The bolsón night lizard (Xantusia bolsonae) is a species of night lizard in the family Xantusiidae. The species, which was originally described by Robert G. Webb in 1970, is endemic to the state of Durango in Mexico. Not much is known about the lizard at present, as it appears to be simultaneously rare and rather secretive in nature.
