I took pictures of this mycetophila on 9th of January 2022 in Den Helder, Noord-Holland, Netherlands on a graveyard. Its winglength is about 3,8 mm.

Can someone tell which species of mycetophila is this? Maybe 'attonsa'?

Thanks a lot.

Greetings,
Mario Renden

Mycetophila curviseta. Two strong curved spine-like bristles on outer surface of ventral lobe of gonostylus are clearly visible. From the original description (Lundström, 1911 Ann. Mus. Nat. Hung., 9: 411): "Die grosse Unterzange ist auf der oberen Seite mit zwei halbzirkelförmig gebogenen, grossen Borsten versehen".
