HYALCMMA SPECIES NO. 1 NEAR EXCAVATDM 

 (Figures 331 to 334) 



DISTRIBUTION 



This species occurs in EGYPT and probably extends eastward 

 and westward from here. 



HOSTS 



Adults feed on camels; immature stages on lizards, Acantho -. 

 dactylus and Agama . In the laboratory, rabbits serve as host 

 for all stages and man has been utilized to feed adults. 



BIOLOGY 



This is a fairly common tick locally on Egyptian desert 

 lizards. Life cycle and other biological data will be pre- 

 sented subsequently (Hoogstraal, ms.). 



RMARKS 



Although probably already described, we are not yet certain 

 which name applies to this species. The male runs to H. excava - 



tm in the Delpy (1949A) and in the present (page 397)''keysT 



The female superficially resembles that of H. detritum but is 

 morphologically distinct from all others. Tn size, both sexes 

 are considerably larger than H. excavatum . Adults, reared from 

 nymphs removed from Egyptian lizards, have produced uniform F]_ 

 adults, thus indicating the validity of this species. All spec- 

 imens are remarkably similar, a phenomenon seldom seen in this 

 genus. However, further search of field collections and addi- 

 tional rearing will probably reveal more variable individuals.
