Family Bufonidae Gray, 1825

Remarks: Frost et al. (2006) proposed a monophyletic taxonomy for several bufonid clades, such as Rhaebo for the Bufo guttatus species group, Rhinella for the Bufo margaritifer species group, and Chaunus for a number of other South American species groups of Bufo . Chaparro et al. (2007) embedded the genus Chaunus within Rhinella . Bufo nasicus shown to be basal to Rhaebo by implication; however, implication is not a resolution, but merely implicates the need for elucidation and further evidence. Barrio-Amorós (2009) supposed Bufo nasicus to be a member of Rhinella based on external characters and transferred it to that genus without further clarification. Barrio-Amorós and Castroviejo-Fisher (2008a) considered Rhaebo anderssoni a synonym of R. guttatus . Genus Dendrophryniscus Jiménez de la Espada, 1870 was split by Fouquet et al. (2012a), and the Amazonian-Guianan clade was then named Amazonella . Fouquet et al. (2012b) realized that Amazonella was a preoccupied unavailable name according to the Code and proposed Amazophrynella as a replacement name for the clade.
