The southeastern dwarf salamander grows from 2.0 to 3.5 inches in length. It has a slender body and a long tail. It is typically yellow-brown in color with darker brown blotching and dark stripes down each side, but the pattern and coloration can vary widely. The epithet quadridigitata is to denote that each of its feet has four toes.
Bog dwarf salamander (Eurycea sphagnicola), found in southern Mississippi, Alabama, and the far western Florida panhandle Index of animals with the same common name This page is an index of articles on animal species (or higher taxonomic groups) with the same common name ( vernacular name).
It is the most divergent of the eastern species in the dwarf salamander complex, having diverged from the clade containing E. quadridigitata, E. hillisi, and E. chamberlaini during the late Oligocene to mid-Miocene, about 23-15 million years ago. [4]
Chamberlain's dwarf salamander is a very small species, averaging just 2.5 centimetres (1.0 in) in total length. [6] E. chamberlaini is known to be a lighter brown color than E. quadridigitata (which it is commonly confused with) and has a yellowish underbelly with no spots.
It was described in 1947 but later synonymized with the southeastern dwarf salamander (Eurycea quadridigitata). However, a 2017 study used . In addition, genetic studies indicate that it may be more closely related to the radiation of neotenic Eurycea of the Edwards Plateau in Texas than to the rest of the E. quadridigitata complex.

Parvimolge is a genus of salamanders in the family Plethodontidae, the lungless salamanders. [3] It is currently considered as monotypic, although this may yet change as molecular data suggest that it is embedded within a paraphyletic Pseudoeurycea.
It was previously thought to be a population of the southeastern dwarf salamander (E. quadridigitata) but a 2017 study found it to be a distinct species based on genetic evidence, and described it as E. hillisi. It is named in honor of American evolutionary biologist David Hillis. It is unlikely that any previous studies had analyzed ...
