THE CMTRAL AFRICM HIGHLAND BROWN TICK 



N Q c? EQUATORm PROVINCE RECORDS 



The Nagichot specimens, from a cow at 65OO feet elevation in 

 the Didinga Mountains, were collected by l^r. H. B, Luxmoore in 

 1951. The British Museum (Natiiral History) specimens, found un- 

 identified in their collections, were taken by Mr. J. D. MacDonald 

 in 1938 at Kipia, 8800 feet elevation, in the Imatong >fountains. 

 The Weber specimens from the same locality, but reportedly at one 

 hundred feet lower elevation, were identified (Weber 1948) as R. 

 bursa . Weber's specimens, kindly loaned by Dr. J. Bequaert, were 

 independently identified by Dr. Theiler and by me as R. kochi . 



R. kochi is known in the Sudan only from the high mountains 

 in the central part of the eastern half of Equatoria Province. 



DISTRIBUTION 



R. kochi , a tick of the more humid and temperate highlands 

 of Central Africa, less commonly also inhabits the highlands of 

 East Africa (see also Ecology of R. compositus , p. 625). Records 

 previous to 1950 should be accepted with caution.
