Conservation: IUCN – Data Deficient as M. m. codiensis and M. m. zygomaticus, Vulnerable as M. m. fucosus and M. m. nevadensis , Lower Risk (nt) as M. m. arizonensis and M. m. rivularis , otherwise Lower Risk (lc).

Discussion: Subgenus Mynomes , montanus species group ( Zagorodnyuk, 1990). Geographic variation and subspecific classification assessed by Anderson (1959), who viewed M. oeconomus as its sister species. Hooper and Hart (1962) arranged M. montanus with M. pennsylvanicus and M. townsendii , a general relationship corroborated by karyotypic and genic analyses ( Modi, 1987; Moore and Janecek, 1990). Two karyotypic morphs reported by Judd et al. (1980), who raised the question of their specific distinction. See Sera and Early (2003, Mammalian Species, 716).
