 (= H. BRUNNKLFARMATUM S. and S., 1930).

 THE PARMATED AraiCAN HYALCMMA 



H. albiparmattim , presently known only from Kenya, Tanganyika, 

 and Togo, is similar to H. tiauacatum except that the central fes- 

 toon is differentiated as a parmaTn the form of a cellailoidlike 

 cover of variable size, shape, and color. No constant characters 

 have been discovered for differentiating females of these two 

 species. 



Delpy (1949B) considered H. impressum albiparmattim Schulze 

 and Schlottke, 1930, from East Africa, as a synonym of H. raar- 

 ginatijm (= H. savignyi ) or questionably of H. truncatum (= H. 

 transiens jj^he considered H. brimneiparmatum of Schulze and 

 Schlottke (1930) to be a synonym of H. marginatvun (= H. savignyi ). 



Feldman-Mvihsam (1954-) stated, after examining Kenya laboratory- 

 reared material of H. albiparmatum submitted by J. B. Walker that 

 H. albiparmatum is a synonym of H. truncatum . Dr. Theiler and the 

 writer, after examination of the^same material, are convinced that 

 Walker's H. albiparmatum is a distinct genetic entity worthy of 

 full species rank. It is also apparent from Walker's material 

 and from other series in British Museum (Natiiral History) collec- 

 tions that H. impressum brunneiparmatum Schulze and Schlottke, 

 1930, from Togo is a synonym of H. albiparmatum and not of H. 

 truncatum as stated by Feldman-Muhsam 1954 • F^ss Walker is 

 preparing a report on this species for publication in Parasitology. 

 Hosts of the parmated African hyalomma appear to be the same as 

 those of H. truncatum. 



British Museum (Natural History) collections contain material 

 from cattle and from a rhinoceros from Zatta Plains, Kajiado, 

 Najnanga, and the Masai Reserve, Kenya (HH det.). J. B. Walker 

 (conrespondence) has seen specimens from a rhinoceros from Iringa 

 District, Tanganyika, and from a warthog in Ghunya District, 

 Tanganyika.
