The spotted dusky salamander (Desmognathus conanti) is a species of salamander in the family Plethodontidae. It is endemic to the United States.[2][3][1]
Taxonomy
Desmognathus conanti was described in 1958 by Douglas A. Rossman, but was later reclassified as a subspecies of the northern dusky salamander (D. fuscus).[4] However, numerous genetic and morphological studies since then have affirmed it as being a distinct species.[2][5] In addition, genetic studies indicate that D. conanti is paraphyletic with respect to the Santeetlah dusky salamander (D. santeelah), which lies nested within it; thus, D. conanti itself likely represents a species complex of multiple undescribed cryptic species.[6]
Distribution
Desmognathus conanti has a wide range in the southeastern and south-central United States, ranging from southern Illinois south to the panhandle of Florida, and west to Louisiana and southern Arkansas.[2]
Description

Desmognathus conanti is a moderately stout salamander with a moderately keeled tail. It has several pairs of golden spots on the dorsum that may sometimes fuse to form a light dorsal stripe in adults. The belly is light with dark flecks. It closely resembles D. fuscus and D. santeetlah, and is thus best distinguished from them by range.[4][7][8]
