Polia (Polia) bombycina (Hufnagel, 1766) Phalaena bombycina Hufnagel, 1766, Berlinisches Magazin 3 (4): 410. Type-locality: [Germany] vic. of Berlin. Type (s) destroyed. Taxonomic notes. The Asiatic populations of P. bombycina clearly show a western-eastern subdivision with some overlap in Mongolia. The west Asiatic group of populations has two contrasting forms (subspecies?) at the eastern edge of the range, (i) the dark bronze-brownish Polia bombycina puengeleri Lehmann, 1998, described from [Kirghisia] Alexander Mts and occurring also in Kazakhstan, and (ii) the pale fawn-coloured Polia bombycina psammochrea Varga, 1974, described from Mongolia, Govi Altai aimak, Khasaght Khajrhan Mts. The taxonomic subdivision of the eastern group (cf. Polia bombycina grisea (Butler, 1878)) described under some different names (see: VARGA et al. 2017) needs further surveys, as well as the populations occurring in the Caucasus range.
