Its common name is Tandayapa Andes toad, after its type locality, Tandayapa, in the Pichincha Province);[2] the species has not been seen there after 1970, despite search efforts.[3][4] It is only known from another locality in the Imbabura Province of Ecuador (Manduriacu River).[2][3][5] It has also been reported from one locality on the Colombian Massif, Nariño Department, Colombia, but these have been shown to represent Rhaebo colomai.[4]
