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.
