Hi all,

I really struggle with this one, sample from foredune marram grass NW France.

The frons is pale but from ocellar triangle on dark brownish.

There are 4 pale F-bristles pointing up/slightly back
There is a row of 3 pairs of pale interfrontals pointing forward
The pale Oc-bristles are divergent
The pale P-bristles are rather small (1/2 of Iv) convergent
The pale Iv-bristles are large and convergent
The pale Ov-bristles are idem as IV but divergent

More pics can be made.
Any tips welcome!
Thanks!
