These are images of a Thread-waisted Wasp
, that I believe is a male Prionyx atratus
or Prionyx subatratus
. I'm not sure that you can tell them apart without a DNA test.
1) - The wing's submarginal cells are difficult to trace on these wasps and yet sometimes they can be used to verify a genus level ID.
2) - He has a globular shaped abdomen, with 7 segments.
3) - One key feature that I have noticed on several images in this genus (only) is a brown stripe along the inner-ventral margin of the hind tibia.
4) - There are thin, reddish stripes of lightened pigmentation on his foreleg femur's mid-ventral and even thinner stripes on the forward or basal side of his mid & hind coxa & trochanters.
5) - The clypeus has a semicircular depression on the mid-ventral edge & a matching suture line above that. Also some slightly reddish coloration can be seen on his hairy face.
I have posted the female that I filmed later on. Her images can be found here: ♀
