A chromogenetic field analysis was performed with 25 of 29 of the known species of the genus Callicebus. Some species presented polymorphism, such as C. moloch, C. hoffmansii and C. cupreus. C. bernhardi presents the same distribution of color in chromogenetic fields as C. moloch, differing only in pigment amount, mainly in ventral surfaces, suggesting C. bernhardi is a junior synonym of C. moloch. C. hoffmansii presents two distinct phenotypes, but without a geographic barrier between them. Callicebus cupreus, C. dubius and C. caligatus are distinct species.Key Words: Callicebus, taxonomy, phenotypical polymorphism ResumoUma revisão taxonômica baseada nos campos cromogenéticos foi procedida em 25 das 29 espécies conhecidas do gênero Callicebus. Algumas espécies apresentaram polimorfismo como C. moloch, C. hoffmansii e C. cupreus. Callicebus bernhardi apresenta o mesmo padrão de distribuição de campos cromogenéticos de C. moloch, divergindo somente na quantidade de pigmentos, principalmente na face ventral da pelagem. Assim, C. bernhardi deve ser considerado sinônimo júnior de C. moloch. C. hoffmansii apresenta dois fenótipos distintos, porém não há uma barreira geográfica entre eles. C. cupreus, C. dubius e C. caligatus são espécies distintas.

Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non‐detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non‐governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer‐reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non‐detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio‐temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large‐scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data.

The Gurgueia River in southern Piauí state, Brazil, is the largest affluent on the right margin of the Parnaíba River basin. This study aimed to inventory the Gurgueia River ichthyofauna, and contribute to the knowledge of fish diversity in Northeastern Brazil. We sampled 71 locations throughout the Gurgueia sub-basin between 2006 and 2014, which resulted in 90 fish species representing 67 genera, 26 families and six orders, including two non-native species. Six species are newly recorded for the Parnaíba basin (Hasemania nana, Hemigrammus brevis, H. guyanensis, H. ora, Corydoras sp. and Cetopsorhamdia sp.), increasing its freshwater ichthyofauna to 152 species. The Gurgueia River contains 59.2% of the ichthyofauna known for the Parnaíba basin, and can be used as a reference point for the establishment of priority areas for the conservation of the freshwater fish fauna of the Brazilian Northeast.

Many aspects of the Brazilian fauna dynamics remain unknown. Often, researches on zoology depend on invasive protocols that require the death of specimens of rare or endangered species. This is the first time a combined protocol is proposed for the use of roadkill or stranded animals in research and teaching by different professionals. It turns such undesired deaths into a source of taxonomic material, tissue for histology, DNA analysis and parasitological tests and as ecological evidence. This is a non-invasive protocol that requires no sacrifice of any specimens. Skins and skeletons can be processed as taxonomic material and stomach contents provide information about feeding habits and ecology. In addition, regional zoological collections can be improved and these specimens can be used for practical classes in different areas, including environmental conservation. This article thus describes thirteen steps which can be taken to take the best advantage of these victims of human progress.
