Saguinus inustus (Schwarz, 1951) is one of the neotropical primates least studied. The distribution of the species ranges from the north of the Solimões River, between the Negro and Japurá Rivers in Brazil, and Guayabero-Guaviare Rivers in Colombia. Nevertheless, due to the low number of specimens collected from the lower Japurá and lower Negro Rivers areas, the geographic distribution is so far poorly delineated. In this study, field data was composed of sightings and the collection of specimens during a survey of mammal diversity in the Amana Sustainable Development Reserve (ASDR). For this survey, two 40-day expeditions were carried out in 2004. The first one occurred during the flooded season in June and July, and the second was during the peak of the dry season in October. Direct sightings were made through hiking along transects, navigation along water channels with a 30-hp speedboat, and gliding along flooded trails in the forest. New records of S. inustus were made in 11 different localities in ASDR. The study has confirmed the presence of the species in the Amanã area, carrying out the first records of the species in flooded forest habitats.Saguinus inustus (Schwarz, 1951) é um dos primatas neotropicais menos estudados. No Brasil, a espécie ocorre ao norte do Rio Amazonas entre os Rios Negro e Japurá (Caquetá), e Guayabero-Guaviare na Colômbia. No entanto, devido ao pequeno número de espécimes coletados entre o baixo Japurá e o baixo Negro a distribuição geográfica é mal delineada. No presente estudo, os dados de campo são compostos por observações e coletas realizadas durante o levantamento da diversidade de mamíferos da Reserva de Desenvolvimento Sustentável Amanã (RDSA). Para este levantamento, duas expedições de 40 dias foram realizadas em 2004. A primeira ocorreu durante a estação da cheia em junho e julho, e a segunda durante o pico da estação seca em outubro. Observações diretas foram feitas através de deslocamentos a pé em transecções, de lancha 30 hp ao longo de cursos d'água, e de canoas durante a cheia na área de várzea. Novos registros de S. inustus foram realizados em 11 diferentes localidades na RDSA. Este estudo confirmou a presença da espécie em Amanã, realizando os primeiros registros da espécie em florestas alagadas.

Ecological data about three free-ranging groups of C. penicillata (black-pincelled marmoset) were observed between March and December 1996, in one cerradão patch (in the Ecological Reserve of Brazilian Institute of Geography and Statistics, RECOR) and two patches of dense cerrado (one in the Recor and another in the Botanical Garden of Brasília, JBB), situated in the APA (area of environmental protection) of the Gama/Cabeça-de-Veado, Distrito Federal. Each area was visited weekly during three periods of two months -- end of the rainy season (01/04 to 31/05), dry season (16/06 to 15/08) and beginning of the rainy season (14/10 to 15/12) -- and instantaneous scan records at fifteen minute intervals were made for the vertical and horizontal position of each visible individual of the target group. The group size ranged between 4 and 11 elements. In September, the birth of twins in both groups of the Recor was observed. Home-range varied from 8.25 to 18.5 hectares, while density ranged from 0.4 to 0.82 ind/ha. Twenty two species of nine tree families were identified as exudate sources. Qualea grandiflora (Vochysiaceae), Vochysia thyrsoidea (Vochysiaceae), Scheflera macrocarpum (Araliaceae) and Qualea parviflora (Vochysiaceae) were more explored. Fruits (14 species, two of which were exotics), nectar, honey, arthropods (mainly orthopterans) and bird eggs complete their diet. The main sleep-tree species was Emmotum nitens (Icacinaceae). Data from different seasons and studied groups/areas were compared along previous data from this primate species in gallery forests. In the cerradão and dense cerrado areas C. penicillata had a similar group size, however a larger home-range and smaller density than in gallery forests were observed in this study.Entre março e dezembro de 1996 foi observada a ecologia de três grupos naturais de C. penicillata: em uma mancha de cerradão (na Reserva Ecológica do IBGE, RECOR) e em duas manchas de cerrado denso (uma na Recor e outra no Jardim Botânico de Brasília, JBB), no Distrito Federal. Cada área foi visitada semanalmente, por três períodos bimestrais -- final da estação chuvosa 1 (01/04 a 31/05), estação seca (16/06 a 15/08) e início da estação chuvosa 2 (14/10 a 15/12). Foram feitos registros de varredura instantânea a cada 15 minutos ao longo do dia para as posições vertical e horizontal de todos os animais visíveis do grupo-alvo. O tamanho dos grupos variou entre 4 e 11 membros. Em setembro, ocorreu o nascimento de gêmeos nos dois grupos da RECOR. A área domiciliar esteve entre 8,25 e 18,5 hectares e a densidade, entre 0,40 e 0,82 ind/ha. Foram identificadas 22 espécies arbóreas de 9 famílias como fontes de exsudato, das quais se destacam: Qualea grandiflora (Vochysiaceae), Vochysia thyrsoidea (Vochysiaceae), Scheflera macrocarpum (Araliaceae) e Qualea parviflora (Vochysiaceae). A dieta foi complementada por frutos de 14 espécies, néctar, mel, artrópodos (principalmente ortópteros) e ovos de aves. A principal espécie usada como árvore de pouso foi Emmotum nitens (Icacinaceae). Comparando com os dados desta espécie de primata em matas ciliares, não houve diferença quanto ao tamanho de grupo, já as áreas domiciliares foram maiores e as densidades, menores que as de matas ciliares.
