Psychrophrynella bagrecito is a species of frog in the family Strabomantidae. It is endemic to the Cusco Region, Peru, and found on the Amazonian slopes of the Andes at elevations of 1,830–2,740 m (6,000–8,990 ft) asl.

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.

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.

Common name Atlantic Forest dwarf frog has been proposed for this species.
Engystomops petersi is a species of frog in the family Leptodactylidae. It is found in Amazonian Colombia, Ecuador, and Peru. It is morphologically similar to its sibling species, Engystomops freibergi, and for a period the latter was considered to be a junior synonym of Engystomops petersi. Taxonomy and classification of this species is constantly changing due to the continual evolution of behavioral isolation and rapid speciation in the region. There are also 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.
Engystomops pustulatus is a species of frog in the family Leptodactylidae. It is known with certainty from western Ecuador, whereas the status of Peruvian records is ambiguous as they may refer to an undescribed species or possibly Engystomops puyango. Nevertheless, given that E. pustulatus is now known from Huaquillas in southern Ecuador, near the Peruvian border, it is likely to be found in Peru too.
The Túngara frog is a species of frog in the family Leptodactylidae. It is a small nocturnal terrestrial frog found in Mexico, Central America, and the northeastern regions of South America.
