Introduction

The fauna of Pyraloidea of Omsk region was presented by 66 Pyralidae and 94 Crambidae species (Knyazev 2022). It was firstly revised by Knyazev et al. (2014) and slightly supplemented later (Knyazev et al. 2016; Knyazev et al. 2017; Knyazev et al. 2019; Knyazev and Ponomarev 2019). New materials on rare and little-known taxa were revealed in our collections recently. It turned out that in these collections there are a number of species that have not been previously recorded in the study area.

Materials and methods

All material processed within the framework of this article was collected on the territory of the Omsk region in the period from 2013 to 2022 by S.A. Knyazev, S.M. Saikina, V.V. Rogalev and A.A. Sal`nik at the light of HWL-250 and HSL-250 lamps. Identification of the material was carried out mainly basing on study of the preparations of male and female genitalia using modern keys and taxonomic revisions for individual families or genera. The most part of specimens stored in private collection of S.A. Knyazev (Omsk, Russia), some specimens stored in the Laboratory of Insect Taxonomy of Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia).
