: Taxonomy of eight ampharetids of the tribe Amagini is discussed on the basis of huge museum collections of Moscow and St-Petersburg (more than 2000 specimens from about 250 samples). It is shown that species of monotypic genera Neopaiwa, Paiwa, and Weddelia are junior synonyms of Samythopsis grubei . Mexamage and Paramage are junior synonyms of Amage. Thus, the tribe includes genera Amage , Grubianella , and Samythop-sis. Amage levensteinae sp.n. , Amage clemi sp.n. , and Amage ceshici sp.n. from the abyssal depths are described. Amage asiatica , Grubianella klugei and Samythopsis grubei are re-described based on the type material. How to cite this article: Jirkov I.A. 2023.

The present paper sets to study the characteristics of trematode communities in the colonies of L. naticoides , formed under relatively unfavorable habitat conditions for the host at the northeastern border of the range, and to characterize the host-parasite relations. We revealed the parthenitae of Apophallus mue-hlingi , Apophallus (= Rossicotrema ) donicus , Parasymphylodora markewitschi ,

. The aim of this study was to evaluate the performance of Underwater Video Stations (UVS) to detect caddisfly larvae (Trichoptera), estimate density in a lake, as well as to evaluate its effectiveness in tracking larvae. For this, were deployed UVS. Recording a total of 3120 minutes of video were analysed, of which 968 min were used for abundance analysis. Finally, caddisfly larvae were tracked using the Tracker software, which recorded the velocity of everyone in mm/s. This work successfully put into practice a novel sampling methodology for this insect group. The technique was implemented quickly, easily, and inexpensively and is highly scalable for the monitoring of aquatic invertebrates. Remote video stations are a potential tool for use in the field of population monitoring and studies of personality and behaviour in the natural habitat.

: The gregarines from millipedes are diverse and understudied parasites. They are distributed across five families of eugregarines, but the majority of their species belong to family Stenophoridae, where their phylogenetic relationships are not well understood. Here we obtain 20 new gregarine sequences from millipede hosts and employ environmental sequence data to examine the phylogeny within the family. Phylogenetic analyses with SSU rDNA and combined SSU, 5.8S and LSU rDNA datasets recover all novel sequences as a monophyletic group consisting of six clades, five of which have not been recognized before. The stenophorids are sister to Gregarinoidea in the phylogenies, hence we redefine the group as Stenophoroidea Clopton, 2009. We describe four new species of Stenophora and show that the phylogeny of these gregarines does not follow the phylogeny of their millipede hosts.

: During the parasitological survey on the research vessel Professor Kaga-novsky , the western part of the Bering Sea and the southern part of the Sea of Okhotsk was investigated for fish infection by parasites. In total, 1083 specimens of 17 species of teleosts and salmon shark Lamna ditropis were dissected, in which 32 species of parasites were found. The plerocercoids Pelichnibothrium speciosum s. lato prevailed in the Bering Sea. In the Sea of Okhotsk, the maximum intensity and prevalence of infection were noted for P. specioum s. lato , Anisakis sp. and Echinorhynchus gadi s. lato . The difference in the number of studied fish species in the Bering and Okhotsk Seas (14 vs 9) significantly affected the species diversity of noted parasites (28 vs 18). Teleosts caught in the coastal area and the ones performing vertical migrations to some degree differed in terms of infection pattern, primarily due to digeneans component. Macroparasites of the crested sculpin Blepsias bilobus were studied for the first time, and 20 new records were made on the infection of previously studied fish species. Parasite fauna of fish in the epipelagic zone of the western part of the Bering Sea and the southern part of the Sea of Okhotsk is characterized by significant intensity, however, relatively poor species diversity.
在Kaga-novsky教授号科考船的寄生虫学调查中，对白令海西部和鄂霍次克海南部的鱼类进行了寄生虫感染调查。共解剖硬骨鱼和鲑鱼鲨17种1083份标本，其中发现寄生虫32种。Pelichnibothrium speciosum s. lato是白令海中最常见的复头鲸类。在鄂霍次克海，感染强度和流行率最高的是拉托棘球绦虫、异尖基斯绦虫和拉托棘喙绦虫。白令海和鄂霍次克海所研究鱼类数量的差异(14种对9种)显著影响了著名寄生虫的物种多样性(28种对18种)。在沿海地区捕获的硬骨鱼和进行垂直迁移的硬骨鱼在感染模式上有一定程度的不同，主要是由于digenes成分。首次研究了冠状鳍鱼的大寄生虫，并取得了20项新记录。白令海西部和鄂霍次克海南部上层海域的鱼类寄生区系强度较大，但物种多样性相对较差。
