Resumen

Pigmentation disorders, either from the complete absence (albinism), partial (leucism), or excess ( melanism) of melanin, are rare in vertebrates. Worldwide, only a few records of these disorders had been reported for bats. Thanks to recent fieldwork and examination of museum specimens of the collections of the AMNH and MUSM, we report five species with those conditions in Peru. In this study, we report the first cases of leucism in Artibeus anderseni , Chiroderma trinitatum , and Desmodus rotundus and partial melanism in Carollia perspicillata . Additionally, we report the first record of an albino bat ( Molossus molossus ) for Peru.
