Revision of the Quedius fauna of Middle Asia (Coleoptera, Staphylinidae, Staphylininae)

Twenty eight species of the genusQuediusfrom Middle Asia comprising Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan, are revised.QuediusaltaicusKorge, 1962,Q.capitalisEppelsheim, 1892,Q.fusicornisLuze, 1904,Q.solskyiLuze, 1904 andQ.cohaesusEppelsheim, 1888 are redescribed. The following new synonymies are established:Q.solskyiLuze, 1904 =Q.asiaticusBernhauer, 1918,syn. n.;Q.cohaesusEppelsheim, 1888 =Q.turkmenicusCoiffait, 1969,syn. n., =Q.afghanicusCoiffait, 1977,syn. n.;Q.hauseriBernhauer, 1918 =Q.peneckeiBernhauer, 1918,syn. n., =Q.ouzbekiscusCoiffait, 1969,syn. n.;Q.imitatorLuze, 1904 =Q.tschinganensisCoiffait, 1969,syn. n.;Q.novusEppelsheim, 1892 =Q.dzambulensisCoiffait, 1967,syn. n.,Q.pseudonigricepsReitter, 1909 =Q.kirklarensisKorge, 1971,syn. n.Lectotypes are designated forQ.asiaticusBernhauer, 1918,Q.fusicornisLuze, 1904,Q.hauseriBernhauer, 1918,Q.imitatorLuze, 1904,Q.novusEppelsheim, 1892 andQ.solskyiLuze, 1904. For all revised species, taxonomy, distribution and bionomics are summarized.Quediusfuliginosus(Gravenhorst, 1802),Q.sundukoviSmetana, 2003 andQ.pseudonigricepsReitter, 1909 are recorded for Middle Asia for the first time. One species from theQ.coloratus-group, found to be new to science is not described due to shortage of material. Another possibly new species is tentatively identified asQ.fulvicollisStephens, 1833 until the taxonomy of that widespread species is revised. An identification key to all species is provided.
