Origin and Habitat: Stenocactus obvallatus is endemic to central México from the states of Aguascalientes, Durango, Guanajuato, Hidalgo, México Distrito Federal, México State, Oaxaca, Querétaro, San Luis Potosí, and Tamaulipas.
Habitat and Ecology: The species is very likely to occur in desert scrub. The genus Stenocactus is in need of taxonomic revision because there is a general lack of understanding on the taxonomic position of the species within the genus and thus is it no possible to define either the spatial or systematic limits of the taxon. It is not possible to establish its population size as its taxonomy is uncertain.
