Specimens of the rare benthopelagic deep-water calanoid Pseudeuchaeta acuticornis Markhaseva et Schulz, 2006 (Copepoda: Calanoida: Aetideidae) were collected in the Kurile Kamchatka Trench area in the northern Pacific at abyssal depths. The morphology of these individuals aligns well with the diagnosis of the species. This is the first record of the species from the Pacific Ocean.
Markhaseva et Schulz, 2006 年在太平洋北部库里尔-堪察加海沟地区的深海深处采集到了罕见的底栖深水螅状纲 Pseudeuchaeta acuticornis（桡足目：螅状目：Aetideidae）的标本。这些个体的形态与该物种的诊断结果十分吻合。这是该物种在太平洋的首次记录。

This paper presents the results of a study and describes a new species of pelobionts, Pelomyxa pilosa sp. nov. (Archamoebae: Pelobiontida). This species was found in the bottom sediments of a pond near St Petersburg (Russia) and was examined using light, immunofluorescence, and transmission electron microscopy. It is placed in the genus Pelomyxa Greeff, 1874 based on a combination of morphological features, including the mode of locomotion, the presence of numerous flagella, the organisation of the cytoplasm, and the presence of obligate prokaryotic endocytobionts. The new species can be easily distinguished from congeners by the specific presence of numerous prokaryotic ectobionts on the cell surface and the organisation of the nuclear apparatus. The nucleolar material in this species forms a hollow sphere consisting of tightly adjacent patches of various shapes and sizes, surrounded by granular material.

Three nominal species of eelpouts endemic to the Sea of Okhotsk, specifically Lycodes ygreknotatus Schmidt in Taranetz, 1937, L. microlepidotus Schmidt, 1950, and L. fulvus Toyoshima, 1985, are reinvestigated based on all type materials and additional specimens. The latter two species are recognised as junior synonyms of L. ygreknotatus, as no significant morphological differences were found among these taxa. Lycodes ygreknotatus is rediagnosed. It exhibits significant geographic variability in both the number of vertebrae and the density of scale cover. The observed variability can likely be attributed to differences in environmental temperatures across different parts of its extensive distribution range.
根据所有模式材料和其他标本，重新研究了鄂霍次克海特有的三个标称种，即 Lycodes ygreknotatus Schmidt in Taranetz, 1937、L. microlepidotus Schmidt, 1950 和 L. fulvus Toyoshima, 1985。ygreknotatus 的初级异名，因为这些分类群之间没有发现明显的形态差异。Lycodes ygreknotatus 被重新诊断。它在脊椎骨数量和鳞片覆盖密度方面都表现出明显的地域差异性。观察到的变异可能是由于其广泛分布区不同地区的环境温度差异造成的。

Tephritis ruralis (Loew, 1844) and T. sahandi Mohamadzade, Korneyev et Khaghaninia, 2011 are recorded from Armenia for the first time. The morphological details of five species of Tephritis Latreille, 1804 [T. araileri Evstigneev, 2020, T. conaraileri Evstigneev, 2020, T. ruralis, T. sahandi, and T. truncata (Loew, 1844)] are illustrated in colour photos. It is shown that some Armenian specimens of T. ruralis have two hyaline spots in the pterostigma (as does T. truncata), unlike the European specimens of T. ruralis. The glans of the phallus of T. truncata is illustrated for the first time. Scorzonera rigida Auch. ex DC. is recorded for the first time as a host plant of T. araileri.

New data on the morphology, distribution and host plants of three species from the Terellia virens group are provided. Terellia freidbergi Korneyev, 2013 and T. ivannikovi Korneyev et Evstigneev, 2013 are redescribed based on fresh specimens having the body shape and colour characteristic of living flies. Terellia zerovae Korneyev, 1985 is recorded for the first time from Russia; T. ivannikovi, previously known from the Samara Province of Russia, is recorded for the first time from Armenia and from the Saratov and Ul’yanovsk provinces of Russia. Centaurea takhtajanii Gabrieljan et Tonjan is recorded for the first time as a host plant of T. ivannikovi. In Armenia, the larvae of T. freidbergi develop in capitula of C. kotschyi persica (Boiss.) Greuter, C. (Chartolepis) sp., C. polypodiifolia Boiss, C. daralagoezica (Fomin) Greuter and C. spectabilis (Fisch. et C.A. Mey) Sch.

We describe Tenuibiotus yeliseii sp. nov., a new tardigrade species from Svalbard, using morphological and morphometric analyses conducted with the use of light and scanning electron microscopy, as well as genetic analyses based on four molecular markers (three nuclear, 18S rRNA, 28S rRNA, ITS-2, and one mitochondrial, COI). A phylogenetic analysis of the genus Tenuibiotus Pilato et Lisi, 2011 is conducted using new data. In addition, the taxonomic significance of gibbosities on leg IV as a key character for species identification in Tenuibiotus is discussed. A key to the species of Tenuibiotus is proposed.

Adropion camtchaticum sp. nov. (Tardigrada: Eutardigrada: Itaquasconidae) is described. The type specimens of the new species were found in a moss sample collected on the Kamchatka Peninsula. The new species is most similar to A. scoticum (Murray, 1905), but clearly differs from the latter in the larger body size, thinner bucco-pharyngeal tube, the presence of teeth in the oral cavity, and toothed bases of claws of all legs. It is the first record of semiterrestrial tardigrades from the continental part of the Russian Far East.
