Known definitely only from the type locality (Cascade Cavern, near Boerne, Kendall County, Texas, USA) (see comment).


Removed from the synonymy of Eurycea neotenes by Chippindale, 2000, in Bruce et al., Biol. Plethodontid Salamanders: 161, where it had been placed by Sweet, 1984, Copeia, 1984: 438 (who regarded the holotype as a hybrid). Chippindale (and Chippindale, Price, Wiens, and Hillis, 2000, Herpetol. Monogr., 14: 1–80) noted a number of likely undescribed species (as the Eurycea latitans complex) related to this form found throughout the southeastern region of the Balcones Escarpment in Texas, USA. Literature of Eurycea latitans reviewed by Brown, 1967, Cat. Am. Amph. Rept., 34: 1–2. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 239, provided a brief account, photograph, and map. Chippindale, 2005, in Lannoo (ed.), Amph. Declines: 746–747, provided a detailed account that summarized the biology and conservation literature. See map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 572. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 110–111, provided an account of larval morphology and biology. Devitt, Wright, Cannatella, and Hillis, 2019, Proc. Natl. Acad. Sci. USA, 116: 2624–2633, reported on the phylogenetic relationships and aquifer loyalty of this species.
