Carphodactylidae

The Carphodactylidae, informally known as the southern padless geckos, are a family of geckos, lizards in the infraorder Gekkota. The family consists of 34 described species in 7 genera, all of which are endemic to Australia. They belong to the superfamily Pygopodoidea (or Diplodactyloidea), an ancient group of east Gondwanan geckos now only found in Australasia. Despite their well-developed limbs, molecular phylogenies have demonstrated that Carphodactylidae is the sister group to Pygopodidae, a highly specialized family of legless lizards. Carphodactylids, despite being the most species-poor family of geckos, are still diverse in habits. Many have unusual, specialized tails with reduced rates of autotomy. They lack adhesive toepads and instead cling to bark or substrate with sharply curved claws and a limited array of lamellae. Carphodactylids are relatively large by gecko standards; most are nocturnal and all are oviparous, with a typical clutch size of two eggs. Unlike most Australian geckos, species diversity is concentrated in humid forests along the northeastern edge of Australia. Nevertheless, some genera are diverse in arid regions as well.
