another long ovipositor with a wasp attached -

Rockville, Montgomery County, Maryland, USA
September 7, 2019
Size: forewing 5.5mm

This one keys out to Banchinae using Wahl's GIN subfamily key (1) but I can't find any accessible papers describing how to distinguish between the 3 Banchinae tribes let alone anything that contains a key to species. Is there anything newer than the Townes' American Entomological Institute and US National Museum volumes?
If it helps with an ID, I can upload full size images to Flickr and post a link here
Thanks in advance

(I've uploaded a lot of photos of this wasp; free to frass what's not useful for the guide.)

Moved from Ichneumon Wasps.

Atrophini…

In most Atrophini, the ovipositor has a well-developed subapical notch that can be seen in image 12 of your sequence. The forewing 2m-cu vein either has a single bulla, or has two bullae which are very close and separated by a short section of a vein, which is about as long as, or shorter than either bulla (image 10 of your sequence). The propodeum usually has a posterior transverse carina present, which is close to the hind end near the metasomal insertion (image 6 of your sequence).

Unfortunately, I am not aware of any online references for the various tribes of this group, relying instead on some texts that I have for descriptions.

See reference here.

Thanks Ross

Are there any text you'd recommend I obtain? I haven't bought the older Townes AEI memoirs but they seem, along with the Dasch volumes, to be pretty much all there is. I'd like to try to get some of my ichneumon posts ID'd beyond subfamily or tribe (emphasis on "try" because I don't think I'll succeed too often).
