Ciao,
n° 2792 (♀) captured in Cne : St-Germain-du-Bois (Dépt. Saône-et-Loire - France) - 07.06.1994

One uses the keys (which I already sent to the forum) here after :
download/file.php?id=47394&mode=view and download/file.php?id=47396&mode=view
One finds that it is a Tenthredininae .
According to Benson p.109/112 : one is in the presence of a Tenthredopsis, because :

The 1st tergite does not have a medial furrow (which I could not photo because of the poor quality of my camera)

Now I will take the keys of Blank & Ritzau :
One observes that :

- The Clypeus is regularly emarginated (To see photo) and not wrinkled .
- The Hypopygium is very large, this is characteristic of the species (To see photo of ventral apex of abdomen)

Thus this species is T. litterata
In addition the last tergites being red, it is about the variety varia (Gmelin 1790) (see also: Weiffenbach - fig. 2 p.41, with the name of T. carbonaria varia).
Finally :
Tenthredopsis litterata (Geoffroy 1785) var. varia (Gmelin 1790) (♀)
T. litterata vive anche in Italia (Ma var.varia ...?)
