|Taxonomic Notes:||This form might be a complex of more than one species consisting of two taxa from the northern and southern parts of the range (Shaffer 1983, Shaffer and McKnight 1996).|
|Red List Category & Criteria:||Least Concern ver 3.1|

Listed as Least Concern in view of its wide distribution and its presumed large population.
|Previously published Red List assessments:|
|Range Description:||This species occurs in the Sierra Madre Occidental from northeastern Sonora to the south in western Chihuahua, east Sinaloa to Durango and Zacatecas, and south to Jalisco, Mexico, at 1,675-3,100 m asl.|
Native:Mexico (Chihuahua, Durango, Jalisco, Nayarit, Sinaloa, Sonora, Zacatecas)

|Population:||This species is common throughout its range.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||This species occurs only at high elevations in pine and pine-oak forest with slow-flowing, shallow streams. It occurs in both streams (its presumed natural habitat) and artificial ponds for livestock (in which it can reach very high larval densities). The species is variable with respect to metamorphosis; it can breed as a metamorph or as a paedomorph. The adults live in farmland, ranch land, and forest.|
|Use and Trade:||There are no records of this species being utilized.|
|Major Threat(s):||Introduced predatory fishes are a problem and expansion of agriculture might pose a threat to this species. However the species does fine in areas with cattle grazing, at least as long as breeding habitat is available. In Nayarit's Sierra Madre Occidental, tourism has recently increased, with tourists going to the mountain arroyos where the salamanders live, which may affect the species in the future. This may lead to a deterioration in water quality and increased litter pollution (V.H. Luja pers. comm. Red List Assessment workshop June 2014). Overall, this species is probably not seriously threatened.|
It occurs in a few protected areas but improved habitat protection is needed throughout its range and is protected under the category Pr (Special protection) by the Government of Mexico.
Environmental education with local (indigenous) people is urgent (V. H. Luja pers. comm. Red List Assessment workshop June 2014).
Further research into the taxonomy is necessary to determine a possible form complex between populations.
