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.

Voiceless Treefrog (Plectrohyla siopela)
The Voiceless Treefrog was described in 1968, it was restricted to the western slope of the Cofre de Perote Mountain in the Sierra Madre Oriental in central Veracruz, Mexico, where the frogs inhabited dry pine forests spending the days hidden in crevices and under rocks behind small cascades of mountain streams.
The species reached a length of 4 to 5 cm, with the females being slightly larger than the males
The Voiceless Treefrog was once abundant but has not been seen since around 2010 and is now feared to have gone extinct.

Rabb’s Fringe-limbed Treefrog (Ecnomiohyla rabborum)
Rabb’s Fringe-limbed Treefrog, described in 2008, was only ever known from a single locality in Panama.
The species reached sizes of up to 10 cm.
***
The wild population of this species collapsed shortly after its discovery in 2005 due to chytridiomycosis, which killed countless amphibian populations across Central America.
The species was considered functionally extinct since the 2010s because at that time there was apparently only one single specimen left, a male that was kept in the Botanical Garden of the city of Atlanta in Georgia, USA.
This last known member of its species (see photo), however, died today, September 26, 2016, thus this species is now indeed fully extinct.
