Genera

Many, see text

The Natricinae are a subfamily of the Colubridae family of snakes, which comprises 28 genera. Members include many very common snake species, such as the European grass snakes, and the North American water snakes and garter snakes. Some members of the subfamily are known as keelbacks, because their dorsal scales exhibit strong keeling.

Classification

While often regarded as a subfamily of the Colubridae,[1] in some classifications, they are raised to the family level as Natricidae.[2][3]

They are recognised as a sister group of the Dipsadinae plus the Pseudoxenodontinae.[1]

Genera

In addition, the following genera are often placed here, but may belong elsewhere:
