Abstract
Amazophrynella is a genus of the family Bufonidae, currently represented by three species.
The type species of the genus,Amazophrynella minuta, however, is a complex of species occurring throughout the Amazonian biome.
This group remains
problematic taxonomically; the difficulty lays principally in the lack of diagnostic characters in the original description
of A. minuta, the lack of molecular data and refined taxonomic comparison of individuals through its wide
distribution. We describe a new species of the genus Amazophrynella, distributed in the southwestern part of the Guiana
Shield of Brazil based on a series of morphological and molecular characters.
