Hist. Misc., 23: 1-3, noted a probable syntype in the MDUG. Type locality: "laguna de Pátzcuaro", Michoacán, Mexico, 2055 feet altitude.

Bathysiredon dumerilii queretarensis Maldonado-Koerdell, 1948, Mem. Rev. Acad. Nac. Cienc. Antonio Alzate, 56: 199. Syntypes: MDUG (2 specimens), by original designation. Now lost according to Flores-Villela, Ríos-Muñoz, Magaña-Cota, and Quezadas-Tapia, 2016, Zootaxa, 4092: 45, who discussed the types, type locality, and the taxonomic status of the taxon. Type locality: "San Juan del Río (Q[uereta]ro)", Mexico.

Comment

See account by Brandon, 1992, Cat. Am. Amph. Rept., 532: 1-3. See comment under Ambystoma ordinarium. Raffaëlli, 2007, Les Urodèles du Monde: 88, provided a brief account, figure, and map. 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: 545. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 100, provided a brief account, photo, and map.
