At least visually, Ectophasia crassipennis comes close. It may not seem a 100% match yet if you check many photos, you'll notice they are quite variable. Example:

  Yes, it is close, I have checked too many photos and think this one at Inaturalist is not E.crassipennis. E.crassipennis has a different wing pattern with few black spots.

    Very tricky discussion. Have a look here for many examples matching your photo:

    It could be true that they're all misidentified. Yet it concerns a significant amount of individual photographers, so in that case the error would be widespread. Which is of course possible.
    
    It could also be that the spots in some individuals are simply faint. As a result of variability, age, sex, local adaptation, etc.
    
    I honestly don't know which of the 2 statements is true, just offering food for thought. It seems a poorly described genus. Even Bold Systems is lacking, which is rare.
    
    Best of luck ;) Posted 3 months ago, modified 3 months ago

      Hm, I think you are right. The wing pattern is a kind of sexual diformism! The females have the same pattern like on my photo. I shall identify it as Ectophasia crassipennis, but in the title shall put Ectophasia cf. crassipennis. Posted 3 months ago
