Short summary
Two new fossil species of turtle beetles have been identified from inclusions in Baltic amber (approx. 41–38 million years old). These beetles are the first described representatives of the family from this amber type and the first known turtle beetles from Europe. The paper also contains a discussion about possible association of the fossil turtle beetles with orchids in the Eocene amberiferous forest and remarks concerning fossil beetles of the group.
