This species occurs in extreme central-eastern Sonora and western Chihuahua along the Sierra Madre Occidental, south to western Durango and extreme north-eastern Sinaloa, Mexico.
Habitat and Ecology
It inhabits pristine conifer forests where it can be commonly found along low rivers and streams, where it breeds. It is not present in altered habitats.
This is a rare species.
Disturbance, and any kind of alteration of forested areas that might cause the desiccation of streams and soils, are threats to this species.
This species occurs in at least two protected areas. Urgent protection of the forested areas along the Sierra Tarahumara area is recommended.
Red List Status
Near Threatened (NT)
Listed as Near Threatened since the species depends on streams in pristine forest, and so its Area of Occupancy is probably not much greater than 2,000 km2, and the extent and quality of its habitat in the Sierra Madre Occidental in Mexico is declining, thus making the species close to qualifying for Vulnerable.
