Arizona, and only sixteen species range westward into California, the vast 
Mojave Desert acting as a formidable ecological barrier. 
Although the above list is by no means thought to be conclusive, it 
appears that the Cerambycid fauna of the Hualapai Mountains is comprised 
primarily of southern Arizona Sonoran and Montane forms with the faunal 
elements of California and the Rocky Mountains exerting a minor influence. 
It also appears that the Hualapai Mountains represent the northern and 
western distributional limits of many of the species.
