Description:
Small species. More terrestrial than the other Desmognatus salamanders. The upper body has a broad, straight-edged vertebral stripe that varies in color from yellow, red, orange to shades of brown and is bordered on each side by dark brown to black stripe that becomes lighter and mottled towards the belly. A medial row of dark chevron-shaped markings occur within the middle of the stripe, but they may be absent. The stripe extends from the back of the head though the body and onto the tail. The underside is light grey to greyish-black and immaculate or may be lightly mottled that becomes darkens with age. Older individuals are often melanistic or uniform dark brown to black.
