These are images of a Potter Wasp, that is most likely a female Euodynerus annulatus imperialis. (subspecies)
This species can be distinguished from both sexes of the very similar looking, western subspecies Euodynerus auranus azotopus, which has the hind margin of T2 slightly to strongly thickened (0.4–1.3x mid ocellar diameter), double-edged and often reflexed.

The key features, such as her shapes, ratios, hair, punctation and textures are all very similar to this female, that I already submitted: (red & yellow colored variety of E. annulatus) ♀
The two, thick black lines on the ventral abdomen (S1) stand out as very unique from the other female and yet they seem to be a normal and natural characteristic on this specimen. I'm including extra views of that area.
