Abstract: The article gives a faunal list of Pterophoridae species of Khakassia Republic and the south of Krasnoyarsk region. We have examined 41 localities, as a result of which, 24 species are reported for this region for the first time. In total, 40 Pterophoridae species are currently known for the Republic of Khakassia and for the south of Krasnoyarsk region.

Keywords: Insecta, Lepidoptera, Pterophoridae, biodiversity, fauna, new data, south of the Krasnoyarsk region, Khakassia, Russia.

### Introduction

Khakassia and the south of Krasnoyarsk region are limited from the west by the mountain ranges of the Kuznetsky Alatau and the Abakan Ridge. In the south, the main ridge of the West Sayans is the border line with the Republic of Tuva, and in the north, the East Sayan foothills enter the region from the southeast to the northwest. The height of these mountain ranges reaches 2500-3000 a.s.l. in some parts. The mountain territories of the region are mainly represented by forests, taiga, and high-mountain tundra. The Minusinsk lowland territory is represented by steppe and forest-steppe landscapes. Such a diverse combination of natural zones within the study area allowed us to count on interesting findings of Pterophoridae that met our expectations.

The first data on the Pterophoridae fauna of the Republic of Khakassia were published in 2018 (Ustjuzhanin & Kovtunovich, 2018). Then this list included only 17 species, which was due to the lack of specimens and absence of special studies on the territory of Khakassia. In recent years, the study of species composition of Heterocera in the Khakassia and the south of the Krasnoyarsk region has received a new impetus (Maksimov et al. 2019; Lostchev & Maksimov, 2021; Maksimov et al. 2022). Due to more extensive and systematic research conducted in the region, the entomological material collected over several years made it possible to identify more than 200 species of Heterocera previously not noted in this region. The current study has significantly enlarged the species composition of Khakassian Pterophoridae due to the special research and collection of Pterophoridae specimens by Roman Maksimov, the second author of this article. Besides that, the research area has been expanded in accordance with its allocation in Catalogue of the Lepidoptera of Russia (Sinev, 2019) (Figures 1, 2). As a result, during the last five years 32 species have been revealed, 24 of which proved to be new for Khakassia and the south of the Krasnoyarsk region. In general, considering the known data (Ustjuzhanin & Kovtunovich, 2018), at present the Pterophoridae fauna of Khakassia counts for 40 species.

### Material and methods

All the specimens used in our work were taken from private collections during the period from 2015 to 2022. All the current collection specimens were gathered by us on the territory of Khakassia and south of Krasnoyarsk region in 41 localities with different habitat characteristics, from the steppe zone to the alpine area of the West Sayan, and the Kuznetsky Alatau. Several specimens were caught in the daylight by standard methods, with butterfly net. Most of them were caught at nighttime on the light screen. All the specimens are preserved and stored in private collections of Roman. E. Maksimov in Abakan and Petr Ya. Ustjuzhanin in Novosibirsk.

31. Calyciphora albodactyla (Fabricius, 1794)

    Material: Verh-Bidja 2, 1 ♂, 20-VII-2022; Bolshoe Dikoye, 1 ♂, 29-VII-2022.

    Distribution. Europe, Southern Siberia: Irkutsk, Kemerovo regions, Khakassia. New species for the Republic of Khakassia.

    Note: The first indication for Siberia (Irkutsk) was published (Arenberger, 1995) as a synonym of Calyciphora xerodactyla (Zeller, 1841). Later (Ustjuzhanin, 1996) mistakenly identified as Calyciphora nephelodactyla (Eversmann, 1844), indicated for Taishet (Irkutsk Region). In another paper by the author (Ustjuzhanin, 2001), this species as Calyciphora xerodactyla is recorded for the vicinity of Kuzedeevo village, Kemerovo Region, found in a relict linden grove.

### Conclusion

The southern Siberia is rich in the diversity of natural landscapes and abundance of flora and fauna. Concerning the Pterophoridae fauna, the most studied is Altai, from where 54 species are known (Ustjuzhanin & Kovtunovich, 2007; Huemer et al. 2016; Nupponen, 2022), 37 species are known from Tyva (Ustjuzhanin et al. 2017) and 45 from Buryatia (Ustjuzhanin & Kovtunovich, 2007b). The territory of Khakassia and south of Krasnoyarsk region are profitably located between the western and eastern portions of southern Siberia. From one hand, the west-Palaearctic species penetrate there: Paraplatyptilia metzneri, Oidaematophorus constanti, Calyciphora albodactyla, from the other hand - east-Palaearctic species: Paraplatyptilia terminalis, Gillmeria stenoptiloides, Gypsochares kyraensis, Hellinsia innocens. At the same time, in Khakasia there are its own typical central-Asian species: Procapperia kuldschaensis, Stenoptilia lasani, Stenoptilia latistriga. All this determines the picture of biodiversity of the Lepidoptera fauna, in particular, Pterophoridae, of Khakassia and south of Krasnoyarsk region, which allows to suggest a further increase in the plume moths species composition during the next study for at least 10 species.
