I saw a beautiful Phoridae today in Biezenmortel, the Netherlands. It had very long bristles on the costa. Any ideas?

Hello Niels-Jan, I don't know much about Phoridae but found drawings of wings in Disney (1989): Scuttle flies, Genus Megaselia. The wing of M. hortensis looks very similar to those of your fly.
Greetings, Eric Kloeckner

Thanks Eric. I see now there are more species in Megaselia with these kind of bristles so for now, I will keep it as cf. Megaselia spec.

You might compare the tip of the abdomen with one of the Phalacrotophora species... https://diptera.info/downloads.php?cat_id=7&download_id=6

I checked the key to the Phoridae genera in Disney (1983), Handbooks for the Identification of British Insects. I am unfamiliar with Phoridae, but I think I arrive at Megaselia.

I do not see an anterodorsal row of bristle-like hairs.

The tergites seems to be normal, although a bit damaged?

The abdominal tip in lateral view is like this and I do not see much resemblance in Phalacrotophora.

Do you agree with Megaselia?
