First record of Histiotus diaphanopterus Feijó, Rocha & Althoff, 2015 (Chiroptera, Vespertilionidae) in the state of Tocantins, Brazil

We report the first record of Histiotus diaphanopterus Feijó, Rocha & Althoff, 2015 in the state of Tocantins, Brazil and the third record of the species in the Cerrado biome, reinforcing its association with seasonally dry environments of the South American diagonal of open formations. Morphological traits confirm specimen identity, with transparent wings as the most distinctive diagnostic character. Our findings highlight the species’ ecological specificity and exposure to anthropogenic threats, including habitat loss and climate change, underscoring the need for further studies and integrated conservation strategies.
