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 (this name was preoccupied thus the new family was renamed to Richtersiusidae in 2021).
Internal phylogeny
A 2021 phylogenetic analysis found that the genus Macrobiotus is monophyletic (a clade) 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.
Genera
, the family Macrobiotidae consists of the following genera:
Biserovus Calcarobiotus C. (Calcarobiotus) C. (Discrepunguis) Famelobiotus Insuetifurca Macrobiotus Mesobiotus Minibiotus Minilentus Paramacrobiotus Lorena Rebecchi et al.: Resistance of the anhydrobiotic eutardigrade Paramacrobiotus richtersi to space flight (LIFE-TARSE mission on FOTON-M3).
