This species is evolutionarily most closely related to the Eurycea. It appears to be rare, and is likely to be of conservation concern. Males are patterned dorsally and have proportionately large nasal cirri. Females are unicolored and either lack or have vestigial nasal cirri. Known only from Stephens County, GA. With a total length of only ~5 cm (~2 inches), an adult Urspelerpes could coil comfortably on a quarter. While other miniaturized salamanders often have 4 toes/foot, Urspelerpes has 5.
