Granofilosea is a class of cercozoans in the subphylum
Filosa
Cercozoa is a phylum of diverse single-celled eukaryotes. They lack shared morphological characteristics at the microscopic level, and are instead defined by molecular phylogenies of rRNA and actin or polyubiquitin. They were the first major euk ...

Three groups that were traditionally considered
heliozoa
Heliozoa, commonly known as sun-animalcules, are microbial eukaryotes (protists) with stiff arms ( axopodia) radiating from their spherical bodies, which are responsible for their common name. The axopodia are microtubule-supported projections fro ...

Heliomonadida
The Heliomonadida (formerly Dimorphida) are a small group of heliozoan amoeboids that are unusual in possessing flagella throughout their life cycle.
