Contents:
  34 species of which 27 (79.4%) are endemic - 6 genera of which 2 (33.3%) are endemic (as of December 31st, 2018).

Remarks: The genera contained in this family were previously included in the family Iguanidae (e.g., Peters & Donoso-Barros 1970). Separate family status was given by Frost & Etheridge (1989) as Polychridae, in which family they also included the genera later assigned to Dactyloidae and Leiosauridae. Subsequently, the family name was corrected by Frost, Etheridge, Janies & Titus (2001) to Polychrotidae, and they named a new family, Leiosauridae, for the genera now assigned to this family.

Distribution:  South America.
