Comment

In the Pseudoeurycea bellii group of Wake and Lynch, 1976, Sci. Bull. Nat. Hist. Mus. Los Angeles Co., 25: 61. Uribe-Peña, Ramírez-Bautista, and Casas-Andreu, 1999, Cuad. Inst. Biol., UNAM, 32: 24-25, provided an account and described the distribution. Parra-Olea, García-París, Papenfuss, and Wake, 2005, Herpetologica, 61: 145-158, discussed the systematics of the complex and redefined the species as composed of two widely allopatric and diagnosable subspecies: Pseudoeurycea bellii bellii (Mexican Tableland) and Pseudoeurycea bellii sierraoccidentalis of eastern Sonora and adjacent Madrean Chihuahua (now Isthmura sierraoccidentalis). 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. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 586. Lemos-Espinal and Dixon, 2013, Amphibians and Reptiles of San Luis Potosí: 27, provided an account for San Luis Potosí, Mexico. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 285–286, provided brief accounts by subspecies, photographs, and map. Quintero-Díaz, Sigala-Rodríguez, and Carbajal-Márquez, 2014, Herpetol. Rev., 45: 651, provided a range extension within southern Zacatecas, Mexico, and briefly characterized the range.
