Abstract: Six Maastrichtian-Paleogene small Rotaliid benthic foraminiferal species of the genus Bolivinoidesella Anan are distributed in many localities in the Tethyan Atlantic and Pacific Oceans. This genus and its members differ from the other Bolivinoididae members in possessing numerous, delicate, irregularly anastomosing costae. This new assemblage are divided into two groups, Bolivinoidesella pacifica group and Bolivinoidesella salimi group. The first one includes four species: B. pacifica, B. karimae, B. olae, B. hudae, while the second group includes two species: B. salimi, B. ameeri. The modern taxonomic consideration of the six identified species, and the evolutionary trends of Bolivinoidesella spp. are presented and discussed. The prominent environment of the genus Bolivinoidesella and its members are most probably represents the lower bathyal–upper abyssal environment depth (~1500–2000 m).
