Description

provided by AmphibiaWeb articles
Moderately long limbs with its small, short body generally accompany the dark colored Batrachoseps relictus . Typical size of B. relictus is normally 3.5-4.7 cm in length. There are usually 16-20 costal grooves with 7-9.5 costal folds between the toes on addressed appendages on this species. A colored dorsal stripe may be present in some individuals, ranging from red to yellow or dark brown. The stripe is often difficult to identify in large individuals.The Kern Canyon Slender Salamander may be distinguished from B. relictus by possessing a relatively larger trunk of 20-21 costal grooves. Light flecks on a dark ventral also are characteristic of the Kern Canyon Slender Salamander. The relatively small fore and hind feet of the Gregarious Slender Salamander distinguish it from B. relictus. This species account was written based on the description in (Stebbins 2003).

Distribution and Habitat

provided by AmphibiaWeb articles
This western species of salamander may be found at higher elevations, associated with areas of pine, cedar, fir, and incense. Deciduous oaks may also sometimes provide a suitable habitat. B. relictus has also been found in the rocky habitat of Lower Kern Canyon in Kern, CO, although it has not been documented in recent years.

Relictual slender salamander

provided by wikipedia EN

The relictual slender salamander (Batrachoseps relictus) is a species of salamander in the family Plethodontidae. It is endemic to California, found only a small area in Kern County, California.[1]

Distribution

This salamander's range is on Breckenridge Mountain located on the western slopes of the southern Sierra Nevada, east of the lower Kern River canyon in Kern County.[1] Much of what was formerly known as the relictual slender salamander has now gone over to the Greenhorn Mountains slender salamander (Batrachoseps altasierrae), the Fairview slender salamander (Batrachoseps bramei) and the Kern Plateau slender salamander (Batrachoseps robustus).

Presently relictual slender salamanders exist at only two sites on Breckenridge Mountain separated by a mere three miles. This locale is south and west of the range of the Kern Canyon slender salamander (Batrachoseps simatus). The species formerly existed to the west in the lower Kern River Canyon (the location of the type locality), but these populations have all gone extinct for unknown reasons. Further down the Kern River Canyon, the Gregarious slender salamander (Batrachoseps gregarius) occurs.

The relictual slender salamander's natural habitats are freshwater springs and riparian areas, interior chaparral and woodlands, and temperate coniferous forests.
