This species is endemic to Austria. It has a relatively large distribution and the main threat is not thought to impact all the sub-populations. It is therefore assessed as Least Concern (LC). However, some subspecies have extremely restricted distributions and all subspecies, except Orcula austriaca austriaca, are considered threatened and are red-listed in Austria.
|Previously published Red List assessments:|
