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.
