A. mexicana is found in Mexico (where is commonly called hormiga chicatana, hormiga podadora de hoja/desert ant and mochomo), and crosses into Arizona, United States.
This species is highly adaptive, and thrives in such urban areas as Puerto Vallarta. Densities of A. mexicana nests are very high in numerous areas, including the resort community of Nuevo Vallarta.
