Reviewed by Anderson, 1975, Cat. Am. Amph. Rept., 164: 1–2. Highton, 2000, in Bruce et al., Biol. Plethodontid Salamanders: 221, on the basis of the mtDNA data of Shaffer and McKnight, 1996, Evolution, 50, suggested that Ambystoma ordinarium might be two species, and that one of these might be conspecific with Ambystoma dumerilii. Matias-Ferrer and Murillo, 2004, Herpetol. Rev., 35: 182–183, provided the record from the state of México, Mexico. Weisrock, Shaffer, Storz, Storz, and Voss, 2006, Mol. Ecol., 15: 2489–2503, discussed the effects of introgression with Ambystoma dumerilii and that evidence from nuDNA suggests that Ambystoma ordinarium consists of one species with populations that have at various time introgressed other species' mtDNA and that Ambystoma dumerilii is otherwise only distantly related. See map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 546. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 102–103, provided a brief account, photo, and map. Escalera-Vazquez, Hernández-Guzmán, Soto-Rojas, and Suazo-Ortuño, 2018, Herpetologica, 74: 117–126, discussed the potential range of the species, and Hernández-Guzmán, Escalera-Vazquez, and Suazo-Ortuño, 2019, Herpetol. J., 29: 71–81, discussed the potential range in light of climate change. Hernandez, Raffaëlli, Jelsch, Rosas-Espinoza, Santiago-Pérez, and Nuñez, 2019, Herpetol. Bull., London, 147: 15–21, reported on range, habitat, and conservation.
