Cranefly - similar to Tipula limbata venation

I visited a local raised-bog NR the other day, hoping (for instance) to find a Prionocera species). I only found one cranefly - here it is.

I adopted the strategy of matching venation first, then checking other factors afterwards, and otherwise making sure it wasn't an obvious species. It has some similarities to T. paludosa and oleracea, but not enough.

It best matches T. limbata, but I couldn't find images to allow me to check the plausibility.
Also T. irrorata is similar, but the male body markings don't look right.
So I'm stumped.

Unfortunately the pictures I took specifically for venation are badly impacted by sun glare, so I'm uploading images which just happen to have the wing in focus. The image with sun glint has also been uploaded.

This is Tipula (Acutipula) vittata.  It is a large striking cranefly of early Spring - often one of the first Tipula of the season to be recorded, in muddy wet woodland, by seeps, springs or streams.

Habitat sounds okay too.

Thanks very much, John.

That species was not in the quite comprehensive list of Tipulidae wings. So it explains why I couldn't find it!
Perhaps not the best method after all.
