Enyalius is a genus of lizards in the family Leiosauridae. The genus is endemic to Brazil and Uruguay. The Enyalius genus is mostly insectivorous (meaning they eat insects and other invertebrates), diurnal (active during the day), and inhabits trees. There are currently ten known species of this genus: E. brasiliensis, E. boulengeri, E. iheringii, E. perditus, E. pictus, E. erythroceneus, E. leechii, E. catenatus, E. bibronii, and E. bilineatus. The reproductive timing for the E. perditus species occurs typically in warm and wet seasons and is typically shorter than other species of this genus. These lizards lay eggs and have clutch size (number of eggs laid at one time) of about 3-11.
