Can anyone help with an I.D. on this please?

I believe it is genus Chrysops, but would like, if possible, to take it down to species level.

Photo was taken on the edge of woodland in a peat extraction area in South Yorkshire.

Any help (or a correction to my own i.d.) would be appreciated.

Thanks folks!

So that I can learn for the future, can anyone detail the pertinent features that were used for ascertaining the species?

Thanks

This species is often called the twin lobed deerfly, at the top of the abdomen are two black markings (lobes), this added with the wing detail differenciate it from other Chrysops.
