Tardigrade Taxa
No full textThe list of tardigrade taxa up to a sub-generic level, with the type species
of each genus and the numbers of lower taxa in each taxon (known in the end of June
2018) is here presented together with the main environments in which taxa were
found.
Each listed taxon is characterized by characters common to all lower taxa using
predominantly most recent taxa definitions. Taxa definitions were eventually
adjusted using original descriptions.
This review of tardigrade taxa underlines as taxonomy and systematics of the
phylum are continuously updated by researchers and new species are constantly
discovered. Currently, there are 1265 species (2 of them fossil) of Tardigrada
belonging to 129 genera and 28 families including one fossil
