NUPPONEN & al. (2000: 10): “Lat. aegra = difficult. The name refers to the history of the discovery of the species. We were searching for a sand dune region in Novoiletzk in the evening. While driving along a steppe, the habitat suddenly changed to a wetland and our car partly sunk into a soft ground. We were forced to wait there one day for help. Despite difficulties, we quickly jumped out from the car for collecting, and later found the first specimen of S. aegrella among the material.”
Die Art wurde aus dem südlichen Ural-Gebirge beschrieben.
