Southern red-backed salamander

The southern red-backed salamander (Plethodon serratus) is a species of salamander endemic to the United States.[2] It is found in four widely disjunct populations: one in central Louisiana; one in the Ouachita Mountains of Arkansas and Oklahoma; one in central Missouri; and one from southeastern Tennessee, to southwestern North Carolina, western Georgia, and eastern Alabama. It is sometimes referred to as the Georgia red-backed salamander or the Ouachita red-backed salamander. It was once considered a subspecies of the red-backed salamander, Plethodon cinereus.
