Fly about 2 mm caught at riverine wateredge area 8 june 2021 mid Netherlands
Looks at first sight like a nice metallic green shiny Chrysotus but different antenne and sturdy white seta on abdomen, scutum etc,
No sub apical anterior seta on hind femur, hind coxa 2 outer bristles top one large at middle lower one smaller.
Antene flagellomere small tubilar roundish (hairy?) second lid about same diameter round and first lid slightly smaller diameter but less thick
Palps blackish,
front, face and clypeus lighly dusted shiny green. Clypeus quite long and rather receding
halterknob yellow and stalk dark color
Front coxa all white hairs and bristles. apical bristles sturdy
AC 2 rows Scutum prescutellar depression
My rough guess is Cyrturella albosetosa female but i have no detailed description of this species.

Thank you Igor to solve the puzzle.

The two outer bristles on coxa of hindleg are very diagnostic I understand.

Looking further into this I come to Thrypticus tarsalis (female).

In the meantime I have also learned that this could not have been a Cyrturella as this is only a tiny fly of 1 mm.
