Ist hier eine Bestimmung möglich?

Hi Horst,

it belongs to the C. ignita species group, but I'm not sure that it is possible to ID from the pictures...
Let's see if someone else can help us with your ID.

Chrysis terminata, a typical spring species which is similar to the true C. ignita, but its more slender and parallel sided, and the most obvious character is the 4 "teeth" on the transverse frontal carina (the ledge between the eyes)

shame on me ...

there is only terminata with this frontal carina in Europe ? I think I saw it in Franche-Comté last week.

Well, its actually not a very typical specimen, I was a bit unsure about it at first. The apical teeth are shorter than they usually are, the second tergite is not as coarsely punctured and the toothed TFC is not as prominent as in "typical" C. terminata

Hello : C. terminata is the only species of ignita Chrysis group which have these teeth on the frontal carina ?

Hello, I am Jérôme, a new member and beginner in chrysidid (I have very intersted in social & solitary wasps, as well) : is Chrysis terminata the only species of ignita group with this prominent frontal carina ?
I have found some chrysidid (2015may 6 & 7)

Herzlichen Dank Alex und Euchroeus. Viele Grüße aus Flensburg

Jérôme,

the frontal carina well developed with four tooth-like tubercles medially is more evident in C. terminata than in other species of the ignita group.
However, when the tubercles are clearly distinct ... well ... very likely you're looking at C. terminata.

A combination of different diagnostic characteristcs should guide you to C. terminata. In this case the frontal carina is similar to that of C. terminata, but other characters not...

Cheers
Paolo
