Citation: Chrysochromulina Lackey 1939 emend Edvardsen et al. 2011Rank: GenusType species: Chrysochromulina parva Lackey, 1939Taxonomic discussion: numerous species have been described in Chrysochromulina. Edvardsen et al. (2011) showed that several of these should be removed into a separate genus Haptolina, within the Prymnesiacea.The remianing species aredivied here into three groups:
definite Chrysochromulina - species shown by molecular genetics to belong in the clade containg the type species of the genus. These species typically have saddle-shepd cells
likely Pryms - species for which there is currently no molecular genetic data but which appear morpholgically likely to be members of the Prymenesiaceae.
Affinity not stablished - other species for which there is currently no molecular genetic data
