We report the first record of Thyroptera devivoi from Colombia in a palm swamp of Mauritia flexuosa in an aeolian seasonally flooded savanna ecosystem. This record is the seventh specimen and the fifth locality known for T. devivoi and extends the known distribution of the species 1250 km northwest from nearest locality in Guyana. We revised the specimen that was previously reported as voucher material of Thyroptera lavali from Colombia, but it matches in all characters with Thyroptera tricolor. We considered the presence of T. lavali in Colombia uncertain.
