Capture in “Forêt de Couloutre” (Dépt.Nièvre) on 27 VI 2015

I had identified a Nematopodius, what is false.
Here is why :

This Cryptinae belongs to the Tribe of Mesostenini.
The characteristics of our capture are in particular :
- Areolet very small
- Areolet with IL & JN parallel or almost parallel [Attention : the drawing, which we joined, of the Areolet is not the one of our capture, but serves only to denominate the Veins]
- M is +/- in the center of LN
- Shape of the Tergite 1, of which Post-Petiole having its side margins almost parallel
- Shape of the Ovipositeur (see our photo)
Only some species of 2 Genus have these characteristics : Mesostenus & Nematopodius

These differ in particular by the position of the spiracles of Tergite 1.
    I have regrettably neglected this characteristic
Besides our capture seems not to have an apical transverse Carina of Propodeum.
Now the drawings of Townes show the presence of a such Carina in Mesostenus, and its absence in Nematopodius.
Of where my erroneous determination.

funebris was also captured in Italy
