Abstract With more than 20 recognized species, Monodelphis is the most species-rich genus of living Didelphidae. Recent research on these opossums revealed additional species from Perú and Venezuela, and herein we describe a new species from the montane forests of the eastern slope of the central Andes in Perú. Monodelphis gardneri, new species, is a small taxon with three black dorsal stripes, more similar in external appearance and cranial features to taxa from eastern Brazil, such as M… 

The second known specimen of Monodelphis unistriata (Wagner) (Mammalia: Didelphimorphia), with redescription of the species and phylogenetic analysis.

TLDR
A detailed redescription of M. unistriata is provided, the first published images of specimens, and the first account, beyond the previous few most vague and incomplete remarks, of the morphology of the skull of the opossum.

A Revised Subgeneric Classification of Short-Tailed Opossums (Didelphidae: Monodelphis)

ABSTRACT Members of the didelphid marsupial genus Monodelphis have previously been classified into species groups, but such informal subdivisions are inconsistent among authors and have contributed

Morphological, morphometric and genetic variation among cryptic and sympatric species of southeastern South American three-striped opossums (Monodelphis: Mammalia: Didelphidae).

TLDR
This study confirmed the sympatry of these two species in a location in southeastern Brazil, presented morphological diagnostic characters to distinguish the two species, provided novel phylogenetic information on the group, and demonstrated the existence of important intra- and interspecific morphological variations related to sexual dimorphism and ontogeny in the group.

Phylogeny and evolution of body mass in didelphid marsupials (Marsupialia: Didelphimorphia: Didelphidae)

TLDR
A fully resolved, highly robust phylogeny of didelphids is recovered that tested and confirmed most previously reported groupings, providing a simultaneous depiction of phylogenetic relationships for 81 % of currently recognized species and all relevant supra-specific clades.

Cambios recientes a la lista de los mamíferos de Colombia

Due to the progress in the development of research of various kinds involving mammals, changes in the richness of species registered in the national territory are reported every year. A notable

How much evidence is enough evidence for a new species?

TLDR
It is argued that there is no real scientific reason for evidence requirements to be stricter due to animal size or popularity, and the evidence presented was sufficient to propose a new species of Tapirus.

NEW SPECIES OF MONODELPHIS (DIDELPHIMORPHIA: DIDELPHIDAE) FROM PERU, WITH NOTES ON M. ADUSTA (THOMAS, 1897)

TLDR
A new species of short-tailed opossum from the lowland forests of Loreto, northeastern Peru is described, intermediate in size and coloration between M. ronaldi and M. adusta, and a phylogenetic analysis of mitochondrial DNA sequences indicates M. osgoodi as its sister taxon.

A new genus and species of rodent from the Brazilian Atlantic Forest (Rodentia: Cricetidae: Sigmodontinae: Oryzomyini), with comments on oryzomyine biogeography

TLDR
A new genus and species of cricetid rodent from the Atlantic Forest of Brazil, one of the most endangered eco-regions of the world, is described, which displays some but not all synapomorphies of the tribe Oryzomyini.

A MOLECULAR PERSPECTIVE ON THE DIVERSIFICATION OF SHORT-TAILED OPOSSUMS (Monodelphis: DIDELPHIDAE)

TLDR
Congruent patterns offer a starting point for developing a sound taxonomy for Monodelphis and more robust hypotheses in regard to its diversification over many diverse Neotropical habitats.

Una nueva especie del género Monodelphis (Didelphimorphia: Didelphidae) de la Sierra de Lema, Venezuela

TLDR
This new species of marsupial is described, based on a specimen collected in the Sierra de Lema (Bolivar State, Venezuela), at the northern border of the Guiana Shield, an area dominated by ombrophilous, evergreen, montane forests.

A remarkable new mouse (Muridae: Sigmodontinae) from southeastern Peru : with comments on the affinities of Rhagomys rufescens (Thomas, 1886) / Lucía Luna, Bruce D. Patterson.

TLDR
A diagnosis and description of the new mouse is provided and its relationships to Rhagomys rufescens are assessed on the basis of morphology; ongoing studies will shed more light on its phylogenetic relationships using morphological and genetic data in a complete phylogenetic analysis.

First record of Rhagomys (Mammalia: Sigmodontinae) in Bolivia

TLDR
A new genus and species of mammal is reported for the fauna of Bolivia, rendering sections of Anderson’s book Mammals of Bolivia obsolete in less than a decade after its publication.

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 and Classification of Didelphid Marsupials, an Extant Radiation of New World Metatherian Mammals

TLDR
A decade of morphological and molecular research on the phylogenetic relationships of didelphid marsupials (opossums) is summarized, with a completely resolved ingroup phylogeny with high support statistics at most nodes.

PHYLOGENETIC STUDIES ON DIDELPHID MARSUPIALS II. NONMOLECULAR DATA AND NEW IRBP SEQUENCES: SEPARATE AND COMBINED ANALYSES OF DIDELPHINE RELATIONSHIPS WITH DENSER TAXON SAMPLING

TLDR
A combined (simultaneous) maximum-parsimony analysis of both datasets (nonmolecular + IRBP) produced a consensus topology that closely resembled the results of analyzing IRBP separately, and a new genus is described for “Marmosa” canescens.
