It has some similarity with
T variipennis to me, but a zoom of the nervation in the stigma area and of the antennas could be good arguments to prove this fealing ;)

Thank you for helping me on this one.
I made a couple of full size crops of the details you asked for.
Unfortunately, due to dark conditions in the forest, I had to go for rather high ISO, so the pictures are not too good.

Well, I think this is T. (P.) varipennis. Note the short and stout legs and short wings (do not extend beyond tip of abdomen).

Well, the habitus make me really think about T varipennis, but in my doc one of the first characteristic it has in the key is a incomplete R2, witch does not extend to the costal (look
here)

Thanks, both of you, for the effort on trying to identify this Tipula.

Stubb writes (Test key for Tipula, p 13): "In some species (pseudovariipennis, submarmorata and varipennis) vein R2 is usually incomplete, not reaching the wing margin, but examples with this vein complete make the character unreliable."
Thus, I think this specimen is varipennis.
Best wishes, Jukka

And finally; Thanks again for all the help on this crane fly.
Nice to get it named, at last.

This is indeed the female of Tipula (Pterelachisus) varipennis Meigen, 1818.
Attached is the photo of the male.
See http://ip30.eti.uva.nl/ccw/ for more details on this species.
