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.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol
