Physalaemus nattereri is a frog native to central and southeastern Brazil and eastern Bolivia and Paraguay.
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.
Itapotihyla is a genus of frogs in the family Hylidae. It is monotypic, being represented by the single species Itapotihyla langsdorffii, commonly known as the ocellated treefrog. It is found in the Atlantic Forest biome of Brazil, with an isolated population in eastern Paraguay and adjacent Brazil and northeastern Argentina.
Physalaemus aguirrei is a species of frog in the family Leptodactylidae. It is endemic to eastern Brazil and occurs in the southern Bahia, northern Espírito Santo and northeastern Minas Gerais. The specific name aguirrei honours Alvaro Coutinho Aguirre, a Brazilian zoologist. However, common name Linhares dwarf frog has been proposed for it.
Physalaemus albonotatus is a species of frog in the family Leptodactylidae. It is found in Brazil, Paraguay, and Chacoan Argentina and Bolivia.
Physalaemus barrioi is a species of frog in the family Leptodactylidae. It is endemic to Serra do Bocaina in São Paulo state, Brazil. The specific name barrioi honors Avelino Barrio, a Spanish botanist and zoologist who lived in Argentina. However, the common name Bocaina dwarf frog has been proposed for it.
Physalaemus biligonigerus is a species of frog in the family Leptodactylidae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Its natural habitats are subtropical or tropical dry forests, temperate shrubland, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, temperate grassland, subtropical or tropical dry lowland grassland, subtropical or tropical seasonally wet or flooded lowland grassland, freshwater lakes, intermittent freshwater lakes, freshwater marshes, sandy shores, arable land, pastureland, plantations, rural gardens, urban areas, heavily degraded former forest, water storage areas, ponds, irrigated land, seasonally flooded agricultural land, and canals and ditches.
Physalaemus crombiei is a species of frog in the family Leptodactylidae. It is endemic to Brazil. Its natural habitats are subtropical or tropical moist lowland forests and intermittent freshwater marshes. It is threatened by habitat loss.
Physalaemus cuqui is a species of frog in the family Leptodactylidae. It is found in Argentina, Bolivia, and possibly Paraguay. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, intermittent freshwater marshes, arable land, pastureland, ponds, irrigated land, and canals and ditches.
Physalaemus cuvieri is a species of frog in the family Leptodactylidae. It is found in Argentina, Brazil, Paraguay, and possibly also Bolivia, Guyana, Uruguay, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests, moist savanna, subtropical or tropical dry lowland grassland, subtropical or tropical seasonally wet or flooded lowland grassland, intermittent freshwater lakes, intermittent freshwater marshes, arable land, pastureland, plantations, rural gardens, urban areas, heavily degraded former forest, ponds, irrigated land, seasonally flooded agricultural land, and canals and ditches. It is threatened by habitat loss.
Physalaemus deimaticus is a species of frog in the family Leptodactylidae. It is endemic to Brazil and only known from its type locality in Jaboticatubas, Serra do Cipó, Minas Gerais. The specific name deimaticus is derived from Greek deimos fror "fear" and refers to the defensive display of this frog, probably aimed at scaring predators. Common names Jaboticatubas dwarf frog and frightening foam froglet have been coined for it.
Physalaemus ephippifer is a species of frog in the family Leptodactylidae. It is found in central and eastern Brazilian Amazonia, the Guianas, and southern Venezuela. It might not occur in French Guiana.
Physalaemus erikae is a species of frog in the family Leptodactylidae. It is endemic to eastern Brazil and currently known only from southern Bahia, although it is likely that its range extends into nearby areas in northeastern Minas Gerais and northern Espírito Santo with similar vegetation.
Physalaemus gracilis is a species of frog in the family Leptodactylidae. It is found in southern Brazil, Uruguay, and adjacent Argentina, and likely also in Paraguay. Its natural habitats are forest borders and Cerrado grasslands. It is an adaptable species that also occurs in heavily disturbed and polluted habitats. It breeds using foam nests in natural temporary pools. This abundant and widespread species is not facing major threats.
Physalaemus maculiventris is a species of frog in the family Leptodactylidae. It is endemic to Southeast and South Brazil and is known primarily from the Serra do Mar in Espírito Santo, Rio de Janeiro, São Paulo state, Paraná, and Santa Catarina states. Common name Mantagnes dwarf frog has been proposed for it.
Physalaemus moreirae is a species of frog in the family Leptodactylidae. It is endemic to the Serra do Mar in the São Paulo state, Brazil.
Physalaemus olfersii is a species of frog in the family Leptodactylidae. It is endemic to southeastern Brazil and is known from Espírito Santo, southeastern Minas Gerais, and São Paulo states. Records further south refer to Physalaemus lateristriga, which was restored from the synonymy of Physalaemus olfersii in 2010. Common name Atlantic Forest dwarf frog has been proposed for this species.
Physalaemus riograndensis is a species of frog in the family Leptodactylidae. It is found in Argentina, Brazil, Paraguay, and Uruguay. Its natural habitats are subtropical or tropical seasonally wet or flooded lowland grassland, freshwater marshes, intermittent freshwater marshes, arable land, pastureland, ponds, seasonally flooded agricultural land, and canals and ditches.
Physalaemus soaresi is a species of frog in the family Leptodactylidae. It is endemic to southeastern Brazil where it is only known from three localities in the Rio de Janeiro state, one of them lost to urbanization and habitat degradation.
Engystomops freibergi is a frog native to the Amazonian Brazil, southeastern Peru, and Amazonian Bolivia. For a while, it was considered to be a synonym of Engystomops petersi, its sibling species, but its species status was resurrected in a study published in 1998. Nevertheless, these two species have also been mixed in later studies, and there are records from the Guianas that have not yet been allocated to either species. Divergence of these two species seems to have been driven by behavioural isolation related to male call characteristics more than geographic isolation.
