See accounts by Ashton, 1990, Cat. Am. Amph. Rept., 456: 1–2, and Petranka, 1998, Salamand. U.S. Canada: 422–425. See also Ashton, Braswell, and Guttman, 1981 "1980", Brimleyana, 4: 43–46, for evidence in support of the distinctiveness of this taxon from Necturus maculosus and Necturus punctatus. Brode, 1970, Dissert. Abstr. Internatl., Ser. B, 30: 5288–5289, suggested that Necturus lewisi (as Necturus maculosus lewisi) and Necturus maculosus (as Necturus maculosus maculosus) formed an intergrading series of populations. See also Guttman, Weigt, Moler, Ashton, Mansell, and Peavy, 1990, J. Herpetol., 24: 163–175, for geographic variation in allozymes. Braswell, 2005, in Lannoo (ed.), Amph. Declines: 868–870, provided a detailed account that summarized the biology and conservation literature. See statement of geographic range, habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 641. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 217–218, provided a brief account, photograph, and map. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 127–128, provided an account of larval morphology and biology. Nelson, Niemiller, and Fitzpatrick, 2017, J. Herpetol., 51: 559–566, reported a population of Necturus aff. lewisi from the western side of the Appalachian range in eastern Tennessee, which seemingly is involved in ongoign hybridization with Necturus maculosus.
