Bocaina Tree Frog, perereca-verde
|Taxonomic Notes: Berneck, Haddad,Lyra, Cruz and Faivovich [2016 Mol Phylog Evolution 97:213-223] show that topotypic specimens of Aplastodiscus albosignatus and Aplastodiscus callipygius are almost identical in studied DNA sequences and the taxa are inter-nested in phylogenetic analysis. The taxa are also morphologically similar. Accordingly, A. callipygius is treated as a junior synonym of A. albosignathus. AmphibiaWeb has a species account for A. albosignatus written in English and another for A. callypigius written in Portuguese. We have photographs attributed to both putative taxa. Everything is now presented as A. albosignatus, but readers should be aware of the need to revise the species accounts. AmphibiaWeb welcomes such a revision, in either English and Portuguese, or preferably both.|

The tadpole was described by Gomes (1996): body oval in dorsal view, nares reniform, spiracle sinistral, vent tube dextral, caudal muscle well-developed, oral apparatus ventral, LTRF 2(2)/4(1), a single layer of marginal papillae, submarginal papillae present.
The general dorsal color is green, as well as the muscles and bones.
Distribution and Habitat
Life History, Abundance, Activity, and Special Behaviors
The tadpoles are benthic and can be found in narrow streams, with clay bottoms. Newly metamorphosed froglets are 21 mm in SVL and have some black spots on the dorsum (Gomes 1996).
Defense strategies include body lifting, distress calls and camouflage (Haddad et al. 2008).
