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.

Introduction from northern Sweden (e.g. mendl 1974, 1979)
In terms of their body size and habitat asso- and from the Baltic coast (mendl 1987), trapped

studied in Sweden since the era of C. v. linné based on old information and covered only about

Material and methods
most of the studied specimens are deposited in
the Zoological museum, university of lund
(Zmlu). 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
