A new species of the genus Platynus Bonelli, P. daviesi, is described from specimens collected in the Appalachian Mountains. The species is structurally most similar to P. parmarginatus Hamilton but differs inthe coloration of the body dorsally darker on average, the elytra proportionally longer and wider, the vertex and disc of pronotum with well impressed microsculpture, the elytral interval 3 with four or five discal setae in most specimens, and the median lobe of aedeagus less curved overall. DNA barcoding was performed on several species of eastern North American Platynus species and P. daviesi was found to be genetically distinct from P. parmarginatus. A key to the 12 species of Platynus found east of the Mississippi River is provided.
