Small sized
Tipula 12.45 mm wing length, 9.5 mm body length, attracted to light, 2016, september the 3rd (Iberia: Catalonia: Girona: Beuda: 400 masl).
* Following the key at Faune de France (Pierre, 1926)
- Ailes presque unicolores, noirâtres, grises, jaunâtres ou roussâtres; bord antérieur parfois un peu plus foncé.
- Ptérostigma plus ou moins visible, précédé ou non d'une lunule blanche assez développée, souvent réduite à une petite tache pâle à peine distincte.
- RI et R2 anormales.
- R2 incomplète n'allant PqS jusqu'au bord de l'aile.
* Following Sttubbs and Kramer (2016)
- Middle flagellar segments with one or more median bristles.
- Wing with R2 short or missing. Definitely not meeting costa, even if the break is short.
- Pleura yellowish, at most with light grey patches.
Could this be
Tipula (Mediotipula)?

In all the drawings of ovipositors by Theowald 1978, the cerci is driven forewards, so it's not worth comparing cerci/valval lengths but reading the text instead:
If we easily assume
Mediotipula subgenus, then:
Thorax matt with four more or less distinct stripes
Cerci equidistant over a greater part of its length and with a clearly rounded tip.
The first three flagellar members each clearly shorter than the first antenna member.
Hypovalve base not thickened
Praescutum yellowish brown frosted with brown longitudinal stripes:
drives to
Tipula (Mediotipula) siebkei
Wing length 12.45 mm and fly period vii-ix is also concordant.
