We describe the new association Lycopo lucidi–Alnetum japonicae Korznikov, Verkholat & Krestov 2021 ass. nov. of the Alnus japonica swampy forests of the coastal plains and river valleys in the south of the Primorye Territory of Russia. The association includes two subassociations: Lycopo lucidi–Alnetum japonicae typicum Korznikov, Verkholat & Krestov 2021 subass. nov. and the preliminary delineated Lycopo lucidi–Alnetum japonicae betuletosum davuricae subass. prov. developing on gently sloping foothills with a lateral inflow of moisture and is transitional to zonal broad-leaved forests of the class Quercetea mongolicae Song ex Krestov et al. 2006. The association is classified to the alliance Fraxino–Alnion japonicae Miyawaki et al. 1977 described from Japan and belonging to the order Alnetalia japonicae Miyawaki et al. 1977 and the class Alnetea japonicae Miyawaki et al. 1977. We also validate the name of the association Stellario longifoliae–Alnetum japonicae Ohno in Miyawaki 1988 nom. inval. (art. 5) from Hokkaido Island, Northern Japan.

Wagnerinus frugivorus sp. nov. (Ceutorhynchinae: Ceutorhynchini) is described from Hokkaido, northern Japan, based on morphological and biological characters. Morphologically, this new species closely resembles Wagnerinus carinulatus (Faust) from the Russian Far East and W. costatus (Hustache) from Japan and Korea in having an emarginate anterior margin of the rostrum, sternite VIII diminished to a pair of small sclerites, and longitudinal rows of endophallic sclerites. However, it is distinctive enough to be distinguished from W. carinulatus and W. costatus mainly by the more conspicuous mucrones of mid and hind tibiae, deeper concavities of ventrites I and II, and larger paired prominences of ventrite V. Also, W. frugivorus clearly differs from W. costatus in terms of host plant utilization, the former feeds on the seed capsules of Weigela middendorffiana (Caprifoliaceae) as larvae, while the latter utilizes midge galls on the axillary buds of Weigela species. In addition to general taxonomic information, we provide a 1366-bp fragment of the mitochondrial cytochrome oxidase subunit I gene from the holotype as a DNA barcode of W. frugivorus and discuss the importance of DNA barcoding combined with species descriptions.

Subject. The article addresses the tax liabilities of taxpayers registered in the subjects of the Far Eastern Federal District, which should be paid to the consolidated budget of the Russian Federation, as well as the factors of the said debt growth. Objectives. Our aim is to assess the level of tax debt of regions of the Russian Far East and identify the correlation between the factors and the amount of tax debt. Methods. The study rests on methods of analysis, generalization, grouping, systematization, and the correlation and regression analysis. Results. We analyzed the level of tax debt for the entire Far Eastern Federal District and by region, identified factors affecting the growth of tax debt therein. The paper assesses the structure of tax debt by type of taxes and activity of debtors. The unveiled factors may help control changes in the size of tax debt in the Russian Far East and develop effective measures to improve the debt collection. Conclusions. The study shows that there is an increase in the tax debt in the regions of the Russian Far East, in the VAT in particular. The factor analysis revealed that the volume of sales of wholesale enterprises, investment in fixed capital, the consumer price index have the largest impact on the amount of tax debt.

The paper summarizes information on chromosome numbers (CNs) of the Grass species (Poaceae) in the flora of Russian Federation, obtained on the original material, most part - from the Russian Far East (RFE). In some species the CNs are known in Russia or in the world only from RFE, in some – from one locality or few, or from one subregion of RFE. The grass species in RFE often occur in mountain regions and near seacoasts; some species are endemics, some were studied near the limits of their geographical distribution areas. The diversity of CNs, the special features of the CNs distribution in some grass groups are discussed. The alien species are abundant in RFE, and their CNs are also involved in the study. For karyologically polymorphous species further studies are needed.
