Hello Jan,
somewhat blurred this photo, especially at the critical points. It seems difficult to decide one even for the male / female.
But the specimens are very similar to the genus Ebaeus (maybe E. flavicornis Er. 1840), and less to Hypebaeus.
Kind Regards from Greece,
George

Hi George, Thank you for the information.I apologize for the bad photo

These herein at both sites, are all females (without pretarsal combs or appendages at elytral apex). Not suitable for safe identification .
In males, the differences of the genera are evident:

Ebaeus: - clear pretarsal comb (well visible at a magnification x40),
           - Two appendages at each elytral apex (the one small, the other large).

Hypebaeus: -without pretarsal comb (or very small, barely visible at a magnification x100).
             - One appendage at each elytral apex.

Furthermore, Hyp. flavipes, does not have as deep notch in the pygidium.
