The systematic position of the monotypic genus Beeria Hatch 1957 within the subfamily Staphylininae is discussed. The genus combines characters of both the tribe Staphylinini and Quediini, however the morphology of the prothorax seems to justify its assignment to the tribe Quediini. A detailed description of the genus, together with the presently known data about its distribution and ecology are given. The type species of Beeria (punctata Hatch 1957) is identical with Philonthus nematocerus Casey 1915, which results in the following new combination: Beeria nematocera (Casey 1915) with punctata Hatch 1957 as a junior synonym. The characters distinguishing the tribes Staphylinini and Quediini are discussed in detail. A key to holarctic genera of the tribe Quediini is given. The subtribe Triacri established by Bernhauer (1931) within the tribe Quediini is identical with the subtribe Xanthopygi within the tribe Staphylinini. The genera Algon Sharp, Brachycamonthus Bernh. and Rientis Sharp are removed from the tribe Quediini and reassigned to the tribe Staphylinini, subtribe Xanthopygi. The genus Rientis Sharp, 1874 is identical with Securipalpus Schubert, 1908, which becomes a junior synonym of Rientis.
