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]
