“…Particularly noteworthy is Mico argentatus, a species of the newly recognized genus, which shows the same chromosomal syntenies with respect to Cebuella pygmaea ), but has a large amount of heterochromatin at the terminal ends of two chromosomes; the C. jacchus karyotype differs from that of other species by a single fission. In particular, a comparison of classical cytogenetic data on tamarins, Saguinus and Leontopithecus, shows that they have similar karyotypes (2n = 46) and differ only by para-and pericentric inversions detected on at least four acrocentric chromosomes (data not shown in Figure 2) (Nagamachi et al 1997b;Neusser et al 2001). …”

Platyrrhini are a group of Neotropical primates living in central and south America, and have been extensively studied through morphological and molecular data in order to shed light on their phylogeny and evolution. Agreement on the main clades of Neotropical primates has been reached using different approaches, but many phylogenetic nodes remain under discussion. Contrasting hypotheses have been proposed, presumably due to different markers and the presence of polymorphisms in the features considered; furthermore, neither Neotropical primate biodiversity nor their taxonomy are entirely known. In our perspective, a cytogenetic approach can help by making an important contribution to the evaluation of the phylogenetic relationships among Platyrrhini. In this work, molecular cytogenetic data regarding the principal nodes of the Neotropical monkey tree have been reviewed; classical cytogenetic data have also been considered, especially when other data have proven elusive, permitting us to discuss highly derived karyotypes characterized by a wide range of diploid numbers of chromosomes and variable chromosomal evolution with different rearrangement and polymorphism rates.

“…The species were karyotyped by 4′,6-diamidino-2-phenylindole (DAPI) inverted banding: after DAPI staining of metaphases chromosomes, pictures were analysed through the software Adobe Photoshop to get the inverted DAPI staining. The karyotypes matched published Giemsa Banding data for S. geoffroyi [ 7 ], S. oedipus [ 7 , 13 ], S. mystax, Leontocebus fuscicollis [ 9 , 11 , 12 ] and Leontopithecus rosalia [ 12 , 13 ]. Chromosomes were classified according to the nomenclature proposed by Levan et al [ 33 ].…”

“…The species of the genus Saguinus have rather similar G-banded karyotypes with differences in heterochromatin distribution, as revealed by a C-banding comparison. Indeed, many species of the genera Saguinus , Leontopithecus and Leontocebus fuscicollis share the same diploid number 2n = 46 but differ mainly by the C-banding pattern [ 6 , 7 , 8 , 9 , 10 , 11 , 12 ]; for example, Saguinus midas and Leontopithecus rosalia have similar chromosome morphologies, but they differ through a paracentric inversion and four pericentric inversions, as well as through the distribution and quantity of heterochromatin [ 11 , 12 ].…”

“…Comparative chromosomal painting between representative species of Saguinus and Leontopithecus did not reveal interchromosomal rearrangements [ 13 , 14 , 15 ], but intrachromosomal rearrangements have been hypothesised through cross-species comparison of conventional G-banding [ 11 , 12 ] and mapping of BACs (Bacterial Artificial Chromosomes) by FISH [ 16 , 17 ]. A large portion of the genome in Primates consists of repetitive DNA sequences, including tandem and dispersed satellite repeats [ 18 ].…”

“…The variation in number and topology of rDNA loci has been shown at the inter- and also at the intra-species level, most commonly explained as a consequence of chromosomal rearrangements, transposition events or ectopic recombination through association of rDNA loci with other chromosomal segments occurred during meiotic division [ 22 , 27 , 28 ]. The topology of rDNA loci has been identified in a few species of the genus Saguinus by classical and molecular methods [ 7 , 11 , 12 , 21 , 29 ], in Leontopithecus rosalia through silver staining [ 11 ] and in Leontopithecus chrysomelas by rDNA-FISH [ 14 ].…”

Tamarins are a distinct group of small sized New World monkeys with complex phylogenetic relationships and poorly studied cytogenetic traits. In this study, we applied molecular cytogenetic analyses by fluorescence in situ hybridization with probes specific for telomeric sequences and ribosomal DNA loci after DAPI/CMA3 staining on metaphases from five tamarin species, namely Leontocebus fuscicollis, Leontopithecus rosalia, Saguinus geoffroyi, Saguinus mystax and Saguinus oedipus, with the aim to investigate the distribution of repetitive sequences and their possible role in genome evolution. Our analyses revealed that all five examined species show similar karyotypes, 2n = 46, which differ mainly in the morphology of chromosome pairs 16–17 and 19–22, due to the diverse distribution of rDNA loci, the amplification of telomeric-like sequences, the presence of heterochromatic blocks and/or putative chromosomal rearrangements, such as inversions. The differences in cytogenetic traits between species of tamarins are discussed in a comparative phylogenetic framework, and in addition to data from previous studies, we underline synapomorphies and apomorphisms that appeared during the diversification of this group of New World monkeys.

Cytogenetic and cytotaxonomic studies (G, C, sequential G/C, and NOR banding) were performed on 110 specimens representing the four genera of South American primates of the family Callitrichidae: Cebuella (C. pygmaea), Callithrix, groups argentata (C. argentata, C. emiliae, C. chrysoleuca, C. humeralifera, C. mauesi), and jacchus (C. aurita, C. geoffroyi, C. jacchus, C. kuhli, C. penicillata), Leontopithecus (L. chrysomelas, L. rosalia), and Saguinus (S. midas midas, S. m. niger). Mitotic chromosomes are characterized, and the rearrangements distinguishing the karyotypes of the taxa are inferred from arm homologies. The results were then converted into numerical data and submitted to cladistic analysis. The following conclusions were achieved: 1) Five karyotypic classes were observed, which correspond to the five taxa studied. Differences between them are as follows: a) Cebuella (2n = 44, 10 acrocentrics, A + 32 bi‐armed autosomes, bi) and the argentata group (2n = 44, 10A + 32bi) are different from each other due to a reciprocal translocation; b) both can be distinguished from the jacchus group (2n = 46, 14A + 30bi) by a centric fusion/fission rearrangement and a paracentric inversion; c) Leontopithecus (2n = 46, 14A + 30bi) and Saguinus (2n = 46, 14A + 30bi) differ from the jacchus group by a reciprocal translocation and three paracentric inversions; and d) Saguinus is different from the others by one paracentric inversion and pericentric inversions in at least four pairs of acrocentric autosomes. 2) The cladistic analysis separates Cebus (used as an outgroup) from the Callitrichidae groups, which forms a clade. Among the Callitrichidae, marmosets (Cebuella and Callithrix) form a sub‐clade, Cebuella and the argentata group being more closely related to each other than both are to the jacchus group. Tamarins (Leontopithecus and Saguinus) are also quite close, so that if one was not derived from the other, they with the marmosets share a common ancestor. Among the tamarins, Leontopithecus is karyotypically closest to the marmosets, specifically to the jacchus group. 3) Based on the chromosome information and considering the possible direction of the evolutionary changes (primitivity or phyletic dwarfism hypothesis, previously advanced by other authors), it was possible to propose the ancestral karyotypes and to develop two alternatives for the origin, differentiation and dispersion of the callitrichid. Both proposals are plausible, but when the geographical distribution is considered, the phyletic dwarfism hypothesis seems to be the most probable. Am. J.
