Tipula grandis Panzer, 1804 (p. 187) (nomen dubium, tentative synonym, see note below)
Tipula irrorata Macquart, 1826
Tipula pictipennis Staeger, 1840
Tipula micans Zetterstedt, 1851

Note: The taxon Tipula grandis has been described by Panzer (1804) from Regensburg (Bayern), but with insufficient detail to identify the species beyond reasonable doubt. In addition the type material appears to be lost. Thus, Tipula grandis is generally regarded as a nomen dubium that will never be identified unequivocally and I agree with this notion. However, I believe that the taxon can nevertheless be tentatively assigned to Tipula irrorata, because the short description and Schaeffer´s figure (Schaeffer 1766) (which was the basis for Panzer´s description) fit quite well with the appearance of Tipula irrorata. Especially the description: "alis nebulosis punctis maculisque costalibus nigris" ("wings cloudy with black costal dots and markings"), fits the wings of Tipula irrorata very well. There are some other Tipula species with spotted wings, but the pattern shown for Tipula grandis fits well with a dark specimen of Tipula irrorata; in addition, most of these other species have further markings on the abdomen (usually a black or dark brown lines), and the figure of Tipula grandis shows a female specimen without dark markings on the abdomen, very similar to Tipula irrorata.
