This keyed to Asteiidae, and from there to Leiomyza scathophagina, but I don't think I am correct. It doesn't look much like the Asteiidae in the gallery, has too many dorsocentrals and the costa ends too soon for Asteiidae according to Colyer & Hammond. Any suggestions, please?
Wing length 1.5 mm. It emerged a few days ago from an old bird nest collected in a North Wales oakwood last October.

Thanks very much. I have a Meoneura key, but I think it relies largely on male genitalia so I probably won't get very far. Maybe some males will emerge from the nest.

Another female and a male emerged yesterday and the male is M. neottiophila. The terminalia are a good match to the drawing in Collin's 1930 Entomologists' Monthly Magazine key.
I originally got to the wrong family because the AIDGAP key by Unwin says vein 4 does not reach the wing margin, whereas there is a very faint vein going all the way, visible in the first photo. Perhaps if it is as faint as that, it is not counted as a vein.

Another picture of the genitalia, without the pin so not so extruded.
