An analysis of the mtCOI sequences in the species from the genus Ypsolopha Latreille, 1796 made it possible to confirm a new species for science, Y. occultatella sp. n., morphologically similar to the East Asian species Y. yasudai Moriuti, 1964. The genetic distance between the mtCOI sequences in Y. occultatella sp. n. and Y. yasudai is 0,066–0,069 (6,6–6,9 %). However, the minimal genetic distance, 0,038–0,042 (3,8–4,2 %), was determined between the mtCOI sequences of the new species and Y. blandella (Christoph, 1882), while these species differ well in the forewing pattern.

The Australian Mycodrosophila fauna comprises 21 species distributed in northern and eastern Australia to southern New South Wales. Only one species, M. argentifrons Malloch, is previously described from Australia; the south-east Asian species M. separata (de Meijere) is recorded for the first time. The remaining 19 species are new: adequate material has been available to permit the description and naming of 18 of them.

Cuticular features potentially offer valuable information on phytotaxonomy, especially for plants that are difficult to classify or identify. Cryptocarya is one such difficult and poorly known genus, and we investigated its cuticular features to evaluate their taxonomic implications. We examined cutinized leaf epidermis and the stomatal complex for 21 species from Peninsular Malaysia, Thailand and Indo-China, as well as one species endemic to Borneo and one to Sumatra, and compared features among members of this group, between this group and congeners in the other countries, and between this group and the other genera of Lauraceae. Many of the Cryptocarya species studied have straight to slightly curved anticlinal epidermal walls and butterfly-shaped stomatal ledges, although some variation was seen in the ornamentation of the periclinal epidermal walls and the appearance of the stomatal complex. Based on these results, we recognized four groups and two subgroups among the South-east Asian species. Comparison with congeneric taxa in the other countries indicates that butterfly-shaped stomatal ledges are often shared among the species across the regions. However, no cuticular features occur exclusively in any of the species groups of Cryptocarya studied here, nor in the genus as a whole. We consider that cuticular features are useful in the recognition of infrageneric groups within Lauraceae, bearing in mind that they might have evolved in parallel in different genera.

The article characterizes the formation and development of the Baikal Lake Basin, situated in the south of Eastern Siberia. Attention is also paid to processes of tectonic development of the Baikal region which have influenced the deepening of the Baikal Basin. The author studies in the same time erosional-denudational processes influencing the lake basin formation.

Four species of Strychnos are recognised for Australia (S. arboren, S. lucida, S. minor and S. psilosperma). The South-east Asian species, Strychnos axillaris is excluded from Australia, being regarded as extending no further south than New Guinea. A key to the Australian species, together with descriptions, distributional, habitat. and other notes are provided.

The Baikal region covers the territory of the south of Eastern Siberia and the northern part of Mongolia. Among the main anthropogenic ones that play the leading role in the transformation of the region’s animal population structure are overgrazing, plowing of fields, fires, invasions of alien species of animals, overhunting and chemical pollution. For ichthyocenosis, the determining factors of transformation are

Dragonfly Anax nigrofasciatus Oguma, 1915 (Odonata: Aeshnidae) was collected on a small pond in the vicinity of Vityaz settelment, Gamov Peninsula, Primorsky Krai in 2021. It is the first record of this East Asian species from Russia. A. nigrofasciatus clearly differs from A. parthenope julius Brauer, 1865, more common in the south of the Russian Far East, by body coloration and by details of morphology.

Mapping of hazardous geomorphological processes in the Baikal Region and its ecological and geomorphological zoning was carried out on the basis of the improved method, developed earlier by the authors. Baikal Region includes the subjects of the Russian Federation in the South Siberia and Republic of Mongolia within the boundaries of the Lake Baikal Basin. The basis of zoning are
