Lacertoidea

Red worm lizard Amphisbaena alba, photographed by Diogo B. Provete.


Belongs within: Lepidosauria.
Contains: Lacertidae, Gymnophthalmidae, Teiidae.

The Lacertoidea are a group of lizards including the Old World Lacertidae and the New World Teioidea. It has recently been indicated that the Amphisbaenia, burrowing lizards with reduced or absent limbs, are also members of this clade (Müller et al. 2011). Members of the genus Bipes of southern North America retain small forelimbs whereas other amphisbaenians are limbless.

Potential lacertoids also include the Polyglyphanodontia, an Upper Cretaceous group of lizards characterised by tricuspid teeth, subapical tooth implantation, a V-shaped dentary symphysis, and a long splenial that slots into the subdental shelf (Longrich et al. 2012).
