Two new species of <I>Swammerdamia</I> from the southern Ural Mountains and southern Siberia (Lepidoptera: Yponomeutidae)

Swammerdamia glaucella sp. n. and S. buraetella sp. n. are described on the basis of material collected from the southern Ural Mountains and southern Siberia. S. glaucella occurs in forest steppe slopes and bushy meadows in two generations from the end of May to the beginning of July and late July. The species is widely distributed in southern Russia and the adjacent regions. S. buraetella is only known from Buryatia where it seems to favour open steppe habitats. The species occurs in two generations from the end of April to the end of May and in July. Both new taxa differ from their known relatives both externally and on the structures of genitalia. The Russian records of Kessleria caflischiella (Frey, 1880) are discussed.
