B. altasierrae can be distinguished from other closely related Batrachoseps species by its relatively low number of maxillary teeth and trunk vertebrae.
Coloration (in preservation): The dorsum and limbs are a dark blackish-brown, with the ventral surfaces a lighter brown. A dark brown to reddish-brown stripe runs down the dorsal surface (Jockusch et al. 2012).
Color in life is overall dark with a dark reddish back set off with a lateral dark brown to black stripe; its sides are flecked with tiny white speckling which continue onto its limbs.
Distribution and Habitat
Country distribution from AmphibiaWeb's database: United States
U.S. state distribution from AmphibiaWeb's database: California
B. altasierrae inhabit coniferous forests, specifically forests containing pine, fir, and incense cedar (Jockusch et al. 2012).
Trends and Threats
Possible reasons for amphibian decline
General habitat alteration and loss
The species epithet altasierrae comes from the name of a hamlet at the summit of the Greenhorn Mountains, Alta Sierra. B. altasierrae is common in that area.
B. altasierrae populations were considered to be B. relictus prior to the description of B. altasierrae in 2012.
B. altasierrae most closely related to B. kawia, which inhabits similar habitats north of the Tule River drainage (Jockusch et al. 2012).
