Though occurring in both cave and epigean habitats, N. atoyaca is primarily a surface centipede. It is the second most widely distributed species of Newportia in Mexico after N. oreina, spanning some 530 mi (848 km), north­south, and around 168 mi (268.8 km), east­west. The ranges of the two species are similar, and they are the dominant representatives in central Mexico. They differ solely in the number of pseudotarsi on the ultimate legs, N. oreina having 5–8 and N. atoyaca having 11–12, and may be synonyms.
