“…Additional study of all material has persuaded us that Emmons' fourth form represents a new species of Oecomys that we document herein. A key diagnostic feature of the new species involves its derived carotid arterial circulatory pattern, a characteristic shared with two other Oecomys species, O, concolor (Wagner, 1845) and O. mamorae (Thomas, 1906b). Based on this potential synapomorphy (e.g., see Weksler, 2006), we critically differentiate the new species in contrast to O, concolor and O. mamorae and concurrently refine the definitions and distributions of the latter two.…”

We describe a new species of Oecomys, O. sydandersoni (Cricetidae: Sigmodontinae), from the Parque Nacional Noel Kempff Mercado in eastern Bolivia. One of its diagnostic traits, a derived carotid circulatory plan, provides morphological evidence for its close relationship to O. concolor and O. mamorae among the 15 species of Oecomys currently recognized. Notwithstanding this shared trait, other morphological contrasts and morphometric analyses demonstrate the sharp differentiation of the eastern Bolivian form from both of those species. Oecomys sydandersoni, n. sp., is arboreal and was encountered above ground on limbs and woody vines only in densely wooded hummocks scattered through grassland, in contrast to adjacent closed tropical deciduous forest where three other species of Oecomys (O. bicolor, O. roberti, O. trinitatis) were obtained. The new species represents the fourth sigmodontine rodent to be named from this restricted region within eastern Bolivia since 1999. Its documentation served as a platform to summarize the nomenclatural history, morphological recognition, and geographic distribution of O. concolor (Wagner, 1845) and O. mamorae (Thomas, 1906) based on fresh examination of all type material and museum specimens. diagnosticas, el plan de circulation carotideo derivado, provee evidencia de su relation cercana con O. concolor y O. mamorae entre las 15 especies de Oecomys reconocidas hasta la fecha. Ademas de esta caracteristica compartida, otras caracteristicas morfologicas y analisis morfometricos demuestran la gran differentiation de la forma del este boliviano de las otras dos especies. Oecomys sydandersoni, n. sp., es una especie arboricola y fue encontrada sobre el nivel del suelo en ramas y lianas, solamente en montecillos boscosos esparcidos por la sabana, a diferencia del bosque adyacente tropical deciduo donde las otras tres especies de Oecomys (O. bicolor, O. roberti, O. trinitatis) fueron encontradas. Esta nueva especie es el cuarto roedor sigmodontino descrito para esta zona del este boliviano desde 1999. Su documentation sirve como una tribuna para compendiar la historia natural, el reconocimiento morfologico, y la distribution geografica de O. concolor (Wagner, 1845) y O. mamorae (Thomas, 1906) basados en la examination del material tipo y de especimenes de museo.

“…While originally described as a true species (Thomas, 1903), flaviceps has been classified in recent years as a subspecies of both Callithrix jacchus © 1995FFI, Oryx, 29 (3), 192-196 (Hershkovitz, 1977 and C. aurita (CoimbraFilho, 1990). The most recent and comprehensive review of Callithrix taxonomy (de Vivo, 1991) nevertheless supports the original classification (see also Mittermeier et al, 1992).…”

We propose the first molecular systematic hypothesis for the origin and evolution of Cebus capucinus based on an analysis of 710 base pairs (bp) of the cytochrome c oxidase subunit II (COII) mitochondrial gene in 121 C. capucinus specimens sampled in the wild. The animals came from the borders of Guatemala and Belize, Costa Rica, and eight different departments of Colombia (Antioquia, Chocó, Sucre, Bolivar, Córdoba, Magdalena, Cauca, and Valle del Cauca). Three different and significant haplotype lineages were found in Colombia living sympatrically in the same departments. They all presented high levels of gene diversity but the third Colombian gene pool was determined likely to be the most ancestral lineage. The second Colombian mitochondrial (mt) haplogroup is likely the source of origin of the unique Central America mt haplogroup that was detected. Our molecular population genetics data do not agree with the existence of two well-defined subspecies in Central America (limitaneus and imitator). This Central America mt haplogroup showed significantly less genetic diversity than the Colombian mt haplogroups. All the C. capucinus analyzed showed evidence of historical population expansions. The temporal splits among these four C. capucinus lineages were related to the completion of the Panamanian land bridge as well as to climatic changes during the Quaternary Period.
