About Aneides iecanus
Shasta Black Salamander (Aneides iecanus)
The Shasta black salamander, scientifically known as Aneides iecanus, is a species of salamander belonging to the family Plethodontidae. This species is endemic to Shasta County in California, with its known distribution primarily centered around Shasta Lake in the western part of the county. There is also potential for its range to extend into the southernmost portions of Siskiyou and Tehama counties.
Description and Taxonomy
First described by Edward Drinker Cope in 1883, the Shasta black salamander was for a time considered synonymous with the speckled black salamander (A. flavipunctatus). However, a significant taxonomic re-evaluation in 2019 re-established Aneides iecanus as a distinct species. Physically, it is characterized as a large salamander with a predominantly black coloration, further distinguished by the presence of white spots. Its body, head, and tail are heavily speckled, which helps differentiate it from other closely related species within the A. flavipunctatus complex. On average, it also possesses one fewer trunk vertebra compared to A. klamathensis or A. niger.
Conservation Status and Threats
The Shasta black salamander is currently classified as Endangered on the IUCN Red List. This status is primarily attributed to its highly restricted geographic range. A substantial portion of its natural habitat was lost during the construction of Shasta Lake. Furthermore, ongoing proposals to raise the Shasta Dam pose a significant threat to the remaining habitat, potentially causing severe damage and further imperiling the species' survival.

Related Salamander and Newt species
Ambystoma lermaense
The Lake Lerma salamander (Ambystoma lermaense) is an extremely rare mole salamander species native to the Toluca Valley in central Mexico. This species is characterized by its neotenic tendencies and has faced a catastrophic decline due to habitat destruction, pollution, and dam construction in its native Lerma River and Lake Lerma wetlands.
Aneides niger
The Santa Cruz black salamander (Aneides niger) is a species of salamander found exclusively in the San Francisco Peninsula of California. It is distinguished from other members of its complex by its predominantly black coloration in adulthood, a trait that develops as it matures from a spotted juvenile. This species faces significant threats due to its limited range, which has been impacted by development, water diversions, and wildfires.
Ambystoma altamirani
The mountain stream salamander (Ambystoma altamirani) is a species of mole salamander native to central Mexico. It is distinguished by its purplish-black dorsal coloration, purplish-lavender belly, and cream-colored accents on its lips, digit tips, and tail fin. This species inhabits high-elevation pine and pine-oak woodlands, breeding in small streams where both larvae and some adults reside, while other adults venture onto land.
