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. |

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: https://zenodo.or...ds/4417405
While others can't climb, using infinite pains, I, gravity turning to jest, Ascend, with all ease, perpendicular planes, Rough or smooth, just as pleases me best. |
