Van Dam's girdled lizard (Smaug vandami) is a species of lizard in the family Cordylidae. The species is endemic to South Africa.
The type locality of S. vandami is Gravelotte, Limpopo, South Africa. [3]
The preferred natural habitats of S. vandami are grassland and savanna. [1]
A large lizard, S. vandami may attain a snout-vent length (SVL) of 14.5 cm (5.7 in). [4] It has a triangular shaped head, and spiny dorsal scales. The predominant colour is dark brown with fragmented yellow rings. [5]
S. vandami is largely solitary and hides in cracks in rocks. [6]
S. vandami is ovoviviparous. [2] From two to six young are born alive in summer. [6]
The species is named for the collector of the type specimens, Gerhardus Petrus Frederick van Dam (died 1927), who was a South African herpetologist. [2] [7] [8]
Other common names for S. vandami include the Afrikaans name ouvolk, meaning "old folk". [9]
The genus Cordylus 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. Most species are rupicolous (rock-dwelling), 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.
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.
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.
Lawrence's girdled lizard is a species of lizard in the family Cordylidae. The species is endemic to South Africa.
Mitchell's flat lizard is a species of lizards in the family Cordylidae.
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.
The Mozambique girdled lizard or flame-bellied armadillo lizard is a large, flattened, girdled lizard found on Mount Gorongosa in Mozambique and low elevations in the Chimanimani Mountains at the border of Zimbabwe and Mozambique. It lives in rock outcrops in grasslands and dry, wooded mountain slopes.
The Transvaal girdled lizard or Reichenow's spiny-tailed lizard is a very flattened girdled lizard from northeastern South Africa, Swaziland, and southeastern Botswana. It prefers rock outcrops in open grassland and feeds on small arthropods, especially beetles.
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.
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.
Warren's girdled lizard is a species of relatively large, flattened lizard in the family Cordylidae. The species is native to Southern Africa.
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
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.
Karusasaurus, commonly known as Karusa lizards, is a genus of lizards in the family Cordylidae.
Namazonurus, is a genus of lizards, commonly known as Namaqua girdled lizards, in the family Cordylidae. The genus contains five species, which are endemic to southern Africa, and feed on insects and small vertebrates.
Van Dam's dwarf worm lizard, also known commonly as the sand-dwelling dwarf worm lizard and Van Dam's round-headed worm lizard, is a species of amphisbaenian in the family Amphisbaenidae. The species is native to southern Africa. There are two recognized subspecies.
Smaug breyeri, also known commonly as the Waterberg dragon lizard or the Waterberg girdled lizard, is a species of lizard in the family Cordylidae. The species is endemic to South Africa.
