Xenopygus Bernhauer is one of the most colorful staphylinid beetles and widespread in the Neotropical region. The aim of this study was to test the monophyly of Xenopygus based on adult morphology and to review the current species. Cladistic analysis was performed with six ingroup species, including two new species.
