“…Estimates of the divergence dates reported for this split range from 11 to 8 Ma, considerably older than the radiation of the marmosets that began to diversify about 6−5 Ma (Matauschek et al ., ; Perelman et al ., ; Schneider et al ., ; Buckner et al ., ). Studies have shown that genetic distances are generally greatest when members of the small‐bodied group are compared with those of the large‐bodied groups (Meireles et al ., ; Jacobs Cropp et al ., ; Canavez et al ., ; Araripe et al ., ; da Cunha et al ., ).…”

“…Since the Jacobs, Larson & Cheverud () study of phylogenetic relationships in Saguinus , analyses of molecular, protein and cytogenetic data have consistently revealed a deep divergence between a small‐bodied clade (the nigricollis group) and the remaining larger tamarins (Meireles et al ., ; Canavez et al ., ; Jacobs Cropp et al ., ; Tagliaro et al ., ; Araripe et al ., ; da Cunha et al ., ; Matauschek et al ., ; Perelman et al ., ; Springer et al ., ; Sampaio et al ., ) (Table , Fig. ).…”

“…() who used both mtDNA and nuclear sequences, and da Cunha et al . () who analysed DNA sequences of five nuclear genes with Alu insertions, have indicated however, that it may be a sister to S. mystax , S. labiatus or S. mystax + S. labiatus , and as such is a well‐embedded member of the mystax group.…”

Taxonomic review of the New World tamarins (Primates: Callitrichidae)

Twelve generic names have been ascribed to the New World tamarins but all are currently placed in just one: Saguinus Hoffmannsegg, 1807. Based on geographical distributions, morphology, and pelage patterns and coloration, they have been divided into six species groups: (1) nigricollis, (2) mystax, (3) midas, (4) inustus, (5) bicolor and (6) oedipus. Molecular phylogenetic studies have validated five of these groups; each are distinct clades. Saguinus inustus is embedded in the mystax group. Genetic studies show that tamarins are sister to all other callitrichids, diverging 15À13 Ma. The small-bodied nigricollis group diverged from the remaining, larger tamarins 11À8 Ma, and the mystax group diverged 7À6 Ma; these radiations are older than those of the marmosets (Callithrix, Cebuella, Mico), which began to diversify 6À5 Ma. The oedipus group diverged from the midas and bicolor groups 5À4 Ma. We review recent taxonomic changes and summarize the history of the generic names. Taking into account the Late Miocene divergence time (11À8 Ma) between the large-and smallbodied tamarin lineages, the small size of the nigricollis group species when compared with other tamarins, and the sympatry of the nigricollis group species with the larger mystax group species, we argue that the nigricollis group be recognized as a distinct genus: Leontocebus Wagner, 1839.

“…Although there are many phylogenetic hypotheses for tamarins (Jacobs et al, 1998;Cropp et al, 1999;Tagliaro et al, 2005;Matauschek et al, 2011;Cunha et al, 2011;Buckner et al, 2015;Athaydes et al, 2021;Brcko et al, 2022), the most of last taxonomic decisions, that is, the delimitation of species was not based on those phylogenies and has used the distinguishability criteria to define the taxa. Currently, tamarins comprise 22 species and 20 subspecies (Rylands et al, 2016).…”

Taxonomic status of Tamarinus imperator subgrisescens (Lönnberg, 1940) (Cebidae, Callitrichinae)

The emperor tamarin, Tamarinus imperator, is composed of two subspecies, the nominal type, T. i. imperator, distributed between the Acre and Purus Rivers, whose range is limited between the Brazilian state of Acre and Peru are unbounded, and T. i. subgrisescens, occurring in Peru, Bolivia, and Brazil, in the Brazilian states of Acre and Amazonas. Morphologically, both taxa are easily identifiable by the pelage pattern (chromogenetic fields), and even being easily distinguishable, both lineages are considered subspecies according to the criterion based on the Biological Concept of Species from the 1970s, even without presenting some necessary criteria, such as the intergradation zone. Here we analyzed pelage traits, cranial morphometry, Cytochrome-b divergence, and distributional pattern data applying the premises of integrative taxonomy to elucidate the taxonomic status of both lineages. We hypothesize that both lineages are considered full species through a series of criteria for species recognition, such as distinguishability, level of phenotypical divergences of several morphological complexes with congruence among them, and some genetic divergence. The hybridization is unknown and the low or the lack of sampling in target areas does not allow us to determine whether a hybridization or even contact zone between the two lineages exists indeed. All character sets analyzed were congruent with each other and reinforced the high level of divergences between the two subspecies including several pelage differences, morphometry (descriptive statistics, PCA, and MANOVA), and mitochondrial DNA Cytochrome-b divergence. Most of the distribution in both lineages are allopatric, and the levels of intra-lineage phenotypical variation are much lower than between the lineages.

“…They are classified in two subfamilies ( Alu J and Alu S), based on their age. Given these characteristics, SINEs have been widely used as phylogenetic markers [Kramerov et al, ; Roos et al, ; da Cunha et al, ; Shimamura et al, ; Serdobova and Kramerov, ].…”

Three families of New World monkeys, the Pitheciidae, Atelidae, and Cebidae, are currently recognized. The monophyly of the Cebidae is supported unequivocally by the presence of ten unique Alu elements, which are absent from the other two families. In this paper, the five genomic regions containing these Alu elements were sequenced in specimens representing nine capuchin (Cebus, Sapajus) species in order to identify mutations that may help elucidate the taxonomy and phylogenetic relationships of the cebids. The results confirmed the presence of previously described Alu elements in the capuchins. An Alu insertion present in the Cebidae2 genomic region belonging to the AluSc subfamily was amplified and sequenced only in Sapajus. No amplified or unspecific product was obtained for all other species studied here. An AluSc insertion present in the CeSa1 region was found only in Cebus, Sapajus, and Saimiri. Cebidae4 was characterized by two insertions, an AluSz6 shared by all cebids, and a complete SINE (AluSx3) found only in the capuchins (Cebus and Sapajus). The genomic region Cebidae5 revealed two insertion events, one of the AluSx subfamily, which was shared by all cebids, and another (AluSc8), that was unique to Cebus, offering a straightforward criterion for the differentiation of the two genera, Cebus and Sapajus. The Cebidae6 region showed four distinct insertion events: a 52-bp simple repeat ((TATG) n), two very ancient repeats (MIRc) and a TcMar-Tigger shared by all New World monkeys studied so far, and an Alu insertion of the AluSx subfamily present exclusively in the cebids. The phylogenetic tree confirmed the division of the capuchins into two genera, Cebus and Sapajus, and suggested the southern species Sapajus nigritus robustus and S. cay as the earliest and second earliest offshoots in this genus, respectively. This supports a southern origin for the Sapajus radiation.
