I have taken this ~2 mm fly in southern France, at Les Matelles (near Montpellier) in June 2020. I believe it is Oscinella, but it might be difficult to say from those pictures. Additional features are: eyes bare (or maybe with a few erect hairs), pleura bare, post ocellar seta cruciate, ocellar triangle entirely shining and reaching front margin, rest of front dull, postpronotal lobes shinier than scutum, small seta on scutum aligned longitudinally. I have another specimen looking very much similar but darker (legs entirely black, wings brownish).
