Eupeodes biciki spec.noY. is described from Floyfjell, Tromso, northern Norway. The species is figured

The European species of genus Eupeodes Osten
Sacken (previously Metasyrphus Matsumura) has
recently been revised by Mazanek & al. (1998,
1999 a,b,c), including also a critical study ofthe
Norwegian fauna, with a key to the twelve species.
The new species, described here, is a result from
this revision.
METHODS
Measurements were made by using ocular
micrometer in aCarI Zeiss Jena Citoval 2 microscope.
The width of face was measured at midpoint
between antennae and facial tubercle. The
length and width of clypeus were measured in
middle lines. The length of the third antennal
segment was measured on the inner side, from its
apex to the mid-apex ofthe second antennal segment.
The male terminalia were figured by using
a demonstration tube on a Carl Zeiss Jena Laboval
3 microscope.
