| The Saguinus represent the basal genus of the Callitrichinae subfamily. Traditionally this genus is divided into three groups: Hairy, Mottled and Bare-face, however, molecular data failed to validate these groups as monophyletic units, as well as raised some subspecies to the species status. This is the case of the former subspecies Saguinus midas midas and S. midas niger, which are now considered as different species. In the present study, we sequenced a portion of the D-loop mtDNA region in populations from the East bank of the Xingu and from both banks of the Tocantins river, in order to test the effectiveness of large rivers as barriers to the gene flow in Saguinus. According to our results, the populations from the East and West banks of the Tocantins... |

| The phylogenetic proximity of primates to humans, along with their behavioral, biochemical, and anatomical similarities, make such animals more interesting experimental models for biomedical researches, as compared to classical laboratory animals. Another aspect that has called the attention of researchers is the differentiated quadrupedalism present in some primates. The tufted capuchin monkey uses the ground and tree branches as its support for locomotion, showing various postures while performing this task. On the basis of this information, we have decided to study the rectus abdominis muscle of the tufted capuchin monkey, with the following goals: the frequency and area of fiber types; its possible compartmentalization; and identify if this muscle is... |

| Los monos neotropicales de la colección del Zoológico de la Ciudad de Mendoza (ZMA), Argentina, fueron objeto de un estudio colaborativo que incluyó la toma de medidas antropométricas y el análisis citogenético básico (alfa). Se estudiaron 13 ejemplares del género Alouatta sp. (10 hembras y 3 machos), 2 Cebus sp. (una hembra y un macho) y 3 hembras Saimiri sp. Mediante la cariología se confirmó que los Cebus del ZMA se corresponderían con C. paraguayanus (2N=54, XX/XY) y los Saimiri, con Saimiri boliviensis boliviensis (2N= 44,XX). En los aulladores se corroboró su asignación de especie como A. caraya y se observó una morfología cromosómica, compatible con el ya descrito sistema de determinación sexual múltiple X1X1X2X2/X1X2Y1Y2. La oportunidad permitió... |

| Estudiar las características de variabilidad genética, organización social y biogeografía, permite nuevas interpretaciones del proceso especiogénico. En Primates en particular, en los 80, se desarrollan los primeros estudios citogenéticos en Argentina, empleando tinción estándar, bandas G, C y NOR, citogenética en vigencia en aquella época. Se caracterizan Cebus sp., Saimiri boliviensis, Aotus azarae y Callithrix jacchus (Cebidae); Ateles sp., Alouatta sp. (Atelidae) por ser las especies más frecuentes en zoológicos y bioterios. Al igual que en ejemplares de especies de nuestra fauna analizados por muestreo en vida silvestre, se estableció 2N y patrones de bandas G y C en cada especie. El análisis de reordenamientos cromosómicos comprometiendo... |

| Only seven types of mammals are known to be venomous, including slow lorises (Nycticebus spp.). Despite the evolutionary significance of this unique adaptation amongst Nycticebus, the structure and function of slow loris venom is only just beginning to be understood. Here we review what is known about the chemical structure of slow loris venom. Research on a handful of captive samples from three of eight slow loris species reveals that the protein within slow loris venom resembles the disulphide-bridged heterodimeric structure of Fel-d1, more commonly known as cat allergen. In a comparison of N. pygmaeus and N. coucang, 212 and 68 compounds were found, respectively. Venom is activated by combining the oil from the brachial arm gland with saliva, and can... |

| O zogue-zogue cinza escuro (Callicebus cinerascens; Primates; Pitheciidae) é uma das espécies menos estudadas entre os primatas neotropicais, ocorrendo nos interflúvios Aripuanã-Roosevelt e Tapajós-Juruena, na Amazônia Brasileira. Os limites de sua distribuição, especialmente os limites leste e sul, ainda são desconhecidos. Baseado em quatro inventários de primatas distintos, nós mostramos várias novos registros de ocorrência desta espécie ao sul de sua distribuição geográfica. O conhecimento sobre primatas silvestres nesta região é completamente ausente. Estas populações recentemente descobertas estão sobre severa ameaça, uma vez que os remanescentes de florestas nativas encontram-se altamente fragmentados devido ao grave histórico de desmatamento da... |

| The colobine monkey Presbytis comata is confined to the rain forests of West and Central Java, Indonesia. In order to determine its distribution, a review of the literature, evidence from the study of museum specimens, and the results of recent surveys are presented. Recent surveys in the central parts of the island indicate that P. comata is still present on four volcanic mountain complexes, viz. Mt. Sawal, Mt. Slamet, Mts. Dieng, and Mt. Lawu. The present paper gives the results of the surveys combined with a review of its distribution. Altitudinal and habitat preferences, and the conservation status of the species are discussed. |

| As one of the fundamental units of ecology and biogeography, the geographic distribution of the endemic and threatened ebony leaf monkey Trachypithecus auratus (E. Geoffroy Saint-Hilaire, 1812) on the islands of Java, Bali, and Lombok (Indonesia) has been assessed. All localities where the species has been collected are listed, and forty-two areas (each in itself consisting of numerous smaller sites) where the species has been recorded are discussed. The species occurs in a large variety of forest types, including mangrove, beach, and freshwater swamp forest; everwet lowland and hill forest; dry decidious forest; montane forest up to 3,000 – 3,500 m a.s.l.; and in some forest plantations (teak Tectona grandis, rasamala Altingia excelsa, acacia Acacia spp).... |

| Titi monkeys (Callicebus), morphologically cryptic primates, have been difficult to survey using traditional sighting-based line transect methods. Callicebus-species regularly engage in loud, ritualized singing bouts, which could allow for the use of alternate, potentially more accurate call-based survey methods to monitor populations. The Andean titi monkey, C. oenanthe, is endemic to a small region of northern Peru, an area subject to widespread and rapid deforestation and human colonization. We conducted a call-based survey of C. oenanthe at Tarangue, a 74 ha private reserve near Moyobamba. Triangulation of calls was used to map groups of titi monkeys on and around the reserve. 73 mapped calls were used to estimate the presence of between three and... |

| Hose’s leaf monkey Presbytis hosei is endemic to Borneo and occurs only in tall forest. In recent decades Borneo has lost a large part of its forest cover, mostly in low-lying coastal regions. Large intact tracts of forest remain in the interior, but these are by and large inhabited by tribes that subsist in part by hunting. The combined effects of habitat disturbance and hunting on the densities and biomass of Hose’s leaf monkey were studied in Kayan Mentarang National Park in Borneo’s far interior. Over four months, data on densities and hunting were collected by transect walks in four forest types. Hose’s leaf monkeys were hunted to deter crop-raiding, for their meat, and to obtain bezoar stones (visceral secretions used in traditional medicine). Hose’s... |

| The potto was first recorded and figured by Willem Bosman in 1704. The name Lemur potto Statius Müller, 1776 is exclusively based upon Bosman’s account and figure, which are reproduced in full. The type locality is Elmina on the Gold Coast, the present Ghana. No type specimen was collected. The early pottos in the Leiden Museum are listed and their history is given, with special reference to the animals obtained by H.S. Pel. The publications on this material are reviewed. An adult female, RMNH 39375: mounted skin and skeleton acquired by Pel in 1849 at Dabocrom (Dabo Krom) near Sekondi, coastal Ghana, is designated the neotype of Lemur potto Statius Müller, 1776. The neotype is extensively described and figured. Taxonomic notes on the putative (sub)species... |

| ABSTRACT Alouatta guariba clamitans Cabrera, 1940 is an endemic species of the Atlantic Forest that occurs from south Bahia, Brazil, extending south to the province of Misiones, Argentina. In Rio de Janeiro state, the species was classified as threatened, indicating that attention is needed for the conservation of this taxon. Additionally, an outbreak of yellow fever spread throughout the southeastern states of Brazil from January 2017 until March 2018 seriously threatening Rio de Janeiro populations of the species. Herein, we aimed to provide the first estimates of A. g. clamitans encounter rate, density, and population size in the Ilha Grande State Park (PEIG), which is part of the Atlantic Forest biome of Brazil. Data were collected in two different... |

| Prey foraging behavior in the Black Lion Tamarin, Leontopithecus chrysopygus (Mikan, 1823) was observed in the Caetetus Ecological Station, southeastern Brazil, during 550 hours of direct observations between December 1993 and February 1995. The scan sampling method was used to gather data. These tamarins use manipulative, specific-site foraging behavior. When searching for animal prey items, they examine a variety of microhabitats. The most important microhabitat used for prey foraging behavior was tree cavities (41% of the foraging observations), but palm trees (22%), bamboo (12%), vines (11%), bark (5%), seed pods of the "jequitiba" tree (4%), other places (3%) and epiphytes (2%) were also observed. Animal preys were frequently captured in understory... |

| The objective of this study was to determine the size and composition of a group of wild Callithrix jacchus Erxleben, 1777, a small neotropical primate from the North East Brazil. The study was carried out in Dois Irmãos Forest, Recife, Pernambuco, Brazil, in an area of 6ha where this social group of marmosets had its home range. A graded transects system was cut to provide the access and moving during the observation period. To provide an individual identification for the members of the marmosets group and to achieve the objective of this study, two captures were made, with a six month interval between them in a 50x50m² area at the nuclear range of the group's area. The animals were realeased after a maximum period of 24h after traping. We made, during... |

| ABSTRACT The black-headed night monkey, Aotus nigriceps, has one of the largest distribution ranges of the 11 night monkey species found across Central and South America. Yet, only three studies have focused on their ecology, describing considerable variation in habitat, group composition, and population density. Therefore, we analyzed habitat use, group composition, population density, and diet of 14 groups at two field sites in southeastern Peru. All sampled groups were found in secondary tropical rainforest, often dominated by native bamboo species. Half of the observed sleeping sites were in bamboo stands, though groups also emerged from cane thickets and lianas. This contrasts with other Aotus studies which have found groups living in tree cavities... |

| Given their great variability, microsatellites or STRs became the most commonly used genetic markers over the last 15 years. The analysis of these markers requires minimum quantities of DNA, allowing the use of non invasive samples, such as feces or hair. We amplified the microsatellite Ap74 in blood and hair samples in order to analyze the levels of genomic conservation among a wide range of primates including: Lemur catta, Alouatta caraya, Ateles belzebuth, Ateles chamek, Pan troglodytes, Papio sp., and Homo sapiens. In all cases we obtained amplification products that exhibited similar size both in monkeys and human (oscillating between 126 and 176 bp), except in the lemur where the detected fragment presented a size of approximately 1000 bp. The... |
