Numerous specimens from Tuva (
Marusik et al. 2000
), North-East Siberia (
Marusik et al. 1992
), Yakutia (
Marusik et al. 1993
), Greenland (
Marusik et al. 2006
) have also been examined.
Comments.
It has not been possible to trace the Finnish specimens used for making the figures of
Dictyna schmidti
in
Almquist (2006)
. The illustrations are probably based on misidentified specimens and seem to refer to
Dictyna major
.
Description.
Thoroughly described by
Wiehle (1953)
, Chamberlin & Gertsch (1958) and
Almquist (2006)
. Here we provide only comparative figures of the copulatory organs in order to demonstrate differences between it and the similar-looking
Dictyna palmgreni
sp. n. and
Dictyna schmidti
.
Distribution.
The species has a circum-Holarctic range and is known across the Palaearctic and Nearctic Regions.
Natural history.
This species has different habitat preferences in Siberia and in Finland. In Magadan Area, it is the most common dictynid species, occurring in various
habitats
within the forest belt and is most numerous on
Ledum
shrubs. In Finland,
Dictyna major
is rare, has a scattered distribution and occurs exclusively on dune shores.
