Fortunately, the "sex combs" on the two basal joints of fore tarsi are (barely) visible. Drosophila obscura group.

Thank you very much! I will try to keep the legs more in focus.

Are the species of Drosophila obscura group (believe "D. obscura/subobscura" in NL) distinguishable without genital dissection?

Principally yes, just the photos (of forelegs, palpi, abdominal end...) should be much better. I believe that more species occur in NL (ambigua, tristis...).

Noted, will keep this in mind for the next pictures (if I even succeed). You are right about the other species. Thank you!
