Previously included the genera now assigned to the families
Tropiduridae. Frost & Etheridge (1989) proposed a division of the family Iguanidae (sensu lato) into eight separate families, later followed by another work (Frost, Etheridge, Janies & Titus 2001) in which the number of families was raised to eleven. Although these arrangements have been followed by most authors, others have retained the traditional classification (e.g., Hedges & Vidal in Hedges & Kumar 2009). See further discussion in Macey, Larson, Ananjeva & Papenfuss (1997).
