Campo Grande Treefrog (Boana cymbalum)
The Campo Grande Treefrog is known from only six specimens that were found in the early 1960s at two sites in São Paulo, Brazil.
The only known localities of this species are now destroyed and despite dozens of targeted surveys, the species has never been recorded since 1963 and thus is officially considered to be extinct.

Phrynomedusa fimbriata Miranda-Ribeiro
Spiny-knee Leaf Frog (Phrynomedusa fimbriata)
The Spiny-knee Leaf Frog was described in 1923, it is known exclusively from the type specimen, a female that apparently was collected in 1898 somewhere in the Paranapiacaba District in the state of São Paulo, Brazil.
This single specimen reaches a size of 4,6 cm and is now in very bad condition with completely faded colors, it is said to have been pale blue dorsally and reddish yellow on the ventral side. [1]

Two additional species within this genus are also known exclusively from their type series, thus, the Spiny-knee Leaf Frog might in fact not be the only extinct species in this genus. [1]
