Dear colleagues,
please, help to ID one specimen:
female, 8,5 mm, reared from the nest of Eumenid wasp in the Crimea (Ukraine).
It obviously belongs to Cornuchrysis and to cerastes-goup within it.
I think it is Chrysis cerastes Ab., 1877, though species of this group are hard for ID for me.
Can anyone confirm? or it is other species?
Thanks for the attention,
Kate
