Comment

In the Pseudoeurycea bellii group of Wake and Lynch, 1976, Sci. Bull. Nat. Hist. Mus. Los Angeles Co., 25: 61. Parra-Olea, García-París, Papenfuss, and Wake, 2005, Herpetologica, 61: 145-158, discussed the systematics of the complex. Raffaëlli, 2007, Les Urodèles du Monde: 219-220, provided brief accounts by subspecies, photographs, and map, and considered it to be in the Pseudoeurycea bellii complex of the Pseudoeurycea bellii group. Van Devender, Lowe, and Holm, 1989, Herpetol. Rev., 20: 75, provided a locality in Madrean Chihuahua. Lemos-Espinal, 2007, Anf. Rept. Chihuahua Mexico: 26-27, provided an account for Chihuahua. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 285–286, provided brief account, photographs, and map.
