Subspecies
Theliderma cylindrica cylindrica
Theliderma cylindrica strigillata
Two subspecies have been described. It is unclear whether they represent distinct evolutionary lineages, or are merely ecophenotypic variation which would not warrant any taxonomic status. A 2007 genetic study has cast doubt upon the validity of the existence of two subspecies.
- Theliderma cylindrica cylindrica (Say, 1817) —
- Theliderma cylindrica strigillata (Wright, 1898) — Rough rabbitsfoot, found only in the headwaters of the Tennessee River.
