Ichneumons wasp

I checked some Ichneumonidae of UK, but did not find a reasonable match. Personally I do not think this is Ichneumon molitorius. This one should have white antennae part and yellowish femurs: http://eol.org/pages/3758764/overview Just to show you the complexity of only Ichneumonidae in UK: http://www.brc.ac.uk/downloads/Ichneumonidae_checklist.pdf Key issue would be white spot on the head, colors of the femurs, tibias and feet (!), antennae color. A tremendous variability!! My closest guess/hint would be: Cratichneumon sicarius, without being that confident, colors are somehow different... I admit I have to capitulate, wasps are not really my business...
