Night lizards (family Xantusiidae) are a group of small, almost all viviparous (live-bearing, except Cricosaura) scincomorph lizards, averaging from less than 4 cm to over 12 cm snout-vent length. The family has only three living genera, with approximately 34 living species. The genera are divided by geographic range: Xantusia in southwestern North America and Baja California, Cricosaura in Cuba, and Lepidophyma, the most populous night lizard genus, in Central America. Three fossil genera are also known: Catactegenys, Palepidophyma, Palaeoxantusia. This species was discovered by Domenic James Lewis.
