These are the only definite records of R. sulcatus from 

 the Sudan. Those reported by King (1926) have proven, upon 

 examination of his specimens by Dr. Theiler, to be R. _s. san- 

 guineus . A single male was R. supertritus . 



DISTRIBUTION 



(Known Correct References ) 



As now known, the range of R. sulcatus extends from the 

 Congo and southwestern Sudan to Uyasaland. Whether this dis- 

 tributional picture is more restricted than this tick's range 

 in natiire remains to be seen. 



CENTRAL AFRICA ; "CONGO" /"Type locality as stated by Neumann 

 (190^71 According to Bequaert (1931 ) this probably refers to 

 French Equatorial Africa (French Congo) but Theiler and Robinson 

 (1953B) refer it to the Belgian ZongoJJ 



EAST AFRICA ; SUDAN /"Hoogstraal (195'i^B) . Material iden-
