Phyllobates sp. aff. aurotaenia is a temporary name given to a species of poison dart frog, formerly known as the "red" form of Phyllobates aurotaenia. It is morphologically similar to P. aurotaenia, but genetically it is more closely related to P. terribilis and bicolor. It is the third-most toxic of the poison dart frog species and the third-largest of its genus.
