To clarify: There is was an ecology paper published in the early '90s that defined a large ecoregion including California, Nevada, Utah, New Mexico, Arizona along with México as Megaméxico.
“It is important to remember that the geographic distribution of organisms generally ignores the political divisions of the planet’s crust and is instead frequently linked to the delimitation of natural regions defined by physiographic, climatic, edaphic, etc. conditions. The term “Megaméxico” will be used when including parts of the Sonoran, Chihuahuan, and Tamaulipan arid zones that belong to the United States of America.”
