Description and Diagnosis

The main characters are basically the same as in the nominate subspecies described above. Referring mainly to (Fig. 5), P. j. fennoscandica differs in the following ways:

the hypopygium is slightly larger

the apical tooth is narrower and hooked

the gonostyles are more tumid

the intercoxal area is fused and U-shaped

the first palpomere contains 1-3 bristles

the tegmen is broader and shorter with darkened lateral edges

the setigerous papillae are centrally located behind the tegmen when viewing ventrally

Etymology

The subspecies was named after the region Fennoscandia where it has been collected.

Distribution

Boreal zone of Palaearctic Region.

Ecology

The method used to collect specimens of P. j. fennoscandica was non-substrate specific (aspirator and sweep-net). It is therefore difficult to comment on its ecology. As it was found in mixed subalpine forest it appears to be forest associated but any deadwood associations are unconfirmed until more substrate specific sampling is carried out.
