Locally common. There are many records (most
of which arc given as Glomeris connexa, which in some regions
makes it difficult to be sure which species is implicated/ From
some areas the data are dubious and appear to be outside its
range. However, Verhoeff considered it to be a glacial relict,
at least in the west of its range; he supposed that it had a
larger distribution in former colder times. Isolated popula
tions do occur. It was reported from a cave in Belgium by
Schubart (1935), as G. connexa, and later from a hole and two
above-ground sites by Dc Queker (1962) also as G. connexa.
It has not been found in Belgium during the last 40 years.
Because of confusion with G. connexa records from
Italy are doubtful, it could occur in the Alps in the extreme
north as it occurs in the Austrian Tyrol. In France it is
limited to the Jura and the Alps, from where it extends
eastwards through Central Europe all the way to Russia,
although it is quite possible that in the eastern part of
the range tetrasticha is replaced by another taxon (Hoess
& Scholl, 2001). In this case our habitat data from Poland
and Belarus would not apply here. I loess & Scholl (2001)
provide a map of its supposed distribution based on
enzyme studies and other criteria.
