Species of the genus Bertolanius (Eohypsibiidae, Eohypsibioidea) are morphologically very similar and can be distinguished by only minute differences. During faunal surveys in Arctic areas (Disko I., Greenland; Uummannaq, Greenland; Abisko, Sweden), the four species Bertolanius nebulosus, Bertolanius smreczynskii, Bertolanius weglarskae and Bertolanius birnae sp. nov. were found. Bertolanius nebulosus and Bertolaniussmreczynskii have been compared with their paratypes, and type material of… 
Integrative redescription of Hypsibius pallidoides Pilato et al., 2011 (Eutardigrada: Hypsibioidea) with the erection of a new genus and discussion on the phylogeny of Hypsibiidae
TLDR
An integrative redescription of Hypsibius pallidoides Pilato, Kiosya, Lisi, Inshina & Biserov, 2011 was undertaken following a reexamination of the type material and new material using high-quality light microscopy, scanning electron microscopy and methods of molecular taxonomy, revealing a unique complex of characters that precluded the attribution of this species to the genus Hypsibia Ehrenberg.
Revised Cornechiniscus (Heterotardigrada) and new phylogenetic analyses negate echiniscid subfamilies and tribes
TLDR
By integrative analyses of morphology and DNA sequences of numerous populations of a rare genus Cornechiniscus, it is demonstrated that Echiniscinae are diphyletic, as Bryodelphax forms a distinct phyletic lineage within EchinISCidae, and Pseudechiniscinee are polyphyletic.
Deceptive conservatism of claws: distinct phyletic lineages concealed within Isohypsibioidea (Eutardigrada) revealed by molecular and morphological evidence
TLDR
Claw morphology is reviewed and, for the first time, shown to encompass a number of morphotypes that correlate with clades recovered in the molecular analysis, and a dychotomous diagnostic key to all currently recognised isohypsibioid families and genera is provided.
First records of tardigrades (Tardigrada) from Irish and Scottish leaf litter
The findings of an investigation of the tardigrade fauna associated with beech (Fagus sylvatica) leaf litter in the Republic of Ireland and Scotland are reported. The present study is the first to
Analysis of Encystment, Excystment, and Cyst Structure in Freshwater Eutardigrade Thulinius ruffoi (Tardigrada, Isohypsibioidea: Doryphoribiidae)
TLDR
Encystment in tardigrades is seen as an adaptive strategy evolved to withstand unfavorable environmental conditions and is an example of the epigenetic, phenotypic plasticity which is closely linked to the molting process.

(2020). Analysis of Encystment, Excystment, and Cyst Structure
TLDR
Encystment in tardigrades is seen as an adaptive strategy evolved to withstand unfavorable environmental conditions and is an example of the epigenetic, phenotypic plasticity which is closely linked to the molting process.
Taxonomy, biogeography and ecology of Andean tardigrades at different spatial scales
Micrometazoans are animals smaller than 2 mm. Their biogeography is poorly understood, and tardigrades provide a tractable phylum for exploring distribution patterns at a variety of scales. Polylepis
Morphology and Functional Anatomy
TLDR
This chapter gives an introduction to the structure and function of major tardigrade organ systems, including the integument, body cavity, and digestive, muscular, nervous, and reproductive systems, and highlights the diversity of tardigade sensory appendages and overall external morphology.
The structure of tardigrade communities at fine spatial scales in an Andean Polylepis forest
ABSTRACT Little is known about distribution patterns of micrometazoan organisms at different spatial scales and the mechanisms driving these patterns across different environments. Here we explore

Eohypsibiidae (Eutardigrada, Tardigrada) from the Faroe Islands with the description of a new genus containing three new species
TLDR
The new genus Austeruseus is primarily found in mosses at high mountain biotopes, and the new genus may be a glacial relic.
Tardigrades from Portugal: four new records and description of two new species
Six species of Eutardigrada are recorded from Portugal; four of them, Macrobiotus crenulatus Richters, 1904, Hypsibius seychellensis Pilato, Binda & Lisi, 2006, Diphascon (Diphascon) pingue (Marcus,
Amphibolous weglarskae Dastych, a new addition to the Tardigrada of Iceland with an updated checklist of Icelandic species (Eohypsibiidae, Eutardigrada).
TLDR
An updated taxonomic checklist to Iceland's tardigrada species has been included because of the progress made since Morgan (1980) on the systematics of the entire phylum.
A New Species of Freshwater Tardigrades from Disko Island (Greenland) Increases an Unsolved Paradox in Tardigrade Systematics
TLDR
The discovery of this new species increases an unsolved paradox in tardigrade systematics related to the presence of closely related species which share a very similar morphology of the animals but clearly differ in their egg morphology, while, conversely, there are species belonging to different evolutionary lines that have similar eggs, but very different adult morphology.
Phylogenetic analysis of Macrobiotidae (Eutardigrada, Parachela): a combined morphological and molecular approach
TLDR
Neither morphological nor molecular analyses supports a monophyletic clade for the subfamily Macrobiotinae, whereas both support a well defined evolutionary line (Murrayinae) within the family.
Micrognathozoa: A new class with complicated jaws like those of Rotifera and Gnathostomulida
TLDR
Jaw‐like structures are found in other protostome taxa as well—for instance, in proboscises of kalyptorhynch platyhelminths, in dorvilleid polychaetes and aplacophoran mollusks—but studies of their ultrastructure show that none of these jaws is homologous with jaws found in Gnathostomulida, Rotifera, and Micrognathozoa.
A zoogeographic study of the limnoterrestrial tardigrade fauna on the Faroe islands
The Faroe islands (62°N, 7°W) are an archipelago of 18 small islands situated in the northeast Atlantic ocean between Iceland and the Shetland islands. A zoogeographic investigation (2001-2004) of
Encystment Processes and the “Matrioshka-like Stage” in a Moss-dwelling and in a Limnic Species of Eutardigrades (Tardigrada)
TLDR
Two species of eutardigrades from Italy have been considered: the moss-dwelling Amphibolus volubilis (Eohypsibiidae) and the limnic Dactylobiotus parthenogeneticus (Murrayidae), whose cysts are constituted by a series of cuticles surrounding the animals and resemble an onion or a Matrioshka Russian doll.
Tardigrades of the Taimyr peninsula with descriptions of two new species
TLDR
The almost complete absence of tardigrades in and around Norilsk is noted, related to the heavy industrial pollution from a local nickel-copper plant.
