Rove beetle subtribes Quediina, Amblyopinina and Tanygnathinina: systematic changes affecting Central European fauna (Coleoptera, Staphylinidae, Staphylinini)

In preparation for the new edition of the identification keys of rove beetles of Central Europe (Volume 4 of the "Die Käfer Mitteleuropas"), the following systematic problems affecting the Central European fauna of the tribe Staphylinini are addressed: phylogeny-based, new concepts for the subtribes Quediina and Amblyopinina; status of the subtribe Tanygnathinina; systematic position of the genus Astrapaeus; status of Quedionuchus, the subgenus of Quedius; identity of some species of Quedius and Heterothops. As a result, new wordwide and Central Europe-based diagnoses are given for the subtribes Quediina and Amblyopinina; earlier recognized but not widely accepted synonymies of the genera Quedius and Velleius, and of the species Heterothops praevius and Heterothops niger, are justified; new synonyms are established for: Quedius pseudonigriceps Reitter, 1909 (= Quediusnoricus Bernhauer, 1927, syn. n.); Quedius maurorufus (Gravenhorst, 1806) (= Quedius richteri Korge, 1966, syn. n.); Quedius suturalis Kiesenwetter, 1845 (= Quedius merlini Drugmand & Bruge 1991, syn. n.); lectotypes are designated for Quedius meridiocarpathicus Smetana, 1958, Quedius noricus Bernhauer, 1927, and Quedius pseudonigriceps Reitter, 1909. As a result of synonymy of Quedius and Velleius, the following new combinations are proposed: Quedius amamiensis (Watanabe, 1990), comb. n.; Quedius circumipectus (Cho, 1996), comb. n.; Quedius elongatus (Naomi, 1986), comb. n.; Quedius japonicus (Watanabe, 1990), comb. n.; Quedius pectinatus (Sharp, 1874), comb. n.; Quedius setosus (Sharp, 1889), comb. n.; Quedius simillimus (Fairmaire, 1891), comb. n. As a result of new combinations, Quedius japonicus (Watanabe, 1990) (non Quedius japonicus Sharp, 1874) is replaced with the new name Quedius watanabei Solodovnikov, nom. n., while Quedius pectinatus Lea, 1908 (non Quedius pectinatus (Sharp, 1874)) is replaced with the new name Quedius arthuri Solodovnikov, nom. n.
