Banks believes that Amblyomma, Hyalomma and Aponomma are more 

 nearly related to each other than to Dennacentor, and that Dermacentor is 

 more closely related to Amblyomma than to Rhipicephalus. 



Warburton also places ticks in the superfamily Ixodoidea, which he 

 divides into the families Argasidae and Ixodidae ; the latter he groups as 

 follows :
