Orange and black Nematinae ID / Brittany / France

Hello,
My first post on HymIS ;-)
What do you think about this orange and black sawfly ? Do you agree with Nematinae Nematus sp. (or even N. myosotidis) ?

Hello,
According to me, it is necessary (at least) that Wings are opened for a beginning of identification !

Hello D & JP,
When opening the link 1 and 2, with "Ctrl+" (or "cmd+") you can see some more details of the nervation (R1 not divided, basal cell divided Sc1...). Thanks for your opinion ;-)

Hello,
We do not see clearly the shape of the small Veins of the base of the Forewings.
See in Benson (http://www.royensoc.co.uk/sites/default ... art02c.pdf) the complex shape of these Veins, essential to determine Tribes or Genera.
Regards.
