“…This result is similar to that described for this species (Yonenaga et al, 1976). Oligoryzomys nigripes normally presents variation in their number of autosome arms (NA) due to pericentric inversions occurring in pairs 3, 4 and 8, showed in individuals from Bahia, Rio de Janeiro, São Paulo, Minas Gerais, Espírito Santo and Rio Grande do Sul (Almeida and Yonenaga-Yassuda, 1991;Andrades-Miranda et al, 2001;Bonvicino and Weksler, 1998;Paresque et al, 2004;Yonenaga et al, 1976;Zanchin, 1988). The X and Y chromosomes can also be polymorphic (Almeida and Yonenaga-Yassuda, 1991;Andrades-Miranda et al, 2001Paresque et al, 2004).…”

The Chapada Diamantina (CD) is located in Bahia State, between 11-14° S and 41-43° W, being part of the Serra do Espinhaço. The occurrence of different habitats and transition areas permits an interesting mammal fauna composition, with species from different biomes living in sympatry. Species of Didelphimorphia and Rodentia are important members of mammal communities in almost all different habitats, and morphological and cytogenetic characters are important for a correct identification of most of these species. In this work 258 specimens of small mammals from the orders Didelphimorphia (six genera and six species) and Rodentia (two families, five Sigmodontinae tribes, nine genera and 11 species) were collected during the whole field work (44 nights

“…This suggests at least two pericentric inversions to derive one karyotype from another. The 2n = 62 and FN = 64 karyotype has also been attributed to O. eliurus (Svartman, 1989;Andrades-Miranda et al, 2001), but morphological examination and sequencing of some of the karyotyped specimens listed by these authors (MN36928, MN36746) confirm they are O. mattogrossae.…”

“…The anteroconid of the first lower molar (m1) is without an anteromedian flexid; the mesolophid is distinct on unworn m1 and m2; m2 and m3 with anterolabial cingulum. (Myers and Carleton 1981;Svartman 1989;Andrades-Miranda et al, 2001;Pereira and Geise, 2009;Di-Nizo et al, 2015).…”

Species of the cricetid genus Oligoryzomys are found across most Neotropical biomes, and several of them play important roles as natural reservoirs of hantaviruses and arenaviruses. Here we demonstrate that O. mattogrossae, previously considered a junior synonym of O. microtis, is a valid species, and that it is the oldest available name for specimens previously identified as O. fornesi from Brazil and northern Paraguay. Comparative morphology and phylogenetic analyses based on mitochondrial (cytochrome b) and nuclear (intron 7 of beta-fibrinogen) genes show that O. mattogrossae differs from its sister species O. microtis and from other forms of the genus, corroborating previously published karyological data. Oligoryzomys mat togrossae occurs in Cerrado and Caatinga habitats throughout central and northeastern Brazil and Paraguay, whereas distribution of O. fornesi is apparently restricted to southern Paraguay and northernmost Argentina. Specimens of O. mattogrossae were found to be the natural reservoir of the Anajatuba genotype of hantavirus in northeastern Brazil. Therefore, continuing
