“…In addition, monophyly across the hypothesised range for most species has yet to be explicitly tested. Four new species have been formally described since 2010 (as well as one resurrected taxon; Defler, Bueno, & García, ; Gualda‐Barros, Nascimento, & Amaral, ; Dalponte, Silva, & Silva‐Júnior, ; Vermeer & Tello‐Alvarado, ), and given the many uncertainties/unknowns, further changes to the species‐level taxonomy of each of the callicebine genera are likely. New species descriptions and/or modifications to hypothesised species’ distributions may impact how accurately callicebine taxa are represented in our biogeographic analyses.…”

Titi monkeys, subfamily Callicebinae, are a diverse, species‐rich group of Neotropical primates with an extensive range across South America. Their distribution in space and time makes them an interesting primate model for addressing questions of Neotropical historical biogeography. Our aim was to reconstruct the biogeographic history of Callicebinae to better understand their diversification patterns and the history of their colonisation of South America since the late Miocene. We reconstructed a time‐calibrated phylogeny of 19 titi species under Bayesian inference using two mitochondrial and 11 nuclear loci. Species were assigned across eight Neotropical areas of endemism, and statistical biogeographic methods implemented in BioGeoBEARS were employed to estimate ancestral areas using 12 biogeographic models. Our results indicate that the most recent common ancestor to extant titi monkeys was widespread from the present‐day Andean foothills in the Colombian Amazon, through the wet and dry savannas of Bolivia and Brazil, to the southern Atlantic forest of eastern Brazil. Genus‐level divergences were characterised by vicariance of ancestral range in the late Miocene. Species‐level diversification in Cheracebus and the Plecturocebus moloch group occurred as they spread across the Amazon in the Pleistocene and were largely characterised by a sequential, long‐distance “island‐hopping” dispersal model of speciation from a narrow area of origin through jump dispersal across rivers. This study comprises the first large‐scale investigation of the evolutionary history of titi monkeys in the context of Amazonian and South American historical biogeography and sheds light on the processes that generated the great diversity found among Callicebinae.

“…We included specimens of species assigned to the C. moloch group by van Roosmalen et al's [2002] classification, as well as those falling into van Roosmalen et al's [2002] C. cupreus , and C personatus groups because some of those species were considered part of the moloch group by others authors (e.g., Groves []; Hershkovitz [, ]). We also included samples of individuals from newly described species C. vieirai and C. miltoni [Dalponte et al, ; Gualda‐Barros et al, ]. The sample codes, sources, and localities are shown in Table , and the localities are plotted in Fig.…”

“…van Roosmalen et al [] followed the proposal of Kobayashi [], but raised all subspecies to the species level, based on the phylogenetic species concept. Since then, nine new putative species have been discovered and incorporated into these groups based on morphological, ecological, and biogeographical criteria [Dalponte et al, ; Silva Júnior et al, ; Vermeer & Tello‐Alvarado, ].…”

Callicebus is a Neotropical primate genus of the family Pitheciidae, which currently comprises 34 recognized species. Based on their morphological traits and geographic distribution, these species are currently assigned to five groups: the C. moloch, C. cupreus, C. donacophilus, C. torquatus, and C. personatus groups, although in the past, alternative arrangements have been proposed based on the analysis of morphological data. The principal disagreements among these arrangements are related to the composition of the C. moloch group. In the present study, we tested the different taxonomic proposals for the C. moloch group, based on the molecular analysis of nuclear markers (Alu insertions and flanking regions) and three mitochondrial genes (16S, COI, and Cyt b), with a total of approximately 7 kb of DNA sequence data. Phylogenetic reconstructions based on maximum likelihood and Bayesian inference methods indicated that the species of the current C. cupreus group should be reintegrated into the C. moloch group. In addition, our results corroborated previous studies suggesting that the species of the current C. personatus group form a distinct species group. We also observed a relatively subtle level of divergence between C. dubius and C. caligatus. While the known diversity of Callicebus is considerable, these findings indicate that the relationships among groups and species may still not be completely understood, highlighting the need for further research into the biological, geographic, and genetic variability of these primates, which will be fundamental to the effective conservation of the genus.

Dental microwear texture analysis in mammalian ecology

1. Neoecology and paleoecology both seek to answer the same questions, albeit using different material, at different time scales and with different limitations. Nevertheless, too often, neoecologists neglect paleoecology, and paleoecologists only use neoecology as a baseline for actualism. One reason for this is the lack of tools that can be applied to both fields. 2. This is a review of the contributions to both neoecology and paleoecology of three-dimensional (3D) dental microwear texture analysis (DMTA), a method that can act as a bridge between these fields. 3. DMTA studies can be grouped according to the type of ecological questions researchers seek to answer: specific ecology, intra-specific ecology, niche partitioning and dietary overlap, and ecology over time. The first question has been the main focus of research; the other three were only superficially studied. 4. In this review, selected examples will be presented to demonstrate that DMTA, as one of the few tools that can be applied to both modern and fossil samples, has been used to address key ecological questions in mammalian neoecology and paleoecology. 5. With the wide range of neoecological and paleoecological questions that DMTA can answer, it is clear that this methodology will be used increasingly in the future, possibly in combination with other ecological proxies.
