Abstract 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… 
A new species of arboreal rat, genus Oecomys (Rodentia, Cricetidae) from Chaco
TLDR
A new species of rodent is added to the highly diverse genus Oecomys based on specimens collected in the Argentinian provinces of Chaco and Formosa, characterized by a derived carotid circulatory pattern.
Integrative analysis supports a new species of the Oecomys catherinae complex (Rodentia, Cricetidae) from Amazonia
TLDR
From molecular analyses, it is recovered that the western lineage of O. catherinae is a monophyletic group with high genetic divergence from the other lineages of the complex, increasing to 19 the number of species within Oecomys.
Distribution of Oecomys catherinae Thomas, 1909 (Rodentia: Cricetidae) in northeastern Brazil with karyotypical and morphometrical notes
TLDR
The presence of O. catherinae in the semi-deciduous forests of the state of Paraiba, representing the northernmost records of the species in the Atlantic forest and thereby extending its known geographical limits is reported.
Genetic and morphological variability in South American rodent Oecomys (Sigmodontinae, Rodentia): evidence for a complex of species
TLDR
The results suggest that O. paricola may be a complex of species that have been separated for some time, and are in the process of morphological and molecular differentiation as a consequence of reproductive isolation at the geographic and chromosomal levels.
Taxonomic status and phylogenetic relationships of Marmosa agilis peruana Tate, 1931 (Didelphimorphia: Didelphidae), with comments on the morphological variation of Gracilinanus from central–western Brazil
TLDR
An emended diagnosis, description and comparisons with congeners for G. peruanus, a marsupials of the family Didelphidae that ranges from central Peru to central Bolivia and western Brazil in the states of Rondonia and northwestern Mato Grosso, where it occurs in sympatry with G. agilis.
Intense genomic reorganization in the genus Oecomys (Rodentia, Sigmodontinae): comparison between DNA barcoding and mapping of repetitive elements in three species of the Brazilian Amazon
TLDR
The data presented in this work reinforce intra- and interspecific variations observed in the diploids number of Oecomys species and indicate that chromosomal rearrangements have led to the appearance of different diploid numbers and karyotypic formulas.
A new species of Cystoisospora Frenkel, 1977 (Apicomplexa: Sarcocystidae) from Oecomys mamorae Thomas (Rodentia: Cricetidae) in the Brazilian Pantanal
TLDR
The results indicate that the prevalence of Cystoisospora mamorae n.
A Systematic Review of Sulawesi Bunomys (Muridae, Murinae) with the Description of Two New Species
TLDR
Two new species of of Bunomys are described, B. karokophilus and B. torajae, both from the west-central mountain region of central Sulawesi, and the morphological, elevational, and ecological relationships among the four species are described.
Morphological and Geographic Definitions of the Sulawesian Shrew Rats Echiothrix leucura and E. centrosa (Muridae, Murinae), and Description of a New Species of Sucking Louse (Phthiraptera: Anoplura)
TLDR
The present report documents morphological and distributional limits of species in Echiothrix, places one of those species in an ecological and parasitological landscape and analyses of morphometric traits derived primarily from cranial and dental measurements document the presence of two species.

A New Species of Oryzomys (Rodentia: Muridae) from Eastern Bolivia
TLDR
The Bolivian sample has the closest genetic relationship to O. perenensis (Kimura 2-parameter genetic distance × 100: 14.8) and O. laticeps, but the genetic distance is large, and it is described as a new species.
Systematic studies of Oryzomyine rodents (Muridae, Sigmodontinae): diagnoses and distributions of species formerly assigned to Oryzomys 'capito'
TLDR
This study considers Fischer’s (1814) Mus megacephalus to be valid and available, designate a neotype to bear the name, and reinstate it as a senior synonym of capito Olfers (1818).

On the Contents of Gracilinanus Gardner and Creighton, 1989, with the Description of a Previously Unrecognized Clade of Small Didelphid Marsupials
TLDR
Separate and combined phylogenetic analyses of nonmolecular data and nuclear gene sequences suggest that Cryptonanus and Gracilinanus are reciprocally monophyletic and closely related, although they were not consistently recovered as sister taxa in any analysis.
THE MAMMALS OF PARACOU, FRENCH GUIANA: A NEOTROPICAL LOWLAND RAINFOREST FAUNA PART 2. NONVOLANT SPECIES
TLDR
Systematic research with nonvolant mammal specimens collected as voucher material resulted in the discovery of new taxa, documented range extensions of previously described species, and helped resolve many longstanding taxonomic problems.
Phylogenetic Relationships of Oryzomine Rodents (Muroidea: Sigmodontinae): Separate and Combined Analyses of Morphological and Molecular Data
TLDR
A phylogenetic hypothesis for the tribe Oryzomyini is provided that can be used to understand the diversification and evolution of this group of rodents and to revise the current generic-level classification.
Phylogenetic Relationships and the Radiation of Sigmodontine Rodents in South America: Evidence from Cytochrome b
TLDR
The overall pattern suggests a rapid radiation of the sigmodontines in South America, followed by differentiation at the tribal and generic levels.
MAMMALS OF THE RIO JURUÁ AND THE EVOLUTIONARY AND ECOLOGICAL DIVERSIFICATION OF AMAZONIA
TLDR
It is shown that, while there are few examples of taxa for which the Rio Juruá is apparently a barrier, most taxa either are largely undifferentiated throughout the basin or are sharply divided into reciprocally monophyletic mtDNA haplotype clades separable into upriver and downriver units.
Mammals of South America
The vast terrain between Panama and Tierra del Fuego contains some of the world's richest mammalian fauna, but until now it has lacked a comprehensive systematic reference to the identification,

TLDR
Two genera, Pionopsitta parrots and Selenidera toucans, corroborate a well known biogeographic disjunction in which taxa endemic to southern Central America and the Chocó region of northwestern South America are the sister‐group to a radiation within the Amazon basin.
