1950j as H. plimibeTim turanicum ) and a single specimen has been coL- 

 lected in''Afghanistan (Anastos 195^j as H. rufipes glabrum ) . 



H. marginatum tiiranicum Pomerantzev, 1946 /subsequently (1950) 

 considered as a subspecies of H. plumbeum by the same author 7 is 

 obviously the same tick as H. rufipes glabrum Delpj'', 1949. Tt is 

 necessary, therefore, to give the Soviet name priority. There is 

 no biological reason or taxonomic utility for considering H. 

 turanicim as a subspecies of any species. Theiler (1956) "continues 

 to apply the name H. glabrum to South African populations of this 

 species. " 



Rousselot (1951) reported H. rufipes glabrum from French West 

 Africa but omitted it from his T953B work, apparently after having 

 reconsidered the identification of pertinent material. Villiers 

 (1955) also used this name for material from the same area. It 

 is assumed that these data refer actually to H. rufipes . 



Fonesca, Pinto, Colaco, Oliveira, Branco, da Gama, Scares 

 Franco, and Lacerda (1951) reported "H. rufipes glabrata " from 

 Portugal, but Theiler, who has seen their material, states (cor- 

 respondence) that it is an entirely different species, probably 

 H. marginatum . 



According to Pomerantzev (1950) the biology of H. turanicum 

 was reported in 1945 by Lototsky, pp. 69-130, but it~has been 

 impossible to secure further details for the present study. The 

 distribution of this tick is stated to be southern Khazakstan, 

 Middle Asia, and Iran. To this range, the South African Karroo 

 and Afghainistan should be added. 



Where it occurs in the Soviet area, H. turanicum ranges 

 through a number of altitudinal zones. I^ lives in tugai meadows, 

 in semidesert, and in low areas of fields at the base of hills 

 and on mountain slopes to the wooded belts. Adult hosts are 

 "large and small horn- bearing animals", especially cattle, and 

 also horses. A single Afghanistan male was taken from a camel 

 (Anastos 1954). Immatiire stages attack birdsj these hosts are 

 listed below and those most commonly infested are preceded by 

 an asterisk.
