Diploglossinae Cope, 1864

(figs. 54D, 55D, 56C)

DEFINITION: All taxa sharing a more recent common ancestor with Diploglossus fasciatus than with Anguis fragilis , Glyptosaurus sylvestris , or Gerrhonotus liocephalus .

DIAGNOSIS: The current analysis recovers two unambiguous synapomorphies for Diploglossinae as defined here: 178(0) dentary ventrally convex along its long axis and 186(1) angular process of dentary terminates anterior to the level of the coronoid process.

COMMENTS: The current analysis suggests a sister-group relationship between extant diploglossines and Apodosauriscus minutus , the latter having been originally described as close to Anniella . The current phylogenetic hypothesis should be further analyzed. Importantly, Wiens and Slingluff (2001) recovered a sister-taxon relationship between Anniella and diploglossines and Gauthier (1982) suggested that Anniella and Apodosauriscus are each other’s closest known relatives.
