Autarchoglossa is
clade (evolutionary grouping) of
squamates that includes
skinks,
anguimorphs,
snakes, and relatives. Autarchoglossa is supported as a
monophyletic grouping (i.e. a valid clade) by morphological features in living and extinct lizards and snakes. Some
phylogenetic analyses based on molecular features such as DNA sequences in living squamates do not support Autarchoglossa.
