A heterotroph (; ) is an organism that cannot produce its own food, instead taking nutrition from other sources of organic carbon, mainly plant or animal matter. In the food chain, heterotrophs are primary, secondary and tertiary consumers, but ...

It includes the species ''Ancyromonas sigmoides'',
first described by
Saville Kent in 1880. The genus was rediscovered in modern times by Hänel in 1979.
They are about 5 μm long and live in both marine and freshwater habitats with a global distribution.
In 2008, Cavalier-Smith et al. proposed the reassignment of all known species of ''Ancyromonas'' into a new genus, ''Planomonas''. ''Planomonas'' has since been described as a junior synonym of ''Ancyromonas''.
''Ancyromonas'' does not belong to any of the eukaryotic supergroups, and they appear more basal than
Malawimonas
''Malawimonas'' is genus of unicellular, heterotrophic flagellates with uncertain phylogenetic affinities. They have variably being assigned to Excavata and Loukozoa. Recent studies suggest they may be closely related to the Podiata.

Loukouzoa, possibly relatives of podiates, and depending on the placement of the root position of the Eukaryotes.
