Bay Springs Salamander (Lazell, 2005, in Lannoo (ed.), Amph. Declines: 787; Tilley, Highton, and Wake, 2012, in Crother (ed.), Herpetol. Circ., 39: 20; Collins and Taggart, 2009, Standard Common Curr. Sci. Names N. Am. Amph. Turtles Rept. Crocodil., ed. 6: 13; Tilley, Highton, and Wake, 2012, in Crother (ed.), Herpetol.

Known only from the type locality (Jasper County, Mississippi, USA).


Not obviously related to any other Plethodon according to the original publication. Lazell, 2005, in Lannoo (ed.), Amph. Declines: 787–788, provided a account that summarized the biology and conservation literature. Raffaëlli, 2007, Les Urodèles du Monde: 293, suggested that it is a member of the Plethodon glutinosus complex. See photograph, map, description of geographic range and habitat, and conservation status 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 it 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. Tentatively removed from the synonymy of Plethodon mississippi by Pierson, Kieran, Clause, and Castleberry, 2020, J. Herpetol., 54: 137–143 (who considered it possibly extinct), where it had been placed by Himes and Beckett, 2013, Southeast. Nat., 12: 851.  Highton, Bonett, and Jockusch, 2017, in Crother (ed.), Herpetol. Circ., 43: 30, recognized Plethodon ainsworthi for undisclosed reasons.
