“…The Paraguayan vouchers we identified here as M. midastactus (MVZ 144481–144484) were previously identified as M. simus by Myers and Wetzel (1979) and Myers and Wetzel (1983), and part of them (MVZ 144483, 144484) were reidentified as M. ruber by Baud and Menu (1993). These vouchers extend the geographic distribution of M. midastactus in ca.…”

BackgroundMyotis midastactus Moratelli and Wilson, 2014 (Vespertilionidae, Myotinae) was described from the Myotis simus Thomas, 1901 complex based on collections from the Bolivian Savannah.New informationFour vouchers previously assigned to M. simus from the Alto Chaco in Paraguay (West of the Paraguay River) are reassigned here to M. midastactus. These specimens extend the geographic distribution of M. midastactus 1200 km southward, and constitute the first evidence of the species in the country. Based on other material from the Brazilian Pantanal and Cerrado, Central Paraguay and north-eastern Argentina, we also discuss the identity of simus-like populations south of the Amazon Basin. The status of these populations is still unclear, but the little evidence we have at hand indicates that these populations may represent another taxon—M. guaycuru Proença, 1943; whereas M. simus seems to be restricted to the Amazon basin. This hypothesis is still very speculative and requires further investigation. With the assignment of material from Alto Chaco to M. midastactus, seven species of Myotis are confirmed for Paraguay: M. albescens, M. lavali, M. levis, M. midastactus, M. nigricans, M. riparius, and M. ruber.

Roosting Ecology of Amazonian Bats: Evidence for Guild Structure in Hyperdiverse Mammalian Communities

The ecological mechanisms that sustain high species richness in Neotropical bat communities have attracted research attention for several decades. Although many ecologists have studied the feeding behavior and diets of Neotropical bats on the assumption that food is a limiting resource, other resource axes that might be important for species coexistence are often ignored. Diurnal refugia, in particular, are a crucial resource for bats, many of which exhibit conspicuous morphological or behavioral adaptations to the roost environment. Here we report and analyze information about roost occupancy based on >500 field observations of Amazonian bats. Statistical analyses of these data suggest the existence of distinct groups of species roosting (1) in foliage, (2) exposed on the trunks of standing trees, (3) in cavities in standing trees, (4) in or under fallen trees, (5) beneath undercut earth banks, and (6) in arboreal insect nests; additionally, we recognize other groups that roost (7) in animal burrows, and (8) in rocks or caves. Roosting-guild membership is hypothesized to have a filtering effect on Amazonian bat community composition because some types of roosts are absent or uncommon in certain habitats. Among other applications of our results, cross-classifying bat species by trophic and roosting guilds suggests that the often-reported deficit of gleaning animalivores in secondary vegetation by comparison with primary forest might reflect habitat differences in roost availability rather than food resources. In general, ecological and evolutionary studies of Neotropical bats would be enhanced by considering both trophic-and roosting-guild membership in future analyses, but additional fieldwork will be required to determine the roosting behavior of many data-deficient species.

“…At this point just over half of the Paraguayan Cingulata fauna had been recorded in the country, but it was not until much later with the first explorations deep into the Chaco region that the true diversity of the country became apparent. Myers & Wetzel (1979) added three armadillo species from the Dry Chaco (Chaetophractus villosus, C. vellerosus, and Ca lyptophractus retusus), and the diligent taxonomic work of Wetzel (1980) finally clarified species limits in the genus Cabassous with the description of a new species, Ca. chacoensis, from a Paraguayan type locality.…”

Distribution and status of Paraguayan Xenarthra: towards a better understanding

Despite great xenarthran biodiversity, the Paraguayan armadillos and anteaters have received little attention from biologists and few data have been published about the distribution and status of the species. Furthermore, errors and contradictions persist in the literature. This paper collates specimen and literature data about this group to act as a basis for the stimulation of future research. Xenarthran specimens in all the major Paraguayan collections and all significant specimens in international collections were examined. Specimen data were collated and supplemented with literature and photographic data. Distribution data are provided according to a hierarchy of record reliability including examined specimens, non-examined specimens, literature records, photographic records, and significant observations. Thirteen species (11 armadillos and two anteaters) are confirmed to be present in Paraguay. Relevant discussion and distribution maps are provided for each species. Specimens of both Dasypus septemcinctus septemcinc tus and D. s. hybridus were examined and their distribution is clarified. There is no evidence that Bradypus variegatus occurs in Paraguay. Most xenarthran specimens were collected at least 35 years ago, and the specimen record may no longer represent current distribution given the rapidly changing landscape in the country. It is concluded that available data on Paraguayan Xenarthra shows a heavy bias taxonomically towards a few species (Dasypus novemcinctus, Tolypeutes matacus, and Euphractus sexcinctus) and geographically towards the Chaco region. Distribution in the Oriental region is poorly understood, and species that are confined to that region are known from few specimens. The southern portion of the Oriental region has been virtually unsampled.
