Dear Nikita, thank you very much for your quick answer.

I found two more animals in the same Malaise trap sample: one is probably the other sex of the same species already shown (both share the darkened tips of wings; left image). The third animal lacks the darkened wing tips (right image).

The sampling location is Onetahi, Windward Islands - Society Islands, French Polynesia; April 2021.

J.R. Malloch (1937) Muscidae of the Marquesas Islands describes the species Atherigona ustipennis, which has a "distinct brown cloud along the tip of the costa from apex of second to apex of fourth vein". Other characteristics in Mallochs description of A. ustipennis seem also to match the species I collected.

Might the other species, which lacks the darkened wing tips then be Atherigona orientails?

Thanks, Best
Seb
