Xanthopygina
Xanthopygina is a subtribe of rove beetles (Staphylinidae) containing approximately 334 species distributed across the Neotropical region from the southern United States to Argentina. Species within this subtribe are frequently encountered in tropical forests and can be abundant in various microhabitats. The subtribe has been the subject of extensive taxonomic revision due to historically poorly defined genera, particularly the genus Gastrisus, which accumulated morphologically disparate species without clear diagnostic boundaries. Recent phylogenomic studies have resolved relationships within Xanthopygina, identifying nine major lineages and clarifying generic limits.
