Chamberlain's Dwarf Salamander vs. Coastal Plain Dwarf Salamander

The two dwarf salamanders were long thought colour forms of one species; in North Carolina they mostly keep apart, the Coastal Plain Dwarf in the far south (NC Parks). A: Narrow brown or black side lines; the back light bronze in the Chamberlain's Dwarf Salamander; wide blackish side lines; the back dark brown in the Coastal Plain Dwarf Salamander. B: Pale tail sides, contrasting sharply with the side lines in the Chamberlain's Dwarf Salamander; dark tail sides, not contrasting with the side lines in the Coastal Plain Dwarf Salamander. Turn it over: Chamberlain's belly is bright yellow and unmarked, the Coastal Plain Dwarf's silvery grey. Both have four toes on each hind foot (two-lined salamanders have five).
