The crane fly collection and a small amount of unidentified material deposited in the Zoo- logical museum, university of lund, Sweden, was examined by the author. Five species (Elephantomyia krivosheinae Savchenko, 1976, Erioptera nielseni de meijere, 1921, Go- nomyia subtenella Savchenko, 1972, Metalimnobia tenua Savchenko, 1976 and Tipula wahlgreni lackschewitz, 1925) are reported for the first time from Sweden. locality data for these species and nine other species, which are considered rare and poorly known in Sweden, is provided. layer photos of female hypopygium of Tipula wahlgreni and its close relative T. mutila Wahlgren, 1905 are presented.

Since the group of nematoceran insects (de Jong et al. 1980’s, scientific study of Swedish crane flies 2008). a total of 406 species are known from the has been modest. although some crane flies have Nordic countries and 355 from Sweden (Salmela been red-listed (Bartsch et al. 2005, Cederberg et 2010). These fragile and lanky flies have been al. 2010), the listings have almost entirely been studied in Sweden since the era of C. v. linné based on old information and covered only about (e.g. linnaeus 1758). Dozens of crane flies were 30 % of the species present in Sweden. Thus, de- described by J. W. Zetterstedt (e.g. Zetterstedt spite a long tradition of crane fly taxonomy and 1838) and later revised by H.D.J.

Other material was loaned from Zo- ologisches Forschungsmuseum alexander koe- nig, Bonn (ZFmk). If needed, abdominal termi- nalia of the studied specimens were macerated in 10 % kOH solution and finally preserved in microvials in glycerol. Comparative material (female specimens of Tipula wahlgreni and T. mutila) is deposited in the Zoological museum, university of Turku, Finland (ZmuT). If not otherwise mentioned, faunistic records from Finland are based on the author’s data-base of Finnish crane flies. layer photos were taken using an Olympus SZX16 stereomicroscope at- tached to an Olympus E520 digital camera.
