Hi Marco,
thank you for your comment, though it leaves me somewhat insecure as to how to understand your statement "Tremulicerus dimitiatus (should be moved to Metidiocerus most probably)" .
Also, I have to tell you that Herbert Nickel is one of the formost experts for our region and therefore I think he - as much as I - would like to hear your reasons why you don't believe it to be Metidiocerus impressifrons.
Again, thank you for your involvement.
Best regards,
Konrad
P.S. Sorry, Marco, I only now saw that you have addressed Herbert yourself...
