Anaeromonadea

Anaeromonadea, also known as Preaxostyla,^[1][2] is a class of excavate protists, comprising the oxymonads, Trimastix,^[3] and Paratrimastix.^[4] This group is studied as a model system for reductive evolution of mitochondria,^[5] because it includes both organisms with anaerobic mitochondrion-like organelles (Trimastix^[6] and Paratrimastix^[7]), and those that have completely lost their mitochondria (oxymonads Monocercomonoides,^[8] Streblomastix, and Blattamonas^[6]).
