Back at home and it turns out it really was Epiphragma (ocellare - the only one), so not only a cracking fly, but a new county record.I checked the distribution of it on NBN this morning. Very weird! A ubiquitous fly in England and Wales and one record per county in Scotland. Clearly recorder distribution at play but a severe case!
A link to some nicer pictures as it was in the field: link
Only two additions:
|625||Tipula lunata||A Cranefly|
|626||Epiphragma ocellare||A Cranefly|
