A new species of Cerradomys (Mammalia: Rodentia: Cricetidae) from Central Brazil, with remarks on the taxonomy of the genus Rev. Bras. Zool.
Bonvicino,Cibele R.; Casado,Flávia; Weksler,Marcelo.
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...

Key to the genera of the Tribe Oryzomyini (Rodentia: Cricetidae: Sigmodontinae) Mastozool. neotrop.
Weksler,Marcelo; Percequillo,Alexandre R..
Due to recent phylogenetic and revisionary taxonomic work, the systematics of the Tribe Oryzomyini, the largest group of sigmodontine rodents, underwent profound changes. We present here an artificial key for the genera of this group of rodents, enabling researchers to identify oryzomyines using external, cranial and dental characteristics. We also present the most up-to-date diversity assessment of the tribe, in which we recognize 33 extant and extinct genera (plus three undescribed genus-group taxa) and 130 valid species.
