Sarcohyla cembra, also known as the Southern Sierra Madre treefrog, is a species of frog in the family Hylidae. It is endemic to Mexico. Until recently, it was only known from two male specimens: one from its type locality on the Pacific slopes of the Sierra Madre del Sur, Pochutla District, Oaxaca, and another one from Sierra de Yucuyacua south-east of Llano de Guadalupe, in north-west Oaxaca. The two locations are about apart. After having not been seen after 1993, it was feared that the species might be extinct. However, the species was rediscovered in field surveys in 2011-2012, extending its range with a new locality about 10 km north of the type locality.
