Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Habitat

This species inhabits the canopy layer of pristine cloud forests in Mexico's mountains, specifically requiring moss-covered branches and dense epiphytic vegetation that maintain constant moisture levels. The specialized arboreal microhabitat exists only within a narrow elevational band where persistent cloud cover creates the humid conditions essential for this lungless salamander's survival.
