Equatorial Africa (CNHM). Reptiles reported to be attacked are 

 crocodile (Schwetz 1927B, Villiers 1955), cobra (Loveridge 1923C), 

 tortoise (Loveridge 1936B), python (Howard 1908), tortoise and 

 snakes (Mettam 1932), snake (Theiler 1945A), and blind lizard, 

 Acontias plumbeus (Bedford 1936). A bird, the black- chested har- 

 rier eagle, is also known as a host (Theiler, unpublished). 



BIOLOGY 



Aside from remarks in the generic introduction and host re- 

 view, nothing additional has been reported for this species. 



DISEASE RELATIONS 



It is of interest to conjecture that these ticks may transmit 

 the hemogregarines so frequently found in reptiles. 



It is claimed that natural infections of Q fever (Coxiella 

 burnetii) have been found in this species. 



REMARKS 



A conplete siiramary of the taxonomy, morphology, and distri- 

 bution of this species has been presented by Theiler (1945A). 

 Mai formed specimens have been described by Santos Dias (1948A), 

 Schulze (1950B), and Tendeiro (1951B). Schulze (l9/k3B) discussed 

 certain aspects of the nymphsil gut of this species, and (l9Al) 

 features of the haller's organ, and (1950B) of the dorsal foveae 

 and festoons. 



Should male specimens with only narrow lateral ornamentation 

 be found, the presence of A. ochraceum Neumann, 1901, or of A. 

 fraud igerum Schulze, 1935,'~should be considered (cf. Theiler"'l945A 

 and Santos Dias 1955C for descriptions and illustrations). 



Tendeiro (194-8) mentioned A. halli sp. nov., without descripu 

 tion (i.e. a no men nudum) and (1950J described as A. hnll i sp. nov. 

 specimens from Portucese Giiinea that conform to alT specimens 

 stxadied from the SiJdan. The first coxal spur is single; there is
