Thanks Tony but I don't know any Drosophilidae without subcostal cell ?

Apparently there is a malformation of the wing base in this specimen. Among others, anal vein is absent.. Otherwise, it is a typical female of D. obscura group, probably D. subobscura.

Thanks Jan, I didn't imagine such a deformity.

Wing slightly darkekened along costal margin, a single strong apical seta on the palp: D. (S.) subobscura
