The genus Cordylus (Sauria: Cordylidae) includes a wide variety of species of small to medium spiny lizards from Africa, collectively called girdle-tailed lizards or girdled lizards. All are diurnal and ovoviviparous (live-bearing, without shelled eggs). Most species are rupicolous (rock-dwelling), while a few species are arboreal or live in burrows. They defend themselves with osteoderms (flat bony plates in the skin) 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 (2006) recognized 47 species in the genus Cordylus, including eight species originally placed in the genus Pseudocordylus (P. fasciatus, P. langi, P. melanotus, P. microlepidotus, P. nebulosus, P. spinosus, P. subviridis, and P. transvaalensis) 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 (a group of legless lizards from southern and eastern Africa) 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 (for capensis and nebulosus), Karusasaurus (for jordani and polyzonus), Namazonurus (for campbelli, lawrenci, namaquensis, peersi and pustulatus), Ninurta (for coeruleopunctatus), Ouroborus (for cataphractus) and Smaug (for breyeri, giganteus, mossambicus, regius, vandami and warreni). [1] This classification is supported by the Reptile Database where 21 species remain in Cordylus. [2]

<i>Pseudocordylus</i> Genus of lizards

Pseudocordylus is a genus of small to large girdled lizards from South Africa, commonly known as crag lizards. Six species of Pseudocordylus are known; they are distinguished from girdled lizards of the genus Cordylus by the presence of granular scales on the back instead of osteoderms.

<span class="mw-page-title-main">Armadillo girdled lizard</span> Species of reptile in the family Cordylidae

The armadillo girdled lizard, also commonly known as the armadillo lizard, the armadillo spiny-tailed lizard, and the golden-armadillo lizard, is a species of lizard in the family Cordylidae. The species is endemic to desert areas along the western coast of South Africa. In 2011, it was moved to its own genus based on molecular phylogeny, but formerly it was included in the genus Cordylus.

<span class="mw-page-title-main">Giant girdled lizard</span> Species of lizard

The sungazer, also known as the giant girdled lizard, giant dragon lizard, ouvolk, or giant zonure, is the largest species of the Cordylidae, a family of lizards from sub-Saharan Africa. This threatened species is endemic to Highveld grasslands in the interior of South Africa. In 2011, it was assigned to the new genus Smaug, along with seven other species previously belonging to the genus Cordylus, based on a comprehensive molecular phylogeny of the Cordylidae.

<span class="mw-page-title-main">Limpopo girdled lizard</span> Species of lizard

The Limpopo girdled lizard, also known commonly as Jones's armadillo lizard and Jones's girdled lizard, is a species of lizard in the family Cordylidae. The species is endemic to Southern Africa.

<span class="mw-page-title-main">East African spiny-tailed lizard</span> Species of lizard

The East African armadillo lizard, dwarf sungazer, or tropical girdled lizard is a species of arboreal or rupicolous (rock-dwelling) lizard endemic to East Africa.

An isolated population of the Rhodesian girdled lizard from granite outcrops in montane grassland of northern Malawi was recently redescribed as Cordylus nyikae. Unlike the Rhodesian girdled lizard, the head shields of this species are very rugose, the nostrils are pierced in the lower posterior corner of the nasal scales, and the dorsals do not have a serrated posterior margin. The dorsal coloration is dark brown to gray-brown with lighter spots. The tail and upper lips are light brown. The belly is buff. Its common name is Nyika girdled lizard.

Cordylus meculae, the Mecula girdled lizard, is a third species from the Rhodesian girdled lizard complex, and was described from Mount Mecula in northern Mozambique. It lives in granite outcrops of montane grasslands and dry miombo woodland. The nostril pierces the center of the nasal scale and the head shields are rugose. The dorsal coloration is dark brown with paler infusions on the flanks. The head is almost black with yellow lips and scattered yellow flecks on the head and neck. The belly is buff colored.

The Rhodesian girdled lizard is one of three species of very flattened girdled lizards from Zimbabwe, Malawi, and Mozambique. The other two species are Cordylus nyikae and Cordylus meculae. They are found living under stones in rock outcrops where they feed on small arthropods. Adults are 60–90 mm long from snout to vent. The tail length is approximately half the total length.

<i>Ninurta coeruleopunctatus</i> Species of lizard from South Africa

Ninurta coeruleopunctatus, the blue-spotted girdled lizard or simply blue-spotted lizard, is a monotypic genus that is endemic to southern, coastal South Africa. The Ninurtacoeruleopunctatus, as a member of the Cordylinae subfamily, demonstrates significant variability in body armor. This variation is a cause of the diverse evolutionary pressures within the subfamily. The environments aridity is the significant cause for this body armour's evolution.

Hemicordylus, the false girdled lizards, is a genus comprising two lizard species endemic to the Cape Fold Belt of southern South Africa.

Namazonurus campbelli, commonly known as Campbell's girdled lizard, is a species of lizard in the family Cordylidae. A small girdled lizard, N. campbelli is endemic to Namibia. It is often mistaken for the more common Herero girdled lizard, N. pustulatus, as they both are similar in size and have flattened bodies. N. campbelli lives in rock crevices and cracks on dry mountain slopes

<i>Smaug</i> (lizard) Genus of lizards

Smaug is a genus of lizards in the family Cordylidae. The genus Smaug is a group of species of spiny southern African lizards, separated from the genus Cordylus in 2011 on the basis of a comprehensive molecular phylogeny of the Cordylidae. The type species is the giant girdled lizard, S. giganteus.
