Range Description

This species is known only from the southwest of the United States. Its known range includes only Arizona, from the Grand Canyon and the Coconino Plateau eastward onto the Navaho Reservation; an apparently disjunct population occurs in the Mazatzal Mountains, Gila County, Arizona (Wright and Lowe 1993). Persons and Wright (1999) documented the occurrence of a population of the A. inornata group, most closely resembling A. pai, in Petrified Forest National Park (Navajo and Apache counties, northeastern Arizona).
