Thread subject: Diptera.info :: Spilogona?

Hi everyone,

I'm a bit lost with this specimen found in my garden 2 days ago in north France.
Using D'assis Fonseca i find Spilogona genus (Radio cubital node totally bare) but using the same key, it is a dead end:
- Arista hairing is really big, but there is no ad on middle tibia...
I looked at S dispar, but there is no ventral bristle on tibia 2.
So am I wrong on the genus, or is it a specie that isn't in this key? (Recorded from Belgium there is Spilogona carbonella for which i couldn't any information, and S falleni, that could be a synonym of S litorea Fallen?)

Clovis, you should try again your key with Hebecnema.

Aie! It fits much better!!!!! i end out directly on H vespertina (=[H affinis Malloch for what i understood) based on the 2 av on Tibia3+ haltères yellow.
And is H vespertina in D'Assis Fonsseca= H nigra? I'm not sure

Many thanks for you help Stéphane, i was totally lost!!! :D
