Ciao,

# 2986 captured at an altitude of 940 m. in Cne : Le-Petit-Abergement (Dépt. Ain - France) - 05.06.1995

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 has 2 great central depressions not very deep and hairy , with centrally a longitudinal ridge little visible.
(It was impossible to me to make a correct photo !)
- The clypeus is regularly emarginated (See the photo).
- Metepisternum and Mesepisternum are mainly yellowish (See the photo).
- The femurs 3 are two-tone, the tibiae 3 are brown, and the tarsi 3 have, at least, their tarsomeres median white.

Finally :
Tenthredopsis sordida (Klug 1817) ♂ Che vive anche in Italia .
..... OK ?

Saluti.
