Pseudoeurycea amuzga, which has been given the common name of Sierra de Malinaltepec salamander, is a species of salamander in the family Plethodontidae. It is endemic to Mexico and known only from Sierra de Malinaltepec, a part of Sierra Madre del Sur in the state of Guerrero.
Its natural habitats are mixed montane forests at elevations of 1645m–1740mm (5,397feet–5,710feetm) above sea level. It has been found under rocks, in holes, and under the bark of trees. It is threatened by habitat loss caused by small-scale farming and wood extraction.
