Abstract The fauna of bristletails of the genus Lepismachilis Verhoeff, 1910 in Montenegro and Serbia includes only one species L. (Berlesilis) targionii (Grassi, 1887) with 2 + 2 eversible vesicles on abdominal urocoxites II–VI. Three new species of this genus are described: L. (Lepismachilis) prijepolja sp. nov., L. (Lepismachilis) limensa sp. nov. from Serbia, and L. (Lepismachilis) alexandrae sp. nov. from Montenegro. All described new species belong to the species group of the subgenus Lepismachilis s. str. with 2 + 2 eversible vesicles on abdominal urocoxites II–V. Lepismachilis prijepolja sp. nov. differs from L. y-signata Kratochvíl, 1945 and L. notata Stach, 1919 by the color, drawings and ratios of the compound eyes; ratios of sensory field on fore femur of male, number of divisions of ovipositor. Lepismachilis limensa sp. nov. differs from L. hauseri Bitsch, 1974 and L. abchasica Kaplin, 2017 by ratios of paired ocelli, sensory field on fore femur of male; ratios and chaetotaxy of maxillary and labial palps. Lepismachilis alexandrae sp. nov. differs from L. abchasica by the drawings of the compound eyes; ratios of paired ocelli, sensory field on fore femur of male; number of divisions of the parameres and gonapophyses. A list of the Machilidae occurring in Balkan Peninsula is also provided.

The 2 new associations, Carici stantis—Salicetum reptantis and Salico-Polemonietum acutiflori, are described within the all. Caricionstantis of the class Scheuchzerio-Caricetea fuscae R. Tx. 1937 for the northern belt of the typical tundra subzone of Taymyr. The diagnostic species group of the first syntaxon includes plants typical of sites with excessive watering. The ass. Carici stantis—Salicetum reptantis is restricted to bottoms or lower parts of the watershed and moun­tain terrace slopes. The ecological regime of these sites is subject to slight variations reflected in presence/ absence of certain species. Due to floristic differences, the association is subdivided into several subassociations which form a topographic-ecological series along the humidity gradient: epilobietosum palustris→ptilidietosum ciliaris→typicum→petasitetosum frigidi. The ass. Carici stantis—Salicetum reptantis is referred to the all. Caricionstantis which also includes the associations Meesiotriquetris—Caricetumstantis and Pooarcticae—Dupontietumfisheri (also described from the Ragozinka R. basin); the latter occur in the wet depres­sions between sloping hills and the flowing valleys, respectively. If compared to these two, the ass. Carici stantis—Salicetum reptantis is shown to hold an intermediate position between them. The ass. Salico-Polemonietum acutiflori with the 2 variants, Salix lanata and S. reptans, represents various variants of mire vegetation which have under­gone zoogenic transformation (by lemmings). The stands size 1—1.5 m2 in space. The diagnostic species group comprises plants common of the wet mossy stream banks. The association is referred to the all. Caricion stantis, although many diagnostic species of the alliance are not present in its composition. When the new data are available, the association is probable to be separated into an independent alliance.

The Cercyon shinanensis species group with two included species is erected within the nominotypical subgenus of Cercyon Leach, 1817. This group is compared with other Palaearctic species groups of Cercyon s. str. The little-known C. shinanensis Nakane, 1965 from Japan (Honshu) is redescribed and its diagnostic features are given. Cercyon sundukovi sp. nov. is described from the Russian Far East (Kunashir Island).

Objective To collect computed tomography data of the laryngeal anatomy of Chinese men and to determine the feasibility of using the size 4 Ambu AuraOnce laryngeal mask (Ambu A/S, Copenhagen, Denmark) in Chinese men weighing >70 kg. Methods This prospective study involved men who underwent surgery from May 2018 to January 2019 at Jinshan Hospital. Pharyngeal and laryngeal parameters were measured by computed tomography. The laryngeal mask insertion success rate, requirement for tracheal tube insertion, laryngeal mask insertion time, fiberoptic bronchoscopy grading, air leakage pressure, and pharyngeal complications were analyzed. Results In a comparison of the size 4 and 5 Ambu AuraOnce devices, the first insertion success rate was 100% and 87% and the three-times insertion success rate was 100% and 93%, respectively, with no significant differences. However, the insertion time was significantly different at 19.6 ± 5.9 versus 31.1 ± 11.2 s, respectively, and the proportions of fiberoptic grading levels were also significantly different. There were no significant differences in the air leakage pressure or pharyngeal complications. Conclusion The size 4 Ambu AuraOnce is more adequate than the size 5 for Chinese men weighing >70 kg, with a shorter insertion time and higher fiberoptic bronchoscopic grading.
