It is not possible : in the ignita group on pictures, we can sometimes identify Chrysis terminata (maybe the commonest species in ignita group, and one of the commonest chrysidid in Europa except in mediterranean area).
But here, we can see : it is not a slender species and we can "eliminate" some species (angustula, leptomandibularis)...
For ID a species of the ignita group, we need : lateral view of mandibles, dorsal view of abdomen, sternites, ovipositor, hairs (colour) of the vertex on head.
