Neoanguimorpha

Neoanguimorpha is a clade of anguimorphs comprising Monstersauria (represented today by helodermatids) and Diploglossa (Xenosauridae and Anguioidea).^{[1][2][3][4][5]} Morphological studies in the past had classified helodermatids with the varanoids in the clade Platynota,^[6][7] while the Chinese crocodile lizard was classified as a xenosaurid.^[8] However molecular work found no support in these groupings and instead has found the helodermatids more related to Diploglossa, while the Chinese crocodile lizard and varanoids to form the clade Paleoanguimorpha.^[2][3]
