Information from diversity inventories was used to study patterns of biodiversity and species distribution, to identify potential priority areas for conservation, and to guide future sampling efforts. In this context, we compiled information on non‐volant small mammal communities from the high Andes (>2,000 m.). Here, we present an open source data...

Tropical South America, in particular Amazonia, has been identified as the area of the basal diversification of several large mammal clades. Whether this scenario also holds for younger and widely distributed clades remains unclear. Here, we assessed the historical biogeography of a young but diverse and widely distributed mammal clade. The Neotrop...

The genus Oligoryzomys is the most speciose genus in the tribe Oryzomyini; however, under the general lineage concept of species, at least nine lineages are pending review and naming. In this study, I carry out qualitative and quantitative morphological analyses of specimens of Oligoryzomys andinus, O. aff. andinus, and O. arenalis, to delimit thes...

Se presenta una lista actualizada de los mamíferos vivientes con registros en Chile, compilada en diciembre de 2020. La lista incluye 163 especies silvestres agrupadas en 85 géneros, 31 familias y ocho órdenes. De estas especies, 20 son endémicas del país. También se provee la lista de 22 especies exóticas con poblaciones silvestres en Chile. Dado...

Recently, Agnolin et al. (2019) described 14 new species of mammals, including 12 rodents, one bat, and one carnivore, and one new subspecies of rodent. In addition, these authors proposed several other nomenclatorial acts: some nominal forms were removed from synonymies and hypothesized as distinct species, at the time that three new genera, one s...

According to the ICZN (1999), the type locality is where the specimen used as holotype, syntype or lectotype was collected (Art. 76). As such, the type locality is a source of information about the habitat and geographical occurrence of a taxon. Topotypes, specimens collected within the type locality of a species or subspecies, have been used in co...

Oligoryzomys, as currently understood is formed by 25 living species, is the most diverse genus of the tribe Oryzomyini of the New World subfamily Sigmodontinae of cricetid rodents. Nonetheless, the species richness of Oligoryzomys seems to be an underestimate, given some species complex has been proposed in previous stud- ies, at the time that lar...

Andean long-tailed mice of the genus Oligoryzomys have a complex and instable taxonomic history. Recent studies, in addition to circumscribe O. destructor to populations from southern Peru up to the north, and O. brendae to those from Argentina and southern Bolivia, have identified a candidate species in northern Bolivia. Herein, we assessed the st...

The Neotropical genus Gardnerycteris has been recently erected and described as a result of a morphologically-based phylogenetic analysis of Phyllostominae with emphasis on representatives of Mimon sensu lato. As currently understood Gardnerycteris is formed by two species, G. crenulatum and G. koepckeae. However, it has been hypothesized that G. c...

The genus Oligoryzomys, distributed from southern South America to southern North America, is the most diverse of the tribe Oryzomyini of sigmodontine rodents. Even when 22 species are currently recognized, species boundaries are unclear for several forms. The species Oligoryzomys destructor is one of the least studied species of the genus and is t...

The large spiny mouse Neacomys spinosus (Thomas, 1882) has been considered the widest ranging species of the genus, occurring in southern Colombia, eastern Peru, western Brazil and northern Bolivia. The morphological variation between subspecies and populations of N. spinosus has been noted; nonetheless, this variation has not been assessed in a mo...

A previous study showed that Dromiciops gliroides has deep phylogeographic structure, with 3 allopatric and highly differentiated groups. Here, we constructed on that study by assessing the morphologic variation of D. gliroides . Our results show that along its distribution Dromiciops is morphologically highly variable and that the geographic patte...

As a strategy to reserve energy for parental care, females are larger than males in most bat species. Although females are responsible for providing parental care in almost all (if not all) bats, there are some species in which the males are larger than the females, and in other species the sexes are similarly sized. It has been proposed that for n...

INTRODUCTION Mimon is currently considered a monophyletic genus that comprises two subgenera: Mimon (represented by M.bennettii and M. cozumelae), and the taxon formerly named "Anthorhina"(represented by M. crenulatum and M. koepckeae). However, recent molecular phylogenies show Mimon as a polyphyletic genus within Phyllostomidae. METHODS Herein,...

Mimon koepckeae Gardner & Patton, 1972 is a poorly-known bat species, with only three known specimens, including the holotype. Its distribution is restricted to the type locality in Ayacucho Department, Peru, and surroundings. This species has been synonymized with M. crenulatum by some authors. Based on a new specimen of M. koepckeae collected fro...

However, recent molecular phylogenies show Mimon as a polyphyletic genus within Phyllostomidae. Methods: Her...

We extent the distribution range in Peru of Asthenes sclateri, Cabanis ("Puna Canastero"), a species reported only for the Puno Department. The observations of many individuals of the species (documented with pictures and specimens) were made in high Andean pastures nearby Polylepis woodlands in the Arequipa Department.
