Gyrista je razdeo heterokontnih protista koji sadrži tri različite grupe: uglavnom fotosintetičku Ochrophyta, parazitsku Pseudofungi i nedavno opisanu grupu nanoflagelata poznatu kao Bigyromonada.^[2] Članove ovog tipa karakteriše prisustvo heliksa ili dvostrukog heliksa/prstena u cilijarnom prelaznom regionu.^[1]

Filogenija

Gyrista je viđena 2017. kao sestrinska grupa za tip Bigyra, koji sadrži Sagenista i Opalozoa. Zajedno, Gyrista i Bigyra čine nadrazdeo Stramenopiles ili Heterokonta.^[2]^[3]

Nopomene

^ Cavalier-Smith suggested that Sulcochrysis is possibly related to Olisthodiscus and grouped both genera within this subclass.^[8]^[2] However a study in 2021 reveals that Olisthodiscales is part of a new class Olisthodiscophyceae which includes only the genus Olisthodiscus. The position of the genus Sulcochrysis ostaje neizvesno zbog nedostatka DNK sekvenci.^[6]
