Hello,
Could this be a
Rachispoda sp. ??
I think it is a Sphaeroceridae due to the long arista and the short and enlarged first segment of the posterior tarsa.
Then the wing venation looks like a Limosininae to me.
If right up to there, then it should be either
Leptocera or
Rachispoda…
And I think I see two or four antero-dorso-central setae curved toward the middle in the front pictures, which would be the criteria for the latter, isn’t it ?
If necessary I’ve got other pictures, maybe to come to the species… (it is not forbidden to fantasize…).
So thank you very much for your help; and if anybody can come to any kind of ID, it would be wonderful to specify which criteria on the pictures lead to this conclusion!
Thank you anyway!
