Ichneumon wasp ID please?!

I asked for an ID on an Ichneumon wasp a while ago but the pics were a little unclear. I have managed to take some better photos of a very obliging female Ichneumon wasp doing her chilling thing earlier today.............Can anyone help me identify her exact species please? Thanks!

    Very nice!  It's Helconidea ruspator, one of our larger Braconidae (subfamily Helconinae). This is a parasitoid of cerambycid beetles and rather rarely seen in Britain - it may just be unobtrusive, we know  very little about these helconines.  There are three British helconines with a tooth on the hind femur but this can be narrowed down to H. ruspator as the antenna is all black (white-banded in Wroughtonia spinator), the hind coxa is black and the tibia reddish (reddish and dark brown, respectively, in Helconidea dentator), and the position of the femoral tooth is just right.  I'm assuming this is a British specimen, though...

    Cheers,

    Gavin
