Resumen:
Total evidence phylogenetic analysis and systematics of Staphylinini: focus on mega-diverse "Staphylinini propria" M. R. Chani-Posse, A. J. Brunke, S. Chatzimanolis, H. Schillhammer and A. SolodovnikovStaphylinini is a hyperdiverse globally distributed rove beetle tribe with its most speciose branches clustered in the so-called "Staphylinini propria" clade that until present united subtribes Staphylinina, Anisolinina, Philonthina, Xanthopygina, and a number of genera incertae sedis. Current classification of "Staphylinini propria" remains largely artificial and the systematic position of the most diverse genera within the most speciose subtribe Philonthina is unclear. Sister-group relationships of the morphologically highly modified genus Holisus and, therefore, the status of its respective subtribe Hyptiomina are not resolved within Staphylinini. To remove current inconsistencies related to the poorly known evolutionary relationships within "Staphylinini propria", Philonthina, and affinities of Holisus, we performed an extensive phylogenetic study including adult morphology and DNA markers. Our analyses confirm "Staphylinini propria" as a natural group composed by seven lineages. Four of them correspond to the earlier established subtribes Anisolinina, Philonthina, Staphylinina, and Xanthopygina. Three lineages, such as the Oriental Rientis, Neotropical Philothalpus, and Oriental Algon + Barypalpus (to be removed from synonymy with Rientis) may constitute three new subtribes, respectively. Hyptiomina is found to be a member of the South Hemisphere stock of Staphylinini whose evolution is associated with Gondwana. Based on our new phylogeny the composition and internal relationships among genera of Philonthina are revised and possible solutions for better limits of such currently poorly defined genera as Belonuchus, Cafius, Hesperus, Gabrius and Philonthus are discussed.
