So far unknown Thamnophis representatives are discovered again and again. The species classification of these widespread animals is also being redesigned with the help of modern genetic analyzes . As recently as 2003, seven new subspecies of the Mexican garter snake were described. The former subspecies Thamnophis eques cyrtopsis was assigned its own species status.
distribution
The natural habitat of the Mexican garter snakes stretches from southern Arizona and New Mexico in the USA to Mexico (there near the Pico de Orizaba northwest over Sonora and Chihuahua ). Isolated populations have also been found in the Mexican states of Oaxaca and Nuevo León .
In the US, the Mexican garter snakes are endangered, especially since the spread of the bullfrog , the competitor for food and also predator (predator) is the garter snakes.
