Banded Antennae

Banded Antennae
Alexandria, Fairfax County, Virginia, USA
June 18, 2009
A smallish Hymenoptera, but not too tiny. Is it an ichneumon?

Perhaps Theronia hilaris?

Matching specimens key to Barytarbes, but I would lack confidence in the correctness of that placement until I see specimens of this common species with a species identification that coincides with one of the several described species that Townes referred to this genus in 1970.

Moved from Ichneumon Wasps.

I'll keep an eye out for more.

I have an inkling that this is a species of the subfamily Ctenopelmatinae. Hopefully, I will encounter an identified specimen of the species in the National Collection. If I see an unidentified one instead, keying it to genus might be difficult or impossible because the keys to genera of Ctenopelmatinae that I have tried are almost impossible to use. No groups of ichneumonids are easy, but I find the Ctenopelmatinae especially difficult.

Thanks for the thought.
I've noticed on here that Ichneumonids are difficult to ID - too bad for me, since I seem to encounter a lot.

i think it might be one. i remember reading that they often have bands on their aentenna. i'm sorry i cant help id it any further than that. There are upwards of 3,3000 ichneumons in North America alone. amazing huh?

I thought I remembered reading that, too.
Well, that narrows it down a LITTLE bit! Thanks.
