The work provides data on the dynamics of the abundance of 205 taxa from 19 genera: Cleptes, Colpopyga, Elampus, Omalus, Philoctetes, Pseudomalus, Hedychridium, Hedychrum, Holopyga, Chrysidea, Chrysis, Euchroeus, Chrysura, Pseudochrysis, Spinolia, Spinolia, including species rare and new for the fauna of the North Caucasus and Russia. By the nature of the population dynamics, five groups of cuckoo wasps were identified: spring – represented by 7 species from 4 genera; spring-summer – 76 species from 10 genera; summer – 113 species from 16 genera; summer-autumn – 4 species from 2 genera and spring-summer-autumn – 5 species from 3 genus. According to the duration of flight, eurychronous species of cuckoo wasps were identified, which are found throughout the season from spring to autumn; mesochronous – the years of which affect the end of May and summer months and stenochronous – confined to a short period of time. Eurychronic accounted for 2.4%, mesochronous 24.9%, stenochronic 72.7%. The number of generations of cuckoo wasps is related to the dynamics of the number of the host. In the mountains, the peaks of activity shift towards the middle of summer, most species have one peak of activity; due to the frequent changes in weather conditions in the mountains, the phenological characteristics of the cuckoo wasps and their hosts do not coincide in terms with the lowland populations and the periods of activity can be extended in time. Phenological characteristics of rare and new species for the fauna of the North Caucasus and Russia are presented for the first time. The data obtained expand the understanding of the biodiversity and dynamics of the abundance of cuckoo wasps in the North Caucasus and can be used for environmental protection measures and rational nature management in the south of Russia.

This paper describes for the first time the chromosome set of stone marten in the North Caucasus from two disconnected points. The karyotype did not show polymorphism, both in number and morphology of autosomes and heterochromosomes. In a double set contains 38 chromosomes. In addition, new data on distribution based on the cadastral map, which is compiled on karyologically dated material, taking into account the altitudinal-belt structure of mountain landscapes, is presented. Also, new materials on the dynamics of numbers taking into account the habitat, as well as current trends of anthropogenic changes in the structure of the stone marten habitat in the northern macro slope of the Central Caucasus. The study showed that stone marten is a very plastic species and can inhabit the territory of the northern macro slope of the Central Caucasus and that, in the presence of food and suitable shelters in almost all biotopes, including anthropogenic. The number of stone marten in the study area is highest in the forest-steppe and subalpine zones.

Analysis of ploidy and DNA content of Asplenium septentrionale s. l. from the Crimea, the Caucasus and Europe showed the presence of diploid forms. This allowed for the first time to draw a conclusion about the growth of Asplenium caucasicum (Fraser-Jenkins et Lovis) Viane in Europe and Russia, described from Asia. For the first time Asplenium onopteris L. was reorded in the North Caucasus.

Sphagnum mires on the Greater Caucasus are rare, characterized by the presence of relict plant communities of glacial age and are in a stage of degradation. The study of Sphagnum of Chefandzar and Masota mires is carried out for the first time. Seven species of Sphagnum are recorded. Their distribution and frequency within the North Caucasus are analyzed. Sphagnum contortum, S. platyphyllum, S. russowii, S. squarrosum are recorded for the first time for the study area and for the flora of North Ossetia. The other mosses found in the study area are listed.

The lichens and lichenicolous fungi of high mountainous landscapes of Samurskiy Ridge were studied in altitudinal range 2400–3770 m a. s. l. for the first time and 112 species are recorded. Among them 33 species, 10 genera (Arthrorhaphis, Baeomyces, Calvitimela, Epilichen, Lambiella, Psorinia, Rufoplaca, Sagedia, Sporastatia, Tremolecia) and 4 families (Anamylopsoraceae, Arthrorhaphidaceae, Baeomycetaceae, Hymeneliaceae) are new for Dagestan, six species (Buellia uberior, Carbonea atronivea, Lecanora atrosulphurea, Lecidea fuliginosa, L. swartzioidea, Rhizoplaca subdiscrepans) are reported for the first time for the Greater Caucasus and two species (Acarospora subpruinata and Rhizocarpon postumum) — for the North Caucasus. Most of the new findings were collected from 3500–3770 m a. s. l.

A Small collection of fossils from the Bokkeveld Beds has recently been sent to me for identification by the South African Museum, and some of them have been generously presented to the Sedgwick Museum. Amongst this material it is interesting to find some genera not previously recorded from the Cape and some new species. The majority of the specimens are in the condition of internal casts, and hence present especial difficulties in their determination, so that in a few cases some uncertainty must remain as to the generic position of the fossils. However, I am able to record for the first time from these beds the occurrence of the well-known lamellibranchiate genus Buchiola, and of a shell which may be identified with Nyussa arguta, Hall, of the North American Devonian. The genus Buchiola occurs in argillaceous nodules from the Zwartberg Pass crowded with individuals of the species which I have named B. subpalmata and with a few examples of an undetermined species. No other associated fossils can be recognised in these nodules, but I am informed that an abundant fauna is found in the beds at this locality.

A new self-pollinating species, Epipactis euxina, is described from Gelendzhik District of Krasnodar Territory. The species is closely related to E. persica from which it differs by its remarkable long pedicel, distinctly longer epichile, and indistinct or absent viscidium. It grows in sparse pine forest mixed with oak, on calcareous soils. Four other taxa collected in different localities of Krasnodar Territory are new for the North Caucasus: E. krymmontana, E. leptochila subsp. leptochila, E. leptochila subsp. neglecta, and E. muelleri. A new synonymy is proposed for E. persica = E. helleborine subsp. transcaucasica. An updated key to the species of the genus Epipactis in the North Caucasus is provided. The lectotype of E. muelleri is designated.

Pangrapta Hübner, 1818 was erected for the North American species P. decoralis Hübner, 1818 as its type species. The genus Pangrapta presently consists of about 100 species, and is widely distributed in China and surrounding regions, as well as in the New World (Hu & Wang, 2013). In this article, three new species, P. nanlingensis sp. n., P. jianfenglingensis sp. n. and P. hainanensis sp. n., are described from China. Each of them is superficially similar to the species, P. neorecusata (Hu & Wang, 2013), P. perturbans (Walker, 1858) and P. pannosoides (Holloway, 2005), correspondently. The known Southeast Asian species, P. shivula (Guenée, 1852), is reported for the first time from China. Adults and genitalia are illustrated. The type series of all described species (including holotypes) are deposited in Southwest University of Science and Technology (SWUST), Mianyang, China.

AbstractWe provide an updated survey for Sri Lanka of species of Graphis sensu Staiger, recently divided into Graphis s. str. and Allographa, including brief descriptions and a key to all 124 species currently known. Six new species are described: Allographa bambusicola Weerakoon, Lücking & Aptroot, a bambusicolous Allographa with entire labia, a laterally carbonized excipulum, 80–100 × 15–17 µm large, muriform ascospores and a rather thick, irregularly verrucose lateral thalline margin of the lirellae; A. weerasooriyana Weerakoon, Arachchige & Lücking, a corticolous Allographa resembling A. rustica Kremp. in overall anatomy and chemistry, but with a verrucose thalline margin of the lirellae and labia not distinctly raised above the thalline margin; Graphis flosculifera Weerakoon, Lücking & Aptroot, a corticolous Graphis resembling G. insulana but differing in the unique disposition of the lirellae and the slightly more elongate ascospores; G. rajapakshana Weerakoon, Lücking & Aptroot, a corticolous Graphis resembling G. desquamescens, including in ascospore size, but with lirellae with a distinct lateral thalline margin; G. rimosothallina Weerakoon, Lücking & Aptroot, a corticolous Graphis with a thick, uneven, rimose thallus and Fissurina-like lirellae, a completely carbonized excipulum and transversely 7-septate ascospores, 32–37 × 8–10 µm; and G. thunsinhalayensis Weerakoon, Arachchige & Lücking, a corticolous Graphis resembling G. subalbostriata but with smaller ascospores and lacking white lines between the striae of the labia. We also validate the name G. verrucoserpens Lücking. A total of 106 species are reported here for the first time from Sri Lanka. A biogeographical comparison with two other well-sampled countries (Costa Rica and Thailand) revealed a significantly higher similarity in species composition with Costa Rica than between Thailand and Costa Rica, suggesting a potential signature of the ‘biotic ferry’ hypothesis, that is the migration of lineages from Gondwana (partly corresponding to the modern Neotropics) via the north-eastwards drifting Indian subcontinent and subsequent interchange with Laurasia (partly corresponding to the modern eastern Paleotropics). However, the evolutionary timeline of the clades involved does not support this hypothesis and suggests an alternative explanation of geologically more recent mid- to long-distance dispersal.
