(1). O. armiger (Scopoli, 1772)

Lentz 1879 ( Odontaeus mobilicornis Fabr. ); Bercio & Folwaczny 1979 ( Odontaeus ).

Kaliningrad Region: Chern. (Insterburg).

Comments: The larvae of the species are probably subterraneous mycetophage, the beetle inhabits meadows adjoining the edges of oak forests, brownfields covered with shrubs, scarcely exploited pastures with old single oaks and oak forests characterized by high sunshine intensity ( Byk et al. 2012). The larvae probably are hydnophagous (e.g. truffle-eating).

The species is known in southern Fennoscandia ( Silfverberg 2010), Poland ( Byk et al. 2012; Bunalski et al. 2013), Lithuania ( Tamutis et al. 2011) and Belarus (Alexandrovitch et al. 1996).
