SSAR 9th Edition Comments:
In reference to divergent populations of this species, Devitt et al. (2019, Proceedings of the National Academy of Sciences 116: 2624–2633) states "we recognize three species, two of them new." These species remain undescribed. (Pyron, R. Alexander, Christopher K. Beachy, David A. Beamer, and Kenneth M. Kozak. 2025. Caudata – Salamanders. Pages 10-21 in Kirsten E.

Province/State Distribution:
United States: Texas

Taxonomic Etymology:
Named for its cave-dwelling lifestyle.
Eurycea — Rafinesque (1822) intentionally used a mythological-sounding name, but its specific Greek meaning or derivation was not disclosed. So, while modern etymologists may connect Eurycea to Eurydice or Greek roots (eurys “broad”), Rafinesque himself treated it as a classical name without a defined origin.
troglodytes — Greek trōglē = “hole” + dytes = “diver”; “Cave-dweller”
