family: Plethodontidae
subfamily: Plethodontinae
genus: Plethodon
 
Taxonomic Notes: This taxon, known only from two poorly preserved specimens, one subsequently destroyed is of questionable validity. Himes and Beckett's (2014, Southeastern Naturalist 24: 103-110) morphological studies led them to consider the taxon synonymous with the syntopic Plethodon mississippi. Pierson et al. (2020, J Herpetology 54:137-143) questioned their findings, but were unable to obtain suitable material for molecular studies and confirmed the demineralization of the skeleton that makes skeletal comparisons impossible. They state "we tentatively recommend continued recognition of P. ainsworthi as a valid but possibly extinct taxon".

Une énigme. Connu de deux exemplaires en alcool prélevés dans une propriété du Mississippi. Les types sont en mauvais état, et il n’a pas été possible d’en retrouver (Highton, com. pers.). Le propriétaire des lieux est décédé depuis. Peut-être un membre du complexe glutinosus. Décrit de 3,5km au sud de Bay Springs, comté de Jasper, Mississippi. Considéré comme éteint (EX) par l’UICN.
