Morphology wise, P. noduliferae has an overlall flattened shape, transverse surface folds and a flagellar apparatus, which is located at the apical end of the cell and contains two flagella (anterior and posterior) that move in a whip-like motion.

The Platyproteum genus had been formerly assigned to the Apicomplexa, but was later demostrated by Mathur and colleagues that it actually branched off from the base of the chrompodellid taxa and apicomplexan clade. P. noduliferae is sister to P. vivax (Yokouchi et al 2022).
