''Voromonas'' is a genus of predatory alveolates. The genus and species were described by Mylnikov in 2000. It was originally described as ''Colpodella pontica'' but was later renamed by Cavalier-Smith and Chao in 2004.


Taxonomy

There is one species known in this genus. A DNA based analysis suggests that this species may be related to the ''
Colpodella ''Colpodella'' is a genus of alveolates comprising 5 species, and two further possible species: They share all the synapomorphies of apicomplexans, but are free-living, rather than parasitic. Many members of this genus were previously assigned to ...
