Reviewed by Martof, 1972, Cat. Am. Amph. Rept., 118: 1–2. See species account by Petranka, 1998, Salamand. U.S. Canada: 480–484. Liu, Moler, Whidden, and Miyamoto, 2004, Copeia, 2004: 136–144, reported on geographic variation in allozyme frequencies and reported syntopy of Pseudobranchus axanthus and Pseudobranchus striatus. Liu, Moler, and Miyamoto, 2006, Mol. Phylogenet. Evol., 39: 149–159, reported on phylogenetics and phylogeography. The data therein suggest that nominal Pseudobranchus striatus is composed of 3-5 lineages which form a paraphyletic series with respect to a group composed of at least 2 lineages of nominal Pseudobranchus axanthus. Given that this elements are geographically coherent, it appears reasonable to assume that multiple species are involved (DRF). Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 43–45, provided photos, maps, and brief accounts of the species. Raffaëlli, 2022, Salamanders & Newts of the World: 12–15, provided accounts of the species, summarizing systematics, life history, population status, and distribution (including a polygon map).
