New subgeneric division of Chaetonotus is proposed, mostly basing on reconstruction of cuticular covering evolution. The largest subgenus Euchaetonotus Schwank, 1990 is redefined and its name replaced by Chaetonotus s. sir. The subgenera Bifasciculatella Schwank, 1990 and Diversichaetatella Schwank, 1990 are rejected and three new subgenera Primochaetus, Captochaetus and Marinochaetus are established. New or emended diagnoses of all valid subgenera are given.

It was observed that the density values of Gastrotricha fauna expressed by the number of specimens in 1 cm3 of sediment or by the number of specimens falling on 1 m2 of the bottom area, obtained by various sampling methods, are comparable. For samples drawn with a vessel from the surface layer of the sediment it was shown that a multiplier of 60 000 was essential.

Composition and abundance of Gastrotricha in lake psammon were studied and compared with those from other lake habitats. Samples were taken from April till October 2004 from 3 sites at the edge of zone frequently wetted by waves (hygropsammon) in a deep (38 m) mesotrophic lake situated in Łęczyńsko-Włodawskie Lakeland (south-eastern Poland). A total of 11 gastrotrich species belonging to Chaetonotidae family were found. Three species: Lepidodermella squamata Dujardin, Chaetonotus macrochaetus Zelnika i Ch. heideri Brehm dominated (52%) in total abundance. According to the previous studies the number of species occurring in bottom sediments of the same lake was higher by 11–14 species. Species diversity index H’, amounted 2.19 being lower than that calculated for the gastrotrichs of inshore bottom and littoral sediments (2.88 and 2.58, respectively) and similar to the value given for epiphytic fauna (2.01) of that lake. The fauna of psammic Gastrotricha showed the greatest similarity (38%) to epiphytic fauna of that lake as measured by the index of homogeneity. Peak densities of psammic Gastrotricha were found in May (37.5 10³ ind. m⁻²) and in September (32.8 10³ ind. m⁻²) and marked decrease of density was observed in August and October (18.1 10³ ind. m⁻² and 13.6 10³ ind. m⁻², respectively). Mean density and biomass were 25.35 10³ ind. m⁻² and 3.8 mg m⁻² respectively. Density and biomass of Gastrotricha were by two orders of magnitude lower in psammon than in bottom sediments of the lake.

Gastrotricha is a cosmopolitan phylum of aquatic and semi-terrestrial invertebrates comprising over 820 described species. Virtually no taxonomic or faunistic data exist on freshwater Gastrotricha of the Arctic. So far, 10 studies have recorded Gastrotricha from the entire area of the Svalbard Archipelago; only in two were gastrotrichs determined to the genus and species levels. The remaining studies only reported the presence of Gastrotricha as a phylum. In this article, I present the results of research on freshwater Gastrotricha from the area of fjord Isfjorden (Spitsbergen, Arctic). The collected material contained representatives of 8 species, 2 subgenera of Chaetonotus namely Chaetonotus (Chaetonotus) Erhenberg, 1830 and Chaetonotus (Hystricochaetonotus) Schwank, 1990, two genera namely Chaetonotus Erhenberg, 1830 and Bifidochaetus Kolicka et Kisielewski, 2016, both belonging to the family Chaetonotidae Gosse, 1864 (sensu Leasi and Todaro, 2008). I describe 3 new species from the Chaetonotidae: Chaetonotus (Chaetonotus) jaceki sp. nov., C. (C.) gelidus sp. nov., and C. (C.) svalbardi sp. nov., together with data on the range, frequency and abundance of all noted species. Furthermore, a record abundance of Gastrotricha was noted, amounting to more than one thousand specimens per 1 cm³ of bottom sediment.
