Evolutionary scenarios for the origin of an Antarctic tardigrade species based on molecular clock analyses and biogeographic data [PDF]
, 2017 The origin of the Antarctic continental extant fauna is a highly debated topic, complicated by the paucity of organisms for which we have clear biogeographic distributions and understanding of their evolutionary timescale. To shed new light on this topic,

Evolution of egg deposition strategies, exaptations of exuvia, and thanatochresis in tardigrades [PDF]
The cuticle is the tardigrade exoskeleton that, limiting animal growth, needs to be periodically shed. New cuticles must be formed (within the old ones) before getting rid of the obsolete exoskeletons at the end of moulting process.

Two New Species of Tardigrada From Moss Cushions (Grimmia sp.) in a Xerothermic Habitat in Northeast Tennessee (USA, North America), With the First Identification of Males in the genus Viridiscus [PDF]
, 2020 Background. The phylum Tardigrada consists of over 1,300 species that inhabit terrestrial, freshwater and marine environments throughout the world. In terrestrial habitats they live primarily in mosses, lichens, leaf litter and soil, whereas tardigrades ...

Revision of Angursa (Arthrotardigrada: Styraconyxidae) with the description of a new species from Japan [PDF]
, 2019 We re-examined the type material of five of the seven described species of the marine tardigrade genus Angursa Pollock, 1979, namely, A. abyssalis Renaud-Mornant, 1981, A. bicuspis Pollock, 1979 (type species), A. capsula Bussau, 1992, A.

Too many spines, or an integrative foundation of the Echiniscus spinulosus morphogroup (Heterotardigrada: Echiniscidae) [PDF]
Historical taxonomic bias has started to be effectively removed in tardigrade taxonomy in the last two decades by the application of modern statistical, genetic and morphological tools.

New Echiniscidae (Heterotardigrada) from Amber Mountain (Northern Madagascar) [PDF]
A moss sample from the local biodiversity hotspot in lowland rainforest in the vicinity of Amber Mountain, Madagascar, yielded the discovery of two Echiniscus C.A.S. Schultze, 1840 species, of which one is new to science. Echiniscus succineus sp. nov. is
