EAST AFRICA ; SUDAN (Hoogstraal 1952A,195AB). 



^?KENYA: Heisch^s (195AB) specimen may represent a closely 

 related species ,_7 



NEAR EAST ; A. reflexus has been reported from Palestine 

 (Theodor 1932 ;, Turkey (Vogel 1927, Kurtpinar 195^!^) and Iran (Delpy 

 194-VB), Its occtirrence in intervening areas is to be expected, 



FAR EAST ; According to Sharif (1938), this tick, as variety 

 indicus Warbiirton, is an important pigeon parasite all over India. 



EUROPE ; In Europe, A, reflexus is generally distributed and 

 extends at least as far north as Denmark (Christiansen 193A.). It 

 occurs also in the British Isles, The Russian range of this tick 

 is said to be confined to the Caucasus, Crimea, and areas bordering 

 southern Europe (Pavlovsky 19A.8^, but Olenev (1929A,B,C ,1931A,B,C) 

 also includes Middle Asia and western Siberia, Oswald (1939) did 

 not find the pigeon tick in Yugoslavia, 



/ "AMERICAS ; Cooley and Kohls (19-^.) list western United States 

 ajid Columbia as collecting localities for ticks that they call A, 

 reflexus but that show morphological differences of yet vmknown 

 importance as species indicators, 7 



HOSTS 



Domestic pigeons are the chief host of A, reflexus and are 

 mentioned by all authors, Man is frequently attackeil, especially 

 in the vicinity of long unoccupied pigeon cotes. Chickens, horses, 

 and (in America, see above) wild birds such as the condor, swallow, 

 and screech owl (Cooley and Kohls 19^4) have been listed as hosts. 

 In the laboratory, axiy usually available mammal may serve as host. 



The literatiore contains niiraerous reports of A. reflexus biting 

 man and the painfixl sequelae of these attacks. Although the pigeon 

 argas is mostly strictly associated with pigeons, the exigencies of 

 its domestic existence drive it to attack persons, possibly more 

 frequently than does A, persicus .
