The Guía de identificación de fauna silvestre para las autoridades ambientales de Amazonas, San Martín, Loreto y Ucayali (ISBN: 978-612-4261-24-4) was published in order to provide a tool for authorities related to the fight against wildlife trafficking and trade.This guide represents an important tool, so the information transmitted should be as current and reliable as possible. However, after reviewing the section dedicated to mammals, we identified several errors that could generate confusion and be counterproductive in the fight against wildlife trafficking. Although we emphasize the importance of this work, we suggest caution in the preparation of documents such as this guide in order to maximize its usefulness for the authorities that fight wildlife trafficking in our territory.

Con la finalidad de brindar una herramienta para autoridades vinculadas a la lucha contra el tráfico ilegal de fauna silvestre se publicó la Guía de identificación de fauna silvestre para las autoridades ambientales de Amazonas, San Martín, Loreto y Ucayali (ISBN: 978-612-4261-24-4). Esta guía representa una herramienta importante por lo cual la información transmitida debe ser lo más actual y fidedigna posible. Sin embargo, después de revisar la sección dedicada a mamíferos, identificamos diversos errores que podrían generar confusión y ser contraproducentes en la lucha contra el tráfico ilegal de vida silvestre. Aunque resaltamos la importancia de este trabajo, sugerimos precaución en la elaboración de documentos como esta guía con la finalidad de maximizar su utilidad para las autoridades que combaten tráfico de fauna en nuestro territorio.

The Saki monkeys, genus Pithecia Desmarest, 1804, have undergone drastic taxonomic changes in a 2014 revision of the genus. In this revision, Pithecia hirsuta Spix, 1823 and P. inusta Spix, 1823 were considered as valid, although both species have been widely considered synonymous with P. monachus. Nonetheless, here we demonstrate, by reviewing the original descriptions of both species, that P. inusta cannot be applied to the Peruvian populations of Pithecia inhabiting primarily the Ucayali River watershed since the original concept of this species, as well as its type locality did not include its putative geographic range. In fact, the area falls completely outside the expedition's itinerary that collected the holotype. Thus, to preserve stability until further evidence is furnished, the above-mentioned Pithecia populations should be regarded as P. monachus.   

Los muriquis, género «Brachyteles» Spix, 1823, son miembros de la subfamilia Atelinae junto con «Ateles» y «Lagothrix». «Brachyteles» fue tratado inicialmente como monotípico y actualmente dos especies son reconocidas, «B. arachnoides» (muriqui del sur) y «B. hypoxanthus» (muriqui del norte). Estas dos especies tienen como diagnosis la región facial totalmente pigmentada de negra y ausencia de pulgar en los muriquis sureños, mientras que las poblaciones norteñas presentan caras moteadas de rosado y pulgar totalmente desarrollado. Adicionalmente, las relaciones filogenéticas entre los atelinos es disputada. En cuanto la evidencia morfológica apunta a un clado («Lagothrix» [«Ateles» + «Brachyteles»]), la molecular sugiere un arreglo diferente («Ateles» [«Brachyteles» + «Lagothrix»]). Luego de realizar análisis cualitativos de caracteres morfológicos externo...

This work summarizes recent knowledge regarding the diversity and distribution of 11 Orders of mammals from Peru. Species information is presented for the country, ecoregions and, for the first time, by individual departments. Furthermore, we identified endemic species for the country and provided elevation ranges per species. To compile our information, we conducted an exhaustive review of the scientific literature and specimens in scientific collections, consulting with specialists when needed to verify records. We report 191 species belonging to the orders Didelphimorphia (46 spp.), Paucituberculata (2), Sirenia (1), Cingulata (5), Pilosa (8), Primates (42), Lagomorpha (2), Eulipotyphla (3), Carnivora (33), Perissodactyla (2), and Artiodactyla (47, including 32 cetaceans); 22 of these are endemic to Peru. Due to their high diversity and number of taxonomic changes, the Orders Chiropte...
