Eutanyacra suturalis??

Eutanyacra suturalis??
Bellevue, King County, Washington, USA
July 14, 2017
On grass inflorescence... bug... or sector... maybe resting. This may be true of many wasps, or wasps in this family (whichever that is), but I notice two prong-like projections about 2/3 of the way back on the lower abdomen that I had not noticed before (on both pictures). Antennae seem a bit unique in terms of segments, transitioning color, and what appears to be a almost continual but very slow tapering (very extended conical shape).

Pics were taken late day, perhaps shortly after sunset, so color was enhanced and may not be a perfect match.

Eutanyacra suturalis?? Eutanyacra suturalis??

Moved from ID Request.

Female - Ichneumonini
The two "prong-like projections" that you noticed are the apical spines of the hind tibiae. (left side showing from behind abdomen)
This might be a female in the genus Eutanyacra, but I'm not sure. The blunt abdomen is too fat for a male. = ♀
Please compare Eutanyacra suturalis: ♀ That may be an eastern species and I'm not sure of the exact range. Note, the yellow coloring on the edges of the sternal segments.

 
Eutanyacra suturalis??
Thanks for the feedback / suggestion!

It really does look like Eutanyacra suturalis, although that species has no entries in the entire lower 48 within BG, with the only entry in BG being from "Trinity Bay, Newfoundland/Labrador, Canada". I could not be much farther away from that location!

I did find that EOL had four listings, in 3 states (1-NY; 2-IL, 1-TX)... but not sure how accurate that data is (see Eutanyacra suturalis at EOL).


Looked at all of this tribe's postings for WA, but hardly any go below tribe (one of my 3 entires does: Ichneumon concentrator).

Reviewed all genus entries below this tribe, but only 3-4 even show states with posts out west. None of them look as close as a match as your suggested Eutanyacra suturalis. Those that looked similar at all, appeared to have a completely orange thorax, and different antennae. [i[E. suturalis[/i] has black flow the top of the thorax and orange on top like my specimen, not to mention antennae of same apparent length with same apparent color transition I saw on no others.

I think I might have started going through all the genus listed under Ichneumonini before for my original entry categories here, but was thrown off not finding much of anything out west. (Wish I had given that more thought, as I did see some with several characteristics of my other submitted under my other Ichneumonini.)
