Polia (Polia) vespertilio (Draudt, 1934) Aplecta vespertilio Draudt, 1934, in A. Seitz, Die Gross-Schmetterlinge der Erde 3: 109, pl. 14, row i. Type-locality: [Russia], Irkutsk, Tunkinski Mt. Lectotype: male, in coll. MNB. Taxonomic notes. According to the external look and the configuration of the genitalia of both sexes it can be considered as closely related to the former one.Their distribution is partly overlapping in the southern Siberian and northern Mongolian mountains; however it is more widely distributed both in West (southern Ural Mts) and East (Pacific mountains). Taxonomic interpretation of the Pacific (North Korean) population still requires further studies.
