TL;DR: This work found 74 species of bats within 42 genera and seven families already reported in Mato Grosso do Sul, and found Phyllostomidae and Molossidae were the richest families.
Abstract: Bats have been increasingly studied in the last 15 years in Mato Grosso do Sul, and several records were not yet considered in reviews of South American bat distributions. Here, we present the bat species and their distributions in Mato Grosso do Sul based mainly on data compilation from literature, but also on complementary information from zoological collections, and our and colleagues' unpublished records. We found 74 species of bats within 42 genera and seven families already reported in Mato Grosso do Sul. Bat species in this state represent 44% of the Brazilian's bat species (E 169) and 7% of the world's bat richness (E 1120). Phyllostomidae (42) and Molossidae (17) were the richest families. Four species formerly cited for Mato Grosso do Sul are not supported by our compilation, and other 15 species recorded in the vicinity are listed as potential occurrences in this state. We additionally found controversial traits for specimens of Platyrrhinus helleri, and report Eumops dabbenei for the first time in Brazil. Most species were recorded in the regions of Cerrado (60) or Pantanal (57) in Mato Grosso do Sul, but only 16 in the Atlantic Forest. Records of Phyllostomidae species were mostly found in Cerrado and those of Molossidae, in Pantanal. Records in Mato Grosso do Sul determine edges of distribution for at least 22 species of South American bats. The overall known chiropteran fauna of Mato Grosso do Sul is highly diverse and new findings are expected through additional surveys.
TL;DR: The southern limit for the known distribution of the species is extended to extend the southern limit of Eumops dabbenei because of the presence of cartilages in the finger joints.
Abstract: First report of Eumops dabbenei (Chiroptera: Molossidae) for the prov- ince of Entre Rios, Argentina. This is the first report of Eumops dabbenei (Chiroptera: Molossidae) for the province of Entre Rios, Argentina. The specimen was found next to an individual of Eumops bonairensis on the floor of an inhabited building, surrounded by lands for agriculture. The specimen was aged as a young or subadult female because of the presence of cartilages in the finger joints. The external characters agree with the descrip- tion of the species, nevertheless some corporal and cranial measures have smaller values. This report permits to extend the southern limit for the known distribution of the species. Palabras clave. Extension distribucional. Molosido. Nuevo registro.
TL;DR: New records of Eumops dabbenei from Argentina: Distribution ex- tension and comments about its ecology are reported and additional data about reproduction, diet, composition of the colony and roost characteristics were obtained.
Abstract: New records of Eumops dabbenei (Chiroptera: Molossidae) from Argentina: Distribution ex- tension and comments about its ecology. We report two new records of Eumops dabbenei for Argentina. The first record corresponds to a misidentified specimen (originally E. perotis) deposited at the Museo Argentino de Ciencias Naturales, collected in Unquillo (Cordoba province), and represents the first record for this province. The second record, from Copo National Park, Santiago del Estero province, was observed in its roost tree where additional data about reproduction, diet, composition of the colony and roost characteristics were obtained.
