Sphaenorhynchus is a genus of frogs in the family Hylidae. They are also known as lime treefrogs or hatchet-faced treefrogs.

The majority of the species are associated with the Atlantic Forest domain in Brazil.
The Pine Barrens tree frog is a species of New World tree frog. It is becoming rare due to habitat loss.
The spotted chorus frog or Clark's tree frog is a small, nocturnal chorus frog native to the grasslands and prairies of the central United States and Tamaulipas, Mexico.
Ambystoma talpoideum, the mole salamander, is a species of salamander found in much of the eastern and central United States, from Florida to Texas, north to Illinois, east to Kentucky, with isolated populations in Virginia and Indiana. Older sources often refer to this species as the tadpole salamander because some individuals remain in a neotenic state. This salamander lives among the leaf litter on the forest floor, migrating to ponds to breed.
The Vietnamese pond turtle or Annam leaf turtle is a species of turtle in the family Geoemydidae.
The striped newt is a species of aquatic salamander native to the southeastern United States. It is a close relative of the eastern newt, with which it shares territory, and can be distinguished from the latter by the presence of red stripes running down the sides of its back and red spots on its back that lack a black outline.
Scinax squalirostris is a species of frog in the family Hylidae. It is found in southeastern, southern and central Brazil, Uruguay, northeastern Argentina, southern Paraguay, and Bolivia. The nominal species might actually represent more than one species. Common names striped snouted treefrog and long-snouted treefrog have been coined for it.
Sphaenorhynchus bromelicola, the Bahia lime treefrog, is a species of frog in the family Hylidae. It is endemic to eastern Brazil and only known from its type locality near Maracás, Bahia. It is similar to Sphaenorhynchus orophilus. It lives in terrestrial bromeliads on the forest edge and in open areas. The tadpoles develop in permanent pools. It is abundant at the type locality. Potential threats to this species include habitat loss caused by agriculture, wood plantations, logging, collection of bromeliads and human settlement, though data is insufficient to grant it conservation status.
Sphaenorhynchus dorisae, the Doris' lime treefrog, is a species of frog in the family Hylidae. It is found in the upper Amazon Basin of southeastern Colombia, Ecuador, Brazil and Peru. It might also be present in Bolivia.
Sphaenorhynchus lacteus, the Orinoco lime treefrog or greater hatchet-faced treefrog, is a species of frog in the family Hylidae. It is a widely distributed species found in the Orinoco and Amazon basins in Venezuela, the Guianas, Colombia, Brazil, Ecuador, Peru, and Bolivia. It also occurs in Trinidad and Tobago.

It is endemic to south-eastern Brazil where it occurs in the Serra do Mar and Serra da Mantiqueira ranges in the states of Rio de Janeiro, São Paulo, and Minas Gerais. However, Araujo-Vieira and colleagues suggests that the Serra da Mantiqueira population could represent Sphaenorhynchus canga; the two species are similar.

Sphaenorhynchus surdus, or Cochran's lime treefrog, is a species of frog in the family Hylidae. It is endemic to southern Brazil and is known from the eastern Paraná, Santa Catarina, and northeastern Rio Grande do Sul states. Before Sphaenorhynchus caramaschii was described in 2007, all Sphaenorhynchus from the south of the state of São Paulo state all way south to Rio Grande do Sul were identified as S. surdus.
