An annotated list of 50 species of narrow-winged pyralids is provided, including the species, which were ever recorded in Leningrad Province and the city of St. Petersburg. Eleven species are new for the region, among them 6 species which are new for Northwest region of Russia; one species, Ephestia mistralella (Millière, 1874), is reported for Russia for the first time.

Trachypteryx electrica sp. nov. is described from West Kazakhstan. The new species significantly differs from other species of the genus Trachypteryx Ragonot, 1893 in the female genitalia: the ductus bursae is strongly reduced and the diverticulum is absent. Two species of the subgenus Bazaria Ragonot, 1887 of the genus Gymnancyla Zeller, 1848, G. turanica sp. nov. and G. latialata sp. nov., are described from the Kyzylorda Province of Kazakhstan. Christophia constricta sp. nov. is described from the same locality. The male and female genitalia are illustrated for all species described.

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.

Asalebria (Exophora) vernalis sp. n. and Gymnancyla subgilvella sp. n. are described from Atyrau and Mangistau Regions of Kazakhstan. Male and female genitalia of these species are illustrated. Asalebria (Exophora) vernalis sp. n. differs by wing colouration and by genitalia structure from all known Asalebria species. Gymnancyla subgilvella sp. n. can be mixed with two Gymnancyla species, G. gilvella (Ragonot, 1887) and G. nomiella (Ragonot, 1887). The differences from two mentioned species are found in both male and female genitalia and also in venation. Резюме. Asalebria (Exophora) vernalis sp. n. и Gymnancyla subgilvella sp. n. описаны из Атырауской и Мангистауской областей Казахстана. Приводятся иллюстрации гениталий самцов и самок этих видов. Asalebria (Exophora) vernalis sp. n. отличается окраской крыльев и строением гениталий от всех известных видов рода Asalebria. Gymnancyla subgilvella sp. n. может быть спутан с двумя видами рода Gymnancyla, G. gilvella (Ragonot, 1887) и G. nomiella (Ragonot, 1887). Отличия от двух упомянутых видов имеются в строении гениталий самцов и самок, а также в жилковании.
