Distribution and habitatEdit

Found in North America from southwestern Canada south through the western United States into northwestern Mexico.[1]


Species[2] Taxon author[2] Subsp.*[2] Common name[2] Geographic range
C. bottaeT (Blainville, 1835) 0 Rubber boa Southwestern Canada in southeastern British Columbia. The northwestern and western United States in most of Washington, Oregon, Idaho, western Montana and Wyoming, northern and central Utah, and as far south as northern Nevada and Monterey County, California.[1][3]
C. umbratica Klauber, 1943 0 Southern rubber boa The United States in southern California (Riverside and San Bernardino counties).[3]

*) Not including the nominate subspecies.
T) Type species.[1]


Sources vary on how many species the genus contains. Some consider the rubber boa, C. bottae, to be the sole member of the genus. In addition, some experts consider the southern rubber boa, C. umbratica to be a subspecies of C. bottae. Although the Calabar python, Calabaria reinhardtii has been included in Charina, recent phylogenetic analyses based on DNA have shown that it does not belong to this genus.[4]
