Allegheny Mountain Dusky Salamander vs. Northern Dusky Salamander

Both have the pale line from the eye to the jaw and heavy hind legs, so ignore those. Look at the tail: a Northern Dusky's is flattened on the sides and sharply keeled along the top, wedge-shaped or triangular in cross-section; an Allegheny Mountain Dusky's is rounded or oval at the base and only weakly keeled. Then the back: a Northern Dusky is duller and dark brown, any tan stripe plain and fading with age; an Allegheny Mountain Dusky usually has a brighter, well-defined stripe (yellow, red, orange or brown) edged with dark lines, often with a row of dark V-shaped marks down the middle.
