Diploglossa

Diploglossa is a clade of neoanguimorphs represented by the families Xenosauridae, Diploglossidae, Anniellidae and Anguidae, the latter three placed in the superfamily Anguioidea.^[1][2][3][4] In the past the Chinese crocodile lizard was classified as a xenosaurid;^[5] current molecular work has shown evidence the species related to varanoids in the clade Paleoanguimorpha.^[1][2][6]
