E.V. Tsvetkov
Abstract. Homoeosoma oxyargentella sp. nov. is described from the Leningrad Province of Russia. The new species can be distinguished by very short wedge-shaped processes of vinculum, rather narrow valva, relatively long sacculus, and straight or only slightly convex anterior margin of gnathos in male genitalia; and by elongate signa, short eighth tergum, and short posterior apophyses in females. A key to the European species of the genus Homoeosoma Curtis, 1833 is given based on the male genitalia and external characters.
Key words: Leningrad Province, Russia, Pyralidae, Phycitinae, Homoeosoma, new species
