After seeing the photos Matthias Riedal said: "Although it is easier to identify the females of Coelichneumon because they have more morphological features for comparison, I think that your specimen is a variety of Coelichneumon comitator (Linnaeus): black legs are sometimes occuring in this species, but an unusual feature of your specimen is the strong apical tooth of the fore metatarsus which is usually small or absent in my material."
