Cordylus


The genus Cordylus includes a wide variety of small- to medium-sized spiny lizards from Africa, collectively called girdle-tailed or girdled lizards. All are diurnal and ovoviviparous. Most species are rupicolous, while a few species are arboreal or live in burrows. They defend themselves with osteoderms and by quickly retreating into rock crevices or burrows. Many species live in groups and males defend territories.
Cordylids are generally listed under CITES Appendix II. They are not necessarily threatened with extinction, but trade is controlled to prevent overexploitation. Some species of Cordylus have limited ranges and may be threatened with habitat destruction or over collecting for the pet trade.

Classification

Broadley recognized 47 species in the genus Cordylus, including eight species originally placed in the genus Pseudocordylus and Hemicordylus capensis. The greatest diversity of cordylids is in South Africa, with a few species found in Angola and eastern Africa as far north as Ethiopia. Other members of the Cordylidae are the genera Chamaesaura and Platysaurus. The sister group of Cordylidae is the plated lizards, family Gerrhosauridae.
In 2011, a study based on the molecular phylogeny of the family suggested several species traditionally included in Cordylus should be moved to other genera: Hemicordylus, Karusasaurus, Namazonurus, Ninurta, Ouroborus and Smaug. This classification is supported by the Reptile Database where 22 species remain in Cordylus.
