Dignoptinus, a new genus for fossil Dignomus regiomontanus Alekseev from Eocene Baltic amber, and new status for Bruchoptinus Reitter and Pseudoptinus Reitter (Coleoptera: Ptinidae)

The holotype of Dignomus regiomontanus Alekseev, 2014, from the Eocene Baltic amber (Tertiary, Paleogene), is re-examined and re-described. Dignoptinus gen. nov. is proposed to place this species. Bruchoptinus Reitter, 1884, and Pseudoptinus Reitter, 1884, described as subgenera of Ptinus Linnaeus,...

Zusammenfassung:The holotype of Dignomus regiomontanus Alekseev, 2014, from the Eocene Baltic amber (Tertiary, Paleogene), is re-examined and re-described. Dignoptinus gen. nov. is proposed to place this species. Bruchoptinus Reitter, 1884, and Pseudoptinus Reitter, 1884, described as subgenera of Ptinus Linnaeus, 1767, are the closest relatives of the new fossil genus. These two subgenera are proposed as independent genera: Bruchoptinus Reitter, 1884 stat. nov. and Pseudoptinus Reitter, 1884 stat. nov. Forty-four new combinations for the species of these genera are proposed.
