Moved from Tipula tricolor.

This must be a male T. fraterna. I've been eyeing this submission for a while. I could never decide whether some things were a figment of the lighting or not, but one of them is the hyaline obliterative streak on the wing possibly reaching from the stigma down to past the base of the discal cell, well into cells M3 and CuA even reaching the hind margin of the wing. Now that I can see the full-sized image, it has become clear. This character is very obviously not in T. tricolor but distinctive for T. fraterna and floridensis. The lack of the pair of long setae on the genitalia confirm it's not T. tricolor. It shouldn't be T. floridensis since it's only recorded in Florida, but the geographic range of Yamatotipula is not to be relied on. I'll move it to subgenus but will hopefully be back to confirm which species it is.
