Proceratophrys schirchi
"Proceratophrys schirchi" and "Proceratophrys precrenulata" were described by Alípio de Miranda Ribeiro in 1937 in the same paper. There has been discussions whether these two species are distinct. In 1997, Caramaschi and Ulisses argued that the distinguishing character between "P. schirchi" and "P. precrenulata"—the apparent absence of tubercles on the upper eyelids in the former—was not real but attributable to the poor preservation of the types. The type series of both taxa were collected from the same locality. This led Caramaschi and Ulisses to argue that "P. schirchi" and "P. precrenulata" are the same species, and chose "P. schirchi" as the valid name because the type series of "P. precrenulata" is lost and "P. schirchi" appeared first in the publication in which both were described. Adult males measure in snout–vent length. The eyelids have a row of enlarged, pointed tubercles. The snout is truncate. "Proceratophrys schirchi" occurs in primary and secondary forest at elevations below ; is not found outside forest. It is a leaf-litter species living on the forest floor. Breeding takes place in small forest streams. It is a common species, but habitat loss caused by agriculture, wood plantations, livestock grazing, human settlement, fire, and logging is a threat. It is found in several protected areas.
