Range Recorded by Stefan Cover in numerous collections at 1200-1900 m in the following mountain ranges of southeastern Arizona: Chiricahua, Dragoon, Huachuca, Pajarito, Pinal, and Sierra Ancha.
Biology Stefan Cover (unpublished collection notes) found vallicolaHNS to favor creek banks and open woodland with a wide range of species composition, from ponderosa pine to oak, pine-oak-juniper, and oak-mesquite-sumac. Nests were usually under stones in either shade or exposed areas, although occasionally they had been constructed in open soil.
