Original data on Dolichopodidae from the Belomorsk district of Karelia and Bolshoi Solovetskii Island (Arkhangelsk Region, Primorskii district) resulted from the short-term visit (2018) are presented. All ten collected species and the genus Medetera are firstly recorded for the Solovetskiye Islands. Dolichopus discifer Stannius, 1831, Dolichopus ungulatus (Linnaeus, 1758), Rhaphium laticorne (Fallen, 1823), Sympycnus pulicarius (Fallen) and Syntormon tarsatus (Fallen, 1823) are new species for the Arkhangelsk Region. Photographs of habitats of dolichopodid species are included. Key words: Diptera; Dolichopodidae; Palearctic Region; Arkhangelsk Region, Russian Karelia; new record; fauna

Introduction

The former Arkhangelsk Governorate (Russian: Архангельская губерния, Arkhangelskaya guberniya), later Northern Krai (Russian: Северный край, Severnyi Krai) occupied in the 19th and the first half of 20th century a huge territory along the Arctic Ocean between Finland and North Ural, being currently divided between the Republic of Karelia, Murmansk, Arkhangelsk, Vologda, Kostroma, and Kirov Regions, the Nenets Autonomous Okrug, and the Komi Republic, with the informal name Russian North (Gundakova et al., 1997). The White Sea is an indentation in the coast of Russian North, and surrounded by four regions, i.e. Murmansk and Arkhangelsk Regions, Karelia and Nenetsia. It is 590 km long and has an area of 90,000 sq km. Major embayments include the Gulf of Mezen (Mezenskaya Guba) on the east, Dvina Bay (Dvinskaya Guba) on the southeast, Onega Bay (Onezhskaya Guba) on the south, and Kandalaksha Gulf (Kandalakshskii Zaliv) on the northwest. At the entrance to Onega Bay are the Solovetskiye Islands including the largest in the area Bolshoi Solovetskii Island. The White Sea has also hundreds of small islands along its western coast mainly.

The area northward of 64° latitude is studied rather spotty in case of the long-legged flies. The list of the Karelian Republic contains now 132 species (Grichanov et al., 2017) with several species found at the White Sea coast of Karelia and on small Karelian islands along this coast (Humala, Polevoi, 1999, 2008, 2015; Grichanov, Polevoi, 2004). The list of Murmansk Region includes 92 species of long-legged flies (Grichanov, 2006), nevertheless, more than 50 species have been collected from environs of Kandalaksha at the head of Kandalaksha Gulf of the White Sea (Frey, 1915; Negrobov, 1974), and the other species are found in the Pechenga and Ponoy districts, with Hydrophorus ponojensis Frey, 1915, endemic of the Kola Peninsula and found at the mouth of White Sea. The fauna of Arkhangelsk Region is mainly studied by Frey (1918) and Pryakhina, Ogibin (1970). Stackelberg (1962) included the Solovetskiye Islands into the area of Dolichopus maculipennis Zetterstedt, 1843. Grichanov (2006) mentioned 41 species for the Arkhangelsk Region. Ten species have been reported from Nenetsia (Grichanov, 2006), including Hydrophorus signifer Coquillett, 1899 from the Kolguyev Island and Hydrophorus alpinus Wahlberg, 1844 from the Dolgii Island, Campsicnemus armatus (Zetterstedt, 1849), Dolichopus plumipes (Scopoli, 1763), D. rupestris Haliday, 1833, H. alpinus and H. signifer from the Kanin Peninsula enclosing the White Sea from the North-East.

The material for this study (156 specimens) has been collected by authors during a 2018 expedition to the Solovetskiye Islands through the Karelian Belomorskii district by standard sweep net. The main collection sites are located at the Karelian White Sea port Belomorsk and on the Bolshoi Solovetskii Island at the Solovetskoye settlement (Arkhangelsk Region). None dolichopodid fly was found on the Bolshoi Zayatskii Island at the southern end of the main Island. This paper presents the new species records in detail. Records of 12 species listed below are arranged

alphabetically by genus. Information on the world distribution for each species listed follows Grichanov (2017). The type localities are provided and the country lists are arranged alphabetically. Material of the newly-recorded species will be deposited at the Zoological Institute of the Russian Academy of Sciences, St. Petersburg, and the Zoological Museum of Moscow State University, Moscow, Russia. Specimens are mounted on pins and placed in the museum drawers. Photographs of common habitats of dolichopodid species are provided below (Figs. 1 -4).

Conclusion

Only one species (Dolichopus maculipennis) was known from the Solovetskiye Islands before our short-term visit there (Stackelberg, 1962). The weather during our stay was warm and almost dry, the same as for the whole month before our visit. Rivulets and marshes had practically no water except for narrow bands along lake shores. That was probably a reason of collection of only ten dolichopodid species. All these species and the genus Medetera are new for the Islands. It means that possible faunal composition of the family must be many times more diverse there. All the collected species are widespread across the Palaearctic Region or even across the Holarctic Realm; nevertheless, Dolichopus discifer,

D. ungulatus, Rhaphium laticorne, Sympycnus pulicarius and Syntormon tarsatus are new species for the Arkhangelsk Region. According to sampling data, two species (Campsicnemus scambus and Sympycnus pulicarius) have the highest total abundance in both Belomorsk district of Karelia and Bolshoi Solovetskii Island. It is worth noting that Dolichopus maculipennis and Rhaphium laticorne are unknown in the neighboring Karelia, and Campsicnemus armatus and Hydrophorus signifer are not found in the well-studied Leningrad Region (with about 230 species in its fauna). The Dolichopodidae of the Arkhangelsk Region fauna contains now 47 species, and the Solovetskiye Islands fauna includes 11 species.
