REMARKS This species has oval basal plate of scales (1.7 × 1.3 µm) with annulus and long spine (4.95 µm) with acutely pointed tip. Our specimens could be identified as P. imperforata Lucas sensu lato. Scoble & Cavalier-Smith (2014) pointed out that the spine length of the marine species P. imperforata is 1 / 10 the spine length of P. acuminata which occurs in freshwaters.
