The article provides first records of 20 true bugs species (Heteroptera) from seven families (Lygaeidae, Miridae, Tingidae, Acanthosomatidae, Berytidae, and Saldidae) in Kemerovo Region, Western Siberia, Russia. These species, except two, are known in other regions of the Asian part of Russia, thus, the novel data clarify their up-to-date distribution. Most of true bugs, including an alien Hoplomachus thunbergii (Fallén) (i.e. 70% of all species in the study) were found in two botanical gardens (Kuzbasskiy and Orbita) in Kemerovo Region, highlighting the importance of surveying such plantings when running faunal studies and inventories. Two alien species, H. thunbergii (fam. Miridae) and Arocatus rufipes Stål (fam. Lygaeidae) originating from the European and Far Eastern parts of Russia respectively, were found in the city of Kemerovo and represent novel records for the Asian part of Russia (the former species) and Siberia (the latter species). These species could be introduced to Kemerovo Region with plants for planting, plant material or transported with human vehicles. Further studies would be needed to confirm this hypothesis. Here we provide short synopses of the bionomics, distributional records and trophic associations for all species newly documented in Kemerovo Region. The images of adults and male genitalia are given for the majority of species., The authors are grateful to Prof. R.V. Yakovlev (Altai State University, Barnaul) for his help and support on different stages of this study, A. Ustyuzhanina (Tomsk) for useful comments on early version of the manuscript. The contribution of V.V. Ru-doi and N.I. Kirichenko was supported by the Russian Science Foundation (project No. 22-16-00075) [species identification, distribution and trophic association data review, the manuscript preparation], N.N. Vinokurov was supported by the project of the Ministry of Science and Higher Education of the Russian Federation (project No. 0297-2021-0044) [verification of species identification].

In the paper based on materials of the Altai State University (Barnaul) and collections of the Institute of Systematics and Ecology of Animals of Siberian Branch of Russian Academy of Sciences (Novosibirsk), additional data on the distribution in the Altai Krai of 65 species of heteropterans from 13 families of the infraorders Cimicomorpha and Pentatomorpha are given. Bothrostethus annulipes (Herrich-Schaeffer, 1835) of the family Coreidae, presumably unintentionally introduced to Siberia, was found in Barnaul City area. Seven species are recorded for the first time for Altai Krai: Agnocoris rubicundus (Fallén, 1807), Closterotomus samojedorum (J. Sahlberg, 1878) (Miridae); Lasiacantha hermani Vásárhelyi, 1977, Tingis cardui (Linnaeus, 1758) (Tingidae); Scolopostethus pilosus pilosus Reuter, 1875, Raglius alboacuminatus alboacuminatus (Linnaeus, 1778) (Lygaeidae) and Ventocoris halophilus (Jakovlev, 1874) (Pentatomidae). Examples of aberrations of genital structures (male paramere and female parietal vaginal gland) detected in the Altai population of Nabis brevis brevis Scholtz, 1847 are discussed., The authors are grateful to the professor RV Yakovlev and AL Ebel (Barnaul) for the organization of the expedition in 2021. We also thank students of the Altai State University AE Naydenov, IA Sapozhnikova, RD Hivrich, MYu Bondarenko and volunteer AM Serebryakov (Barnaul) for the collection of the specimens.

Range, Kyzyldarya River valley, 40 km SE Shakhrizabs, 1200 m a.s.l., 22.v.1994, 1 ♂, F. V. Konstantinov lgt. (ZISP). Notes. Previously, M. tadzhika was known only from the Gissar Mts. Range of the Pamir-Alai mountain system in Uzbekistan and Tajikistan (Kiritshenko 1912; Cobben 1985; Vinokurov 2014a, b). A study of the Macrosaldula material from NMPC collected in the Hindukush Mts. revealed the spread of this species in Afghanistan. In most Afghan specimens, the pattern of the light spots on the corium is the same as in individuals from the Gissar Mts (Figs. 47, 48). The genital structures of males also have similar structure: for parameres and parandria, see Figs. 36–41, and for male grasping plate, Figs. 42, 43. In some dark specimens of M. tadzhika (Figs. 32–34), the spots on the corium resemble M. indica from North India. In M. indica, the dorsal side of the body also has long erect setae, but it is more shiny, and the apex of the clavus lacks a bright spot (Figs. 44, 49–53), the paramere is also curved, but the processus sensualis is not pronounced (Fig. 54), and the parandria are also widely spaced (Fig. 55). In dark M. tadzhika, a faint narrow spot remains present at the apex of the clavus and the processus sensualis of the paramere is slightly convex (Figs. 36–38). Distribution. West Pamiro-Alai (Tajikistan, Uzbekistan) (Vinokurov 2014a, b) and Hindukush (Afghanistan).

In Afghanistan, this species was collected in habitats similar to M. tadzhika. Macrosaldula nivalis differs from M. tadzhika by the short white pubescence on dorsum, absence of long erect black setae on pronotum and hemelytra (setae present only on the sides of the anterior margin of the pronotum). The hemelytra pattern is also different (Figs 23–25), but dark specimens of both species show great similarities (cf. Figs 26 and 32–34). In M. nivalis, the body of the paramere is straight, processus hamatus is thickened (Figs 27, 28), distance between parandria is very narrow (Fig. 29), penisfilum is coiled 1.5 times (Fig. 30), medial endosomal sclerite is as in Figs. 45 and 46, and the male grasping plate is as in Fig. 31.

Mandibular and maxillary plates brownish yellow, laterally darkened. Anteclypeus brownish yellow, black on basal half. Protibiae brownish yellow, meso- and metatibiae brown. Abdominal segments dark brown, narrowly yellow along lateral margin, with dense silvery setae. Variation. The two specimens from Bolshoy Chimgan fit well in the description of M. graziae sp. nov., but the black setae on scutellum, clavus and corium are as long as those on pronotum; the male also slightly differs in the shape of the parandria. For measurements, see Table 2. Differential diagnosis. Macrosaldula graziae sp. nov. is similar to the group of east Palaearctic species with completely dark coloured hemelytra���the South Far Eastern M. koreana and M. violacea, the South Siberian M. simulans, and the Siberian-Nearctic M. rivularia. Macrosaldula koreana and M. violacea share the shiny dorsum with M. graziae sp. nov., while M. rivularia and M. simulans have the dorsum matt. Externally, these four species differ by the very short dorsal setae (Figs. 18���22), while M. graziae sp. nov. has long erect setae on the dorsum. However, the resemblance to M. koreana and M. rivularia is only superficial, M. graziae sp. nov. does not belong to the ���aberrant group of species sensu Cobben (1985) ���, having a different structure of the medial endosomal sclerite. Of the Central Asian species of the genus, M. graziae sp. nov. is similar to M. tadzhika (Kiritshenko, 1912) by the presence of long erect setae on the dorsum of the body, but the latter species differs in the smaller body size, the presence of light spots on the corium, and the structure of the male genitalia (see Figs. 34���47). The extremely dark individuals of the Central Asian M. jakowleffi (Fig. 22) can be confused with M. graziae sp. nov. Macrosaldula jakowleffi has the same long erect setae on the head and pronotum, but differs from the new species by the following features: matt hemelytra with short erect setae on corium, processus hamatus of paramere attenuating evenly to the apex (Fig. 7), and pegs on male grasping plate dense (Fig. 8). A modification of the key by Vinokurov (2014a, b) is given below. Distribution. West Tian-Shan Mts. in Uzbekistan and Tajikistan. Modified key to the Macrosaldula of Russia and adjacent countries to accommodate M. graziae sp. nov. (modified from Vinokurov 2014a, b) 17 (18) Erect setae on metatibia longer than stout black setae. Pale spots situated on middle and at apex of endocorium, less frequently, at base; exocorium usually dark, with small pale spots at apex; in very pale specimens, corium with pale stripe along lateral margin (Figs. 12���15).

The Novosibirsk ERL is dedicated electron beam source for three free electron lasers operating in the wavelength range 8 - 240 micron at average power up to 0.5 kW and peak power about 1 MW. Radiation users works at 8 user stations performing biological, chemical, physical and medical research. The Novosibirsk ERL is the first and the only four-turn ERL in the world. Its peculiar features include the normal-conductive 180 MHz accelerating system, the DC electron gun with the grid thermionic cathode, three operation modes of the magnetic system, and a rather compact (6×40 m2) design. The facility has been operating for users of terahertz radiation since 2004. The status of the installation and plans are described., Proceedings of the 63th ICFA Advanced Beam Dynamics Workshop on Energy Recovery Linacs, ERL2019, Berlin, Germany

The radiation power of the FEL with optical cavity can be limited by the overheating of reflecting mirrors. In the electron outcoupling scheme electron beam radiates the main power at a slight angle to the optical axis. For this, it is necessary to divide undulator by a dipole magnet at least in two parts - the first for the electron beam bunching in the field of the main optical mode, and the second for the power radiation by deflected beam. Electron outcoupling system is installed on the third FEL based on the multiturn energy recovery linac of the Novosibirsk Free Electron Laser facility (NovoFEL). It consists of three undulators, dipole correctors and two quadrupole lenses assembled between them. There are two different configurations of the system since the electrons can be deflected in either the second or the third undulator. The electron beam dynamics calculations and the results of the first experiments are presented., Proceedings of the 63th ICFA Advanced Beam Dynamics Workshop on Energy Recovery Linacs, ERL2019, Berlin, Germany

Continuous wave (CW) 100 mA electron rf gun for injecting the high-quality 300-400 keV electron beam in Novosibirsk Energy Recovery Linac (ERL) and driving Free Electron Laser (FEL) was developed, built, and commissioned at BINP SB RAS. The RF gun consists of normal conducting 90 MHz rf cavity with a gridded thermionic cathode unit. Bench tests of rf gun is confirmed good results in strict accordance with our numerical calculations and showed reliable work, unpretentious for vacuum conditions and stable in long-term operation. The design features of different components of the rf gun are presented. Preparation and commissioning experience is discussed. The latest beam results are reported., Proceedings of the 63th ICFA Advanced Beam Dynamics Workshop on Energy Recovery Linacs, ERL2019, Berlin, Germany
