Comment

This species was shown to be genetically distinct from Dicamptodon ensatus by Good, 1989, Evolution, 43: 728–744, who found a narrow hybrid zone between Dicamptodon ensatus and Dicamptodon tenebrosus in Mendocino County, California. Steele and Storfer, 2006, Mol. Ecol., 15: 2477–2487, reported on phylogeographic patterns. See detailed account by Petranka, 1998, Salamand. U.S. Canada: 152–156. Raffaëlli, 2007, Les Urodèles du Monde: 73–74, provided a brief account. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 88–89, provided a brief account, photo, and map.
