Abstract: In the course of a long term survey on the effects of grazing on the diversity of alpine grasslands, the false scorpion Chthonius (Ephippiochthonius) poeninus Mahnert, 1979 was recorded for the first time outside of Switzerland. The preferred habitat at the locality Alpe Einödsberg (Germany, Bavaria) differs strongly from previous findings. Our data suggest an association with Nardus grasslands (Geo montani-Nardetum), whereas earlier records originated from leaf litter, moss and mouldy trunks. Furthermore, the new records between 1540 m and 1973 m above sea level are the first from the subalpine region of the Alps (hitherto C. poeninus was known from 550 m to 1450 m). In the study region, extensive grazing seems to have a positive effect on the abundance of the species, while it is missing from intensively grazed pastures.
