Xanthopygus
Xanthopygus is a genus of rove beetles (Staphylinidae: Staphylininae) established by Kraatz in 1857. The genus belongs to the subtribe Xanthopygina and is distributed across Mexico, Central America, the West Indies, and South America. A 2022 taxonomic revision by Chatzimanolis updated distributional records, resolved nomenclatural issues including synonymies and type designations, and provided an illustrated identification key for all species. The genus is characterized by distinctive morphological features typical of the Xanthopygina, though specific diagnostic traits vary among species.
