(52). C. (s. str.) schreberi (Linnaeus, 1767)

Lentz 1879 ( Onthophagus); Bercio & Folwaczny 1979.

Kaliningrad Region: Bagr. (Heiligenbeil, Ludwigsort), Chern. (Insterburg), Gur.

(Königsberg, Wilkie), Nest. (Rominten), Zel.

(Rauschen).

Comments: Psammophilous species. Formerly widespread and abundant beetle [according to Bercio & Folwaczny (1979): „Insterburg, in jedem Jahr unter jedem Kuhfladen“, that is “Insterburg, every year under every cow pat”] with evident decline of populations and probably decrease of distributional range. The actual presence in the Region needs confirmation. The species is known in Belarus (Alexandovitch & Pisanenko 1991), all three Baltic States and eastern Fennoscandia (Silfverberg 2010). The range of this beetle reachs its northern limits around 56˚ north latitude (Kabakov 2006).
