Physalaemus

Physalaemus is a large genus of leptodactylid frogs. These frogs, sometimes known as dwarf frogs or foam frogs, are found in South America. It is very similar to Leptodactylus, a close relative, and indeed the recently described Leptodactylus lauramiriamae is in some aspects intermediate between them. They have been described by researchers as presenting one of the most puzzling taxonomic histories among Neotropical anurans because of the occurrence of highly polymorphic and cryptic species.

Physalaemus is a large genus of leptodactylid frogs. These frogs, sometimes known as dwarf frogs or foam frogs, are found in South America.1 It is very similar to Leptodactylus, a close relative, and indeed the recently described Leptodactylus lauramiriamae is in some aspects intermediate between them.2 They have been described by researchers as presenting one of the most puzzling taxonomic histories among Neotropical anurans because of the occurrence of highly polymorphic and cryptic species.3

Species

There are 5113 or 50 species (AmphibiaWeb lists Physalaemus nattereri as Eupemphix nattereri ):4
