Abstract: Members of the subgenus Nessus Reichardt, 1932 of the genus Hypocaccus C. Thomson, 1867 from Central Europe are revised based on examination of the type material. A nidicolous new species Hypocaccus (Nessus) hungaricus sp. nov. is described and figured. Saprinus curtus Rosenhauer, 1847 is transferred to the subgenus Nessus Reichardt, 1932 of the genus Hypocaccus C. Thomson, 1867. Hypocaccus (Nessus) puncticollis (Küster, 1849) is synonymized with Hypocaccus (Nessus) curtus (Rosenhauer, 1847) syn. nov., based on examination of the type material. A neotype for Hister [= Hypocaccus (Nessus)] rufipes Kugelann, 1792 is designated. Lectotypes and paralectotypes of the following taxa are designated herein: Hister rufipes Paykull, 1798, Saprinus curtus Rosenhauer, 1847, Saprinus puncticollis Küster, 1849, Saprinus arenarius Marseul, 1855, Saprinus longistrius Marseul, 1855, Saprinus cribellaticollis Jacquelin du Val, 1858, Saprinus sicanus Marseul, 1862, Saprinus revisus Marseul, 1876, and Hypocacculus (Nessus) controversus G. Müller, 1937. All species are redescribed and provided with images and male genitalia drawings. A key to the species is given. Hypocaccus (Nessus) controversus is newly reported from Cyprus, and Hypocaccus (Nessus) rufipes is newly reported from Turkey.
