewis (1931c ) listed this tick from a duiker, bushbuck, and 

 domestic cattle in Kenya. These four collections, two from bush- 

 bucks and one each from the other hosts have been examined at 

 British MuseTxm (Natioral History) and found to refer to an entirely 

 different species. They were then referred to Dr. Arthtir, who 

 considers them to be an undescribed subspecies of Ixodes pilosus 

 (Arthur, ms.), 



Rageau (1953B) reported specimens from man and from another 

 kind of monkey, Cercopithecus (= Lasiopyga ) cephus cephus. These 

 represent an undescribed species related to Ixodes scnillingsi 

 (Arthur, ms.). 



BIOLOGY 



This species is a parasite of Colobus monkeys and uncommonly 

 of man. It is said to prefer young hosts and attaches exclusively 

 to the eye according to collecting notes furnished Nexomann (1901), 

 Females have been taken from around the eyes and ears and in the 

 axillae of eidult Colobus monkeys in Kenya and on the eyelid of a 

 Colobus monkey in the Sudan. 



The male has been found only in copula on the host (and once 

 alone on a tree trunk) and its feeding nabits are not known. Lar- 

 vae, nymphs and both sexes of adults may occur on the same host 

 (Arthur, ms.),
