Fifteen moss and lichen samples collected in localities of the Neuquen province, Argentina, contained tardigrades and their eggs. Eighteen species were found, three being new to science: Macrobiotus neuquensis sp. nov., Macrobiotus tehuelchensis sp. nov., and Minibiotus claxtonae sp. nov. Macrobiotus neuquensis sp. nov. can be differentiated from the other species of the harmsworthi group by the presence of a cuticular bar and a refractile zone in the first three pairs of legs. Also the… Expand
Tardigrades from Peru (South America), with descriptions of three new species of Parachela.
TLDR
The tardigrade fauna of Peru is discussed, a simple and economic system of describing relative lengths of pharyngeal macroplacoids is proposed, and a new species is identified that is most similar to I. baldii, but differs mainly by the absence of ventral sculpture. Expand
An integrative description of Macrobiotus shonaicus sp. nov. (Tardigrada: Macrobiotidae) from Japan with notes on its phylogenetic position within the hufelandi group
TLDR
A phylogenetic analysis of available DNA sequences of the COI marker for the hufelandi group revealed that the new species clusters with the two other species that exhibit filaments on egg process discs, which may suggest that the ancestor of the five species with atypical egg processes had a mutation allowing derivations from the mushroom or inverted chalice-like shape of egg processes.

Tardigrades from Nahuel Huapi National Park (Argentina, South America) with descriptions of two new Macrobiotidae species.
TLDR
Two new species of tardigrades, including a new 'pseudo-star'-shaped pores in the dorsal cuticle instead of fully developed 'stars' and by other morphometric characters are identified in the Argentinean province of Río Negro. Expand
The genus Milnesium Doyère, 1840 (Tardigrada) in South America with descriptions of two new species from Argentina and discussion of the feeding behaviour in the family Milnesiidae
TLDR
The study broadens the knowledge of tardigrades' feeding behaviour, provides some details about their diet and suggests that the type of prey chosen by some species belonging to the family Milnesiidae may be associated with the width of their buccal tube. Expand
New tardigrade records for the Baltic states with a description of Minibiotus formosus sp. n. (Eutardigrada, Macrobiotidae)
TLDR
A new species is identified from Estonia, Latvia and Lithuania, most similar to Minibiotus gumersindoi, but differs from it mainly by the presence of two types of cuticular pores, the absence of a triangular or pentagonal arrangement of pores above a single large pore on legs and a different macroplacoid length sequence.

Tardigrades from Larus dominicanus Lichtenstein, 1823 nests on the Argentine Islands (maritime Antarctic)
TLDR
Antarctic tardigrades are a very diverse group, and birds can be responsible for translocation of small invertebrates inside of various parts of plants and lichens and deposit large amounts of guano, which provides a lot of nutrients for poor tundra ecosystems and support small inverter communities. Expand
The morphological and molecular analyses of a new South American urban tardigrade offer new insights on the biological meaning of the Macrobiotus hufelandi group of species (Tardigrada: Macrobiotidae)
TLDR
Morphological and molecular data show that the Macrobiotus hufelandi group of species has to be considered a true biological entity; one of the more widespread tardigrade lineages in continental environments. Expand
Revisiting the genus Mesobiotus Vecchi et al., 2016 (Eutardigrada, Macrobiotidae) – remarks, updated dichotomous key and an integrative description of new species from Madagascar
TLDR
This paper analysed in detail the morphology of eggs, oral cavity armature and claws in all known Mesobiotus species, and provided a diagnostic key to the currently known species of the genus. Expand
New species of waterbear Minibiotus pentannulatus (Tardigrada: Macrobiotidae) from Colombia
Abstract The new species Minibiotus pentannulatus sp. nov., is described from the Sierra Nevada de Santa Marta, Colombia. It differs from the other species of the genus by star-shaped pores, theExpand
