Previously regarded as part of the family
Cordylidae, either without recognition or mention of subfamilies (e.g., Odierna, Canapa, Andreone, Aprea, Barucca, Capriglione & Olmo 2002), or as a subfamily, Gerrhosaurinae, within
Cordylidae (e.g., Wermuth 1968; Brygoo 1985; Branch 1988; Raselimanana, Raxworthy & Nussbaum 2000). Goin, Goin & Zug (1978) referred to the subfamily as Zonurinae, although Zonurus is a synonym of Cordylus (family Cordylidae).
Other authors have regarded the two subfamilies as separate families (e.g., Loveridge 1942; Fitzsimons 1943; Lang 1991; Mouton & van Wyk 1997). However, there is now sufficient genetic evidence to regard them as separate families (Frost, Janies, Mouton & Titus 2001; Lamb, Meeker, Bauer & Branch 2003; Lamb & Bauer 2013; Bates, Tolley, Edwards, Davids, Silva & Branch 2013).
