Quedius (Raphirus) umbrinus ERICHSON, 1839
Quedius (Raphirus) kuboni ŠTOURAČ, 1998: 15 ff.; nov.syn.
C o m m e n t: Quedius umbrinus previously already had ten junior synonyms, more than any other representative of the subgenus Raphirus STEPHENS, 1829 in the Palaearctic region. The species is widespread and at the same time subject to enormous intraspecific variation (ASSING 2018).
The original description of Q. kuboni is based on a male holotype and eleven paratypes collected in three mountain ranges (Rodopi, Rila, Pirin) in Bulgaria. Based on the illustrations of the aedeagus provided by ŠTOURAČ (1998), the type material is undoubtedly conspecific with Q. umbrinus .
