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
T. validus is found in the Mexican states of Baja California Sur, Chihuahua, Guerrero, Jalisco, and Sonora.[2]
Reproduction
T. validus is viviparous.[2]
Subspecies
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
The subspecific name isabelleae is in honor of the American wildlife artist Isabelle Hunt Conant, the wife of the American herpetologist Roger Conant.[3]
