I found this in limestone woodland today. I have never seen it before (or at least I have never noticed it before). I am trying to ID the family with Colyer & Hammond, but meanwhile I thought Diptera.info might like to suggest an identity.

And here's a lateral view - it has big genitalia

After a quick search of images and Colyer & Hammond I think this is a member of the family Platypezidae. Am I correct? Can anyone suggest a genus and advise on how to ID it?

Hi Nigel
Yes it's Platypezidae, and the name that springs to mind is
Lindneromyia dorsalis, a relatively early species (many of the others occur later in the summer and autumn, when fungal fruiting bodies are more in evidence). I don't have the right literature to hand to check this ID, but I know that the regulars on this site won't hesitate to correct me if I'm wrong! ;)
This species is recognisable on wing venation and body colouration (many of the others have grey or orange markings). The flight time is also a guide, as I mentioned before.
Peter Chandler has produced an excellent Fauna Ent. Scand. monograph which is the standard work.

Since you ask I must correct you :D It belongs to
Callomyia speciosa (Platypezidae)

Thanks Kahis and Tony. This one was caught on 10 August, so I guess it is one of the late season fungal specialists.
