“…Some G‐banded metaphases were photographed and afterward submitted to: 1) C‐banding procedure (G/C sequential banding) to the correct pairing of C‐banded karyotype and 2) Ag‐NOR staining (G/NOR sequential banding) to determine what chromosomes pairs are nucleolar organisers. The karyotype was arranged following the previously reported model for C. nigrifrons (N agamachi et al 2003).…”

“…The first and unique report with a representative of personatus group was published by our team. We studied C. nigrifrons and found a karyotype with 2n=42 chromosomes (N agamachi et al 2003). It is a karyotype exclusive for the personatus group and support the hypothesis of personatus as a distinct clade.…”

The genus Callicebus has 28 species arranged in five groups: donacophilus, torquatus, moloch, cupreus and personatus. The personatus group occurs in the Brazilian Atlantic forests where it is isolated from the other Callicebus groups. The present paper is the first report on the karyotype of Callicebuspersonatus. We compared the karyotypes of C. personatus and C. nigrifrons utilizing the following classic banding techniques: G-, C-, NOR banding, G/C- and G/NOR sequential banding. The karyotype of C. personatus has 2n=44, while C. nigrifrons presented 2n=42. Both the species diverge in the diploid number in consequence of a rearrangement type centric fusion/fission. Our results support personatus as a valid group and the specific status for C. personatus and C. nigrifrons.

“…Their diploid numbers range from 16 chromosomes in C. lugens [Bonvicino et al, 2003] to 50 chromosomes in C. donacophilus , C. pallescens , and C. hoffmannsi [De Boer, 1974;Minezawa and Borda, 1984;Stanyon et al, 2000;Rodrigues et al, 2001]. Classical cytogenetic methods, such as G-banding, C-banding and NOR silver-nitrate staining, have been used to examine the chromosomal rearrangements involved in the karyotypic divergence of Callicebus [for review see Minezawa and Borda, 1984;Pieczarka and Nagamachi, 1988;Minezawa et al, 1989;Barros et al, 2000;Rodrigues et al, 2001Rodrigues et al, , 2004Rodrigues et al, , 2006Bonvicino et al, 2003;Nagamachi et al, 2003].…”

Callicebus is a complex genus of neotropical primates thought to include 29 or more species. Currently, the genus is divided into 5 species groups: donacophilus, cupreus, moloch, torquatus and personatus. However, the phylogenetic relationships among the species are still poorly understood. This genus is karyotypically diverse and shows extensive variation in diploid number (2n = 16 to 50). To foster a better understanding of the chromosomal diversities and phylogenetic relationships among the species of Callicebus, we performed a chromosome-painting analysis on the Callicebus personatus genome using human probes, and compared the resulting hybridization map to those of previously mapped titi species. We detected 38 hybridization signals per haploid autosomal set of C. personatus. Few ancestral syntenies were conserved without rearrangement, but 4 human associations (HSA20/13, 3c/8b, 1b/1c and 21/3a/15a/14) were demonstrated to be apomorphic traits for C. persona tus. G-banding suggested that these associations are shared with C. nigrifrons and C. coimbrai (personatus group), while C. personatus is linked with C. pallescens (donacophilus group) by 2 synapomorphies: HSA10b/11 (submetacentric) and an inversion of HSA1a.
