Reviewed by Ashton, 1990, Cat. Am. Amph. Rept., 456: 1-2. 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.
