Silva Barbosa Leal, Edsonde Figueiredo Ramalho, Daniel2021-08-202021-08-202021-052618-4788http://doi.org/10.31687/saremNMS.21.3.1https://bdc.icmbio.gov.br/handle/cecav/1210Chromatic alterations, including albinism, are rare in wild animals. In bats, at least 160 cases of albinism have been recorded in individuals from ten families. For Mormoopidae, a single case of albinism and two cases of piebaldism are known in the world. This paper documents the rst case of albinism in Mormoopidae in South America, which represents the rst record of pigmentation alteration in Wagner’s mustached bat, Pteronotus personatus (Wagner, 1843) throughout its range. We provide a discussion on the impacts of interaction in roosts on tness and survival of albino individuals.enbat cavePteronotusBrazilCaatingaChromatic disorderTexto publicado em revista
