Approximate range of Acontias gracilicauda. The disjunct, western component is now considered a distinct species, Acontias namaquensis.

Acontias gracilicauda, the slendertail lance skink or thin-tailed legless skink, is a species of skink. [1] [2] It is found in the Republic of South Africa (Eastern Cape Province, Mpumalanga, Free State, North-West Province, Gauteng, KwaZulu-Natal) and Lesotho. [1] Acontias namaquensis was formerly included in this species as a subspecies, but is now recognized as a distinct species. [1] [2]

Acontias is a genus of limbless skinks, the lance skinks, in the African subfamily Acontinae. Most are small animals, but the largest member of the genus is Acontias plumbeus at approximately 40 cm (16 in) snout-vent length. All members of this genus are live-bearing sandswimmers, with fused eyelids. A recent review moved species that were formerly placed in the genera Typhlosaurus, Acontophiops, and Microacontias into this genus, as together these form a single branch in the tree of life. This new concept of Acontias is a sister lineage to Typhlosaurus, and these two genera are the only genera within the subfamily Acontinae.

<i>Scelotes</i> Genus of lizards

Scelotes is a genus of small African skinks.

<i>Typhlosaurus</i> Genus of lizards

Typhlosaurus is a genus of African lizards, one of a number of genera of limbless lizards in the skink family (Scincidae). This group was recently revised with most species formerly attributed to Typhlosaurus now placed in Acontias. The current definition of Typhlosaurus includes five attenuate body legless lizards from southwestern Africa. This is the sister genus to Acontias, which together form the well supported Afrotropical subfamily Acontinae.

<i>Acontias breviceps</i> Species of lizard

Acontias breviceps, the shorthead lance skink or shortheaded legless skink, is a species of viviparous, legless, fossorial lizards occurring along the southern and eastern sections of the Great Escarpment in South Africa. It may grow up to 10 cm long.

<i>Acontias percivali</i> Species of lizard

Acontias percivali, also known commonly as Percival's lance skink, Percival's legless lizard, and the Tanzanian legless lizard, is a species of small, legless (snake-like) lizard in the family Scincidae. The species is endemic to Africa.

<span class="mw-page-title-main">Woodbush legless skink</span> Species of lizard

The woodbush legless skink is a species of legless skink. It is found in the Wolkberg mountains of Limpopo Province, South Africa. Females of the species give birth to live young. This lizard species was formerly placed in a monotypic genus as Acontophiops lineatus. Morphologically the genus shows similarities to Acontias cregoi and a recent review placed both of these within the genus Acontias, which, as Acontias lineatus was already occupied, required a new name for this species.

Kasner's dwarf burrowing skink, also known commonly as Kasner's burrowing skink, is a species of lizard in the family Scincidae.

<span class="mw-page-title-main">Lygosominae</span> Subfamily of lizards

Lygosominae is the largest subfamily of skinks in the family Scincidae. The subfamily can be divided into a number of genus groups. If the rarely used taxonomic rank of infrafamily is employed, the genus groups would be designated as such, but such a move would require a formal description according to the ICZN standards.
