Taxonomy

''Chlorokybus atmophyticus'' was once thought to be the only species in the genus.JSTOR The Zoospore of Chlorokybus Atmophyticus, a Charophyte with Sarcinoid Growth Habit
/ref> In 2021, a study showed that there were at least four other species, morphologically indistinguishable, but with deep genomic differences, suggesting divergences possibly about 76 million years ago. ''Chlorokybus'' has been found in Eurasia, Central and South America. ''Chlorokybus'' was placed in a new class, order and family. The new class Chlorokybophyceae was basal within the charophytes. Within the genus, the species were related as shown in the cladogram:
