“…A collared titi, Cheracebus aquinoi was described by Rengifo et al (2023) using morphological (cranial and pelage) and molecular (mitochondrial DNA) evidence. It occurs between the rıós Nanay and Tigre, south of the Rio Napo, in Peru.…”

The database of the IUCN SSC Primate Specialist Group currently (December 2023) registers 218 species and subspecies of Neotropical primates in 24 genera and five families. In the early 1960s, the diversity of Neotropical primates was estimated to be around 200 species and subspecies. From then, through the 1970s to the mid-1990s, however, the perception of the region’s primate diversity dropped, and reached an all-time low at 83 species and subspecies in 1980 (A World List of Mammalian Species, G. B. Corbet and J. E. Hill, British Museum (Natural History), Comstock Publishing, Cornell University Press, London and Ithaca). Interest in taxonomy and primate field research in the Neotropics was subdued up to the late 1970s. Change was sparked by the burgeoning capture of primates for biomedical research in the 1950s and 1960s, and the increasing destruction of the Amazon rainforests from the late 1970s. The numbers increased, at first slowly, but then, in 1995, they leapt back to the 200s in anticipation of a book by C. P. Groves (2001, Primate Taxonomy, Smithsonian Institution Press, Washington, DC). The species’ counts (not including subspecies) rose due to the adoption of the Phylogenetic Species Concept over the Biological Species Concept, the former favoring the category of species over subspecies. In this article, we discuss the changes in species and subspecies numbers in the classification of the Neotropical primates, and report on the taxonomic changes resulting from taxonomic research ongoing since 2012. We emphasize the importance of taxonomic research for an understanding of the diversity of primates, and for conservation planning, not least in identifying the populations that are threatened.

“…Our results are partially congruent with Šmíd (2022), which pointed out that the Northern Amazon is one of the best represented portions of the world for mammals, but are discordant with the results in comparison with the western Amazon, which was one of the poorest represented areas in our study. This might be related with an increase in the availability of distribution maps for mammals and newly described species (Marsh et al 2022;Rengifo et al 2022), which revealed more specific regional patterns for species that were not considered in Šmíd (2022).…”

DNA barcoding and environmental DNA (eDNA) represent an important advance for biomonitoring the world's biodiversity and its threats. However, these methods are highly dependent on the presence of species sequences on molecular databases. Brazil is one of the largest and most biologically diverse countries in the world. However, many knowledge gaps still exist for the description, identification, and monitoring of its mammalian biodiversity using molecular methods. We aimed at unraveling the patterns related to the presence of Brazilian mammal species on molecular databases to improve our understanding on how effectively it would be to monitor them using DNA barcoding and environmental DNA, and contribute to the conservation of this flagship zoological group. We found that many gaps exist in molecular databases, with many taxa being poorly represented, particularly from the Amazon biome, the order Lagomorpha, and arboreal, gomivorous, near extinct, and illegally traded species. Moreover, our analyses revealed that the year of species description was the most important factor determining the probability of a species to have been sequenced. Primates are the group with the highest number of species considered to be priority for sequencing due to their high level of combined threats. We highlight where investments are needed to fill knowledge gaps and increase the representativity of species on molecular databases to enable a better monitoring ability of Brazilian mammals encompassing different traits using DNA barcoding and environmental DNA.
