Piebaldism is characterized by the absence of melanin in certain areas of the body due the lack of melanocytes as a result of genetic mutations, and which occurs only locally. This study reports the first record of piebaldism for Eptesicus taddeii, a species of bat, endemic to the Atlantic Forest in the South Region of Brazil.

Here, we present an updated list of bats from Guarapuava highlands, center-southern of Paraná state, southern Brazil. This species list is based on four literature records (secondary data) and data from fieldwork (primary data) in three localities. All species recorded (primary and secondary data) were evaluated by the relative frequency and their conservation status were assessed. The species recorded from fieldwork were also evaluated by relative abundance. A beta diversity analysis was done to verify dissimilarities in the bat fauna among the seven localities. We recorded 28 species in the Guarapuava highlands (14 Vespertilionidae, 10 Phyllostomidae and 4 Molossidae), of which, eight are new records for the region. Sturnira lilium was the most abundant in three localities (primary data), and the most frequent species in all studies (primary and secondary data). Only four species were classified globally as "Near Threatened" or "Data Deficient", nevertheless they were frequent in this region. The mean regional beta diversity was 0.72, what could be mostly explained by turnover (0.64) rather than by nestedness (0.08). The greatest species richness of the family Vespertilionidae is a common pattern in subtropical and temperate regions as in highlands and mountains. As turnover was the main component of the beta diversity, the communities seemed to be structured mainly by replacement of species among the studied localities. The Guarapuava highlands present a diverse bat fauna, however, this region requires more sampling effort to become well known.

Não existem barreiras morfofisiológicas para o desenvolvimento das glândulas mamárias em machos, porém, o fato de não amamentarem sua prole é intrigante e tem levantado inúmeras questões há muito tempo. Relatamos o primeiro registro de lactação de machos na espécie de Sturnira lilium para um indivíduo capturado na Mata Atlântica brasileira. O indivíduo apresentou as mesmas características morfológicas externas encontradas em fêmeas lactantes. Não podemos concluir que a amamentação masculina seja uma característica comum da espécie. O efeito de fitoestrógenos e pesticidas necessita de investigações mais profundas sobre as populações de morcegos, bem como sobre o comportamento social de S. lilium.
