Moved
Sundry characteristics indicate this group, and although the apical tarsomeres aren't easy to see in this photo, it does appear, that they are enlarged.

Moved from Ichneumon Wasps.

Other views
I have several photos of this wasp. If you tell me what body part an apical tarsomere is, I'll try to find one that has it in better focus. Am I looking for, like, ankles or eyebrows?

Feet
The tarsi are the feet, and the tarsomeres are the joints of the feet. In the Polysphincta genus group, the apical joint of the tarsus is swollen. I don't recall having seen any speculation about the functionality of this, but I suspect it could have something to do with not getting entangled in spider silk.
