[4] 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.
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.

A 2017 study reaffirmed it as being a distinct species. [4] It is estimated that E. chamberlaini diverged from E. quadridigitata anywhere from 27 to 15 million years ago. [4] Chamberlain's Dwarf Salamander. The species is named for Edward Burnham Chamberlain, a former curator of the Vertebrate Zoology department at the Charleston Museum. [4]
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.

[4] [5] Parvimolge townsendi is endemic to the northern Sierra Madre de Oaxaca in central and southern Veracruz, Mexico, between 900 and 1900 meters elevation. [ 1 ] [ 3 ] It is represented by the species Parvimolge townsendi , commonly known as Townsend's dwarf salamander .
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 ...
