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.
