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]
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]
Filogenetskom analizom 2022. pronađena je monofiletska Bigyromonada sestra Pseudofungi . „Bigyra” je parafiletska :[ 4]
Revidirana taksonomija Girista iz 2018. je sledeća,[ 2] sa uključivanjem novih klasa okrofita opisanih u 2020[ 5] i 2021.[ 6]
