| Cerradomys is a Neotropical genus of cricetid rodents with seven recognized species, Cerradomys subflavus, C. maracajuensis, C. marinhus, C. scotti, C. langguthi, C. vivoi, and C. goytaca. Species of the genus are distributed throughout the open vegetation belt across South America, from northeastern and southeastern Atlantic coast of Brazil to eastern Paraguay and Western Bolivia. Here we describe a new species of Cerradomys from the state of Tocantins in Central Brazil, based on morphological, karyological and mitochondrial DNA analyses. This species is characterized by a medium body size and long tail, dense dorsal pelage, overall dorsal color gray olive lined with yellow, color of head and dorsum continuous, ventral body color slightly yellowish, skull... |

| La especificidad es uno de los principales atributos de los parásitos. El hallazgo de especies parásitas altamente específicas puede brindar información sobre los hospedadores. Además, la especificidad hospedatoria describe patrones de asociación actual que pueden reflejar la historia macroevolutiva. En este trabajo se analizó la especificidad hospedatoria de los nematodes Syphaciini (Oxyuridae) parásitos de roedores Muroidea (Rodentia) americanos y en particular de roedores akodontinos de Argentina. Por otra parte, con el fin de distinguir posibles eventos evolutivos, los conocimientos taxonómicos, ecológicos y los resultados de especificidad de los nematodes Syphaciini se integraron con la filogenia de los roedores Akodontini. Los resultados mostraron... |

| We report the first record of occurrence of Loxodontomys pikumche Spotorno et al., 1998, in the Central Andes of Argentina. We briefly describe external characters, skull, karyotype, and habitat; also, we provide general comparisons with the other known species in the genus, L. micropus. |

| Species of small mammals from southwestern Buenos Aires province range within a wide variety of habitats, herbaceous (Pampean District), shrubs (Monte District), steppes, and xerophytic woodlands (Espinal District). Their natural history is still poorly known. In this paper we make a synthesis of the taxonomy and distribution of the marsupials (Marmosinae) and rodents (Sigmodontinae) of southwestern Buenos Aires province. Distributional records and taxonomical information were obtained from field survey, analyses of raptor pellets, revision of specimens housed in collections in Argentina, and literature. Between Sierra de la Ventana (38º S) and the río Negro (41ºS) occur two species of marmosines and 14 of sigmodontine rodents. Some of these species show a... |
