Brown-streaked Salamander
Pseudoeurycea mixcoatl
Overview
Pseudoeurycea mixcoatl, commonly known as brown-streaked salamander, is a species of salamander in the family Plethodontidae. It is endemic to Mexico. It is native to the Sierra Madre del Sur of Guerrero state, around the towns of Asoleadero and Carrizal de Bravo. It occurs at elevations ranging between 2,200 and 2,600 meters elevation. Its current known extent of occurrence (EOO) is 50 km2.
Pseudoeurycea mixcoatl faces severe threats from habitat destruction due to agricultural expansion and urban development in its restricted montane range. The species' extremely limited distribution makes it particularly vulnerable to local environmental changes, while deforestation for cattle grazing and crop cultivation continues to fragment its cloud forest habitat. Climate change poses an additional threat by altering the moisture regimes essential for this salamander's survival.
Habitat
This salamander inhabits cloud forests and pine-oak forests in montane regions of central Mexico, typically found under logs, rocks, and leaf litter in moist microhabitats. It requires cool, humid conditions with consistent moisture levels characteristic of high-elevation forest ecosystems.
