RESUMO:

Biological collections represent sources of information about the species and places
where they live.They are files of great importance to the research, bringing different types of
information that produces history of the ecosystem sampled over time. When properly
catalogued an acoustic recording acquires scientific value, with technical information and
related biological. Acoustic signals are used by organisms such as anuran amphibians, being
essential for communication between groups that carry information about the identity, size,
location and sexual status of the issuer.The objective of this work was to describe the spatial
and temporal representativeness of the biological collections that house the The biological
collections that house the specimens and/or ecordsspecimens and/or records of audio recordings
of anuran amphibian species that were described for the Neotropical region duringth records of
audio recordings of anuran amphibian species that were described for the Neotropical region
during the 21st century.This information is presented compiled on primary type specimens for
1,007 anura amphibian species. Such information was compiled in the website database
Amphibian Species of the World, that through the application of filters, the list of species
described between 2000 a 2020 and overseas territory: Argentina, Bolivia, Brazil, Chile,
Colombia, Ecuador, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay and
Venezuela The types were located with their respective acronyms. We obtained the results that
most type species are deposited in the same country país (752 ssp.) Together we evaluate the
respective descriptions and collections in which the advertising corners of these species were
deposited.Our results show that the descriptions of Corners in relation to the types described
are at a level of 50% compared to the descriptions of the Species.That is; we obtained 51%
species to 48% Corners described and 1% of corners described twice. Regarding the
representativeness of holotypes of South American species, we identified that nine countries
outside South America they hold these holotypes, which are in developed countries such as
Europe, Ecuador and Cuba. Whose songs have also been described outside the South America.
In this work there are gaps of knowledge in relation to the descriptions of anuran calls from
South America, since there are more species destined to traditional collections than species
being destined for acoustic collections (fonotecas).Since there is not a great distance of time
between the described species and their respective songs.
