Heliosperma arcanum Zapal. , Rozpr. Wydz. Mat.-Przyr. Polsk. Akad. Um. (Biol.) ser. 3, 11 B: 267 (1911) is, according to Neumayer, conspecific; it was described from a single gathering from a gorge of the D nestr river, W. Ukraine, but there is no recent confirmation of this record. An old record of S. alpestris from the Polish Carpathians also cannot be verified.
