The West Coast garter snake (Thamnophis validus), also known commonly as Kennicott's water snake, is a species of snake in the subfamily Natricinae of the family Colubridae. The species is endemic to Mexico. Four subspecies are recognized.
Geographic range
[edit]T. validus is found in the Mexican states of Baja California Sur, Chihuahua, Guerrero, Jalisco, and Sonora.[2]
Reproduction
[edit]T. validus is viviparous.[2]
Subspecies
[edit]There are four subspecies of T. validus which are recognized as being valid, including the nominate subspecies.[2]
- T. v. celaeno (Cope, 1861) – cape garter snake, Mexican Pacific lowlands garter snake
- T. v. isabelleae (Conant, 1953)
- T. v. thamnophisoides (Conant, 1961)
- T. v. validus (Kennicott, 1860)
Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Thamnophis.
Etymology
[edit]The subspecific name isabelleae is in honor of the American wildlife artist Isabelle Hunt Conant, the wife of the American herpetologist Roger Conant.[3]
