Comment

The status of this taxon was problematic until recently. Petranka, 1998, Salamand. U.S. Canada: 241–242, continued the recognition of this lineage as a subspecies of Eurycea bislineata (sensu lato, as including Eurycea wilderae and Eurycea cirrigera). Sever, 1989, Bull. Chicago Herpetol. Soc., 24: 70–74, discussed the problem and concluded that Eurycea aquatica is a junior synonym of Eurycea cirrigera, but later Sever, 1999, Cat. Am. Amph. Rept., 684: 4, argued for its recognition. Kozak and Lannoo, 2005, in Lannoo (ed.), Amph. Declines: 734–735, provided a detailed account that summarized the literature. Timpe, Graham, and Bonett, 2009, Mol. Phylogenet. Evol., 52: 368–378, on the basis of molecular evidence, documented the monophyly of this taxon, and suggested that it is the nearest relative of Eurycea junaluska, and composed of at least three genetically distinct populations. Bonett, Steffen, Lambert, Wiens, and Chippindale, 2014 "2013", Evolution, 68: 466–482, confirmed this placement. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 246, provided a brief account, photograph, and map. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 108–109, provided an account of larval morphology and biology.
