The genus was removed from the synonymy of Bufo in 2006; an alternative view has been to treat it as a subgenus of Bufo.[1] At present, it is widely recognized as a genus.[1][3][2][4]
Andinophryne, consisting of three species, was recognized as a separate genus until 2015 when it was found out that its recognition rendered Rhaebo paraphyletic.[1][4] An alternative to synonymizing it with Rhaebo would have been to erect a new genus for Rhaebo nasicus, but this would have caused difficulty in assigning species without molecular data to correct genus.[4]
Rhaebo are characterized as lacking cephalic crests, having omosternum, distinctively wide sphenethmoid, prominent and notched exoccipital condyles, and yellowish-orange skin secretions. It is not clear which of these characters are ancestral and which are derived (i.e., synapomorphies).[4]
