Gerrhonotus parvus (common name: pygmy alligator lizard) is a species of lizard in the subfamily Gerrhonotinae. It is endemic to the state of Nuevo León, Mexico.[2][3] The name parvus is from the Latin word for small because it is the species of smallest adult size recognized in the genus Gerrhonotus.[4] It lives in dry forests transitioning to scrub in the eastern Sierra Madre Oriental at elevations of 900–1,650 m (2,950–5,410 ft) above sea level. They are usually found among dead leaves of yuccas in open wood areas.[4] It seems to prefer dry limestone canyons.[3] It is a relatively small species, with the maximum reported snout–vent length at 76 mm (3.0 in).[2] It is oviparous and has a litter size of 4–6 eggs.[3] Its head is glossy and smooth, grayish brown in color with scattered dark spots.[4] The lips are peppered with pigment and the chin and throat are white in color.[4]
