The scientific name of the Golden Toad is Bufo Incilius periglenes. That means that it belongs to the genus Bufo, and the subgenus Incilius (A genus is the smallest group above species, and a subgenus is a division of a genus). Therefor, its closest living relative would be a member of the genus Bufo, and the subgenus Incilius. There are 32 surviving members of the subgenus Incilius, therefor any one of these could be the closest living relative of the Golden Toad.
