Description

This species is a small, somewhat slender yellowish salamander with moderately webbed digits and a dark midventral longitudinal stripe. Adults are 83 to 91 mm in total length. Adult males are 38 mm in standard length, while adult females are 37 to 42 mm in standard length. Tail is long, about 55 to 58% of its total length. Eyes are moderately large and protuberant. Adults have 31 to 58 maxillary teeth and 18 to 22 vomerine teeth. There are 3 to 3 1/2 costal folds between adpressed limbs. Hands and feet are relatively broad and are only somewhat webbed, with all digits somewhat free of webbing and the two phalanges on the longest digits completely free of webbing. Subterminal pads are present on all digits except the first one. Head width is 14 to 16% of standard length, and leg length is 22 to 25% of standard length (Savage 2002).

Juvenile dorsal ground color ranges from bright yellow to a golden tan. Dorsal patterning consists of irregular, scattered black to brown streaks and spots. Ventral color is silver to cream with a reddish brown midventral stripe. Iris is gold (Savage 2002).
