Ten Alsophis, Antillophis Pseudalsophis is a genus of snakes in the family Colubridae.

Out of the ten species, nine are endemic to the Galapagos Islands.

Species in the genus Pseudalsophis are found in Ecuador (particularly the Galápagos), Chile and Peru.

[1] Nota bene: A binomial authority in parentheses indicates that the species was originally described in a genus other than Pseudalsophis.

The specific names, slevini and steidachneri, are in honor of American herpetologist Joseph Richard Slevin and Austrian herpetologist Franz Steindachner, respectively.
