Macrobiotidae


Macrobiotidae is a family of tardigrades.

Phylogeny

External phylogeny

According to a 2018 report using multiple morphological and molecular studies, the Macrobiotoidea are sister to the Hypsibioidea; both are eutardigrades. The genera Adorybiotus and Richtersius were transferred from Macrobiotidae to a new family, Richtersiidae, in 2016.

Internal phylogeny

A 2021 phylogenetic analysis found that the genus Macrobiotus is monophyletic but that the former genus Xerobiotus is wholly contained within Macrobiotus. A new genus, Sisubiotus, was created. The genus "Minibiotus" was seen to be paraphyletic with respect to Tenuibiotus and Paramacrobiotus.
