GENUS † CRETOQUEDIUS RYVKIN, 1988 View in CoL

† CRETOQUEDIUS INFRACTUS SOLODOVNIKOV & YUE, 2013 View in CoL

† Quedius cretaceus Cai & Huang, 2013 View in CoL syn. nov. Comments

The identical proportions of the body and antennal segments, eye size and habitus, plus the fact that the two taxa are from the Yixian Formation of China, justify the synonymy of † Quedius cretaceus Cai & Huang, 2013 View in CoL with † Cretoquedius infractus Solodovnikov & Yue, 2013 View in CoL . The potential synonymy was mentioned earlier by Chatzimanolis (2018) based on consultation with the senior author. Both names became available with the print versions of their respective article (both August 2013) and as neither has objective priority over the other, we act as first reviser and choose † Cretoquedius infractus Solodovnikov & Yue, 2013 View in CoL to have priority over † Quedius cretaceus Cai & Huang, 2013 View in CoL , because the former was originally described in the currently accepted genus. This taxon represents the most complete fossil of † Cretoquedius View in CoL and was resolved as stem Staphylinini View in CoL by the present analysis. However, the other members of the genus, including the type species, require re-study. At least some of these might be shown to belong to crown group Staphylinini View in CoL .
