Abstract: The systematics of the staphylinid subfamily Oxytelinae Fleming, 1821 are investigated. Phylogenetic relationships among the Carpelimus group of genera (Blediotrogus, Pareiobledius, Mimopaederus, Teropalpus, Ochthephilus, Carpelimus, Xerophygus, Trogactus, Thinodromus) are analyzed using 70 characters (most previously unstudied) and 45 exemplar taxa from the subfamily. Based on the results of this analysis, a hypothesis of the relationships among the genera and tribes of Oxytelinae is presented. The following new synonymies are proposed: Thinodromus Kraatz, 1857 = Apocellagria Cameron, 1920, syn. n.; Aploderus Stephens, 1833 = Bledioschema Smetana, 1967, syn. n. The tribe Planeustomini Jacquelin du Val, 1857 is to include the genera Manda Blackwelder, 1952 and Planeustomus Jacquelin du Val, 1857. The limits of the tribe Oxytelini are expanded to contain the former Thinobiini J. Sahlberg, 1876 less Blediini Ádám, 2001, with the latter being recognized as a valid taxon. The problems with generic limits in the tribe Oxytelini are addressed. Based on the character variability found throughout the whole tribe, new definitions for Oxytelus Gravenhorst, 1802 and Anotylus Thomson, 1859 are proposed, resulting in the following synonymies: Oxytelus Gravenhorst, 1802 = Hoplitodes Fauvel, 1904, syn. n., = Anisopsis Fauvel, 1904, syn. n., = Paroxytelopsis Cameron, 1933, syn. n., = Anisopsidius Fagel, 1960, syn. n.; Anotylus Thomson, 1859 = Oxytelopsis Fauvel, 1895, syn. n., = Rimba Blackwelder, 1952, syn. n. The state of knowledge on the larvae of the subfamily (with attention to tribal classification) is summerized. A new key for genera of Oxytelinae is presented. In order to use them in the phylogenetic analysis, 5 new species are described: Xerophygus hreblayi sp. n., Carpelimus bifidus sp. n., Thinodromus juanfernandezianus sp. n., Thinodromus schillhammeri sp. n., Trogactus ocellatus sp. n. With 129 figures and one table.
