Zusammenfassung:The second species of Pseudactium Casey from Arkansas, P. ursum, new species, is described from three male specimens collected in mature deciduous forest near the Buffalo River, Newton County. Pseudactium ursum resembles P. parabolicum, but differs in anatomical details of the trochanters, abdomen, and aedeagus. A modification to a recently published key is provided that allows separation of P. ursum from the ten other described species of Pseudactium. Pseudactium ursum is the only known pselaphine species that is precinctive to the Ozark Plateau.
