Calyptocephalella is a genus of frogs in the family Calyptocephalellidae. It is represented by a single living species, Calyptocephalella gayi, commonly known as the helmeted water toad, Chilean helmeted bull frog or wide-mouth toad. Additionally, there are a few extinct species that only are known from Late Cretaceous and Paleogene fossil remains from Patagonia in South America and in the Antarctic Peninsula (at times when it was warmer and wetter). The helmeted water toad living today is aquatic to semi-aquatic, and found in deep ponds and reservoirs in central Chile and possibly adjacent west-central Argentina.AmphibiaWeb: Calyptocephalella gayi.
