Thoropa is a genus of frogs in the family Cycloramphidae. [1] [2] They are endemic to eastern and southeastern Brazil. They are sometimes known as river frogs. [1]

Description, ecology, and behavior

Thoropa are associated with rocks and have cryptic coloration. Their size ranges from small to medium, 28–102 mm (1.1–4.0 in) in snout–vent length. [3] They occur at elevations up to 1,500 m (4,900 ft) above sea level; [3] Thoropa miliaris and Thoropa taophora can even live on rocky marine shores, foraging in the intertidal zone. [4] [5] Male Thoropa are associated with wet rock faces, whereas the females seem to range more widely. [6]

In species where reproduction is known, males are territorial—suitable wet rock faces are a scarce resource. Furthermore, mature male Thoropa feature characteristic clusters of dark spines on the inner portions of the hand. It appears that these are associated with male-male combat, probably in conjunction with territorial disputes. Scratch marks in males, but not in females, support this interpretation. [6]

The eggs are laid on rocks with a thin layer of water. Tadpoles are semiterrestrial and have a depressed shape, long tail, and bulging eyes. [3]

Male T. taophora frogs mate exclusively and repeatedly with two females per season in a polygynous system in which the semiterrestrial tadpoles from both females share the same freshwater seep. [7] The females have a dominance hierarchy, and the males mate more with the dominant female. [7]

Eleutherodactylidae Family of amphibians

The Eleutherodactylidae are a family of direct-developing frogs native to northern South America, the Caribbean, and southernmost North America. They are sometimes known under the common name rain frogs. Formerly the subfamily Eleutherodactylinae of the family Leptodactylidae, it was raised to the family status following a major revision of New World direct-developing frogs in 2008. As currently defined, the family has more than 200 species.

Cycloramphidae Family of amphibians

The Cycloramphidae are a family of frogs endemic to southeastern Brazil. This family has seen large changes in its composition. Genera that have at some point been included in the Cycloramphidae are at present placed in the Alsodidae, Hylodidae, Leptodactylidae, and Rhinodermatidae. Of these, the Alsodidae and/or Hylodidae have also been considered as subfamilies of Cycloramphidae ; the Cycloramphidae, as recognized at present, would be similar to subfamily Cycloramphinae under such system.

<i>Physalaemus</i> Genus of amphibians

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 rescribed Leptodactylus lauramiriamae is in some aspects intermediate between them.

<i>Leptodactylus</i> Genus of amphibians

Leptodactylus is a genus of leptodactylid frogs. It includes the species commonly called ditch frogs or white-lipped frogs. It is very similar to Physalaemus, a close relative, and indeed the recently described Leptodactylus lauramiriamae is in some aspects intermediate between them. The name means ‘slender finger’, from leptos (‘thin, delicate’) and the Greek daktylos.

<i>Cycloramphus</i> Genus of amphibians

Cycloramphus is a genus of frogs in the family Cycloramphidae. The genus is endemic to the southeastern Brazil. They are sometimes known as the button frogs.

It is endemic to southern Brazil and occurs in the Santa Catarina and Rio Grande do Sul states, corresponding to the southernmost extent of the Atlantic Forest biome. The specific name saxatilis refers to its association with rocks. Common name Brazilian river frog has been coined for it.

Arthroleptides is a small genus of frogs in the family Petropedetidae. Their common name is rocky river frogs. They are found in the mountains of East Africa. They have been considered to belong to Petropedetes, which after exclusion of Arthroleptides is restricted to Central Africa.

<i>Petropedetes cameronensis</i> Species of frog

The Alsodidae are a small family of frogs from South America between Patagonia and southern Brazil. It contains 30 species in three genera. This family, along with several other families, used to be included in the family Leptodactylidae. It was then a subfamily in the family Cycloramphidae, before being recognized as a family first in 2011.

<i>Beddomixalus</i> Genus of amphibians

Beddomixalus is a monotypic genus of frogs in the family Rhacophoridae. The only described species, Beddomixalus bijui, is endemic to the Western Ghats, India. Its name is derived from a combination of the cognomen of Richard Henry Beddome, in honour of his work on the amphibian diversity of the Western Ghats, as well as Ixalus, which is often used as a suffix for names of rhacophorid genera.
