As generally used, Pelobatidae (for megophryines and pelobatines) is not demonstrably monophyletic, because of the ambiguous relationships of Pelodytes.
The name Pelobatidae was defined by Ford and Cannatella (1993) as the node that is the most recent common ancestor of living Pelobates, Scaphiopus, and Spea, and all of its descendants.
Synapomorphies of Pelobatidae include fusion of the joint between the sacrum and coccyx, exostosed frontoparietals, and the presence of a metatarsal spade supported by a well-ossified prehallux.
