Aponomma species are more mmierous in the Oriental Region 

 than in Africa but their taxonomic status is uncertain. For 

 Indo-china, Toumanoff (194A) lists three species, Anastos (1950) 

 records four from Indonesia, and Roberts (1953) studied nine 

 from Australia. None occur in Eiirope eind Neumann's (l899) lo- 

 cality label for A. laeve from Patagonia was possibly incorrect. 

 In the Americas, Tour species have been described by Schulze 

 (1932A,1936E,19/UX) but specimens available in collections 

 throughout the world are few indeed. Specific concepts in this 

 genus are much in need of careful study. 



KEY TO SUDAN SPECIES OF APONQvIMA 



1-IALES AND FEMALES 



Shiny dark brown with green or copper 



markings on scutum. (Usually on 



Varanus lizards) A. EXORNATUM 



Figures 96 to 99 



Light to dark brown with no markings 



on scutum. (Usually on snakes) A. LATUM 



Figures 1(50 to 103 



NOTE 



Ornamentation of A. exornatum is entirely lost in some pre- 

 served specimens. If "a question arises, A. exornatum males may 

 be separated from those of A. latum by the presence of welL-marked 

 festoons (inconspicuous in "S. latum ) , numerous large punctations 

 (almost none in A. latum ) , and deep, inverted, commashaped cer- 

 vical grooves (©"Esolete in A. latum ) . The last character also 

 separates females of these species.
