Description
 
Size
Adults are 1 1/4 - 1 7/8 inches long (3.2 - 4.7 cm) from snout to vent.

Appearance
A small slim salamander, with 18-20 costal grooves.
Short limbs, a narrow head, long slender body, very long tail, and conspicuous costal and caudal grooves give this species the worm-like appearance typical of most Slender Salamanders.
There are four toes on the front and hind feet, which is also typical of Slender Salamanders.
(Other California salamanders have five toes on the hind feet.)
Color and Pattern
Dark brown or black above with a brownish or rusty dorsal stripe which is usually absent or not apparent.
Whitish speckling is extensive, especially on the sides.
Venter is gray and lighter than the sides.

Comparison With Sympatric Slender Salamanders
Occurs in sympatry with B. gregarius.
Sympatry with B. relictus is possible.

Life History and Behavior
A member of family Plethodontidae, the Plethodontid or Lungless Salamanders.

Plethodontid salamanders do not breathe through lungs. They conduct respiration through their skin and their mouth tissues, which requires them to live in damp environments on land and to move about on the ground only during times of high humidity. (Plethodontid salamanders native to California do not inhabit streams or bodies of water but they are capable of surviving for some time if they fall into water.)

Plethodontid salamanders are also distinguished by their naso-labial grooves, which are vertical slits between the nostrils and upper lip that are lined with glands associated with chemoreception.

All Plethodontid Salamanders native to California lay eggs in moist places on land.
The young develop in the egg and hatch directly into a tiny terrestrial salamander with the same body form as an adult.
(They do not hatch in the water and begin their lives as tiny swimming larvae breathing through gills like some other types of salamanders.)
Activity
Most Batrachoseps are active on rainy or wet nights when temperatures are moderate, fall through spring, retreating underground when the soil dries or when air temperature drops to near freezing.
At low elevation locations, this species has been found under surface cover from November to April.
At higher elevations, with more severe winter freezes, activity may be restricted to late spring through early fall.
Found under rocks, logs, bark, and other debris.
Defense
Slender salamanders use several defense tactics, including:
- Coiling and remaining still, relying on cryptic coloring to avoid detection.
- Uncoiling quickly and springing away repeatedly bouncing over the ground, then remaining still again to avoid detection.
- Detaching the tail, which wriggles on the ground to distract a predator from the salamander long enough for it to escape. 
(After its tail is detached or severed, the salamander will grow a new tail.)
Diet and Feeding
Probably eats a variety of invertebrates.
Feeding behavior is not known, but other Batrachoseps species are sit-and-wait predators that use a projectile tongue to catch prey.
Breeding
Reproduction is terrestrial.
LIttle is known about the breeding behavior of this species.
Eggs
Other Batrachoseps species lay eggs in moist places on land.
Young
Young develop completely in the egg and hatch fully formed.

Habitat
Inhabits diverse habitats, including mixed deciduous woodlands, mossy talus, and mixed coniferous forest.

Geographical Range
Endemic to the western slopes of the Sierra Nevada Mountains in California.
Found only in the Kaweah river drainage in Tulare county.
Known from only a few localities, the distribution of this species is probably more extensive.
Elevational Range
From 1,410 - 7,200 ft. (430 - 2,200 m.)

Notes on Taxonomy
Prior to its description in 1998, B. kawia was identified as B. relictus.
B. relictus was partitioned into four species -
B. diabolicus
, B. regius, B. kawia and B. relictus.

Here's a Diagram of the Batrachoseps Complex showing the relationships between species.

Conservation Issues  (Conservation Status)
Listed as imperiled by NatureServe, the reason why is not clear. There appears to have been little change in historical and current population numbers at the few known localities, most of which are on public lands.

Meaning of the Scientific Name
Batrachoseps: Greek - amphibian, frog lizard - describes lizard-like appearance.
kawia: derived from the name of the Native Americans who inhabited the region of the type locality.

Conservation Status

The following status listings are copied from the 2017 Special Animals List and the 2017 Endangered and Threatened Animals List which are published by the California Department of Fish and Wildlife.

If no status is listed here, the animal is not included on either CDFW list. This most likely indicates that there are no serious conservation concerns for the animal. To find out more about an animal's status, you can go to the NatureServe and IUCN websites to check their rankings.

Check here to see the most current complete lists.



Organization
Status Listing
NatureServe Global Ranking G1G2 Critically Imperiled - Imperiled
NatureServe State Ranking S2

Imperiled in the state because of rarity due to very restricted range, very few populations (often 20 or fewer), steep declines, or other factors making it very vulnerable to extirpation from the state.
