Classification of recently discovered amoeboid protists

Many groups of protists, also known as microbial eukaryotes, remain understudied. One such group, the superfamily Sainouroidea in the supergroup Rhizaria has been shown to be a molecularly diverse and divergent clade by recent environmental sequencing. Here we isolated and analyzed cultures of Saino...

Using a molecular species concept we described four novel genera and twelve novel species in Sainouroidea.
