Family Brachycephalidae

Brachycephalus bufonoides and B.garbeanus were ressurrected from synonymy with B. ephippium and validated as full species (Pombal, 2010).

The species listed as “ Eleutherodactylus gr. lacteus (Miranda‑Ribeiro, 1923)” by Rocha et al. (2004) is probably meant to be Ischnocnema lactea . This species is problematic, however, and needs to be reviewed in order to define its actual status and geographic distribution (T. Silva‑Soares, pers. comm.). As I. lactea was described from a site in the state of São Paulo and attribution of this name to other populations at present is considered problematic, we exclude this species from the list pending resolution of its taxonomic status.

Ischnocnema nigriventris ( Lutz, 1925) was originally described based on specimens from “Serra de Cubatão” (state of São Paulo) and“Itatiaia” (state of Rio de Janeiro) ( Lutz, 1925). Presumably based on the latter record, the species was included in the list of Rocha et al. (2004). Since then, Berneck et al. (2013) have reviewed the species based on the existing syntypes and on newly collected material, concluding that I. nigriventris occurs only in the state of São Paulo. Berneck et al. (2013) argue that the record from Itatiaia was based on a specimen that is presently lost, and apparently not conspecific with the remaining syntypes (as previously suggested by Heyer, 1985). Thus, we herein remove this species from the list of amphibians occurring in the state of Rio de Janeiro.
