I think the wing venation on this one places it in Microgastrinae but I only see 16 antennal segments. I've got a few more images of this one and can post larger crops of selected regions if that would help.

Thanks in advance for the help

(body length doesn’t include the ovipositor)

Microgastrine

16 flagellomeres is correct for this group. It is a cyclostome and is missing the occipital carina so you have it correct.

thanks but I'm confused

The Whitfield chapter of this reference on braconids says "All Microgastrinae have exactly 18 antennal segments..." (1) which I assumed to mean 16 flagellomeres plus the scape and pedicel. I counted only 16 total on this wasp but may be miscounting.

I count 16

For a total of 18. The second photo you provided is pretty clear. You can't see the pedicle (ringlike band) in the photo but the scape is very pronounced. The flagellomeres are a little difficult to count as they are annulated.

I have been looking for a pdf of that ref. you provided for ever too. My copy is pretty tattered. I can't even find it for sale any where. Thanks!

thanks for taking a 2nd look

I should probably start taking my shoes off to count that high :-)
