Hi!
Unfortunately I can't help much, even worse I am not even sure about the Chrysis mediata subgroup. The ovipositor is just not fully extended and I don't think its length can estimated from these photos. Therefore it may belong the C. mediata subgroup but it may also belong to the group of the closest relatives of C. ignita, like C. imressa, C. schencki, C. ignita etc. However there are numerous species, which can be excluded like: C. angustula, C. longula, C. subcoriacea, C. leptomandibularis, C. brevitarsis, C. pseudobrevitarsis.
Unfortunately I can't help more.
