Another shot.

Anthomyiidae.
There are two cross veins parallel in wing. Not usual, too.

Oh, well observed Jorge !
Seems to be only the right wing. Anomaly ?

Yes. Almost sure. It is a variation that could happen among individuals. Sometimes it becomes conspicuous.
Maybe a mutation in some (or even only one) genes. It is hard to be sure.
As you know we can change some homeotic genes (responsible for information where the organs must appear) in
D. melagonaster so in imago could appear, for example, not one pair of wings but two pair. In the above case, very improbable that
homeotic genes were affected.
See here one example:

Good point Jorge! I would have missed this.
As a geneticist I would also rule out the role of homeotic genes in this case. They have a role in determining body parts, but not the fine patterning of wings.
I think this is clearly a developmental anomaly that probably does not have a genetic background, because the phenomenon can be seen only on one of the wings. Maybe during pupation there were some physical constraints that lead to the anomalous development of one of the wings.

maybe it would interesting to create a new section concerning "anomalies of the flies"?
