Morcegos (Chiroptera) da área urbana de Londrina, Paraná, Brasil

Study carried out within the urban perimeter of Londrina, which is located in the North of the state of Parana. The objectives were the identification of urban species of bats and diurnal roosts used by them and the verification of the problems they can cause to the population. The fire brigade, the Autarquia Municipal do Ambiente de Londrina (Municipal Environment Autarchy of Londrina), the Biology Department of the Universidade Estadual de Londrina (State University of Londrina) and local residents helped spot the roosts. The collections were carried out in regular intervals between April 1998 and March 1999. By the end of them, 815 bats of 23 different species had been captured. Among these, 12 were found near or inside human constructions: Noctilio albiventris Desmarest, 1818; Artibeits lituratus (Olfers, 1818); Platyrrhinus lineatus (E. Geoffroy, 1810); Eptesicus brasiliensis Desmarest 1819; Lasiurus bore-alls (Muller 1776); Lasiurus ega (Gervais, 1856); Eumops glaucinus (Wagner, 1843); Molossus rufus (E. Geoffroy, 1805); Molossus molossus (Pallas, 1766); Nyctinomops laticaudatus (E. Geoffroy, 1805); Nyctinomops macrotis (Gray, 1840) e Tadarida brasiliensis (i. Geoffroy, 1824). Roost sites comprised expansion joints, roofs, attics and parks, among others. It can be concluded that bats are treated as undesirable animals by the population due to the lack of knowledge about the subject.

New Genus and Species of Nectar-Feeding Bat from the Atlantic Forest of Southeastern Brazil (Chiroptera: Phyllostomidae: Glossophaginae)

ABSTRACT The lowland Atlantic Forest of southeastern Brazil is well known for its biological diversity and numerous endemic taxa. Among bats collected recently at the Reserva Natural Vale and previously in the Floresta Nacional de Goytacazes, in the state of Espírito Santo, are specimens easily recognized as nectar-feeding glossophagines, but that exhibit a suite of morphological traits that preclude assignment to any of the 10 genera currently recognized in the subfamily Glossophaginae. Here we describe a new genus and species based on this material. This new taxon, named Dryadonycteris capixaba, is diagnosed based on both external and craniodental features, including traits not seen in other nectar-feeding phyllostomids, such as similar-sized calcar and foot and inflated maxillary bones. The combination of character states seen in Dryadonycteris suggests that it belongs in the Tribe Choeronycterini, subtribe Choeronycterina, but the mosaic nature of primitive and derived states seen in this taxon precludes easy assessment of its relationships to other choeronycterine genera. Future explicit phylogenetic analyses of morphological data and DNA sequencing studies will be necessary to resolve its phylogenetic position within Choeronycterini.
