Hi Alex, good question. I excluded Chrysis ragusae for its distribution, because it is known for Mediterranean countries ... the general habitus is really important to discrimate these species. Chrysisindigotea is a relatively robust and large species in the ignita group (7-9mm), whereas ...
It's not Chrysis ragusae then?, I'm acutally not sure how they differ apart from general "habitus". I suppose the length of the antennal segments differ from the ignita-group.
Sorry Mayke, it was late at night and I simply reply to the question in the title Yes, it is Chrysisindigotea. Trichrysis cyanea has only three teeth on the apical margin of the abdomen and Chrysis iris is much larger and darker.
