I was going by v belov's ID but I see that this is a carbon copy of the one IDed as Diplazon laetatorius. You are right. Your move or mine? Do you know anything else about this species that we could add to the info page?

Here is some info given to me:
"Diplazon laetatorius (Fabricius): (Ichneumonidae: Diplazontinae). This species likely has the greatest geographic range of any ichneumonid (and perhaps any hymenopteran) having been recorded from the Canadian Arctic to Argentina, from Norway to South Africa and Japan to New Zealand including many remote oceanic Islands. As with the subfamily, the vast majority of host records of D. laetatorius are from Syrphidae (20 genera). Its wide range is likely a result of human agriculture that has spread it along with aphids and aphidophagous syrphids. Because it parasitizes aphidophagous syrphids it can be considered a pest. It is thelytokous throughout most of its range and males are extremely rare. "

I added it to the info page. Found a couple of links.
