The taxonomy of muriquis, the largest extant primates in the New World, is controversial. While some specialists argue for a monotypic genus (Brachyteles arachnoides), others favor a two‐species classification, splitting northern muriquis (Brachyteles hypoxanthus) from southern muriquis (B. arachnoides). This uncertainty affects how we study the differences between these highly endangered and charismatic primates, as well as the design of more effective conservation programs. To address this…

Taxonomy of the genus Brachyteles Spix, 1823 and its phylogenetic position within the subfamily Atelinae Gray, 1825
The morphologic phylogenetic analysis shows that Brachyteles is more closely related to Lagothrix than to Ateles, suggesting that the postcranial similarities between muriquis and spider monkeys could be a plesiomorphic condition in Atelidae, and the arboreal quadrupedalism of Alouatta andlagothrix evolved convergently in alouattines and atelines.
Genetic structure in two northern muriqui populations (Brachyteles hypoxanthus, Primates, Atelidae) as inferred from fecal DNA
The genetic diversity of two northern muriqui populations were genetically structured with a high fixation index and seem to indicate that the populations are distinct management units, possibly due to historical subdivision.
Genetic Diversity and Population History of a Critically Endangered Primate, the Northern Muriqui (Brachyteles hypoxanthus)
It is suggested that three populations occurring in protected reserves and one fragmented population inhabiting private lands harbor 22 out of 23 haplotypes, most of which are population-exclusive, and therefore represent patchy repositories of the species' genetic diversity and be treated as discrete units for conservation management purposes.

Re remnant muriqui populations are important genetic reservoirs of alleles that are unique or rare in the species gene pool as a whole and emphasize the need for the integration of conservation management efforts throughout the species range.
Distribution, population size and conservation of the endemic muriquis (Brachyteles spp.) of the Brazilian Atlantic Forest
If conservation actions could be targeted to mitigate the main threat of hunting there is potential for the recovery of muriquis in the state of Rio de Janeiro, at least in the short-term.
Chronology of Deep Nodes in the Neotropical Primate Phylogeny: Insights from Mitochondrial Genomes
This study evaluated the primate timescale focused on the age of nodes of NP radiation and investigated the performance of complete primate mitochondrial genomes as traditional molecular markers of primate evolution, including original mitochondrial data from the endangered muriqui, Brachyteles arachnoides.

Phylogenetic Relationships of Spider Monkeys (Ateles) Based on Mitochondrial DNA Variation
Results of this investigation suggest patterns of gene flow, evolutionary relationships, and speciation patterns that are more plausible than previous pelage-based taxonomies, which required seemingly impossible patterns of Gene flow.
A Current Perspective on the Historical Geographic Distribution of the Endangered Muriquis (Brachyteles spp.): Implications for Conservation
An environmental suitability model for the two endangered species of muriqui (Brachyteles hypoxanthus and B. arachnoides) is developed using Maxent software and it is evident that rivers are potential dispersal barriers for the muriquis.
