“…Since chromosomal rearrangements are considered an important factor for speciation in Callicebus [Schneider et al, 1993;Rodrigues et al, 2001Rodrigues et al, , 2004Dumas et al, 2005], we assume that these samples represent distinct species, and designate them herein as CPA-1 [Stanyon et al, 2000;Dumas et al, 2005] and CPA-2 [Barros et al, 2003]. We further suggest that CPA-2 could be a representative of the moloch group, due to the high degree of Gbanding similarity with C. hoffmannsi [Rodrigues et al, 2000].…”

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.

“…cupreus families were housed at the California Regional Primate Research Center at the University of California, Davis, according to standard laboratory protocol, as described in Hoffman, Mendoza, Hennessy, and Mason (1995). C. cupreus was previously considered synonymous with Callicebus moloch (Hershkovitz, 1963) but was recognized as a separate species by Hershkovitz (1990), Schneider et al (1993), Kobayashi (1995), and Groves (1993Groves ( , 2001. Previous research (e.g., Hoffman et al, 1995;Mendoza & Mason, 1986) using the animals from this colony has identified these titi monkeys as C. moloch on the basis of the taxonomy that existed at the time that the colony was established from wild stock.…”

The authors explored whether prolactin is associated with paternal care in 3 monkey species: titi monkey (Callicebus cupreus), common marmoset (Callithrix jacchus), and Goeldi's monkey (Callimico goeldii). They compared prolactin levels in fathers before and after infant birth as well as between fathers and nonfathers. C. cupreus fathers carry infants almost exclusively, have higher prolactin levels than nonfathers, but show no prolactin increase after infant birth. C. goeldii fathers carry infants only after 3 weeks, show an increase in prolactin levels during the precarrying period, but do not have higher levels than nonfathers. C jacchus fathers are the primary carriers, have higher prolactin levels than nonfathers, and show a trend for a prolactin increase after the birth of infants. In conclusion, species differences in the patterns of prolactin secretion were evident and reflect the different paternal roles.

“…An interesting contrast arises from studies investigating divergence between biochemical and cytogenetic di¡erences in the Callicebus moloch group (C. moloch, C. brunneus, C. cupreus) showing the presence of low values of genetic distance (Schneider et al 1993). These authors also suggest that recent karyological rearrangements are possibly the major evolutionary mechanism at the origin of the speciation process in this group of Primates.…”

Mapping genomic rearrangements in titi monkeys by chromosome flow sorting and multidirectional in-situ hybridization

We developed chromosome painting probes for Callicebus pallescens from flow-sorted chromosomes and used multidirectional chromosome painting to investigate the genomic rearrangements in C. cupreus and C. pallescens. Multidirectional painting provides information about chromosomal homologies at the subchromosomal level and rearrangement break points, allowing chromosomes to be used as cladistic markers. Chromosome paints of C. pallescens were hybridized to human metaphases and 43 signals were detected. Then, both human and C. pallescens probes were hybridized to the chromosomes of another titi monkey, C. cupreus. The human chromosome paints detected 45 segments in the haploid karyotype of C. cupreus. We found that all the syntenic associations proposed for the ancestral platyrrhine karyotype are present in C. cupreus and in C. pallescens. The rearrangements differentiating C. pallescens from C. cupreus re one inversion, one fission and three fusions (two tandem and one Robertsonian)that occurred on the C. cupreus lineage. Our results support the hypothesis that karyological evolution in titi monkeys has resulted in reduction in diploid number and that species with higher diploid numbers (with less derived, more ancestral karyotypes)are localized in the centre of the geographic range of the genera, while more derived species appear to occupy the periphery.
