A small, terrestrial salamander. Adults are 40-50 mm snout to vent length (70-115 mm total length) (Brodie 1970; Petranka 1998). A dorsal stripe with even edges extends to the tip of the tail. Coloration of the stripe ranges from yellow or red to olive green or tan. The red variant is most common. The sides are gray to black, and the venter is gray with white speckling (Leonard et al. 1993; Petranka 1998). Females tend to be larger than males. Hatchlings are 13-15 mm snout to vent length, and juvenile coloration is brighter than adults (Peacock and Nussbaum 1973; Leonard et al. 1993).
