One cryptid which has a realistic chance of existing is South American wolf Dusicyon avus. Officially a Pleistocene megafauna, recent carbon-dating put some specimens as few 100s year old only. And it is likely to be overlooked as either a feral dog or one of native foxes.

There is also a very small chance that Madagascar giant lemurs or dwarf hippos survived, because there are local reports from the 1950s. However, they were publicized in 1995 already, so no follow up during 25 years.
