Ciao,

# 2710 captured at an altitude of 1086 m. in Cne : La-Cluse-et-Mijoux (Dépt. Doubs - France) - 19.06.1993

Please excuse the bad quality of the photos

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.

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

- The tergite 8 is without depression and without longitudinal ridge (See the photo).
- The form of clypeus (See the photo).
- The Abdomen is black and the median tergites have drawings dark red.
- The mesepisternum are entirely black (See the photo).
Thus the capture can be T.stigma or T. excisa.

In addition we note that :

The coxae 3 have a longitudinal white spot (See the photo)

According to Berland p.143, it is about :

Tenthredopsis stigma (Fabricius 1798) ♂ Che vive anche in Italia .
..... OK ?

Saluti.
