Introduction

In the last two decades, the authors have been actively researching the Lepidoptera fauna in the south of Western Siberia. In 2023, the first author made expeditions to the northern regions of Omsk region, as well as to the south near the border with Kazakhstan. The second author made several expedition trips to the steppe territories in the south-west of Novosibirsk region in 2022-2023. Extensive collection materials were collected, including species not previously recorded in the studied regions. These materials became the basis of this article.

Materials and methods

All materials processed within the framework of this article was collected on the territory of Omsk and Novosibirsk Regions mainly in 2022-2023 by authors using standard methods by butterfly net and by using mercury lamps 250W. The identification of the material was carried out using modern keys and taxonomic revisions. All specimens deposited in collections of Svyatoslav Knyazev (SKO, Omsk, Russia) and Vadim Ivonin (VIN, Novosibirsk, Russia). A list of species made in accordance with the system of the Catalog of Lepidoptera of Russia (Sinev 2019).
