Subgenus Nialus Mulsant et Rey, 1870

33. A. varians Duftschmid, 1805 [= niger

(Panzer, 1797)]

Bercio & Folwaczny 1979 ( varians Dft. and niger Panz. ).

Voucher specimens: 4 [23 km of the Curonian Spit, 30 May 2009; ibidem, 20 May 2012; Yantarny, 02 June 2014; Cherniakhovsk, 25 May 2018].

Kaliningrad Region: Chern. (Insterburg), Gur. (Metgethen, Dammhof, Forst Fritzen), Gur. (Königsberg for „ varians Dft. “), Zel. (Loppöhnen, Neuhäuser, Pillau, Rauschen, Rossitten).

Comments: The species names A. niger (Panzer, 1797) and A. niger Illiger, 1798 are considered homonyms and the specific name A. niger Illiger, 1798 for a widely distributed and endangered species of European dung beetle is conserved by suppression of other name ( Krell et al. 2003). Panzer’s actual species is considered to be conspecific with A. varians Duftschmid, 1805 ( Tamutis et al. 2011). All data

from catalogue of Bercio & Folwaczny (1979) is united under name A. varians . The species is considered to be sporadically occasional in the Region.
