In his handbook of Canadian and U.S. Psocoptera, Mockford (1993) indicates this is the only species in the genus in his study area. The genus is also a Neotropical one, with several species that look similar to P. corruptus.
In the main part of its range, this species is found from Iowa, Quebec, and Nova Scotia, south to Georgia and Alabama. Mockford (1993) states that Mexican barklice of this general appearance may prove to be P. corruptus. The species is also found along the west coast of North America, from British Columbia to Santa Cruz County, California. The eastern and western ranges are disjunct.
