Scincella is a genus of lizards in the skink family, Scincidae, commonly referred to as ground skinks. The exact number of species in the genus is unclear, as taxonomic reclassification is ongoing, and sources vary widely. Scincella species primarily range throughout the temperate regions of the world and are typically small, fossorial lizards, which consume a wide variety of arthropods. They are a generalized insectivore with well developed chemosensory abilities.

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 mountains, 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 172 km (107 mi) 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.
Ptychohyla zophodes is a species of frogs in the family Hylidae. It is endemic to Mexico and known from the Atlantic slopes of the Sierra Madre de Oaxaca in northern Oaxaca and adjacent central-western Veracruz.

The specific name zophodes is a Greek word meaning "dusky" or "gloomy" and refers to the distinctive dark coloration of the species as well as its cloud forest habitat. Common name gloomy mountain stream frog has been coined for it.
