Gnophomyia male - species?

This keys to Gnophomyia with no issues.  It is a male - obviously not elseneri.  I can't see the cleft inner style of viridipennis - also the basal flagellar segment doesn't look elongate enough.  I've no experience of viridipennis, so would welcome any feedback.  It is from an upland wooded clough on moorland edge in the Cumbrian Pennines - taken on 13th June 2017.  There was plenty of dead wood around.

Re: Gnophomyia male - species?

Hi Steve.  This is a nice record, especially because it is a male, and my thoughts are that the genitalia need careful work.  It could be G. lugubris, and we don't have much experience of that here in the UK.  Can you get some good pics ??  I would be happy to do it if not, and if you can get the specimen to me.  Very often, what you see depends on the viewing angle, which can sometimes be difficult to change.

Thanks John.  I'll try better shots first - might soften it a bit and try to get a better angle on the inner style.

Re: Gnophomyia male - species?

I'm now having doubts about Gnophomyia, having found pics online of genitalia - looked again and the wings are wrong.  I keyed it again and it ran through to Limoniid Craneflies with a closed discal cell. - then to key C - Then it gets problematic - actually ended at Erioptera bivittata - which is plainly wrong!
Anyhow - better genitalia pic now there and a pic of the wing.
I'm sure I'm missing something blindingly obvious!
