Hemiphractidae
The Hemiphractidae are a family of frogs from South and Central America. Previously, this group had been classified as a subfamily (Hemiphractinae) under family Hylidae. More recent research classifies these genera into their own family, or sometimes into three separate families: Amphignathodontidae ( Flectonotus and Gastrotheca), Cryptobatrachidae ( Cryptobatrachus and Stefania), and Hemiphractidae ( Hemiphractus). An active question still exists as to which of these groupings is more accurate.
