Mycetophilidae: Sciophila?

Hello

This fly, which I believe is a Mycetophilid, was swept from vegetation today in wet woodland in Surrey. I believe it to be a Sciophila or at least of the subfamily Sciophilinae due to the presence of the rectangular cell near the top of the wing (sorry I don't know what it's called).

Any help on getting any further would be much appreciated, I'm not sure which parts are needed for ID so if you let me know then I can photograph them.

Thanks a lot

James

I think this is Mycomya sp. A female, if I'm not mistaken.

Thanks John. Do you know if there is any literature for the genus? Although I'm assuming most of it will be based of the male genitalia.

The RES Handbook only keys males and, you're right, the they are best determined with reference to the male genitalia. But you could say that
about most fungus-gnats.

Thanks John. I'll keep my eyes open for males then.

As the front metatarsus is distinctly longer than the tibia, I would say it is M. cinerascens.

Thanks Peter, I wasn't expecting a specific ID!
