Description
Adults usually grow to 60-70 cm, although exceptionally large specimens may be as much as 100 cm in length.[2]
Geographic range
Found on the plateau of central Mexico from southern Zacatecas and northeastern Colima east to east-central Veracruz. Occurs at elevations between 1,450 m and 2,600 m. The type locality given is "Table Land, Mexico", although a restriction to "Tupátaro, Guanajuanto, Mexico" was proposed by Smith and Taylor (1950).[1]
Conservation status
This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001).[5] Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend is down. Year assessed: 2007.[6]
