Abstract: This study describes the new Paleocene Rotaliid genus Bolivinoidesella of sample ODP 198-drilled on the Southern High of Shatsky Rise, Site 1210A- 24H-4(30–32), 219.70, Pacific Ocean, which located at tropical latitudes (~10oN) around the K/Pg boundary from lower bathyal–upper abyssal environment (1500–2000 m). It is characterized by finely perforate calcareous wall with elongate large biserial test, nearly globular chambers increasing rapidly as added, surface ornamented with wrinkles, sutures obscured in the lower part of the test, but slightly depressed in the upper part, narrow opening basal aperture. The new genus Bolivinoidesella differs from the genus Bolivinoides by elongate test, wrinkled rugose ornamented surface than rhomboidal test with longitudinal costae may bifurcated distally.
