Osoriinae Erichson, 1839

In Germany, Thoracophorus corticinus (2.8 mm) is designated as an Urwald relict species D category 2, which means that this beetle has high environmental requirements (MÜLLER, 2005). With two observations (Voeren – FS9126 and Voeren GS0227), both in an orchard, we cannot endorse this status. Nevertheless, sifting out of five specimens in a dead apple tree, inhabited by the ant L. brunneus , confirms the link between these two invertebrates as mentioned in the literature.
