Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. Have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data.

Five individuals were captured using mist nets in the District of Bugre (25º29'52"S, 49º39'24"W) and four in the District of São Luiz do Purunã (25º28'18"S, 49º42'53"W), both in the Municipality of Balsa Nova, State of Paraná, Southern Brazil. These areas are located within the domain of the Araucaria Pine Forest, in the region of the Devonian Scarp. In addition to the record of two new points of occurrence of this poorly know species in the State of Paraná, this study also reports on data on reproductive biology and use of daily roost by M. bennettii.

The highest richness of bat species is found in the state of Paraná, with 64 species, followed by Santa Catarina with 46, and Rio Grande do Sul, with 40. The family Phyllostomidae plays an important role in determining this pattern. The geographical distributions of Trachops cirrhosus (Spix, 1823), Artibeus cinereus (Gervais, 1851) and Thyroptera tricolor Spix, 1823 are expanded to the state of Paraná, establishing a new southern limit for these species and for Thyropteridae. In addition Myotis dinellii Thomas, 1901 is first recorded in Brazil, in Santa Catarina and Rio Grande do Sul, establishing a new eastern limit for this species. The distribution of Eptesicus taddeii Miranda, Bernardi & Passos, 2006 is extended by a new record in Rio Grande do Sul. An updated list of bats for the southern Brazilian states is presented with few nomenclatural adjustments. The importance of more intensive field efforts to survey the chiropterofauna is highlighted as a way to improve conservation efforts based on representative surveys and scientific collections.

We observed 2 types of behavioral responses: the descent to the understory followed by the dispersion of the group and immobility and silence. Brown howlers displayed behaviors specific to evading aerial predators, which are similar to the ones in other Neotropical primates.

In this study, a list of chiropteran species of the municipality of Frederico Westphalen, in the northernmost region of Rio Grande do Sul, is provided, as well as information on the use of human buildings and abandoned mines for seven of the 25 species recorded in the municipality. From October, 2004 to June, 2008, sampling was carried out in eleven areas of the municipality in order to survey the local chiropterofauna. The presence of species was recorded based on captures using mist nets, active searches in shelters, and specimens obtained from local residents. The recorded species belonged to 13 genera, of which 11 belonged to the family Vespertilionidae, whereas the families Molossidae and Phyllostomidae were represented by seven species each. The results obtained in the present study place the Upper Uruguay among the regions of highest species richness in Rio Grande do Sul.

Howler monkeys, being relatively large animals, were believed to be preyed on successfully only by medium to large-sized carnivores and large birds of prey. Our study took place at Chácara Payquerê, which is situated in the municipality of Balsa Nova, State of Paraná, Southern Brazil. Fingers and nails from Alouatta guariba clamitans Cabrera, 1940 were founded in two faecal samples from Leopardus pardalis (Linnaeus, 1758). With our documentation large howler monkey remains in faeces, the possibility of ocelot being a potential predator of all Neotropical primates should be taken into consideration.

The growth and subsequent fission of the group are described and argued, as well as their possible underlying causes, focusing on the population ecology and social behavior of this taxa.

An example of their current sympatry and the rediscovery of free-ranging potential hybrids of A. caraya and A. clamitans in the forests of the Upper Paraná River, Southern Brazil, are reported in this paper. Eight groups were observed in the study area: five monospecific groups of A. caraya, two of A. clamitans, and a group containing two adult males and two adult females of A. caraya and a sub-adult male and two adult females identified as Alouatta sp. The color of the last three individuals was a mosaic between the two species; this is consistent with previously described variations in museum specimens collected in the Paraná River in the 1940s that had been identified as potential hybrids. The results from this study emphasize the need for scientific studies in the region of the Ilha Grande National Park, one of the few regions in the Paraná River that currently harbors both howler species.

The results of an investigation of diagnostic morphological characters and a multivariate morphometrics analysis suggest the recognition of two forms, E. bonariensis and E. patagonicus Thomas, 1924, thus altering considerably the distributional scenario of these forms in southern Brazil.

Three specimens were collected in Frederico Westphalen (27º2133"S and 53º2340"W) within the domain of the Deciduous Seasonal Forest. Morphometric and taxonomically diagnostic characters are provided for the collected specimens, as well as relevant data to the understanding of the reproductive biology of the species. An ectoparasitic hemipteran is also reported.
