Certain unusual morphological characters of this easily recog- 

 nized species cause the tortoise hyalomiaa to be considered in a 

 separate subgenus, Hyalorainasta Schulze, 1930. 



H. aegT.'-ptium punctata Schulze, 1919 (see also Kratz 19A-0) , a 

 name proposed for a single specimen from Malta and subsequently 

 overlooked by even Schulze himself, is undoubtedly a synonym of 

 H. aegyptium. 



Pomerantzev (1950) considers Dermacentor rosmari Ass (1935 )» 

 described from nymphs from walrus in the Kara (White J Sea and 

 said to be the northernmost ticks on record, as a sj-nonym of H. 

 aegyptium . On the basis of the original description and illus- 

 trations of D. rosmari , its systematic position is uncertain but 

 this synonyny is hardly convincing. 



The sj-nonjinous name H. syriacum Koch, 18^^-, has frequently 

 been used for the actual H. aegyptium . So far as has been deter- 

 mined, H. s^yTiacum has been confused with no other species. 



Both sexes can be readily distinguished from key characters 

 provided herein.
