Redescription of the Amazonian tiny tree toad Amazophrynella minuta (Melin, 1941) (Anura: Bufonidae) from its type locality

The description of Amazophrynella minuta was published in 1941 by the Swedish naturalist Douglas Melin based on ma-terial from Taracuá (Amazonas state, Brazil). This description was very brief and based on the morphology of few speci-mens with diagnostic characters and color variation not well defined. Moreover, the type series is currently in poor state of conservation. Consequently, taxonomic ambiguity surrounds the nominal taxon A. minuta, which hampers the descrip-tion of many unnamed congeneric species. Herein, we redescribe A. minuta based on recently collected specimens from the type locality, designate a lectotype, formulate a new diagnosis, provide patterns of morphological variation, measure-ments and body proportions.
