Abstract
This study reports five new records of anomalies in three species of widely distributed bats of the family Vespertilionidae. In Eptesicus taddeii, two individuals exhibited piebaldism, one at the wing tips while another on the dorsal region of the neck. In Eptesicus brasiliensis we observed a mandibular anomaly where the angular process was positioned horizontally at a 45-degree angle. In Myotis nigricans, one individual presented a shortened tail, while another was missing half the proximal phalanx and a distal phalanx. Documenting these unusual traits enhances our understanding of their prevalence and variability in natural populations.
