This specimen, which cannot be assigned to any described sub- 

 species, is the only one of Ixodes rasus actually knovm from the 

 Sudan. 



King (1926) believed that two other ticks that had engorged 

 on him, one within the nostril the other behind the knee, while 

 he was in the Yei River area of Equatoria Province might have been 

 Ixodes rasus » 



OTHER SUDAN NOTES 



King (1926) listed Ixodes rasus from Er Renk and Kaka, Upper 

 Nile Province. The Er Renk specimen, now in Sudan Government col- 

 lections, is a female of Ixodes nairobiensis . It was taken from 

 a domestic dog on 2 July 1909, by H. H. King. Nuttall evidently 

 saw the specimen some time before he described Ixodes nairobiensis 

 (1916) because the label with this specimen reads " Ixodes rasus . 

 Nuttall 's note: Agrees with cavipalpus , but scutum longer" . The 

 Kaka. specimen is a poorly preserved nymph that appears to be I. 

 rasus but cannot definitely be assigned to this species. ~ 



DISTRIBUTION 



The actual range (and identity) of subspecies of Ixodes rasus 

 is unknown (see REMARKS below). The species is especially nximerous 

 in many parts of West and Central Africa and locally common in 

 East Africa. Material on which the few records of South African 

 specimens are based should be restvidied.
