“…On the contrary, as several sigmodontine rodents (see Patton et al, 2000;Bonvicino, 2003;D'Elía and Pardiñ as, 2004;Gonçalves et al, 2005;Emmons and Patton, 2005;Percequillo et al, 2005) these species are diagnosed by a unique combination of character states, together with karyologic, morphometric, and molecular evidence.…”

Cerradomys is a monophyletic genus that includes four known species, Cerradomys subflavus, C. maracajuensis, C. marinhus, and C. scotti, distributed throughout the open vegetation belt across South America, from northeastern Brazil to southeastern Bolivia, and from eastern to northwestern Paraguay. We revised the status of the species currently assigned to this genus by analyzing skins, skulls, karyotypes, and cytochrome b DNA sequences. We also described two novel species, one distributed in the Brazilian states of Minas Gerais, Bahia, and Sergipe, and the other in the states of Paraíba,

“…These include the forest oryzomyine Hylaeamys acritus (Emmons and Patton, 2005), the akodonts Juscelinomys huanchacae and /. guaporensis (Emmons, 1999), and the rare marsupial Cryptonanus unduaviensis (Voss et al, 2005), which has been collected in the grassland matrix that surrounds the woodland patches inhabited by O. sydandersoni (Emmons et al, 2006). Whether the restricted ranges apparent for this group of species reflect a common historical response to the interplay of ecological change and biogeographic events in eastern Bolivia invites further research (Emmons et al, 2006).…”

“…As its distribution is so far known, O. sydandersoni joins other species with limited geographic ranges that have been recently documented from extreme eastern Bolivia, in the Parque Nacional Noel Kempff Mercado or its vicin- ity. These include the forest oryzomyine Hylaeamys acritus (Emmons and Patton, 2005), the akodonts Juscelinomys huanchacae and /. guaporensis (Emmons, 1999), and the rare marsupial Cryptonanus unduaviensis (Voss et al, 2005), which has been collected in the grassland matrix that surrounds the woodland patches inhabited by O. sydandersoni (Emmons et al, 2006).…”

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.
