The dwarf black-bellied salamander (Desmognathus folkertsi) is a species of salamander in the family Plethodontidae. It is endemic to the United States. Its natural habitats are temperate forests and rivers. The dwarf black-bellied salamander (Desmognathus folkertsi) was originally thought to be the blackbelly salamander (Desmognathus quadramaculatus) as they appear similar and are sympatric in the areas that the dwarf black-bellied salamander is found. They can be distinguished through genetically different loci or morphologically in that D. folkertsi are smaller, have different coloration and patterns, and different proportions in body.
