This is clearly Trichocera annulata, no doubts - Jan Willem is right ;) And it is one of the most widely distributed winter gnat species in the world, known from Europe, Northern America, even Algeria and Ethiopia, Australia and New Zealand.
Records from France are rather scarce in published literature (or at leas I haven't seen more of them), mostly from the XIX century by Macquart, 1834; Perris, 1847; some later like Keilin, 1912.
