Thread subject: Diptera.info :: Which Nematocera family? --> Cecidomyiidae: Lestremiinae, cf. Anarete

Hi, I found this tiny fly (about 1 mm) drowned in an abandoned pool in an oak forest environment. Even the pics are not very well, the antennal fist articles are round like Phoridae, the others verticillate like Chironomidae, the wing venation is like Scatopsidar-Lestremiinae, but no idea what could it be (Iberian peninsula: Catalogne: Girona province: Beuda / 2015: 08: 25 / 400 masl)

An interpretation of wing venation (may be uncorrect)

Even I can not see if there are ocelli or not, Mycomyia (Cecidomyiidae) has the same kind of antenna (as drawn in Manual of Nearctic Diptera) so Cecidomyiidae can be a good clue.

Maybe an Anarete.

Thanks John. I was just going to suggest that genus. Studying the Manual of Nearctic Diptera, I arrived to that genus (despite there are some european genus i do not know which tribe they are). The decreasing size of the floagellomeres is quite characteristic. May interpretation of wing venation was wrong. Here is one more correct.

An enlarged pedicel is associated with male swarming, but is also present to a lesser degree in females of swarming species. In Lestremiinae the swarming genera are Anarete and Conarete.
