Abstract A comparison of syntypes and a large series of specimens of Xyleborus impressus Eichhoff with specimens of X. ferrugineus (Fabricius) clearly showed the distinct validity of these two species that were previously considered synonyms. Specimens of X. impressus from 14 states in the US were examined, along with syntypes located in museums in Poland and Washington, DC. A lectotype for X. impressus is designated.
