Northern Two-lined Salamander vs. Southern Two-lined Salamander

Range separates these best: Northern Two-lined in northeastern Ohio, Southern Two-lined in the south and west. Where they meet, look at the tail: the dark side lines break up before halfway on a Northern, and run past halfway, often to the tip, on a Southern. Count the grooves along the side between the legs: 15 or 16 on a Northern, 13 or 14 on a Southern.
