Hi Günter
Ichneumon bucculentus is not common at all in the UK but I followed your lead and found a number of likely candidates. https://www.gbif.org/species/5030282
I. albiger
I. suspiciosus - https://www.bioimages.org.uk/html/Ichneumon_suspiciosus.htm
I. extensorius - https://www.bioimages.org.uk/html/Ichneumon_extensorius.htm
I. confusor - https://www.bioimages.org.uk/html/Ichneumon_confusor.htm
The hind femur and tibia are "highly enlarged" as per https://www.bioimages.org.uk/html/r170684.htm?4 this could indicate I. confusor or I. albiger - It is suggested here that males are indistinguishable - https://www.bioimages.org.uk/html/Ichneumon_albiger-confusor.htm
I think I am stuck with Inchneumon sp. :o
Thanks for your help, Gareth
