The extremely high diversity of Collembola in relict forests of Primorskii Krai of Russia

The diversity of soil animals of relict forest ecosystems in East Asia continues to be insufficiently studied and almost not represented in international databases, including GBIF. This article is based on 7550 records of 175 species which were collected in Ussuriiskii, Sikhote-Alinskii and Kedrovaya Pad’ natural reserves of Russian Far East in 2016–2017. A multi-scale sampling design allowed us to estimate population densities and local species richness of Collembola at areas of different sizes. The work continues the digitization of the collections of the Moscow Pedagogical State University (MPSU) and their publication through GBIF.org, which began in 2019. This article is based on original data including 2377 specimens of springtails from eight forests and 648 soil cores. Within the framework of modern taxonomy, this work represents the first publication of lists of Collembola species of forests of Primorsky Krai. The work focused on the relict protected cedar-deciduous forests. Nine species new to science were described and data on the fauna of the region were significantly revised. Considerable contribution was made to the biogeography of Collembola of East Asia. The design of the sampling allowed us to draw conclusions about the species saturation of springtails at various spatial scales within the habitat: from a few square cm to 100 sq. m. Number of species reached record high values reflecting the benchmark state of Collembola communities of undisturbed old temperate forest ecosystems.

New algae species records (Chlorophyta, Cryptophyta, Ochrophyta) for the southern regions of West-Siberian Plain and Far East

The new records of genera and species of algae (Chlorodendrophyceae, Chlorophyceae, Cryptophyceae,Mesostigmatophyceae, Raphidophyceae, Xanthophyceae) for the West-Siberian Plain and the Far East, including AltaiKrai, Novosibirsk Oblast and Primorskii Krai, were revealed. All species listed are new ones for the regions, 3 genera and14 species are new for West-Siberian Plain and the Far East, including 1 genus new for Siberia and 1 genus new for the FarEast. The localities and regional distribution are reported for each species.

DYNAMICS OF THE DISTRIBUTION OF THE MOLIPTERYX FULIGINOSA (UHLER) (HETEROPTERA, COREIDAE) IN THE FAR EAST OF RUSSIA

The data of more than thirty years of observations of the temporal and spatial distribution of Molipteryx fuliginosa (Uhler, 1860) (Heteroptera, Coreidae) in the east of Russia are generalized. Previously known only from Southeast Asia, in 1998 it was recorded in Russia as new to the fauna. Its current range in the south of the Far East has been clarified, 51 localities of finding have been noted. The introduction of the bug into the local fauna was traced over the years, in connection with the penetration of which there is a danger of the appearance of a new pest of cultivated Rosaceae in the Primorskii Krai and in the south of the Khabarovsk territories. Three stages of the species penetration into the fauna of the south of the Russian Far East have been identified. In 1987-1992 - rare single finds of a species new to the local fauna, 1993-2011 - expansion of the bug's range while maintaining a low number, 2012-2020 - local outbreaks of numbers along with the expansion of the range in our territory.

Review of the genus Anaphes Haliday, 1833 (Hymenoptera: Mymaridae) in Russia, part 1: subgenus Anaphes s. str.

Species of the nominotypical subgenus of Anaphes Haliday, 1833 (Hymenoptera: Mymaridae) in Russia are reviewed. A key to females of the 18 Palaearctic species of the subgenus is given. Ten species are newly recorded from Russia (two of them based on tentative identifications), and new records of the extralimital specimens examined are also provided. Three new species are described from the eastern Palaearctic region: Anaphes (Anaphes) csabai sp. n. (Kuril Islands), Anaphes (Anaphes) maxim sp. n. (Primorskii krai and Sakhalin Island), and Anaphes (Anaphes) rfe sp. n. (Primorskii krai and Beijing, China). Several historical records of some species of Anaphes in Russia are critically analyzed in the unfortunal absence of most voucher specimens, having in mind that some of them were likely misiden¬tified.

ON SOME REGIONAL FEATURES OF THE CONSEQUENCES OF THE IMPACT OF EXTREME EVENTS ON THE FOREST RESOURCES OF PRIMORSKII KRAI

Приморский край остается одним из ведущих производителей и экспортеров продукции леса в регионе Дальнего Востока. Между тем, динамика производства и экспорта ряда видов лесной продукции (особенно это касается недревесных лесных ресурсов) во многом зависит от благоприятных или неблагоприятных природных условий на территории края, тогда как колебания в производстве древесной продукции больше зависят от конъюнктуры мирового и отечественного рынков. Primorsii Krai remains one of the leading producers and exporters of forest products in the Far Eastern region. Meanwhile, a number of fluctuations in the production and export of a number of types of forest products (especially non-wood forest resources) largely depend on favorable or unfavorable natural conditions in the territory of the region, while fluctuations in the production of wood products are more dependent on the conjuncture of the world and domestic markets.

First record of the green lacewing Chrysoperla nigrocapitata (Neuroptera: Chrysopidae) from Russia

The green lacewing Chrysoperla nigrocapitata Henry, Brooks, Johnson, Haruyama, Duelli et Mochizuki, 2015 (Neuroptera: Chrysopidae) is recorded for the first time from Russia (Primorskii Krai: Kaimanovka). The feeding of full-grown larvae of this species on young, weakly chitinized larvae of Molipteryx fuliginosa (Uhler) (Heteroptera: Coreidae) is noted.

New for the Russian fauna species of the families Erebidae and Noctuidae (Lepidoptera)

Three noctuid species are found in Russia for the first time, of them two species, Bertula spacoalis (Walker, 1859) (Erebidae) and Euplexidia angusta Yoshimoto, 1987 (Noctuidae), are new for Primorskii krai, and Orthosia aoyamensis (Matsumura, 1926) (Noctuidae) – for Sakhalin Island.

First record of the hawk moths genus Psilogramma Rothschild et Jordan, 1903 (Lepidoptera: Sphingidae) for the fauna of Russia

The widely distributed hawk moth Psilogramma increta (Walker, 1865) is found in the south part of Primorskii krai in 2020. The genus Psilogramma Rothschild et Jordan, 1903 is recorded from Russia for the first time.
