Comment

Karlin and Guttman, 1986, Herpetologica, 42: 283–301, reported on genic variation in Desmognathus fuscus (as including Desmognathus fuscus conanti) and noted that northern (Desmognathus fuscus fuscus) and southern (Desmognathus fuscus conanti) populations may not represent a single species. Titus and Larson, 1996, Syst. Biol., 45: 451–472, subsequently recognized Desmognathus conanti as distinct. Petranka, 1998, Salamand. U.S. Canada: 176, continued to recognized Desmoganthus conanti as a subspecies of Desmognathus fuscus. Bonett, 2002, Copeia, 2002: 344–355, studied the contact zone in Tennessee of Desmognathus conanti and Desmognathus fuscus and confirmed the distinctiveness of these species and further noted that Desmognathus conanti might be a composite of two species, one in northeastern Alabama to South Carolina and the other in western Kentucky to northern Alabama and southwest-central Mississippi. Kozak, Larson, Bonett, and Harmon, 2005, Evolution, 59: 2000–2016, provided a molecular phylogenetics study that suggested four species under this name. Graham, Timpe, and Giovanetto, 2008, Herpetol. Rev., 38: 494-495, provided a record for Marion County, Georgia, USA, the southernmost record in that state. Means and Bonett, 2005, in Lannoo (ed.), Amph. Declines: 705–706, provided an account containing a detailed summary of the literature and range. Beamer and Lamb, 2008, Mol. Phylogenet. Evol., 47: 143–153, reported on phylogenetics of Desmognathus on the Gulf Coastal Plain and redelimited the species and its range. See comment under Desmognathus fuscus regarding complex molecular and morphological patterns in eastern Tennessee. Tilley, Bernardo, Katz, López, Roll, Eriksen, Kratovil, Bittner, and Crandall, 2013, Ecol. Evol., 3: 2547–2567, suggested that populations in eastern nominally of this species of unique mtDNA genomes, suggesting cryptic species. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 427, provided a brief account, photograph, and range map. Altig and McDiarmid, 2015, Handb. Larval Amph. US and Canada: 13, provided an account of larval morphology.
