workers for this group. When their 

 revision of the D. auratus group is 

 published, NuttaTl's collections of 

 these taxa will need to be restudied. 



In Africa, the Rhipicephalus sanguineus 

 group currently contains R. bergeom , 

 R_. camacasi , R_. guilhoni , R. moucheti , 

 R. sanguineus , R. serranoi , R. sulcatus 

 Ttwo ecologicalTy and morphoTogically 

 distinct entities), and R_. turanicus . 

 The first three species are not well 

 known, and the first two may be present 

 in R. sanguineus collections, especially 

 in the horn of Africa. R. guilhoni is 

 characteristically a North and West 

 African livestock tick and may be widely 

 distributed. R^. moucheti is a rare 

 species, known only from a few specimens 

 from Guinea, Benin, and Cameroon. 

 Biosystematic investigations on the 

 R. sanguineus group are being conducted 

 Fy R. G. Pegram and coworkers. Specific 

 identification of this group awaits the 

 results of these studies.
