Taxonomic notes.

Based on the type catalogue of the Lepidoptera collection of ZISP it became evident that Hadena subcontigua Eversmann represent the same species as Hadena altaica Lederer and at the same time also its westernmost occurrence. This species exist in most localities from the Tien-Shan Mts. to Central Mongolia and also Nepal in polymorphic, contrasting vs. concolorous forms. Therefore, Mamestra monotona Bang-Haas cannot be considered as own taxon. According to the description and photos, the taxon Polia (Mamestra) praecontigua Turati, 1933 also represents this species. The occurrence of P. subcontigua in the Karakoram and the Western Himalayan mountains was confirmed by the recent surveys, too.
