Comment

Removed from the synonymy of Dicamptodon ensatus by Daugherty, Allendorf, Dunlap, and Knudsen, 1983, Copeia, 1983: 679, on the basis of electrophoretic distance. Nussbaum, Brodie, and Storm, 1983, Amph. Rept. Pacific Northwest: 67, rejected the specific distinctness of this form on the basis of overall similarity to Dicamptodon ensatus but the taxon was recognized on the basis of molecular evidence by Good, 1989, Evolution, 43: 728–744. Petranka, 1998, Salamand. U.S. Canada: 146–147, Stebbins, 2003, Field Guide W. Rept. Amph., Ed. 3: 159, and Raffaëlli, 2007, Les Urodèles du Monde: 73, provided brief accounts. Lohman and Bury, 2005, in Lannoo (ed.), Amph. Declines: 651–652, provided a detailed account. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 87–88, provided a brief account, photo, and map. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 96–98, provided an account of larval morphology. Raffaëlli, 2022, Salamanders & Newts of the World: 135, provided an account, summarizing systematics, life history, population status, and distribution (including a polygon map).
