Pseudis
There are seven species in this genus if we think of Lysapsus as a different genus. Until the late 1990s and early 2000s, most scientists said only P. minuta and P. paradoxa counted as frogs in Pseudis.  Scientists wrote the first paper about P. cardosoi. Before that, scientists thought P. cardosoi was the same frog as P. minuta. All the other species remaining were thought to be subspecies, synonyms or populations of P. paradoxa. Not all scientists agree that P. platensis is not the same frog as P. paradoxa.
