Taxonomy
Amazophrynella was separated from Dendrophryniscus in 2012 based on molecular genetic evidence that indicated deep divergence between an Amazonian and an Atlantic Forest clade, the latter retaining the name Dendrophryniscus whereas the former was described as a new genus Amazonella, later amended to Amazophrynella because of homonymy.
Description
Dendrophryniscus are small to medium-sized toads measuring 15–47 mm (0.59–1.85 in) in snout–vent length. Their body form resembles that of Atelopus. The hind limbs are well developed. The parotoid glands are absent, as are external tympana. The skin is uniformly granulose to warty. Dorsal coloration is cryptic.
With the exception of Dendrophryniscus leucomystax, Dendrophryniscus breed in phytotelmata. In contrast, Amazophrynella are pond breeders, which is presumably an ancestral trait in bufonids.
Species
