The nine allopatric species of Aotus recognized represent two natural groups distinguished by karyotype, color, and pelage patterns. Correlated with these group characters are reported differences in serum proteins and degrees of susceptibility or immunity to experimental infection with malarial parasites. The primitive gray‐neck species group of Aotus contains A. brumbacki (new species), A. lemurinus (with subspecies lemurinus and griseimembra), A. trivirgatus, and A. vociferans. The derived… 

Taxonomy of squirrel monkeys genus Saimiri (cebidae, platyrrhini): A preliminary report with description of a hitherto unnamed form

TLDR
Two groups of squirrel monkeys, genus Saimiri, are distinguished by external characters, characterized by reduction from seven to six or five paired acrocentric autosomes through pericentric inversion with reciprocal increase in number of paired submetacentric or subtelocentric autosomes.

The taxonomy of south American sakis, genus Pithecia (Cebidae, Platyrrhini): A preliminary report and critical review with the description of a new species and a new subspecies

TLDR
The report begins with a key based on external characters and a tabulation of diagnostic cranial characters for separating Pithecia from Chiropotes and Cacajao of the subfamily Pitheciinae and concludes with a discussion on nomenclature.

Identification, classification and evolution of Owl Monkeys (Aotus, Illiger 1811)

TLDR
Alternative phylogenetic reconstructions, when compared with karyotypic and biogeographic data, led to the proposition of evolutionary scenarios questioning the conventional diversification of this genus in monophyletic groups with grey and red necks.

Aotus Diversity and the Species Problem

TLDR
Karyotypic variability in Aotus suggests at least seven species in the gray-necked group based on six known karyomorphs, highly divergent mitochondrial cytochrome c oxidase sequences, different sensitivities to malaria, varied mitogenic and immunological responses to other diseases, and well-defiined geographical distributions, and the likelihood that these species are distinctive enough to possess reproductive barriers.

Revisiting the taxonomic status and ecological partitioning of night monkeys genus Aotus in western Colombia, with notes on Aotus zonalis Goldman, 1914

TLDR
The morphological variation, distribution patterns, and taxonomy of night monkeys in the genus Aotus from northwestern Colombia deposited at the Field Museum of Natural History are reviewed and GIS based analyses and Maxent modeling are used to define the geographic extent and ecological limiting factors of the analyzed taxa.

Population densities and geographic distribution of night monkeys (Aotus nancymai and Aotus vociferans) (cebidae: Primates) in Northeastern Peru

TLDR
Population densities of two species of night (or owl) monkeys (Aotus nancymai and Aotus vociferans) were estimated using transect census methods, which confirmed that the two species are nowhere sympatric.

Preliminary Observations on the Mottledface Tamarin (Saguinus inustus) on the Lower Río Caquetá, Colombian Amazonia

TLDR
Preliminary data is presented on some aspects of the ecology of this species on the lower Río Caquetá, Colombian Amazonia and the importance of conducting further research on its ecology in the region is discussed.

THE MAMMALS OF PARACOU, FRENCH GUIANA: A NEOTROPICAL LOWLAND RAINFOREST FAUNA PART 2. NONVOLANT SPECIES

TLDR
Systematic research with nonvolant mammal specimens collected as voucher material resulted in the discovery of new taxa, documented range extensions of previously described species, and helped resolve many longstanding taxonomic problems.

Chromosome evolution in the owl monkey, Aotus

TLDR
The mechanism of chromosomal evolution is reconstructed and the hypothesis that isolated groups of ancestral individuals living in several confined areas have separately accumulated a fusion or inversion pair as a result of inbreeding is proposed.

Genus Cebus Q- and G-band karyotypes and natural hybrids.

TLDR
The comparative study of the Q- and G-band patterns indicates an independent chromosome evolution for C. capucinus and C. albifrons and the statement of two natural hybrids from C. apella derived from a common ancestor more similar to C.Capucinus.

TLDR
The results of attempts to transmit a strain of P. vivax from El Salvador from monkey to monkey by sporozoite inoculation are reported.

Chromosome polymorphism and banding patterns in the owl monkey (Aotus).

Diploid numbers, chromosome morphology, G- and C-banding characterisitics and pelage phenotypes were studied in 330 owl monkeys (Aotus) captured and exported from several parts of South America.

Plasmodium falciparum and Plasmodium vivax infections in the owl monkey (Aotus trivirgatus). I. The courses of untreated infections.

TLDR
The characteristics of infections with these plasmodia in owl monkeys were remarkably similar to those of human infections, and these strains appear to have much to offer in the search for new antimalarial drugs.

Two new chromosome complements of Aotus trivirgatus griseimembra are described making a total of five different karyotypes observed in this subspecies inhabiting Panama and the northwestern part of

XX/"XO" sex determination system in a population of Peruvian owl monkey, Aotus.

TLDR
The chromosome complement of a group of owl monkeys with typical pelagic features characteristic of Aotus inhabiting the upper Amazonian region in South America was analyzed by various band techniques and substantiates the postulation that the owl monkey is an evolutionary actively diverging species.
