Comprehensive DescriptionRead full entry
This is a small (to about 45 mm snout-vent length; 110 mm total length), slender species with a relatively broad head but only a weakly developed neck. Tails are long and slender, usually much longer than the head + body. Limbs are moderately long for a member of this genus, but from 7 to 8.5 costal folds are uncovered when the limbs are appresed to the trunk. There are 18-19 costal grooves in males and 19-20 in females. As is typical for members of this genus, the digits are small, but well formed, and there are only four digits on the hind limbs. These are blackish animals that have a lighter, brownish, dorsal band that varies from tan to light brown and is streaked or flecked with darkerpigment. The ventral surfaces are pale gray, and there are abundant tiny white spots on the lateral and ventrolateral surfaces, extending onto the venter.
Until recently this species was confused with the widespread congener Batrachoseps attenuatus, which it closely resembles in morphology (this species generally has a wider head and longer limbs).
