Leiopelmatidae

Archaeobatrachia is a suborder of Anura containing various primitive frogs and toads. As the name literally suggests, these are the most primitive frogs. Many of the species (28 in total) show certain physiological characteristics which are not present in other frogs and toads, thus giving rise to this group. They are largely found in Eurasia, New Zealand, the Philippines and Borneo, and are characteristically small. In addition, the family Ascaphidae is found in the Pacific Northwest of the United States, and is only represented by two species.
