Ancyromonas is a genus of Varisulca. It is a flagellate.[1]

It includes the species Ancyromonas sigmoides.[2]

Planomonas has been described as a junior synonym of Ancyromonas.[3] 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.[4][5]
