Our analysis of specimens from the Pacific Ocean reveals a substantial similarity in wall structure with the genus Acarinina. In particular, the development and organization of the muricae, the hourglass shape of the pores, and the morphological features suggest that Pearsonites nov. gen. evolved from Acarinina in the late Paleocene. Herein we group three species previously considered morphologically and evolutionarily related to the Paleocene genus IgorinaDavidzon, 1976, within Pearsonites nov. gen.: P. broedermanni (Cushman & Bermudez, 1949), P. lodoensis (Mallory, 1959), and P. anapetes (Blow, 1979). Species assigned to Pearsonites nov. gen. are relatively common in the stratigraphic interval from the late Paleocene (Zone P5) to the middle Eocene (Zone E9).
