The Lacertoidea is a group of lizards that includes the Lacertidae, Teiidae, Gymnophthalmidae, and, according to recent molecular analyses, the burrowing Amphisbaenia. Studies of anatomy have traditionally grouped the lacertoids with skinks, however more recent studies focusing on DNA have placed them as a distinct group of lizards. The relationships of the Amphisbaenia to other lizards have long been a mystery. Although superficially snakelike, their anatomy and locomotion is quite distinct from that of snakes. However, they do not closely resemble any other group of lizards. Recent molecular studies suggest that amphisbaenians are grouped with the Lacertidae, in a group named the Lacertibaenia.
