The Tropidurinae are a subfamily of iguanid lizards native to South America,sometimes misclassified as the Tropiduridae including the islands of Trinidad and the Galápagos. Commonly known as Neotropical ground lizards, most are ground-dwelling animals, and the subfamily includes some lizards adapted to relatively cold climates, including those of the  Andes mountains and Tierra del Fuego. Several species give birth to live young.
