Ancyromonadida

provided by wikipedia EN

Ancyromonadida or Planomonadida is a small group of biflagellated protists found in the soil and in aquatic habitats, where they feed on bacteria.[1][2] Includes freshwater or marine organisms, benthic, dorsoventrally compressed and with two unequal flagellae, each emerging from a separate pocket. The apical anterior flagellum can be very thin or end in the cell membrane, while the posterior flagellum is long and is inserted ventrally or laterally. The cell membrane is supported by a thin single layer teak and the mitochondrial crests are discoidal / flat.[3]

The group's placement is doubtful, as it seems to fall outside the five supergroups of Eukarya.[4] Cavalier-Smith considers that they constitute a basal group to Amoebozoa and Opisthokonta and places it together with other related groups in Sulcozoa.[5] However, they appear more basal than Malawimonas, placing them in Loukouzoa, possibly as stem podiates, and depending on the placement of the root position of the Eukaryotes.[6][7]
