Hello, may be you can answer this question at least about the family. Tephritidae or not
Unfortunately I am not an expert.
It's a small fly (body is about 5 mm). French Guiana (neotropical).
Thanks.

Many thanks John. For sure it is a very strange Dolichopodidae, especially the wings pattern !
May be it is possible to identify more acutely ? A tribe or something....

The wing pattern is unusual for Dolichopodidae. Most markings are simpler, with dark bands or white spots on the wingtip. The oddest wing I have seen in the family belongs to the Brazilian genus
Mberu.

My first guess is
Paraclius or
Pelastoneurus, based on the angled M vein and strongly bristled legs.

Checking a book I see there are other neotropical genera in this group, including
Stenopygium which has marked wings.

I think this fly strongly resembles (if not identical with)
Stenopygium punctipennis (Say, 1829), originally described from Mexico, also recorded from Bolivia, Costa Rica, Guatemala, Panama and Venezuela. Cf. Soares & Ale-Rocha, 2020 (New records of
Stenopygium Becker (Diptera: Dolichopodidae) from the Neotropical Region, and a key to species - Zootaxa 4868 (1): 129-134), figures here:
