By its specific habitat it is of course not frequent to see this species, but like it is written, I assume it can be "locally frequent" on the Atlantic coast. I have found 5 females, and 0 male. I have to find the males. And if I can, some
Neolimnophora would be welcome too ! I also found an
Aphrosylus (Dolichopodidae), who attracted my attention by making some flashing white spots on a rock. I didn't know that genus, making signals like
Poecilobothrus, but with its palps ! I must return to the beach tomorrow...

:) But you have at least one Neolimnophora ;) . Maybe you will find other than N. virgo... then let us know.

I would like to see a photo of the habitat, please.
Did you find any Tethina spp. as well?

No Tethina. Here is the habitat :

Merci, Stéphane! Any chance to give the detail of location in google maps??... perhaps that beach is located somewhere here:

It is
here 15 km at north of Le Havre, also known as "Antifer port".
Today I managed to catch three males, well more dynamic than females, always in movement. They touch and go on the sand, never stay more than 1-2 sec in rest. They are darker and slender than females.
Here are two bad pictures :
