Comment

In the Plethodon glutinosus group, according to the original publication. Petranka, 1998, Salamand. U.S. Canada: 355, rejected the distinction from Plethodon glutinosus on the basis of overall similarity. Beamer and Lannoo, 2005, in Lannoo (ed.), Amph. Declines: 825–826, provided a detailed account that summarized the biology and conservation literature. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 399, provided a brief account, photograph, and range map. Plethodon ainsworthi, as originally diagnosed, was not obviously related to any other PlethodonLazell, 2005, in Lannoo (ed.), Amph. Declines: 787–788, provided a account of Plethodon ainsworthi that summarized the biology and conservation literature. Raffaëlli, 2007, Les Urodèles du Monde: 293, suggested that Plethodon ainsworthi is a member of the Plethodon glutinosus complex. See photograph, map, description of geographic range and habitat, and conservation status  of Plethodon ainsworthi in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 144, who regarded the species as extinct. Fouquette and Dubois, 2014, Checklist N.A. Amph. Rept.: 192, suggested that Plethodon ainsworthi is a member of the Plethodon yonahlossee group, but provided no evidence for this conjecture. Raffaëlli, 2013, Urodeles du Monde, 2nd ed.: 388, provided a brief account, photograph, and range map of Plethodon ainsworthi. Himes and Beckett, 2013, Southeast. Nat., 12: 851–856, presented morphometric evidence that Plethodon ainsworthi is a junior synonym of Plethodon mississippi. Highton, Bonett, and Jockusch, 2017, in Crother (ed.), Herpetol. Circ., 43: 30, recognized Plethodon ainsworthi for undisclosed reasons.
